DAYS 1-5 (AUGUST 16-20)
High pressure overhead now will shift offshore through Tuesday and a warm front will approach the region later Tuesday. During the next two days there will be some high and mid level clouds around, though limited to mostly this morning during today before becoming more widespread Tuesday. The warm front will cross the region Tuesday night and introduce higher humidity for Wednesday through Friday. In addition, a couple disturbances including the remains of what was once Tropical Storm Fred will be pushed into our region, increasing the chance of shower activity, though the chance will not be that great and will be mostly over interior areas Wednesday before peaking on Thursday and continuing into Friday before diminishing later Friday.

DAYS 6-10 (AUGUST 21-25)
There is a little uncertainty in the forecast for the August 21-22 weekend. Expecting the main plume of tropical moisture to have shifted offshore, reducing the chance of showers from that, but a weak upper low over the Great Lakes trying to move into New England with additional shower opportunities, while high pressure to the north may do its part to send somewhat drier air into the region. Putting this together, leaving a slight chance of showers in, favoring Saturday, warmest and highest humidity day being Saturday with slightly cooler and less humid air arriving Sunday. Fine-tuning is going to be needed for that forecast as we go along this week. Based on the anticipated weekend scenario and the guidance that shows it best, will go for dry weather August 23 then slightly higher humidity and a return to the chance of some shower activity August 24 with dry air again attempting to move back into the region for the end of the period.
DAYS 11-15 (AUGUST 26-30)
The guidance trend says the East Coast has a little less to worry about regarding potential tropical systems, but always keeping an eye out there. High pressure should be the dominant player with mostly rain-free weather and near to above normal temperatures.
