Grab those rain boots and umbrellas because Friday is going to be a wet one.
March is going out like a lion. A large storm system that stretches from Canada to the deep south will deliver heavy rain to the entire Philadelphia area Friday into the vening, which could lead to localized flooding. Add in gusty easterly winds and you've got the recipe for a dreary end to March with the potential for making the evening commute challenging.
Since thunderstorms with heavy downpours rolled through overnight, rain has been steady at times, but mainly light. That will change starting Friday afternoon when waves of potentially heavy rain arrive. The first line of heavier rain will move in by mid-afternoon. The heaviest rain will likely fall during later afternoon and evening hours.
By late Friday night, the rain will still be falling but it won't be as heavy.
Rain will finally end Saturday morning, but by then 2 to 3 inches of rain will have fallen. With that much moisture falling over a long period of time and the potential for heavy rainfall when many are heading home from work and school, we have issued a First Alert for the possibility of localized flooding.
River and streams are already on the rise and roadways that usually have issues with ponding are likely to cause traffic headaches. Rain showers will continue to weaken overnight, and then finally end Saturday by 9 a.m.
The rest of Saturday will be dry, but cool as clouds linger. Sunday will be warmer with bright sunny skies.
April is just about to kick off, and that means more rainy periods to come. We’ll update you on the next possible round with a new blog soon!
