The Mid-Atlantic states have been in a period of cooler weather since the beginning of March. While April did have a few warm days, the warmer temperatures did not last and sunk back into the 50’s and even 40’s. This week, however, temperatures are expected to near 90ºF by Thursday. While Sunday will be the coolest day, the forecasted high temperatures will continue to rise until after Friday. The weekend is expected to be nice with temperatures hanging in the 70’s. To put this into perspective, the average temperature for the month of April is 70ºF while the average temperature for the month of May is 78ºF.
A low pressure that is currently sitting over the New England states is the culprit for bringing the cooler temperatures and windy conditions to the Mid-Atlantic states on Sunday. The low pressure is expected to move off of the coast by tonight which will allow the warmer temperatures from a high pressure (that will be centered to the southeast of the region). High pressures rotate clockwise in the Northern Hemisphere, so this high pressure will grab ahold of the warmer temperatures near the Gulf of Mexico and push them northward into the region. This same system will also be the culprit of severe weather in the Midwest.
The lack of rain coupled with low humidity will serve as the ingredients for fire weather. Even though some areas received two to four inches with the past two weeks worth of storms, the wind has dried much of the area out. Winds can also play a factor as they can help spread the fire faster. The next chance of showers will be on Friday lasting through at least Sunday.
Even though temperatures are expected to reach into the upper 80’s this week, the Mid-Atlantic states still need to get through Sunday night. The winds should diminish, and the clouds should clear, making conditions conducive for dew or frost. Because temperatures will drop into the 30’s, frost will be the likely visitor. For anyone who has already started their garden, make sure you either bring them in, or cover them so the frost won’t kill them.
