As of 737 PM EDT Tuesday...Overall forecast for the overnight hours remains in good shape with the idea that we`ll see some increasing low/mid clouds shifting in associated with a shortwave trough passing to our north. Made some adjustments to sky cover and temps based on current trends, but in general the previous forecast remains intact. Previous Discussion...Quiet conditions will continue over the next 36 hours and beyond as strong high pressure bridges across the northeastern states with fair and dry weather expected. A shortwave trough passing well north of the area across central Quebec will continue to bring occasional mid to high clouds across northern counties into tonight. Otherwise mainly clear/sunny skies are expected by Wednesday into Wednesday night as temperatures continue to moderate. With southerly return flow well established, tonight`s low temperatures will stay considerably milder than this morning, generally bottoming out from the lower to mid 40s in the Champlain and St. Lawrence Valleys to the mid to upper 30s in the Adirondacks and eastern Vermont. By Wednesday mean 925 mb temperatures climb into the 10-12C range supporting afternoon highs in the lower to mid 60s, with mainly 40s expected for Wednesday night lows.

&& .SHORT TERM /THURSDAY THROUGH SATURDAY NIGHT/... As of 306 PM EDT Tuesday...Area of surface high pressure persists over the southeastern USA as weakening low over northern Quebec attempts to drag a cold front near the international border Thursday. With dry air in place over the North Country - PWATS half inch or less - expect any moisture from front to result in increased clouds, but no precipitation. Behind the front and associated mid-upper level trough, ridging at the surface and aloft build into the northeast. Ridging will persist through the weekend. Temperatures will be above normal throughout the period, starting in the 60s to near 70 on Thursday and cooler on Friday behind the cold front, then rebounding back into the 60s to low 70s for the weekend. && .LONG TERM /SUNDAY THROUGH TUESDAY/... As of 306 PM EDT Tuesday...Sunday will be warm ahead of cold front associated with longwave trough which will dig southward from Ontario. This system will provide multiple chances for showers into the middle of next week. PWATs look to increase to around 1 inch, possibly more in strong SW flow. Wind channeling up the valleys could result in strong gusty winds Monday into Tuesday. && .AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
