&& .NEAR TERM /UNTIL 6 AM THIS MORNING/... Sfc hi pres will continue to build into the region from the NW overnight. Other than SCT-BKN CI...mainly central/S...SKC w/ NNW winds continuing to wane (lastly at the coast). Lows will range from the m-u20s N and W...to around 40F in far SE VA-NE NC. && .SHORT TERM /6 AM THIS MORNING THROUGH SATURDAY/... Going with a blend of the 12Z GFS and 12Z ECMWF for Thu thru Sat. A couple areas of high pressure will slide into or remain over the region Thu thru Fri, while low pressure will track fm the Gulf of Mexico NE to off the SE coast. Low pressure will then linger off the SE coast then Mid Atlc coast Fri evening thru Sat morning. Mostly clear and cool Thu/Thu night and Fri. With fairly limited/shallow mixing both days and very dry conditions (dew pts in the 20s and 30s), went on the cold side of guidance both for highs Thu/Fri, and for lows Thu night/Fri morning. This yields highs Thanksgiving Day mainly in the upper 40s to lower 50s. Lows Thu night in the upper 20s to mid 30s, and highs on Fri in the mid to upper 50s. Next upper trough moves into/thru the Great Lakes Fri night/Sat. Still looks like bulk of moisture from low pressure off the SE and Mid Atlc coasts stays over the gulf stream, as it lifts NNE. Some increase in clouds Fri night/Sat, but will have just a 20% PoP over extrm SE VA and NE NC, dry elsewhere. Cold front then crosses the area late Sat into Sat night, with just a slgt chc of showers at most. Milder Fri night with lows ranging fm the mid 30s inland to the lower to mid 40s in the ern third of the region. Highs on Sat in the upper 50s to lower 60s. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... Dry weather and increasing temps on tap for the long term period. Sfc high pressure builds in from the west early next week as an upper-level trough pulls offshore, leading to mostly sunny/clear skies Sun and Mon with high temps averaging in the low/mid 50s. Warmer then for Tue and Wed as the high slides offshore allowing for S/SW flow over the Mid Atlc...highs in the upper 50s to mid 60s. && .AVIATION /06Z THURSDAY THROUGH MONDAY/... SCT-BKN CI into Thu...otherwise VFR conditions expected through the 00Z/23 TAF period as sfc hi pres builds in from the west. NNW winds mainly blo 15 kt. Sfc hi pres will maintain VFR conditions into Sat. && .MARINE...

High pressure has begun to build into the region from the west early this morning which is allowing winds to gradually diminish. As of 1 am, the SCA for the lower James River has been allowed to expire. SCAs for the Currituck Sound and much of the Chesapeake Bay should be able to come down by 4 am, with the remaining SCAs for the mouth of the Bay and coastal waters set to expire by 7 am and 10 am respectively as seas subside. Latest NWPS wave guidance is a bit slower to brings seas down until this afternoon so an extension in time may be needed later this morning. With high pressure over the waters, sub-SCA conditions are expected into Friday. The next cold front crosses the region Saturday night bringing the potential for gusty NW winds/SCA conditions for Sunday.
