ACCUWEATHER - Isolated strong-to-severe thunderstorms may impact afternoon and evening plans across portions of the mid-Atlantic on Wednesday.
Widespread severe weather is not anticipated, but a few stronger thunderstorms could produce wind gusts over 45 mph, which would produce wind damage in spots.
Cities that may be impacted by gusty thunderstorms include Philadelphia, Pittsburgh and Harrisburg, Pa., Baltimore, Md., and Washington, D.C.
Travelers along Interstate 95, 81, 83 and 76 should be prepared for rapidly changing weather conditions, including heavy downpours and strong, gusty winds.
The ingredients for these thunderstorms will come together as the day progresses. A warm front will push warmer, more moist air into the mid-Atlantic this morning.
Then, as a cold front moving down from the northwest interacts with this more moist air mass, scattered showers and thunderstorms will develop during the afternoon hours and continue into the evening.
Despite the increase in moisture, the air mass still will not be humid enough to support widespread strong-to-severe thunderstorm development.
Because of this, the thunderstorms will be spotty with some places even staying dry during the afternoon and evening. However, any thunderstorm that does form could produce wind gusts over 45 mph and lead to wind damage in some spots.
People with outdoor plans across the mid-Atlantic on Wednesday afternoon or evening should watch for a changing sky and head indoors if thunder is heard.
The front moving through is the same one that helped produced the wild temperature swings over the Plains states over the past couple of days. While it will be noticeably warmer on Wednesday, temperature changes across the mid-Atlantic will not be nearly as impressive.
The cold front leading to the thunderstorms on Wednesday will slowly drift southward on Thursday, bringing drier weather to much of Pennsylvania. However, the front will still be close enough to spark a few thunderstorms around Baltimore, Md., and Washington, D.C.
