A cold front will gradually sag to the south of here during the next 24 hours or so leading to improving weather conditions on Friday and a comfortable day on Saturday with moderate humidity levels. The second half of the weekend starts off rather comfortable; however, the low-level wind pattern will change allowing for more moisture to move into the Mid-Atlantic region and there will be an increasing chance of showers and thunderstorms.

Perseid meteor shower tonight…
Somewhat unsettled conditions here at mid-week with a frontal system hanging around the Mid-Atlantic region. This cold front will attract a couple of waves of energy during the next couple of days raising the possibility of scattered showers and thunderstorms. The front should clear the region by Thursday night leading to the push of drier and cooler air mass into the Mid-Atlantic for the end of the week and upcoming weekend.

The next couple of days will continue to feature somewhat unsettled conditions around here with the chance for showers and thunderstorms; however, a better chance of rain will take place just to our south across the southern Mid-Atlantic. There is some relief on the way by the end of the week as a cool frontal should slide to the south of here allowing for the arrival of a slightly cooler and less humid air mass as we enter the weekend.

The next few days will continue to feature rather warm and humid conditions with a daily shot of showers and thunderstorms, but relief is on the way by the weekend. An upper-level wave of energy passes through the area later today and tonight enhancing the chance of shower/thunderstorm activity and any storm that forms can be strong and brief downpours are a possibility. Additional waves of energy will ride along a slow-moving frontal boundary zone on Tuesday and Wednesday keeping the chance alive for showers and thunderstorms. At the end of the week, the front should clear the area and cooler and drier air should push into the Mid-Atlantic region with more comfortable weather conditions likely lasting through the weekend.

With high pressure parked over the western Atlantic Ocean, tropical air will continuously flow northward in coming days all the way from southern Florida to northern New England. Humidity will remain at uncomfortably high levels right through the upcoming weekend and there will be a daily threat of showers and thunderstorms with the greatest chance occurring during the afternoon and evening hours…any storm can produce heavy rainfall.

On the heels of a warm frontal passage, humid air has pushed northeastward into the Mid-Atlantic region here at mid-week and it’ll stick around for a prolonged period of time. A strong “Bermuda-high” pressure system centered over the western Atlantic Ocean will continuously pump humid and quite warm air northward during the next several days from the Gulf region to New England. There will be occasional showers today, tonight and tomorrow and thunderstorms are possible primarily during the PM hours…any rain can fall heavily and produce localized flash flooding conditions.

A weakening upper-level trough in the eastern US will give way to an intensifying ridge over the western Atlantic leading to a rather typical “Bermuda-high” summertime weather pattern. After a warm front pushes northward through the region later today, the stage will be set for warm and humid conditions and southwesterly flow on the backside of the Atlantic ridge will assure it’ll be a sustained period of “Bermuda-high” type weather in the eastern states. The chance for showers and thunderstorms will be relatively low on Tuesday, but will climb to higher levels from tomorrow into the upcoming weekend.

It is rather warm and humid today in the DC-to-Philly-to-NYC corridor and it looks like we better get used to these conditions as a “Bermuda-high” weather pattern is setting up for the eastern states. An upper-level trough of low pressure over the eastern US here at the beginning of the week will dissipate shortly and strong ridging will form over the western Atlantic by mid-week. As such, a broad southwesterly flow of air will develop along the Atlantic Seaboard and likely persist for several days bringing warm and humid conditions to the I-95 corridor and moisture levels will be high enough to produce a daily shot of showers and thunderstorms.

An upper-level trough has moved into the eastern states and it will lead to an unsettled start to the new work week with an associated frontal system pushing through the region tonight. As a result, there can be additional occasional showers and thunderstorms through tonight and any rain that falls can come down heavily at times. A warm front will then push northward through the area later tomorrow setting the stage for the remainder of the week to remain quite warm and humid and there will be a daily shot at showers and thunderstorms.
