Key message 1: Dry weather with seasonable temperatures expected this weekend, then slightly warmer with continued dry conditions through late next week. A strong nor`easter will continue to develop over the Mid-Atlantic offshore waters thru the weekend, drifting north toward New England. The forecast area will be on the dry N/NWLY flow side of the storm`s circulation, which will make for pleasant weather conditions across the area. Cool, crisp low temps will continue tonight and again Saturday night, while highs rebound to near normal under sunny skies. Dry conditions continue thru most of next week, as an upper ridge slowly builds in behind the departing nor`easter, and sfc high pressure remains over the Southeast. Temps warm to slightly above normal, but with a slow, gradual increase in sfc dewpts/humidity. With no significant moisture return until Friday at the earliest...and more likely over the next weekend...the forecast remains dry thru Wednesday. The National Blend of Models shows slight chance to low-end chance PoPs start to return Thursday thru Friday, mainly in the mountains. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
