An active weather pattern is setting up for the I-95 corridor for later today/early tonight extending all the way from the Carolinas to New England. There is an approaching vigorous wave of energy in the upper part of the atmosphere that will combine with diurnal heating and an advancing surface frontal boundary zone to destabilize the atmosphere over the next few hours and the result will likely be widespread showers and thunderstorms between about 2 and 9 PM in the I-95 corridor. Any storm that forms later today can produce torrential rainfall, flash flooding, and perhaps even damaging wind gusts. Looking ahead, a second frontal system will pass through the region early Friday and it’ll be followed by a much more comfortable air mass for the weekend with noticeably lower humidity levels.

A strong cold front will approach the region later today and it’ll increase the chance for showers and thunderstorms and some of the storms late today/early tonight can be on the strong side with heavy rainfall. A secondary cold front will arrive early Friday and it’ll usher in a much more comfortable air mass for the Philly metro region that will stay around this weekend. The drier air mass headed our way for the weekend will be anchored by strong high pressure to the north and west of here.

An active couple of days is in store for the Mid-Atlantic region with scattered showers and thunderstorms today and more widespread showers and thunderstorms later tomorrow. There is a wave of upper-level energy setting off some powerful and slow-moving thunderstorms at mid-day along the Delaware River region of the Mid-Atlantic and an even stronger system will likely generate numerous showers and thunderstorms later tomorrow into tomorrow night. Any of these thunderstorms can produce heavy rainfall and flash flooding given the well-saturated grounds. Looking ahead, a beautiful air mass for August will arrive on Friday and provide comfortable weather conditions for the weekend.

A cool front has stalled out south of here and the result will be more unsettled weather as we head into the upcoming weekend. There is the threat for showers and thunderstorms both today and on Saturday and any storm can produce heavy rainfall. The front may slip southward some later in the weekend which should lead to a lessening chance of rain as we close out the weekend. Temperatures during the next few days should be confined to the 80’s for afternoon highs.

The Mid-Atlantic region has experienced generally rain-free conditions over the past several days, but heavy downpours are on the table for this afternoon and evening. A cool front is edging this way and the result will be slow-moving showers and thunderstorms this afternoon and evening. Any slow-moving shower or storm can produce heavy rainfall amounts in a relatively short period of time and some of the storms can reach severe levels potentially producing damaging wind gusts. Given the still well-saturated grounds in the Mid-Atlantic region, any heavy rainfall can result in flash flooding conditions.
