High pressure builds into the region today into Saturday with skies trending mainly clear and seasonably cool temperatures. Showery weather arrives for Sunday as another front sweeps into the region, followed by a return to seasonable and mainly dry weather for much of next week with mild afternoon highs and cool overnight lows. && .NEAR TERM /THROUGH SATURDAY/... As of 306 AM EDT Friday...Cloudy skies this morning will trend mainly clear by later today into this evening as high pressure builds east from the Great Lakes. Outside some patchy morning drizzle in a few spots, dry weather is expected. Highs today reflect cool nature of Canadian airmass advecting into the region on modest northerly flow - mainly 60s. Clear skies and light winds will then be the rule tonight as center of the high bridges atop the region. Ideal radiational effects expected with lows bottoming out generally in the 35 to 45 range, milder near Lake Champlain. Probabilities of slightly lower readings highest in the Northeast Kingdom where a Frost Advisory has been posted for favored valleys/hollows of Essex and Caledonia Counties. A beautiful day remains on tap for Saturday as the surface high remains atop the region. Some filtered high clouds may arrive late from the west, but largely sunny skies are expected as highs top out in the upper 60s/lower 70s under light southerly return flow. && .SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/... As of 306 AM EDT Friday...The high pressure responsible for our nicer weather will shift eastward over the Atlantic Ocean Saturday night which will moisture to begin streaming back into the region. Looking at the NAM and GFS guidance for Saturday night, decent moisture advection and warmer air filtering into the 850 mb and 925 mb levels should help increase cloud cover across northern New York and western Vermont through the overnight hours. Eastern Vermont will likely be clearer through much of the overnight period which will allow them to be quite a bit colder than further west. Overnight lows Saturday night will range from the mid 40s to mid 50s with the coldest temperatures occurring across eastern Vermont. Rainfall ahead of an approaching cold front will move into the St. Lawrence Valley Saturday morning after 8 AM. All of the latest 00Z guidance continues to delay the onset of rainfall across the North Country which is attributed to the upper level low over the Four Corners region weakening into an upper wave. Nevertheless, widespread rain showers will be seen throughout the region during the daylight hours on Sunday with most places seeing a quarter of an inch to a half of an inch of rainfall. The only exception to this will be across far southeastern Vermont where rainfall amounts are expected to be less than 0.15" as they will be well removed from the best forcing. We continue to look at strong gradient winds developing Sunday morning and continuing through the afternoon hours across the northern Champlain Valley. Unlike the wind event last week, the strongest winds this time will likely be tied to Lake Champlain with wind gusts in the 35 to 45 mph. As you head away from the lake, wind gusts in the 20 to 30 mph range look more likely. The winds should peak during the early afternoon hours as mixing within the marine boundary layer helps to mix down some stronger winds from around 1500 ft. Once the sun sets, any mixing will cease and winds will slowly relax as the pressure gradient begins to weaken. Given a strong southwest low level jet across the Adirondacks and Green Mountains, we will likely see rain shadowing across portions of the Champlain and St. Lawrence Valleys which could yield slightly lower rainfall amounts than previously mentioned. A few lingering showers will likely continue overnight Sunday into early Monday morning as the upper level trough axis passes through. Any additional rainfall will be light with just a few hundreths of an inch of rain expected. Overnight lows will once again be on the warm side as we should see mostly cloudy skies persist through the overnight hours. && .LONG TERM /MONDAY THROUGH THURSDAY/... As of 306 AM EDT Friday...Tranquil weather is in store for next week as we see high pressure settle across the North Country. Noticeably colder temperatures will be seen on Monday and Tuesday with highs only climbing into the lower to mid 60s with lows in the mid 30s to mid 40s. Patchy frost is expected across northeastern Vermont and portions of the northern Adirondacks once again Monday night and Tuesday night. We will see a warming trend on Wednesday and Thursday with our temperatures returning to near normal values but another cold front on Thursday will bring below normal temperatures to the region to end the upcoming week. There could be a few rain showers with the front on Thursday but the surface low will once again track well north of the international border which will leave us on the tail end of the cold front. && .AVIATION /07Z FRIDAY THROUGH TUESDAY/... Through 06Z Saturday...Frontal boundary continues to pull south and away from the area. Lingering MVFR/brief IFR expected through 12Z in moist post-frontal northerly flow with patchy drizzle possible. Quick improvement to VFR is expected at all terminals in the 12-18Z time frame, with SKC conditions after 21Z as surface high pressure builds into the region. Winds northerly generally from 6-12 kts, occasionally gusty into the 14-18 kt range this afternoon before abating to near calm after 00Z Saturday. Outlook... Saturday: VFR. Patchy BR. Saturday Night: VFR. Slight chance SHRA. Sunday: Mainly VFR, with areas MVFR possible. Windy with gusts to 30 kt. Likely SHRA. Sunday Night: MVFR/IFR conditions possible. Chance SHRA.
