Strong high pressure that has controlled our weather during the past several days will lose influence today and we'll have a good chance for mid-day and afternoon showers and some of the rain can come down hard at times. The threat of rain will continue tonight and on Thursday ahead of a slow-moving cold frontal system and it’ll stay on the warm and humid side. High pressure builds into the area from the north on Friday and it’ll result in comfortable conditions around here on both Friday and Saturday. By Sunday, a warm front will arrive from the south and we’ll have a return of unsettled weather conditions to end the weekend.

After a spectacular stretch of nice weather that encompassed the long holiday weekend, high pressure will remain in control of our weather for one more day in the Mid-Atlantic region. After some early morning fog, skies will become mainly sunny and temperatures should climb well into the 80’s this afternoon after a fairly cool start to the day. The weather becomes more unsettled again on Wednesday and Thursday as a slow-moving cold front approaches the area with a renewed shot of showers and thunderstorms. High pressure returns at the end of the week with nice weather once again quite likely for Friday and Saturday before it turns unsettled again on Sunday. Meanwhile, the Rocky Mountain States are experiencing wild weather conditions with summer-like heat on Monday to accumulating snow today in many higher elevation areas from Wyoming to New Mexico and, in some cases, significant amounts.

A strong cold front has passed through the region and high pressure will expand eastward today into the Mid-Atlantic region from the Upper Midwest. As a result, we’ll experience a stretch of nice weather from today through Labor Day Monday of next week. The same high pressure system will push off the east coast early next week and a broad southwesterly flow of air will develop in the lower and middle parts of the atmosphere and we’ll become warmer and more humid by Tuesday and Wednesday.

A stretch of nice weather begins on Friday in the Mid-Atlantic region and continues through Monday, but there is a threat of severe weather before we get there. A strong cold front is crossing the Great Lakes region today and headed towards the Mid-Atlantic and its approach will enhance the chance for showers and thunderstorms in the 2-9 PM time period. Any storm that forms later today or early tonight can become severe with potentially damaging wind gusts and heavy rainfall…perhaps even a few isolated tornadoes. The good news is that all of this activity clears out by early tomorrow setting the stage for a stretch of nice weather from tomorrow through the Labor Day holiday.

A warm front lifted through the region on Wednesday and now attention turns to an incoming strong cold front to our northwest that will push through by early Friday. Today will turn out to be quite warm ahead of this frontal system and there is an enhanced chance of PM showers and thunderstorms. Any storm that forms later today or early tonight can be on the strong-to-severe side with damaging wind gusts and heavy rainfall. Following the frontal passage early tomorrow, high pressure will build into the Mid-Atlantic region and we’ll experience a stretch of nice weather from tomorrow into early next week.

The next 24-36 hours will be an active period in the Mid-Atlantic region with the threat for strong-to-severe thunderstorms both later today and again later tomorrow. A warm front lifted northward through the region earlier today and it has resulted in an increase in overall humidity levels as well as an increase temperatures now peaking in the low-to-middle 80’s. Another frontal boundary zone will approach the I-95 corridor region later in the day and this will set off some strong-to-severe thunderstorm activity…likely in the 4 to 10 PM time period. An even stronger front will approach from the northwest late tomorrow and this too is likely to generate some strong-to-severe thunderstorm activity in the Mid-Atlantic region. The good news is that all of this activity clears out early Friday - setting the stage for a stretch of nice weather from Friday into early next week.

A warm front is lifting through the region this morning and the afternoon will turn out to be warmer than recent days with the chance of late mid-to-afternoon showers and thunderstorms. The chance of showers and thunderstorms will continue tonight and on Thursday as well as a weak cold frontal system arrives. Any storm that forms from later today through tomorrow night can be on the strong-to-severe side with gusty winds and heavy rainfall. An even stronger front should push through the area by early Friday paving the way for a nice stretch of weather beginning on Friday and continuing into early next week.

Clouds will dominate the skies again today in the Mid-Atlantic region and there will be more shower activity to go along with the still rather comfortable temperature pattern. It’ll turn warmer and more humid on Wednesday following the passage of a warm front and the chance of showers and thunderstorms will return and that threat will continue on Thursday as well. A cold front is likely to push through at week’s end and is likely to set the stage for a nice Saturday and Sunday as high pressure builds into the area.

The comfortable temperatures that arrived in the Mid-Atlantic region on Sunday following the passage of a cold front will last for another couple of days; however, clouds will dominate the skies and there will be some shower activity today, tonight and on Tuesday and some of the rain can come down hard at times. It’ll turn warmer at mid-week and there will be the chance for some shower and thunderstorm activity, but a late week cold frontal passage could set the stage for a nice weekend.

The next 24-36 hours will be a very active period in the Mid-Atlantic region with the threat for severe thunderstorms from later this afternoon into tomorrow night and tropical downpours. There are even signs for a “bow echo” to form later today which could result in damaging wind gusts of > 60 mph (and possible power outages); especially, across eastern Pennsylvania and the southern and central parts of New Jersey. There is even the threat for isolated tornadoes later today in the I-95 corridor. Following all of this activity, a spectacular air mass for this time of year will ride in on stiff NW winds during the day Sunday and the very comfortable temperatures and humidity levels will stay around on Monday as well. Looking ahead, it’ll turn much more unsettled again around here on Tuesday and Wednesday with a renewed chance of showers and thunderstorms, and peaking even further down the road, there could be more tropical trouble to deal with in the eastern/southern states over the next week or two.
