The month of August will likely end up with very close-to-normal temperatures in much of the Mid-Atlantic region and Northeast US and it looks like September will get off to cool start. Indeed, a cool blast of air will push into the Upper Midwest and Great Lakes region later this weekend and then arrive in the Mid-Atlantic region and Northeast US on Monday, Labor Day following the passage of a couple of cold frontal systems. The initial cold front this weekend will likely result in numerous showers and thunderstorms later Saturday and Saturday night across the northeastern states and then a secondary cold front can produce some shower activity on Sunday and Sunday night. By Monday and Tuesday, highs will be confined to the 70’s across the Mid-Atlantic/NE US and overall humidity will be at very comfortable levels.

A strong cold front will approach the area later today and it’ll bring with it the chance of isolated thunderstorms during the afternoon and then another round of thunderstorms is possible from this evening into the overnight hours. Any thunderstorm later today or tonight can reach strong-to-severe levels with some heavy rainfall and powerful wind gusts. Ahead of the front, temperatures will soar today with afternoon highs well up in the 90’s and overall humidity levels will be quite uncomfortable; especially, compared to recent days.
It turns cooler on Thursday and Friday following the passage of the cold front, but also remains unsettled as the frontal system stalls out nearby. Looking ahead to the Labor Day weekend, the weather is likely to remain somewhat unsettled with the chance of showers and thunderstorms on Saturday and possibly again later Sunday as we’ll have to deal with a couple of cold frontal systems in the Mid-Atlantic region. A cooler and dry air mass will push into the northeastern states for the early part of next week.

High pressure will push into the region today providing us with quiet and warm weather, but the next cold front will bring us unsettled conditions by late tomorrow and tomorrow night. In fact, there is the chance for late day and nighttime showers and thunderstorms on Wednesday and some of the storms can be strong-to-severe. Temperatures will soar tomorrow ahead of the cold front reaching well up into the 90’s for afternoon highs, but then they’ll drop off noticeably for Thursday and Friday following the passage of the front. Looking ahead, Labor Day weekend is looking somewhat unsettled from this vantage point with the chance of additional showers and thunderstorms from time-to-time.

High pressure to our north dominated the weather scene around here for several days, but it loses control today as an upper-level trough builds into the Northeast US. As a result, there will be some cloudiness later today and the chance of afternoon and evening showers and thunderstorms...some of the storms can be strong. The next system of note will be a cold frontal system that crosses the region on Wednesday night likely accompanied by a round of showers and thunderstorms. It turns quite hot ahead of the front on Wednesday with highs well up in the 90’s and then much more comfortable air mass will follow for the late week.

High pressure to our north will remain in control of the weather as we end the work week and then slide off the east coast on Saturday. This repositioning of the high will open the door for seasonably warm air to push northeastward into the Mid-Atlantic region; however, overall humidity levels should remain moderate. The threat of rain will remain minimal around here during the next couple of days, but an upper-level low could increase the chances during the early part of next week.

High pressure to our north will remain in control of the weather for the next couple of days and continue to anchor a very comfortable air mass for this time of year. The high pressure system shifts offshore by early this weekend and this repositioning will open the door for warmer air to move into the area from the southern states, but no sustained extreme heat is in sight. The chances for rain should be minimal around here for the next few days.
One final note, this cool shot we’re enjoying has been pretty impressive for August. The low temperature on Wednesday at Dulles Airport (IAD) was 50 degrees…the lowest temperature there for the entire month of August since 1998.

High pressure to our north will remain in control of the weather in the Mid-Atlantic region for the next few days. The air mass in place is cooler-than-normal for this time of year and quite dry as well with comfortable humidity levels. The high shifts offshore by the weekend and this repositioning will open the door for warmer air to move into the area from the southern states. There continues to be, however, no sustained extreme heat in sight.

A cold front crossed the region late yesterday and its passage has ushered into the Mid-Atlantic region a much more comfortable air mass that’ll feature daytime highs in the 70’s during the next few days and overnight lows in the low-to-mid 50’s. This early taste of fall will be sponsored by Canadian-born strong high pressure that will be stationed over the northeastern part of the nation during the remainder of the work week.

A taste of fall is coming to the Mid-Atlantic region for the Tuesday, Wednesday, and Thursday time period following the passage of a cold front later today. That frontal system will produce scattered showers and thunderstorms this afternoon and evening and some of the storms can be on the strong side. Temperatures for the next few days should peak in the 70’s for afternoon highs all along the DC-to-Philly-to-NYC corridor which is well below-normal for this time of year. Temperatures in the overnight hours will bottom in the lower 50’s in much of the I-95 corridor – coolest so far this season – and some spots could bottom out in the upper 40’s well to the northwest of the big cities.
Elsewhere, Ernesto has intensified slightly during the morning hours over the North Atlantic with latest observations showing 90 mph maximum sustained winds. This classifies Ernesto as a strong category 1 hurricane which is somewhat unusual in that it weakened to tropical storm status on Sunday after passing by the island of Bermuda. Ernesto will rush past Newfoundland later tonight and then it can very well impact Ireland/United Kingdom later in the week as an extratropical storm.

A cold front crosses the region later today and can bring with it more in the way of scattered shower and thunderstorm activity. Some of the afternoon and evening storms can be strong, but much of the time today will be rain-free. Following the passage of the cold front, a cooler and crisp air mass arrives for Tuesday, Wednesday, and Thursday bringing a touch of fall to the area. Daytime highs during this stretch will be generally confined to the 70’s - well below-normal for this time of year - and overnight lows well down in the 50’s.
