7:00 AM | Very nice for today and Friday…increasing heat and humidity for the weekend and a shot at showers and thunderstorms

6-Day Forecast

Today

Sunny, very nice with noticeably lower humidity, a refreshing NW breeze, highs in the low 80’s

Tonight

Mostly clear and quite cool, lows by morning in the low-to-mid 50’s

Friday

Mostly sunny skies, still pleasant, light and variable wind, near 80

Friday Night

Partly cloudy, cool, upper 50’s

Saturday

Partly-to-mostly sunny, more humid and a bit warmer, low-to-mid 80’s

Sunday

More clouds than sun, very warm and humid, chance for showers and thunderstorms, upper 80’s

Monday

More clouds than sun, still warm and humid, chance for showers and thunderstorms, mid-to-upper 80’s

Tuesday

Partly sunny, warm, still the chance for showers and thunderstorms, mid-to-upper 80’s

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. Down at the shore, 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 | Today will be the warmest day of the work week, but refreshing air returns for Thursday/Friday

6-Day Forecast

Today

Mostly sunny, quite warm and humid, slight chance for a late day shower or thunderstorm, highs near 90 degrees

Tonight

Slight chance for an early evening shower or thunderstorm; otherwise, partly cloudy skies, turning a little cooler late, lows by morning in the lower 60’s

Thursday

Mostly sunny skies, quite nice with noticeably lower humidity, low 80's

Thursday Night

Mostly clear, cool, mid 50’s

Friday

Mostly sunny, still pleasant, near 80

Saturday

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

Sunday

Partly sunny, quite warm and humid, chance for showers and thunderstorms, upper 80’s

Monday

Mostly cloudy, not quite as warm, still the chance for showers and thunderstorms, low-to-mid 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.

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.

Tuesday

Mostly sunny skies, comfortably warm, moderate humidity, mid 80’s

Tuesday Night

Mostly clear, cool, low 60's

Wednesday

Mostly sunny, warmer and more humid, chance for a shower or thunderstorm at night, upper 80’s

Thursday

Partly sunny, pleasant, low 80’s

Friday

Mainly sunny, nice, near 80

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.
