-- Changed Discussion --
As of 955 AM EDT Wednesday...Very little to change with this update, just blended in some locally run hi-resolution BTV4 model sky cover to pick up some of the diurnal stratocumulus developing mainly in the mountains. Otherwise no changes to temp/wind/weather fields. Isolated showers are possible today with upper level trough making its way across the North Country. This will be a cooler drier air mass with dewpoints dropping to more comfortable temps, low to mid 50s. Temperatures today will be a bit cooler than seasonal normals, only reaching the lower to mid 70s.

&& .SHORT TERM /8 PM THIS EVENING THROUGH FRIDAY/... As of 400 AM EDT Wednesday...Will continue with chance for showers as upper level trough slowly pushes eastward across Northern New York and Vermont. Best chance for showers will be Thursday afternoon. Temperatures throughout the period will be slightly cooler than normal with the upper level trough overhead. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... As of 400 AM EDT Wednesday...Little change to the forecast as surface high pressure builds into the region from Ontario with generally light northerly flow filtering drier air through at least Sunday night. Aloft, a mid- level trough will continue to reside over the northeast. An area of vorticity looks to swing through the region Saturday into Sunday, providing a slight chance of showers mainly for the higher terrain during the daytime. Mid-level ridging begins Monday through Tuesday night, while at the surface, the ridge axis will begin to move north and east, putting the North Country in southerly flow for the beginning of the work week. This will result in the slightly below normal temperatures throughout the period warming on Monday and Tuesday to near normal. && .AVIATION /14Z WEDNESDAY THROUGH SUNDAY/... Through 12Z Thursday...MVFR cigs at KSLK and KRUT will lift this morning. Otherwise VFR conditions will persist through the next 18 hours for all sites. Winds generally out of the SW at 8-13kts with gusts of 15-25kts developing this morning. After sunset, winds subside around 5kts or less.
