&& .SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/... Mostly sunny Friday as dry and cool surface high pressure builds overhead, sliding offshore Friday night and Saturday. Not quite as mild Friday, with highs in the low to mid 50s beneath a decent subsidence inversion. Lows Friday night/early Sat morning in the mid 30s inland to the low/mid 40s coast. Milder in stronger return flow on Saturday. Compressional warming out ahead of next (stronger) cold front will drive maxima well into the 60s...to around 70 across SE VA/NE NC, with low to mid 60s across northern zones. Brief window for pops coincident with frontal passage Sat evening (west) into late Saturday night (east of I-95). Will carry likely PoPs (55-70%) most areas Sat night. Clouds will gradually increase through the day, remaining partly to mostly cloudy overnight. Lows Saturday night in the 40s to low 50s. Cold front pushes offshore on Sunday. After some lingering clouds east (morning shower possible over coastal areas), subsidence behind the front should result in a mostly sunny sky. Cooler again with highs in the 50s...to near 60 SE coast. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... High pressure is expected to build into the region Monday before moving offshore during the day on Tuesday. Cold air aloft and a northwest flow will lead to a chilly day on Monday with highs struggling to climb out of the upper 40s. Lows on Monday night will dip down into the lower 30s away from the coast and upper 30s to near 40 at the coast. Temperatures warm on Tuesday due to southerly flow on the backside of the high. Highs on Tuesday will range from the upper 50s to the lower 60s. A dry cold front is expected to drop into the region late Tuesday night. High pressure builds back into the region Wednesday through Thursday which will allow for continued cool but dry conditions. && .AVIATION /03Z FRIDAY THROUGH TUESDAY/... High pressure prevails over the region tonight and Friday bringing dry and VFR conditions. VFR conditions are expected through Saturday, before the next cold front approaches the region Saturday night. Sub-VFR cigs and rain showers are possible with the frontal passage Saturday night into Sunday morning. High pressure builds back into the region Sunday allowing for a return to VFR conditions. A gusty NW wind is possible behind the front on Sunday. High pressure gradually slides off the Southeast coast Monday and Tuesday. && .MARINE... Current low end gales (gusts to 35 kt out 10-20nm, ending by 12Z) / high end SCA`s in place tonight as a fairly significant CAA surge noted behind the cold frontal passage. Seas 5 to 6 feet. Winds / seas subside as high pressure builds into the area Friday and Friday night before moving offshore Saturday. Another round of SCA`s likely as strong cold front crosses the waters late Saturday. South winds will likely reach SCA levels Saturday afternoon and evening before shifting to the west then northwest Sunday. Potential for gale force gusts over the northern coastal waters once again. Winds diminish Monday and Tuesday as high pressure builds back into the area. && .AKQ WATCHES/WARNINGS/ADVISORIES... MD...None. NC...None. VA...None.
