Light to moderate rain today gives way to storms on Wednesday.
A sturdy umbrella, rain boots, and a NOAA Weather Radio will be your best friends this week as a very unsettled weather pattern sets up across the region. The same storm system that produced deadly tornadoes on Sunday in Arkansas and in Mississippi yesterday is now impacting D.C. The good news is that we will be in the cool sector of the storm today, keeping the risk of severe weather to our south. However, dynamics change on Wednesday.
The warm front starts lifting northward tonight and will bring heavy rainfall. On Wednesday, the front will be north of the region ushering in warmer, moist, unstable air. Thunderstorms Wednesday afternoon and evening may bring damaging winds and isolated tornadoes. There is a slight risk from the Storm Prediction Center for those severe storms highlighted in yellow.
Rainfall amounts will range from 2-4" widespread through Thursday morning. Rivers, creeks, streams and urban areas may flood. A Flash Flood Watch is in effect from 10p.m until Late Wednesday night.
As we look at the month of April, the region is running a rain deficit. However, we will get more than what we need.
A few showers are possible early on Thursday, then the cold front clears the region and we end the week dry.
