Once again, after a day of heavy rainfall and tornadoes here in Maryland, we are looking at severe weather possibility Wednesday evening into Thursday. The key word for this event is timing, especially on Thursday. Simply stated, what we have is a frontal boundary stalling near us (around the MD/PA line depending on the model you follow) and an approaching cold front on Thursday. The timing issue deals with how quickly the atmospheric conditions come together on Thursday. The sooner the clouds move in and the rain begins the less severe the storms will be since there would be no daytime heating to further destabilize the atmosphere. But the opposite is true; if the storms hold off until later Thursday, and the sun is allowed to heat the atmosphere, then there is a possibility for us to see some severe weather later Thursday. I will know more about Thursday come later Wednesday, but be aware of the potential for severe weather Thursday afternoon.

TIMING: Wednesday later in the afternoon the rain should start and the storms will follow. The system is moving in from the west. Strong thunderstorms could occur anytime after 6 and last through Thursday.

LOCATIONS (for which I forecast): Central and S MD are in the mix Wednesday and Thursday, although it appears that on Thursday S MD could take the brunt of the strongest weather (not to say other areas wont experience strong storms).

THREATS: Heavy rain with flash flooding, hail, strong damaging wind and tornadoes.

I will have another update later Wednesday. Keep an eye on the sky and follow me on Twitter (@wxmanmd) for frequent storm and weather updates.
