A frontal system has stalled out to our south and it will act as a conduit for moisture to ride along over the next 36 hours and the result will be a soaking rainfall for the NYC metro region. There will be multiple rounds of rain into late Friday with thunderstorms also mixed into the picture and some spots may end up with more than two inches of rainfall by tomorrow night. Temperatures today will be held down significantly by clouds and rainfall, but this same front will push northward tomorrow as a warm front and we’ll turn noticeably warmer on Friday as we close out the work week. A cold front, however, will arrive tomorrow night and it’ll usher in a nice air mass for July for the upcoming weekend with low humidity.

A frontal boundary has stalled out nearby and this system will contribute to a soaking rain event around here from later tomorrow into Friday. Occasional showers and thunderstorms are likely late tomorrow, tomorrow night and Friday and some of the rain can come down hard at times. A nice air mass for this time of year will arrive just in time for the upcoming weekend.

A frontal system will approach the region later today and it could spark a shower or thunderstorm in the area. High pressure builds in behind the frontal passage on Tuesday and then the high will push offshore at midweek. The front that pushes through by tomorrow as a cool front will then return northward later this week as a warm front.

High pressure has shifted to a location off the east coast and this re-positioning will allow for very warm and humid air to flow into the Mid-Atlantic region from the Deep South. As a result, high temperatures for the next few days are likely to climb to within a few degrees of the 90 degree mark to go along with more noticeable humidity levels. As far as precipitation is concerned, while there can be an isolated shower or thunderstorm today and tonight and again early next week, the best chance for showers and thunderstorms through next Tuesday is likely to come later tomorrow and tomorrow night as a frontal system approaches the region and some of these storms can be strong-to-severe.

It’ll turn breezy and noticeably warmer today as high pressure shifts off the coast and our low-level winds become southwesterly. It’ll be very warm and humid on Friday, Saturday and Sunday and there can be some shower and thunderstorm activity with the best chance coming late Saturday/Saturday night. One final note, NASA succeeded early this morning in the launch of a sounding rocket at the Wallops Island, Virginia facility after several prior postponements due to clouds, etc.

Comfortable conditions will continue for another day in the Mid-Atlantic region, but it'll turn much warmer and more humid on Thursday and then hot, humid weather looks rather likely for much of the upcoming weekend. In terms of rainfall, an isolated shower or thunderstorm will be possible on Friday and showers and thunderstorms threaten later Saturday into Sunday as a frontal system approaches the area. One final note, NASA/Wallops will attempt the “artificial cloud” rocket launch very early tomorrow morning (between 4:25 and 4:48 AM).

High pressure continues to control our weather in the Mid-Atlantic region and temperatures should remain rather comfortable for late June through tomorrow. Later in the week, a return of hot and humid weather will take place and with it will come an increasing chance for showers and thunderstorms. It looks like once that return to somewhat unsettled weather returns by the end of the week it’ll stick around right into the early part of next week.

Following the passage of the remains of Tropical Storm Cindy, a refreshing air mass for late June has pushed across the Great Lakes and into the Mid-Atlantic region. Temperatures for the next few days will be rather comfortable around here for this time of year and downright cool for the Great Lakes, Upper Midwest and Northern Plains. It’ll turn very warm again towards the end of the week and the summer-like humidity will return. The weather pattern will likely become unsettled again at the end of the week and that unsettled weather looks like it will continue through the weekend and into the early part of next week. A stalled out frontal boundary zone it likely to bring us a daily chance of showers and thunderstorms during this upcoming unsettled stretch. One final note, in the "deja vu" department, NASA/Wallops once again postponed the artificial cloud rocket launch which was scheduled for Saturday night - no new date has been set.

The remains of Tropical Storm Cindy are resulting in heavy rainfall today across portions of the Mississippi and Tennessee Valley and this area of moisture is headed to the Mid-Atlantic region. The tropical moisture associated with Tropical Depression Cindy should arrive in our area late tonight and early Saturday and some heavy rainfall is likely and there can be strong-to-severe thunderstorms mixed in. In addition to the tropical storm-related rainfall expected late tonight and early Saturday, an approaching upper-level wave of energy will destabilize this afternoon and the result will likely be scattered showers and thunderstorms into the early evening and some of these storms can be on the strong-to-severe side. Bottom line, it looks like an interesting period from this afternoon to about mid-day on Saturday in the DC-to-Philly-to-NYC corridor. The good news is that most of the rainfall will pull out of here by tomorrow afternoon and the weekend should close out on a pretty nice note from later tomorrow through Sunday.

The remains of Tropical Storm Cindy will interact with a slow-moving frontal system and produce some heavy rainfall around here late tonight and early Saturday. Before that tropical moisture arrives, there will likely be an occasional shower and thunderstorm today and early tonight, any of which can produce some heavy rainfall. Most of the rainfall should move out of here by tomorrow afternoon and the weekend will close out rather nicely late Saturday and Sunday. One final note, NASA/Wallops will try again early tomorrow night with its sounding rocket launch that should produce colorful artificial clouds visible in DC (look southeast), Philly and NYC (look south-to-southeast).
