The week ahead: Warm and maybe a little stormy to start, unusually cool weather for Mother’s Day

/ May 3, 2020 at 10:36 PM

We’ll go from abnormally warm to abnormally cool in the course of these next seven days as a very late-season shot of Canadian air comes down the eastern half of the country in time for Mother’s Day. First, though, we continue with our more summer-like conditions to start the week. A cold front will sag south during the day on Monday, helping to drive temperatures back into the upper 80s out ahead of it with the potential for some showers and storms along it. The front will meander in the area for a couple days, and as upper-level disturbances traverse it, it is possible that we may see some showers and thunderstorms.

Another front swings through Wednesday, cooling us off back into the upper 70s, followed by a reinforcing shot of cooler, drier air for the weekend as an unusually cold airmass of Canadian (and perhaps Arctic) origin surges southward into the eastern half of the Lower 48, sending temperatures well below mid-May normals in the low 80s. While we won’t see any frost or freeze concerns, you won’t have to go too terribly far north to find some! In fact, it is conceivable that the current NWS highs might be generous if some of the ensemble members are to be believed. Regardless, though, Mother’s Day should look pretty good across the Lowcountry!
