&& .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... As of 145 PM EST Thursday... Key Messages: 1: Showers Wednesday in the mountains 2: Cooler temperatures again Thursday morning A cold front will push high pressure off the east coast during the overnight hours Tuesday night into Wednesday. The front will graze the area, bringing some showers primarily to our western mountain areas. Those east of the Blue Ridge will be unlikely to see anything more than a passing drizzle. As the cold front exits on Wednesday night, more high pressure will fill in behind it from the north. This will bring a cool dry airmass into the Mid-Atlantic. Thursday as a result will be below normal in temperatures, with the potential for frost in the mountains. Thursday also begins the growing season for that region, so if the conditions warrant, which it appears they do, frost advisories could be on tap Thursday morning. Wednesday will feel warm with temps in the 60s and 70s before a much cooler night with encroaching cool high pressure from the north. Overnight lows will drop into the mid 30s/low 40s. With clear skies again on Thursday though, there will be a hefty diurnal swing back to the upper 60s. && .LONG TERM /FRIDAY THROUGH MONDAY/... As of 145 PM EDT Monday... Key Messages: 1) Confidence is high for a warming trend during the weekend. 2) Chances of showers and thunderstorms will gradually increase. High pressure will wedge against the eastern slopes of the Blue Ridge on Friday, and an easterly flow should keep temperatures near or slightly below normal. A warm front will nudge northward around the western periphery of the wedge during Friday afternoon into Saturday, which could bring a chance of showers and thunderstorms for the mountains. As high pressure drifts offshore by Sunday, the wedge will weaken as the flow swings to the southwest. Increasing warm air advection and an approaching upper level ridge will push high temperatures above normal on Sunday afternoon. Meanwhile, a low pressure system intensifying in the Plains could combine with the increasing warmth and moisture to promote higher chances of showers and thunderstorms west of the Blue Ridge as the weekend concludes. && .AVIATION /00Z TUESDAY THROUGH SATURDAY/...

As of 725 PM EDT Monday... VFR conditions are expected across the entire area for the valid 24 hour TAF period. Generally light and variable winds tonight, becoming southwest Tuesday morning. Extended Aviation Outlook... Another cold front will arrive during Tuesday night into Wednesday to bring the next potential for MVFR ceilings and rain showers in the mountains. Thursday looks dry and supporting of VFR. A warm front approaches Friday although VFR conditions remain, but could start to see sub-VFR toward LWB/BLF late Friday into Friday night.
