Sunshine, plus temperatures well into the 60s today and tomorrow will make it seem like spring has arrived. But with spring-like weather comes the inevitable clash of warm air from the south and lingering cold from the north. Severe weather building in the South today will move our way Tuesday, bringing plenty of rain and even a chance of a thunderstorm Tuesday night. 

Severe weather is forecast today from East Texas east into Tennessee. We will likely be reading shortly of wind damage, heavy downpours and perhaps some tornadoes to our south and west. Here's the forecast for Jackson, Miss.

We remain on the back side of the high-pressure system that has kept us in sunshine for several days. The clockwise circulation around the high is drawing warm, moist air our way from the south and west. That will push our temperatures to 65 or so this afternoon, and a few degrees warmer than that tomorrow. The records are safe, but it will seem very spring-like - about 15 degrees above the seasonal norms.

By tomorrow afternoon, the severe weather will be crossing Alabama and Georgia and rain will spread into the Ohio Valley and the mid-Atlantic states ahead of a cold front.

The threat of heavy rain, on top of a rapidly melting snow cover in Maryland's western mountain counties, has prompted the National Weather Service to post a Flood Watch for Garrett County. They could see 1.5 to 2 inches of rain out there in Maryland's Lake Country, beginning late Monday night and continuing into Tuesday.

UPATE: The Flood Watch has been extended across all of central Maryland, from Tuesday afternoon through Wednesday morning. Here's more.

Earlier: We have no snow to melt here, of course, but we will see enough rain to run the risk of some flooding in low urban settings and poor drainage areas, forecasters say. They're talking about an inch or so down here.
