A disturbance developing across the nation’s midsection will track east, affecting the eastern half of the US late-week. Since spring is near and temperatures are gradually rising, snow will be limited, with rain instead the main story.
The first signs of this disturbance will be present today as showers develop across portions of the central and southern Plains. These showers will be quite light and scattered in nature, as this disturbance is in its very first stages of development. There may also be a very spotty, severe storms that form late in the day and into the overnight, especially near the Texas and Oklahoma Panhandles.
By Thursday, however, a line of moderate rain with some embedded thunderstorms will form near the Gulf Coast and the lower to mid Mississippi River Valley. The heaviest of rain will be closer to the coast thanks to the region’s proximity to the Gulf of Mexico.This area will also see the highest risk for severe weather. The Storm Prediction Center has highlighted the area from Arkansas through extreme-eastern Texas and the western Florida Panhandle as at risk for strong, dangerous storms. There won’t be an outbreak of severe weather, but strong winds and large hail will be possible in addition to a few tornadoes.
As we get into Friday, the rain will reach the East Coast. By this point in time, the severe weather threat will have ended, but a few thunderstorms will still be possible in the Southeast. Rain will be possible on Friday from New York through Florida, illustrating how widespread this area of moisture will be. Meanwhile to the north, a quick-moving low pressure system will be sweeping through southern Canada. That moisture will interact with pockets of cold air in the Great Lakes region and northern New England, leading to some snow. The best chance for this snow will be Friday night in the Green and White Mountains as well as across northern and central Maine. A general 1-3 inches of rain can be expected.
By Saturday, despite a few lingering rain and snow showers in New England, the rain will have left the Eastern Seaboard. This will provide the region with a dry day before a new storm develops, taking aim at the eastern US Sunday into Monday with more rain and thunderstorms.
