A cold front will clear the region this morning and its passage will pave the way for a stretch of cool and dry weather. Sunshine will return in full force later today, but temperatures will be some 5-10 degrees cooler than yesterday and the breeze may pick up a bit from a northwesterly direction. The next few late nights could feature overnight low temperature readings in the upper 40’s in some of the normally colder suburban locations. In terms of rainfall, high pressure will remain in control during the next few days and virtually assure dry conditions in the Mid-Atlantic region until late Sunday or Sunday night.

A significant rain event is now getting underway in the Mid-Atlantic region and it will continue into early Friday as a cold front inches its way across the area.
