4 Things To Know About the Severe Weather Threat This Week

Linda Lam
Published: April 26,2016

Severe thunderstorms have already impacted portions of the Plains and Midwest this week and the threat is not over yet. After the strong midweek system, another disturbance will once again bring the risk of dangerous storms to end this busy week.
Here are four things to know regarding the threat of large hail, tornadoes, damaging winds and heavy rainfall, as we head through Saturday.
(MORE: Severe Forecast Through Wednesday)

1.) The Threat of Severe Weather Lasts All Week


Late Week Setup
The low pressure system that brought severe thunderstorms to the Plains on Tuesday will continue to bring severe weather through midweek from the Mississippi Valley into the South and Ohio Valley. This system is expected to push off the East coast later this week.
Then, yet another system will move into the Southwest and the Plains to end the work week. This next system will be accompanied by the threat of severe thunderstorms beginning Thursday night in Texas, as well as parts of Oklahoma, and the threat will spread eastward into the weekend.

Five Day Forecast
It is too early for details on where severe weather will be found Friday and Saturday but portions of the southern Plains and South will likely be the target area for another round of severe thunderstorms.
(MORE: Late Week Severe Threat)

2.) Heavy Rain Is a Concern By Late Week


Rainfall Forecast
Locally heavy rain is expected within some of the thunderstorms that develop this week, which will likely become a concern later this week. When the next low pressure system moves into the southern Plains and the Mississippi Valley at the end of this week in addition to the chance for severe weather, the chance for heavy rainfall will also increase. This will likely result in the threat of flash flooding late week and into the weekend.
The heaviest rainfall through Saturday is expected in eastern Texas, southeastern Oklahoma, northwestern Louisiana and central and southern Arkansas. Much of this area will see rainfall totals of 3 to 5 inches and totals may top 5 inches in those areas by the weekend.
This is an area that does not need additional rainfall after already experiencing flooding earlier this year. Therefore, with the ground saturated any heavy rainfall will likely lead to flooding.
(MORE: Major Flash Floods Over the Past Year Texas, Louisiana, Arkansas and Oklahoma)
According to the National Weather Service in Shreveport, Louisiana, "rainfall amounts through the week could total between 3 to 6 inches with isolated higher amounts closer to 8 inches over the Red River Basin of northeast Texas and southeast Oklahoma."

3.) Severe Threat Lowers As System Moves East


Stormy Midweek Forecast
The chance of tornadoes, large hail and damaging winds will still be prevalent each day through at least Saturday. However, it currently does not appear that severe thunderstorms will be as widespread as on Tuesday.
The midweek system is expected to weaken as it presses eastward, although large hail, damaging winds and a few tornadoes will remain possible, especially on Wednesday.
Later this week, as the next disturbance moves into the Plains and Mississippi Valley, scattered severe thunderstorms will develop once again. An outbreak does not seem likely at this time, but given that this next event is still a few days away, the forecast may change so check back with weather.com for your latest forecast.

4.) The Area at Risk is Familiar With Tornadoes in Late April

Areas shaded red have the highest probability of seeing tornadoes in late April.
(SPC)
Later this week, the threat of severe thunderstorms will return to the areas that typically are at the greatest risk for tornadoes toward the end of April.
The map above from Storm Prediction Center shows the tornado probabilities across the Lower 48 for April 26 based on data during the period 1982-2011. Areas shaded in red from north Texas into Oklahoma and Kansas have historically had the highest probability of tornadoes this time of year.

Pattern Shift Brings 3 Changes Next Week

Linda Lam
Published: April 29,2016

Changes are coming in the week ahead due to a shift in the weather pattern. The changes will be particularly welcome to the severe weather weary Central U.S.
Active weather has been the story this past week, with rounds of severe thunderstorms in portions of the Plains, Midwest and South, as well as snow in the Rockies. Next week will be a different story as the jet stream lifts northward, allowing a ridge of high pressure to build over the central U.S. At the same time a southward dip in the jet stream, or upper-level trough, over the East will develop. The consequences of this shift will be a few changes in the weather heading into next week.
Here's a closer look at three changes we are watching for next week.

1.) Drier Days Ahead


Next Week's Forecast
The threat of severe thunderstorms and flash flooding will continue into the weekend in parts of the southern Plains, Mississippi Valley and South. This next round comes after storms have already brought severe weather to the region earlier this week.
(MORE: Severe Weather Impacts Late April)
Wet weather will linger into early week in the South and East. Thunderstorms are likely, especially toward the Gulf Coast, but the chance for severe thunderstorms will decrease.
By midweek, the risk of showers and thunderstorms will be confined to the East Coast. High pressure will move into the Plains, bringing a stretch of dry weather to the central U.S.
This area of high pressure will slide eastward late in the week, resulting in dry conditions for areas east of the Rockies. This is good news for the water-logged areas of the South, as this weather pattern will give areas the opportunity to dry out a bit and clean up any storm damage.

2.) Spring Returns to the South


Forecast Highs Early Next Week
Portions of the South have been enjoying a taste of summer this past week due to high and low temperatures that have been 10 to 15 degrees above average.
Highs have soared into the 80s and even a few lower 90s this week and low temperatures have only dipped down into the 60s and 70s, serving as a reminder that summer is right around the corner. These warm temperatures have been courtesy of high pressure, which has allowed a southerly flow to bring the warmer conditions into the South.
The warm temperatures will not last much longer, however, as the ridge of high pressure will slide eastward and an area of low pressure will approach from the west. The result will be slightly cooler temperatures, along with the chance of showers and thunderstorms.
(FORECASTS: Atlanta | Charleston, South Carolina | Jackson, Mississippi)
Temperatures will be closer to average for early May, but for many areas the temperature difference will be 10 to 15 degrees compared to the end of this past week. Highs next week will typically be in the 70s, with 80s toward the Gulf Coast. Lows will also be slightly cooler with temperatures dropping into the 50s for much of the South, with 60s toward the Gulf Coast and Florida.

3.) Warmer Days Ahead


Forecast Highs Compared to Average
Another area of the country that will see some of the big changes next week are the Rockies.
An area of low pressure is bringing snow to the Rockies and parts of the High Plains to end April. Over a foot of snow is possible in some of the highest elevations of Colorado, with even the Denver area seeing some snow accumulation.
(MORE: Late-April Winter Storm)
Snow showers may linger through this weekend in parts of Wyoming, Colorado and northern New Mexico. Accompanying the snow will be chilly temperatures. High temperatures will be up to 30 degrees below average into early next week in the Rockies and portions of the Plains.
Mid-to-late week, the upper-level trough will be replaced by an upper-level ridge of high pressure. This will translate into warmer and drier conditions for the region.
(MAPS: 10-Day Forecast)
High temperatures will be up to 20 degrees above average by late next week in the Rockies and northern Plains. Temperatures are expected to climb into the 80s as far north as Montana. Denver will go from seeing highs in the 30s on Sunday to highs near 80 by Thursday.
The warmer temperatures will also spread into the central Plains and the Upper Mississippi Valley to end the work week.

10 Dead As Kenyan Apartment Collapses Amid Heavy Rains

Associated Press
Published: April 30,2016

At least 10 people have been killed in Kenya and dozens were injured after an apartment building in Nairobi collapsed during heavy rains Saturday.
Hours-long traffic jams caused by flooded roads delayed rescue teams trying to reach the scene, said Japheth Koome, Nairobi's police chief, who confirmed the death toll.
The Kenya Meteorological Dept. issued a "heavy rain and storm advisory" for Wednesday and Thursday including Nairobi, for the potential of at least 1.5 inches of rain in a 24-hour period, weather.com senior meteorologist Jonathan Erdman said.
Kenya Red Cross personnel work at the site of a building collapse in Nairobi, Kenya, Saturday, April 30, 2016. A six-story residential building in a low income area of the Kenyan capital collapsed Friday under heavy rain and flooding, trapping an unknown number of people in the rubble, Kenyan officials said.

April is typically the wettest month of the year in Nairobi, averaging 8.64 inches of rain, Erdman said. This is due to the northward migration of the "intertropical convergence zone" through the area, a zone of rising air, heavy rain and thunderstorms near the equator where the Earth's easterly trade winds converge and rise.
The Kenya Red Cross said a search team managed to pull three children and an adult from the remains of the six-story building in the Huruma area.
The Red Cross said 150 building units and adjacent homes were affected.
Live TV footage showed the National Youth Service and firefighters removing stones by hand and a crowd cheering as a child was removed from the rubble.
Jacob Kiruma, who said he lived in the house adjacent to the one that collapsed, said the building was constructed "shoddily."
The structure had been built in less than five months and the 126 single rooms were quickly occupied at a rent of $35 a month, Kiruma said.
Area legislator Stephen Kariuki said this was the second building to collapse in a year. He blamed the county government of failing to follow through with demolitions of buildings that were identified as unfit for humans.

Because of a high demand for housing in Nairobi, some property developers bypass building regulations to cut costs and maximize profits. The Architectural Society of Kenya has estimated that 50 percent of structures in Nairobi are not up to code.
President Uhuru Kenyatta last year ordered an audit of all the buildings in the country to see if they are up to code after eight buildings collapsed, killing at least 15 people.
The report from the audit by the National Construction Authority found that 58 percent of buildings in the capital were unfit to live in. The majority of Nairobi's people live in low-income areas or slums.

Late-April Winter Storm Sweeps Through the Rockies and High Plains, Including Denver

Tom Moore
Published: April 30,2016

Despite the calendar switching to May, more snow will fall in the Rockies and High Plains this weekend.
The latest in a series of late-season winter storms that have been riding into the western U.S. from the Pacific has already dumped up to 20 inches of snow in the mountains of Colorado, and there's more to come.
The weight of this heavy, wet snow downed power lines and tree branches in Holyoke and Julesburg, Colorado, and also downed branches in Alliance, Nebraska. Up to 8 inches of snow had been measured in Julesburg as of early Saturday.
Two inches of snow had fallen at Denver Int'l Airport northeast of the city through Friday night, and 2.4 inches had fallen in Cheyenne, Wyoming.

Estimated Snowfall, So Far
Snow will continue through Sunday in the central and southern Rockies, and through Saturday night in the High Plains of western Nebraska, Wyoming, and parts of northeast Colorado as one sluggish upper-level low slowly moves out, but is replaced by another rotating out of the Desert Southwest.
Slush or snow-covered roads are possible in areas of heavier snowfall rates, particularly in the higher elevations, including the famously difficult stretch of Interstate 80 between Laramie and Cheyenne, Wyoming, which was closed by an accident early Saturday.

Current Radar
In the Denver metro area, the snow may mix with rain at times with perhaps an inch or so of additional accumulation expected, mainly on grassy areas. Although the snow will taper off, wind gusts could reach 25 mph along the Front Range Saturday.
The heaviest additional accumulations will be either in the higher elevations from northern New Mexico into Colorado and Wyoming, or where High Plains snow is most persistent in western Nebraska and southeast Wyoming. Another 6 inches of wet snow may fall in these areas through Saturday night or Sunday.
For the rest of the High Plains, only an additional inch or so is expected.
(FORECAST: Denver | Cheyenne)

Additional Snowfall Forecast
Forecasting can be tricky this time of year with lower elevation snowfall accumulations because the sun angle is so high and temperatures will be near, or slightly above, freezing. Snow has a tough time accumulating during the daylight hours and it accumulates better at night in these locations.
As a result, snow in some areas has been mainly confined to grassy surfaces in these areas and there has been some melting or compaction of the snow, as well.

Severe Weather Outlook

Saturday
  • Severe thunderstorms are possible from the mid-Mississippi Valley and Lower Ohio Valley to the northern Gulf Coast.
  • Threats: Damaging wind gusts, large hail and perhaps a few tornadoes. How much severe weather there will be remains uncertain given the widespread nature of clouds and rain which may hold down instability. Once again, heavy rainfall also will be a concern and could cause flooding in parts of Arkansas, east Texas, Louisiana and Mississippi and west Tennessee.
  • Cities: Houston | Memphis | New Orleans

Saturday's Thunderstorm Forecast
Sunday: 
  • Locally heavy rain and a few severe storms may impact a swath from the mid-Atlantic and Southeast to the Gulf Coast.
  • Overall the potential for severe storms will be much lower than previous days, however gusty winds and hail will still be possible. Heavy rain may also cause localized flash flooding, particularly in the Lower Mississippi Valley and near the Gulf Coast, saturated from the past few days of heavy rain.
Monday:
  • Once again, any severe t-storms should be relatively few and far between from the eastern Carolinas to south Texas.
  • However, areas of locally heavy rain and flash flooding may persist in the Lower Mississippi Valley and western/northern Gulf Coast.
Below is the rainfall forecast through Monday. Keep in mind that locally heavier amounts of rain can fall in short periods of time than what is shown on the map.
The heavy rain falling on already saturated ground is likely to produce additional flooding.

Weather Underground Forecast for Saturday,April 30,2016

A low pressure system will transition across the Mississippi Valley on Saturday, while a separate system deepens over the Southwest.

An area of low pressure will move east northeast across the southern Plains and the middle Mississippi Valley. Warm and moist air will collide with this system, which will generate widespread rain and thunderstorms across the Plains, the Midwest and the Deep South. Severe thunderstorms will be possible in eastern Texas, Louisiana, Arkansas, northwest Mississippi, western Tennessee, western Kentucky, southern Illinois and southeast Missouri. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Heavy rain will also bring threats of flash flooding to the lower Mississippi Valley and the central Appalachians. In addition, a mixture of rain and snow will persist across the central Rockies and the central high Plains.

Another area of low pressure will move southward over California and northern Mexico. This system will generate showers and isolated thunderstorms across parts of California and the Desert Southwest. Rain and high elevation snow will also develop from the Sierra Nevada to the Rockies. A ridge of high pressure centered over the West Coast will bring dry conditions to northern California and the Pacific Northwest.

Rain to ease unusual northeastern US dryness but to put a damper on outdoor plans

By , AccuWeather.com Senior Meteorologist
April 29,2016; 11:25PM,EDT
 
 
Expanding rainfall will bring good news for unusually dry portions of the northeastern United States into early next week. However, rain will spoil outdoor plans and keep temperatures down for those seeking spring warmth.
Rain is needed to erase the short-term deficit that has set the stage for abnormally dry conditions across portions of the eastern U.S. Moderate drought conditions are gripping portions of southwestern Pennsylvania, West Virginia and Virginia, according to an April 26 report issued by the United States Drought Monitor.
The dry conditions have many stream levels low for the middle of spring.

"Even after the wet weather into Friday, many areas from Virginia to part of New York state and southern New England have received only about 50 percent of their average rainfall since March 1," according to AccuWeather Senior Meteorologist Brett Anderson.
In recent days, enough rain has already fallen and prompted increased greening of some vegetation in West Virginia, Virginia, Maryland, Delaware, Pennsylvania, Ohio and parts of New Jersey and Michigan to ease brush fire concerns due to the dry conditions.
About an inch of rain fell on much of the Shenandoah National Park, Virginia, where the Rocky Mountain Fire has consumed 10,300 acres but is now 90 percent contained.
After a southwestward retreat of wet weather into Saturday, rain will expand farther north on Sunday and continue into Monday.
"In most areas, Saturday will be the best bet for outdoor plans in the Northeast," according to AccuWeather Chief Meteorologist Elliot Abrams.
The rain will fall Saturday night to Sunday night in parts of the central Appalachians, with totals of 1-2 inches.
The rounds of rain from Sunday to Monday will also average 1-2 inches in the mid-Atlantic and 0.50 to 1 inch in New England and upstate New York. Locally higher amounts are possible from West Virginia to southern New Jersey and Delaware.

The rainfall will not totally erase the deficit everywhere, but it will help boost soil moisture and stop the decline of stream levels.
The rain will wash also away dust and pollen in the short term.
People who don't mind shopping at garden or home improvement centers in rainy weather may find the lack of crowds to be a bonus.

The negative aspects of the wet weather will range from disrupting outings, sports and activities to causing minor travel delays. The rain and clouds will also hold temperatures back.
Enough rain could fall on parts of the mid-Atlantic from Sunday to Monday to cause minor street flooding. Low cloud ceilings could lead to minor airline delays, especially in the Interstate-95 cities from Washington, D.C., to Philadelphia, New York City and Boston.
Locally heavy thunderstorms can also occur, mainly south of the Mason-Dixon Line.
With the Canadian air on the retreat in the short term, it will not feel quite as harsh as that of the middle days of this past week, despite more rainfall.
AccuWeather RealFeel® Temperatures will be 10-20 degrees Fahrenheit higher this weekend into early next week, when compared the middle of this past week. Rain and/or the chilly air resulted in RealFeel Temperatures in the 30s and 40s for a time this past week.
The weather will dry out a bit during the middle part of next week, ahead of another round of showers that will span multiple days. A new batch of chilly air may rotate southeastward from Canada along the the showers.

Severe storms to elevate flood risk in Oklahoma, Texas and Arkansas

By , AccuWeather.com Senior Meteorologist
April 29,2016; 11:23PM,EDT
 
 
Following an outbreak of severe thunderstorms at midweek, more storms will ignite over the southern Plains into the weekend. The additional storms will elevate the risk of flash flooding.
The storms will impact a portion of the Interstate-35 corridor that was hit by violent weather on Tuesday.
After isolated severe thunderstorms erupted on Thursday night, the severe weather threat will broaden over the southern Plains and into part of the Mississippi Valley into Friday night.

During this time, the potential for dangerous and damaging storms will extend from central Texas and much of Oklahoma, eastward into parts of Arkansas and Louisiana.
Into Friday night, cities at risk for severe weather include Dallas and Austin, Texas; Little Rock, Arkansas; and Oklahoma City.
A tornado was reported near Ninnekah, Oklahoma on Friday afternoon. AccuWeather Extreme Meteorologist Reed Timmer was tracking the storm live on the ground and reported of damage after the tornado lifted.

The storms will bring the potential for damaging wind gusts, large hail, frequent lightning strikes and isolated tornadoes.
The slow-moving nature of the storm system, combined with the repeating nature of the thunderstorms will also bring an elevated risk of flash flooding.

Localized flooding could develop in the Houston area, which tends to flood often during heavy rain events.
"The most likely time for flooding problems around the Houston area will be from before dawn Saturday into Saturday evening," according to AccuWeather Senior Meteorologist Dan Kottlowski.
The pattern will deliver a general 3-6 inches of rain on parts Louisiana, Arkansas and Texas. Of that rainfall, a couple of inches could fall in as many hours on some communities.
The risk of severe thunderstorms and potential flash flooding will shift slowly eastward and expand northward as the weekend progresses.
During Saturday, the threat for severe thunderstorms will extend from Houston and Lake Charles, Louisiana, northward to Little Rock, Memphis, Tennessee; and St. Louis.

By Sunday, the threat of flooding downpours and locally severe thunderstorms will extend as far north as the Ohio Valley and as far south as the Mississippi Delta region.

Rain to put a damper on Walpurgis Night, May Day festivities in Germany

By , Senior Meteorologist
April 29,2016; 11:17PM,EDT
 
 
Rain will threaten to put a damper on Walpurgis Night and May Day festivities across parts of Germany this weekend.
Showers and thunderstorms will arrive on Saturday and evolve into a steadier rain by Walpurgis Night across southwestern Germany, including in Stuttgart, Frankfurt and Saarbrücken.
The rain will pour down heavily at times, threatening to douse bonfires and other activities.
While central and northwestern parts of the country will receive a couple of showers, Berlin and Munich will stay dry. Anyone heading outdoors on Saturday night will need a jacket as temperatures fall to 3-7 C (37-45 F).

People dressed as a devil, left, and a witch, right, dance in front of the Walpurgis fire after a procession of devils and witches in the Harz mountains in Schierke, Germany, on 30 April, 2014. Hundreds of costumed devils and witches meet to celebrate Walpurgis Night, a traditional religious holiday of pre-Christian origins. The event is named after St. Walburga, an English nun who helped convert the Germans to Christianity in the 8th century. (AP Photo/Jens Meyer)
The rain from Saturday night will taper to spottier showers for May Day in central and southern Germany. Residents will want to keep umbrellas handy and prepare for some disruptions to outdoor activities.
The showers, however, will be light and spotty with parts of the day being dry. Around North Rhine-Westphalia, the showers will even dissipate by the afternoon.

The best place to enjoy May Day across Germany will be in northern areas from Bremen to Hamburg and Berlin. Sunday will feature dry conditions as some sunshine mixes through clouds.
