A frontal boundary zone is hanging nearby this morning and there will be occasional showers and possibly an isolated thunderstorm. A disturbance form the Tennessee Valley will push northeastward into the Mid-Atlantic region this weekend and the result will be additional showers and possible thunderstorms…some of the rain can be heavy. Some improvement is likely later Sunday and the new work week should start with plenty of sunshine on Monday and Tuesday and moderately warm conditions.

A weak cold front will approach the region later today and it can produce showers around here with a possible late day or evening thunderstorm. The front should clear the coast on Friday morning paving the way for a comfortably warm end to the shortened work week and some clearing skies in the afternoon with temperatures reaching the lower 80’s. Another disturbance will arrive this weekend and it can cause showers and thunderstorms in the Mid-Atlantic region from Saturday into Sunday.

High pressure will continue to generate tranquil and warm conditions around here today, but a cold front will head in this direction on Thursday. This next front will raise the chance of showers and thunderstorms later tomorrow and early tomorrow night, but it doesn’t look as widespread of an event as we have experienced in recent days. High pressure should follow the frontal passage for the end of the week with rain-free and warm conditions likely on Friday, but another disturbance can bring us showers and thunderstorms during the upcoming weekend.

After a bit of a break in the high heat on Wednesday, southwesterly flow will push much warmer air back into the region and temperatures should climb to the low-to-mid 90’s. As has been the case in recent days, showers and thunderstorms are forming to our northwest and they’ll drop to the south and east for possible impact during the afternoon and evening hours. Any storm that forms later today can be on the strong-to-severe side with heavy downpours and possible damaging wind gusts. A frontal boundary zone will remain close enough on Friday to keep it unsettled around here with a continuing chance of showers and thunderstorms. A more comfortable air mass should drop southward into the region for part of the Labor Day weekend featuring at or slightly below normal cooler temperatures and lowering humidity values.
One final note…anyone planning to travel to Penn State for their first game on Saturday (@3:30pm) can expect to see mainly sunny skies and high temperatures in the upper 70’s.

The peripheral region of an intense upper-level ridge can often be quite an active area for thunderstorms this time of year and this summer has been no exception. Specifically, the northeastern quadrant of an intense upper-level ridge where northwesterly flow dominates in the overall clockwise circulation around high pressure can often contain numerous bands of thunderstorms, complexes of thunderstorms and even long-lasting lines known as derechos. This “ring of fire” region in the outer peripheral of high pressure with northwesterly flow aloft has been repeatedly showing up this summer extending from the Great Lakes to the Mid-Atlantic and numerous severe weather outbreaks have been the result. A repeat performance is on the table during the next few days with Tuesday, Wednesday and Thursday likely to feature numerous bands of strong-to-severe thunderstorms that will potentially impact the DC-to-Philly-to-NYC corridor.

Looking ahead, the Labor Day weekend could be more comfortable following the passage of a cold front and high pressure to our north taking control.
