There is a chance for some significant rainfall later this week in the Mid-Atlantic as a cold front inches its way across the region in the late Wednesday to late Thursday time period. The slow moving surface cold frontal system will have support aloft with a strong disturbance and will have lots of low-level moisture to work with as a broad southerly flow of air develops just ahead of it. The front will be followed by cooler-than-normal air in the eastern states for the late week and upcoming weekend.

The cold front that generated yesterday’s showers and thunderstorms will tend to linger near the east coast today as an upper-level trough slides slowly across the region. As a result, there can be some lingering clouds today and perhaps a shower or thunderstorm. Clearing skies tonight will result in cooler conditions and the next couple of days will be quite comfortable for this time of year and there should be plenty of sunshine as well. The overall weather pattern remains pretty nice as we get to the early part of next week with temperatures climbing a bit compared to the early weekend levels.

The weather has certainly been active in the Mid-Atlantic/Northeast US in recent weeks and there is yet another threat for severe thunderstorm activity later today and tonight. A strong cold front will drop southeastward later today from the Great Lakes and into the region and it will be supported by an impressive wave of energy in the upper atmosphere. As a result, there is the chance for downpours later today into tonight and any severe storm can produce hail and perhaps even isolated tornadoes. Give the already well-saturated grounds, any heavy rainfall can result in localized flash flooding conditions. The passage of the strong cold front will usher in a very comfortable air mass for the region to close out the work week and begin the upcoming weekend.

A cold front will arrive later today and present us with the best chance of showers and thunderstorms this week. In fact, some of the late day and evening storms in the Mid-Atlantic region can be severe with brief heavy downpours possible and even isolated tornadoes. Given the well-saturated grounds, any heavy rainfall later today can result in localized flash flooding. Following the passage of the front, the latter part of the week will feature comfortable weather conditions to go along with plenty of sunshine. The nice weather pattern will continue into the upcoming weekend and temperatures will warm a bit, but remain pretty comfortable for this time of year.

In the wake of yesterday's high impact weather event, a stretch of nice weather is in store for the Mid-Atlantic region. Drier and cool air for this time of year has pushed into the Mid-Atlantic region following the movement of “Ida” to the New England coastline. High pressure will build into the area by later tonight and this system will result in nice weather around here right through the upcoming weekend with temperatures staying quite comfortable for early September.

A significant rain event continues at this time across much of the Mid-Atlantic region associated with the remains of Ida. Flooding has already occurred in some areas as a result of heavy rainfall, strong thunderstorms and already well-saturated grounds. The threat of tornadoes will increase markedly later in the day generally in areas along and to the southeast of the DC-to-Philly-to-Atlantic City corridor. Ida is still classified as a tropical depression and it will likely strengthen some later today as it encounters an upper-level jet streak that is located over the northeastern states.
