Current Radar with Watches and Warnings
Below is our latest forecast thinking on the timing and magnitude of the severe threats through the start of the new week.
Severe Weather Forecast
Sunday Night- Thunderstorms with heavy rain and flash flooding will be ongoing from Kansas to central Texas.
- Any severe t-storms are most likely in parts of central and eastern Texas.
- Large hail, damaging winds, and possibly a tornado are the threats with any of these t-storms in Texas.
- Clusters of t-storms will continue overnight from Kansas to central and east Texas and into western Louisiana, with a serious threat of flash flooding and a few severe storms as well. This may include parts of the I-35 corridor.
- Cities: Okla. City | Dallas | Austin | San Antonio | Houston
Sunday Night's Thunderstorm Forecast
- Thunderstorms with flooding rain may be ongoing in the morning from eastern Nebraska to central and eastern Texas.
- The best chance of severe t-storms will be in parts of central and southeast Texas, with hail, high winds and a few tornadoes possible.
- Overnight, another cluster of t-storms is possible in parts of central or southeast Texas. Some of these storms may be severe with hail and high winds, but flash flooding may be the most serious threat.
- Cities: Dallas | San Antonio | Houston | Corpus Christi
Monday's Thunderstorm Forecast
- The chance for a few severe storms may linger in central and southern Texas.
- Some pockets of locally heavy rain may also continue to impact the south-central states.
- That said, the overall threat of flooding and severe weather will be less than previous days.
Severe Setup
A swirling area of low pressure in the upper levels of the atmosphere over the Four Corners and southern Rockies has run into a "road block" in the pattern over the East, namely, an "omega block" of high pressure, causing the low to stall and become cutoff from the jet stream.The flow between the two systems has transported moist air northward through the Plains, while lobes of energy eject northeastward around the upper-level low.
Thus you have moisture, instability, wind shear (change in wind direction with increasing height) and a source of lift (dryline - a boundary between dry southern High Plains air and moist air) needed for severe thunderstorms.
Friday's Storm Reports
As of Friday night, tornadoes have been reported by storm spotters in Eads, Colorado and near Guymon, Oklahoma. Storm chasers reported multiple additional tornadoes in the Oklahoma panhandle. There were 10 reports of tornadoes, according to NOAA's Storm Prediction Center.A helicopter for WSVN 7 News also captured video of an apparent dust devil or possible tornado in West Miami-Dade, Florida on Friday.
Saturday's Storm Reports
Late Saturday afternoon, a storm spotter reported a brief tornado in northwestern Kent County, Texas. A second tornado was also reported near Hermleigh, Texas Saturday evening. Severe thunderstorms even produced large hail to the size of golf balls in Texas on Saturday, including in Big Spring and near Clarendon.Snapped An Awesome Shot? Share Your Photo!
