Discussion

High pressure has pushed off the Northeast coastline and this has allowed for the return of high humidity air into the I-95 corridor. While there can be scattered showers and thunderstorms later today and early tonight in the DC metro region, a more widespread threat comes later tomorrow with the approach of the next strong cool frontal system. Any thunderstorm that forms between this afternoon and tomorrow evening in the I-95 corridor can contain some heavy rainfall. Once that next cool front clears the east coast early on Sunday, much cooler air will push into the area and it’ll stay cooler-than-normal on Monday, Tuesday and Wednesday. Showers are possible on Monday and Tuesday from a coastal low pressure area that will likely form over the weekend.

Discussion

After a warm and relatively moderately humid day today, high pressure will push off the Northeast coastline early Friday and this will usher in a return to higher humidity air for tomorrow afternoon and Saturday. While there can be an scattered showers and thunderstorms later today and again on Friday afternoon/evening, a more widespread threat comes on Saturday with the approach of the next cool frontal system. Once that next cool front clears the east coast on Sunday, cooler and drier air will push into the area and it’ll stay cooler-than-normal on Monday and Tuesday as well.

Discussion

A weak cool front passed through the region last night and it has ushered in a less humid air mass for the Mid-Atlantic region. High pressure builds back into the region today and we’ll have some sunshine both today and tomorrow with warm temperatures and fairly comfortable humidity levels. The humidity will build on Friday and there can be a shower or thunderstorm during the afternoon hours. On Saturday, the next cool front will approach and bring us a better chance for showers and thunderstorms during the late afternoon and evening hours. Much cooler and drier air will push into the region on Sunday and it'll remain cooler-than-normal on Monday and Tuesday as well.

Wednesday

Mostly sunny skies, warm, less humid, upper 80’s

Wednesday Night

Partly cloudy, mild, some fog possible late, upper 60’s

Thursday

Mostly sunny, quite warm, slight chance for a shower or thunderstorm, upper 80’s

Friday

Mostly sunny, very warm, more humid, near 90

Saturday

Partly sunny, quite warm and humid, chance for showers and thunderstorms, near 90

Sunday

Partly sunny, noticeably cooler, near 80

Discussion

The month of August ended with below normal temperatures in much of the Mid-Atlantic region which continued the trend begun in July; however, the first week of September will generally feature warmer-than-normal conditions. In fact, today could turn out to be the warmest day of the week with high temperatures this afternoon likely surpassing the 90 degree mark in most DC metro locations. There is relief on the way however. A weak cool front will pass through the area tonight and the result will be a pretty decent chance for early evening showers and thunderstorms. High pressure will build back into the area for Wednesday and Thursday providing us with warm temperatures and noticeably lower humidity levels. The heat and humidity will build up again on Friday and then, as another cool front approaches by the early weekend, the threat for showers and thunderstorms will increase for Friday night and Saturday. Once that next cool front passes through, noticeably cooler conditions will take hold in the Mid-Atlantic region on Sunday and Monday.

Discussion

Very nice weather conditions will continue in the region for another day as we close out the work week, but then as high pressure pushes off the east coast this weekend, changes will come to our air mass with increasing heat and humidity. By Sunday afternoon, high temperatures around here should flirt with the 90 degree mark and there will be an increased shot at showers and thunderstorms although most of the day will be rain-free. The shower and thunderstorm threat will continue on Monday and Tuesday in the Mid-Atlantic region, but most of those days should be rain-free as well.

At the nearby Atlantic beaches, the high waves and rip currents of recent days should subside this weekend as the remains of Hurricane Cristobal continue to race away into the North Atlantic. In fact, it may one of those rare occasions in which there are no tropical storms to talk about in the Atlantic Basin during the normally active period around Labor Day - and perhaps no tropical cyclones anywhere across the globe.

Discussion

A cool front moved through the region last and the result will be a much more comfortable air mass for today and Friday with slightly below normal temperatures and low humidity levels for this time of year. High pressure will be in charge through tomorrow, but then will slide off the east coast and this movement will allow for the return of much warmer and more humid air as the weekend progresses with an increasing shot at showers and thunderstorms. That threat for showers and thunderstorms will arrive on Sunday in much of the Mid-Atlantic region and continue on Monday and Tuesday as well. At the nearby Atlantic Ocean beaches, there will be high waves and possible rip currents today and on Friday as a result of the effects of Hurricane Cristobal which is racing away from the coastline towards the open North Atlantic. The high waves and rip current threat should subside this weekend.

7:00 AM | Very warm and humid today, but more comfortable air returns on Thursday and Friday

6-Day Forecast

Today

Thursday Night

Mostly clear, cool, low 60’s

Friday

Mostly sunny, still pleasant, low 80’s

Saturday

Partly-to-mostly sunny, warmer and more humid, chance for showers and thunderstorms at night, mid-to-upper 80’s

Sunday

Partly sunny, hot, humid, chance for showers and thunderstorms, near 90

Monday

Mostly cloudy, not as warm, humid, still the chance for showers and thunderstorms, mid-to-upper 80’s

Discussion

High pressure will push off the coast today and a weak cool front will approach from the west. Heat and humidity will build up noticeably ahead of the front throughout the Mid-Atlantic region and there can be a widely scattered late day or early evening shower or thunderstorm, but no significant rainfall is expected along the I-95 corridor and it could actually remain completely rain-free during this frontal passage. Another refreshing air mass will push into the region for Thursday and Friday, but then the humidity will climb this weekend as this next high pressure system moves off the coast and there will be an increasing chance for showers and thunderstorms as we progress through the holiday weekend.

Sunday

Discussion

High pressure will stay in control of our weather today and provide us with continued comfortable temperatures and humidity levels for late August. A weak cool front will cross the region tomorrow night and it’ll become warmer and more humid ahead of the frontal system on Wednesday. That front could spark a widely scattered shower or thunderstorm late tomorrow or early tomorrow night and then another refreshing air mass will push into the Mid-Atlantic for Thursday and Friday anchored by new high pressure. Once that next high pressure system pushes off the east coast at the end of the week, more humid air will return to the region and the threat for showers and thunderstorms will increase as the holiday weekend progresses. Elsewhere, Cristobal has reached weak hurricane status (category 1), but it will remain well off the east coast and head towards the open Atlantic later this week. Another tropical disturbance has formed in the eastern Atlantic and this system - as well as the entire Gulf of Mexico region - will have to be closely monitored during the next several days as atmospheric conditions will be increasingly favorable for tropical storm development.

Discussion

High pressure now sitting over the Northeast US will be the main player on the weather scene during the next couple of days as it will remain rather stationary. As a result, there will be plenty of sunshine through tomorrow with relatively comfortable temperatures and humidity levels. By Wednesday, however, humidity and warmth will increase ahead of a cool frontal system as the high slides off the northeast coastline promoting a southwesterly flow of air. That front could spark a shower or thunderstorm Wednesday night before yet another refreshing air mass returns to the Mid-Atlantic region for the latter part of the week. Meanwhile, Tropical Storm Cristobal formed yesterday near the Bahama Islands and all indications are that it will stay east of the US coastline this week before it turns away to the northeast. Cristobal certainly can reach hurricane status over the next couple of days as it meanders off the east coast and it will continue to be closely monitored.

Discussion

Unsettled weather will continue into tomorrow in the DC metro region with scattered showers and thunderstorms possible as additional upstream moisture rides along a frontal boundary zone. Cooler weather is in store for the weekend as strong Canadian high pressure will build southward into the area. Once this high takes control of the weather pattern, a persistent low-level flow of air will develop from the east-to-northeast. Temperatures will generally hold in the 70’s for highs this weekend and into the early part of next – well below normal for this time of year.
