A cool front will inch across the area later today and tonight and it will become the focus region for slow-moving showers and thunderstorms in the Mid-Atlantic region. Any storm that forms later today can become strong-to-severe with the potential of heavy downpours and damaging wind gusts. The front will stall out south of here on Thursday and its proximity will keep us unsettled late this week and during the weekend. Temperatures will not be as warm today as they were during the past couple of days and highs will likely hold in the 80’s right through the upcoming weekend. Elsewhere, the eastern Atlantic is looking quite active and we may have a tropical storm to monitor in the western Atlantic around this time next week.

Today is likely to be the hottest day of the week with high temperatures in the low-to-mid 90’s along with plenty of sunshine and humid conditions. The chance of showers and thunderstorms will increase later today and tonight, and then rise even further on Wednesday as a cool front approaches from the northwest. Any thunderstorm that forms over the next 24-36 hours can produce heavy rainfall at times. This front will stall out later in the week just to the south of here and this will keep us unsettled for much of the second half of the week. After reaching the 90’s this afternoon, temperatures will likely be confined to 90 or below for highs during the remainder of the week.

There is no extreme heat and humidity in sight, however, like that which we experienced last weekend.

The Mid-Atlantic region will finally get a break in the action with respect to the very wet weather pattern of recent weeks. Large high pressure will take control of the weather today and it looks like it can stay close enough to give us generally rain-free conditions right through the upcoming weekend. Temperatures and humidity levels will continue to be quite comfortable for late July as we progress to the weekend. The weekend promises to be quite warm and humidity will creep up, but not at all like the excessive heat and humidity of last weekend.

The hot weekend weather will transition to below-normal temperatures by tomorrow in the Mid-Atlantic and the adjustment will lead to showers and thunderstorms as a cold front approaches from the Great Lakes. Some of the storms later today and tonight can be strong-to-severe and there can be torrential rainfall with flash flooding. Following the frontal passage, highs on Tuesday and Wednesday will likely be confined to the lower 80’s which is actually below-normal for late July and some 15-20 degrees cooler than the extreme heat of the past weekend. The much more reasonable weather pattern in terms of temperatures will likely last through the remainder of the month of July in the Mid-Atlantic region.

The next three days will likely be the hottest stretch all summer long in the Mid-Atlantic region with urban areas along Route I-95 likely to make a run at the 100 degree mark (e.g., DCA, PHL, NYC) over the weekend. (Philly Airport hasn’t reached the 100 degree mark in the last 7 years). There is significant relief coming to the Midwest, NE US and Mid-Atlantic region next week and temperatures are quite likely going to be below-normal on Tuesday and Wednesday. The transition from the extreme heat and humidity expected this weekend to the cooler-than-normal conditions next week may very well come with strong-to-severe thunderstorm activity in the Sunday night to early Tuesday time period with more torrential rainfall and potential damaging winds.

The end of the 3-day heat wave may come with some strong-to-severe thunderstorm activity on Sunday night and/or Monday. By next Tuesday, temperatures will be below-normal and the overall temperature pattern looks pretty favorable going into at least early August with additional comfortable air masses on the way for the central and eastern US.
