As of 205 PM EDT Wednesday...Going forecast on track. 925mb temps around 12C at BTV per RAP this afternoon which should yield max temps in the mid 60s in the valleys lower 60s in the hills this afternoon which is well covered in the going forecast. Very quiet wx through the near-term. Generally looking at clear skies otherwise through tonight. The sfc ridge axis extending along the east coast of the U.S. and building shortwave ridging aloft will bring dry weather, but southerly pressure gradient increases overnight especially west of the Greens with light south to southwest winds and moderating temperatures. Only a very small chance for any radiation fog east of the Greens so left it out. Lows mainly in the 40s for tonight except near 50 in the St. Lawrence and Champlain valleys. Temperatures moderate further on Thursday under a rather strong west southwest flow with 850-mb winds 30 to 50 kts leading to breezy surface winds of around 15 kt with gusts to 25 to 30 kt. With 925-mb temps around 14C for looking for max temps reaching the upper 60s to lower 70s. Another mid-upr level shortwave trough is progged to pass along the intl border Thursday afternoon. This feature should bring an increase in mid-upr level clouds, but dry low-level conditions should preclude any precipitation.

&& .LONG TERM /SUNDAY NIGHT THROUGH TUESDAY/... As of 329 AM EDT Wednesday...Coming out of the weekend expect a full latitude trough digging into the eastern CONUS which will bring several chances for showers to the region. The first chance will be a front that moves through late Monday into Tuesday with the best chance being towards the midweek as a closed low should develop over the Great Lakes and advances a stronger frontal system through the North Country. Global models are depicting a 995mb low over the Great Lakes with a 1020mb high out over the Atlantic. The resulting pressure gradient should lead to fairly gusty winds with the potential for 15-25 mph with gust to 30mph of southwest funneled valley flow on Tuesday. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
