The temperature reached the 90s a day earlier than what we had anticipated, and now today with the greater threat for some strong thunderstorms this afternoon, there could be enough clouds to prevent the temperature from returning to the lower-90s. We will keep the previous forecast of 88 that was made/altered yesterday afternoon, which is still quite warm.
The 91 at BWI yesterday still is the HOTTEST DAY at this location since Sept. 25 of last year. As we had anticipated the thunderstorms that bubbled up in the afternoon managed to stay to the north and the west of Baltimore. In fact, there were portions of Maryland’s western Panhandle that got hit very hard by some of these thunderstorms (like near Hagerstown, and in places like Cumberland and Frostburg). Today, there is a greater risk of strong thunderstorms near the I-95 corridor, and the Storm Prediction Center has its slight risk area located near Baltimore. With the influx of very warm and moist air being drawn toward a slow-moving front that will be pushing across the eastern Ohio Valley today and across the central Appalachians tonight and tomorrow, there will be some locally heavy downpours, and the storms later today may also bring some strong wind gusts.
The chances for a thunderstorm are still in the forecast for tomorrow, but it then looks as if the rest of the Memorial Day Weekend will be hot and humid, and mostly rain-free. I’d put the chances of getting a thunderstorm around here late on Monday at 20 percent or less. Hot through Tuesday, but some changes are on the way for the middle of next week. Have a great holiday weekend !!!!
