High pressure will push offshore today and a frontal boundary to our south will begin to push northward on Friday. As a result, our weather will become more unsettled as we close out the work week and it’ll stay unsettled this weekend as well with a daily shot at showers and thunderstorms. Another frontal system will approach the region on Monday and this will continue the unsettled weather pattern for the early part of next week. No excessive heat is likely over the next several days and high temperatures should hold in the 80’s going well into next week.

High pressure will continue to control our weather for the next couple of days and conditions will remain quite pleasant for August with comfortable temperatures and low humidity levels. The overall pattern, however, will become more unsettled as we approach the weekend as an upper-level trough digs towards the east coast. In fact, this could result in some more rainfall for the I-95 corridor on Friday, Saturday, Sunday and Monday as multiple low pressure systems cross the region.

A week in August without one 90 degree day – sure looks likely this week in the DC, Philly and NYC corridor. A cold front came through the region last night and clouds this morning should give way to some sunshine. High temperatures for much of the week will be closer to the 80 degree mark than the 90 degree mark which is below normal for this time of year.

Low pressure will track along a frontal system today and generate occasional rain and possible thunderstorms as we start off the new work week. Some of the rain will fall heavily at times with more than two inches in some areas and the combination of clouds and the rainfall will help to keep temperatures confined to the 70’s for highs. In fact, there will likely be no uncomfortable excessive heat this entire week as another refreshing high pressure system takes control at mid-week.

A cold front will approach the area late today and then slide through early on Saturday. As a result, there will likely be some shower and thunderstorm activity during the afternoon and nighttime hours and perhaps even some residual activity early tomorrow on an isolated basis. After the frontal passage, a more comfortable air mass will push into the Mid-Atlantic region for later Saturday, Sunday and Monday and we’ll experience lower humidity and rather pleasant temperatures for early August. Another front should cross the region early next week and it could result in another round of showers and thunderstorms late Sunday night and on Monday.

The weather will remain somewhat unsettled over the next couple of days in the I-95 corridor as moist air interacts with the approach of another frontal system to keep alive the threat for PM showers and thunderstorms. This front will ultimately slide through the area early in the weekend and its passage will usher in quite comfortable air for the early part of August. In fact, Sunday promises to be as spectacular as last Sunday with plenty of sunshine, low humidity, and comfortable temperatures topping out in the lower 80’s. Another front is likely to bring us a round of showers and thunderstorms on Monday.

High pressure has shifted off the coast and this has opened the door for a southerly flow of air to bring in more humid air from the southern states. As a result, the threat for showers and storms will return today and any storm that forms can produce heavy rainfall and frequent lightning. The threat for showers and storms will continue during the next couple of days as a frontal system approaches the region. More comfortable air will arrive this weekend and temperatures may hold in the lower 80's for highs on both days. In fact, the prospects for another spectacular Sunday are quite high with plenty of sunshine anticipated along with low humidity and comfortable temperatures.

Humidity levels will rise a bit today as high pressure begins a shift to off the Northeast US coastline. Higher humidity levels and an approaching frontal system will make it more unsettled around here for the second half of the work week. As a result, the chance for showers and thunderstorms will return on a daily basis, but no widespread heavy rain event is likely in the near term. Also, no excessive heat is likely as we progress through the first few days of August.

The new work week gets off to a pretty nice start today with comfortable humidity levels for the end of July and plenty of sunshine. High pressure has taken control of our weather following the departure of the weekend storm which pounded the region from DC-to-Atlantic City, NJ, but left the NYC metro region virtually unscathed. Humidity will become more noticeable on Tuesday and then the second half of the week will become more unsettled with the threat for scattered showers and thunderstorms

Our late week heavy rain event is now underway in and around the DC metro region with torrential rain already falling in some areas. Low pressure is now forming along a stalled out frontal boundary zone and it will intensify as it heads towards the Mid-Atlantic coastline over the next 12 hours. The rain will gradually spread from southwest-to-northeast over the next few hours likely reaching the Philly metro region by early tonight. The heaviest rainfall amounts during this unfolding storm will likely be in the DC-Delmarva Peninsula-southern NJ corridor where perhaps 4-7 inches can accumulate in spots by tomorrow morning. The New York City metro region will be largely spared of the heavy rainfall and there will be a sharp drop off in the total rainfall amounts from south-to-north between southern and central Pennsylvania.
