The Pacific Northwest and northern California will continue to experience an active and unsettled weather pattern, at least through midweek.
If you are looking for warmth, head to the Southeast, where much of the week will be dry, as well.
1) Thunderstorms Will Rumble Across Parts of Central and Eastern U.S.A cold front will push through the East into Monday, bringing showers and thunderstorms from the Northeast into parts of the South.
Another low-pressure system will move into the Plains Monday into Tuesday with another round of rain and thunderstorms, but no widespread severe weather is expected.
Early Week Forecast
Another disturbance will move from the Plains into the East in the mid-to-late week timeframe, bringing more showers and storms. That system could lead to an uptick in severe thunderstorm activity in the Plains and Midwest by Wednesday.

Locally heavy rain is possible through midweek, especially in areas of the central Plains into the upper Midwest.
2) Severe Threat Increases Late Week?Late this week, another area of low pressure will move from the Southwest into the southern Plains. There are some indications that this system will bring more of a threat of severe thunderstorms.
This low-pressure system will likely move into the central or southern Plains late this week or early next weekend.

Given the active pattern and that this late-week system is several days away, the forecast details will change, so be sure to check back to weather.com for updates.
3) Unsettled Conditions Persist in the Pacific NorthwestSeveral disturbances will bring wet weather to portions of the Pacific Northwest through Thursday.
Rain developed once again in northern California on Sunday, with snow falling at elevations above 6,500 feet in the Sierra. Rain and higher-elevation snow will spread into Oregon, Washington, northern Nevada and Idaho by Monday morning.
This Week's Forecast
Rainfall totals through Thursday will generally be less than 2 inches, while snowfall in the highest elevations of the Sierra and Cascades could reach a foot.

The good news is that none of these systems are expected to be particularly strong, as the most notable aspect of this pattern is that this extended period of unsettled, wet weather is not typical in mid-to-late April in northern California. However, it is not all that surprising given the record-wet water season that has been experienced this year.
4) Warmer-Than-Average Temperatures Will Prevail in the SouthAbove-average temperatures will begin the week from the Mississippi Valley to the East Coast. The Northeast saw highs up to 30 degrees warmer than average Sunday.
After the first cold front pushes through the Northeast by Monday, temperatures will return closer to average. However, many areas from the central and southern Plains into the Southeast and mid-Atlantic will see the warmth persist into midweek.
