Area Forecast Discussion National Weather Service Burlington VT 1034 PM EST Tue Jan 28 2020

SYNOPSIS. Overcast conditions will bring a chance of snow showers and patchy freezing drizzle through the first half of tonight. Some untreated surfaces may remain icy as a result. Surface high pressure eventually builds into the region from Canada, resulting in gradual clearing for Wednesday, and quiet weather conditions through the end of the work week. Our next chance for snow showers arrives Saturday night into Sunday associated with a modest trough and weak surface boundary.

NEAR TERM /THROUGH WEDNESDAY NIGHT/. As of 935 PM EST Tuesday . No changes for the 930 pm update this evening. Ceilings have started to lift a bit, but still overcast skies with some trapped low level moisture causing some freezing drizzle. Overall coverage of drizzle seems to have decreased and will continue to do so overnight. Previous discussion follows.

Northwesterly low- mid level flow and prevailing 2-3kft deep stratus deck continues to yield sporadic snow showers and areas of freezing drizzle, especially over the higher terrain where modest upslope is aiding in precipitation production despite small droplet sizes. Any accumulation will be quite minimal this afternoon through this evening, but with road surfaces near to slightly below freezing, could still see some icy spots on untreated surfaces.

Little change in regional conditions through midnight, but should begin to see some breaks in the overcast develop after midnight, and will help bring lingering FZDZ and --SHSN to a close. Northwest winds will continue at 5-10kt, and lingering clouds will mitigate radiative cooling somewhat. Looking at overnight lows mostly in the teens. If enough clearing takes place in the pre-dawn hours, some single digits will be possible in the Adirondacks and across Vermont's Northeast Kingdom.

Across the higher summits, may see a bit of an undercast develop Wednesday morning as subsidence pushes inversion layer down to 2-3kft. Eventually, we lose saturation in the inversion layer, so should trend partly to mostly sunny by Wednesday afternoon. PoPs NIL. Continued NW flow and gradual CAA over the next 18-24hrs yields highs in the low-mid 20s for Wednesday, except locally 28-32F across s-central VT.

Colder temperatures for Wednesday night as high pressure builds sewd from Ontario and Quebec, with ridge axis cresting over the North Country at daybreak Thursday. Skies are expected to be mainly clear. With light wind conditions, should see good radiational cooling and overnight lows ranging from zero to 5 above across the Champlain Valley, s-central VT, and CT River Valleys. Looking at zero to -10F across the remainder of the region, with the coldest readings in the normally colder spots within the northern Adirondacks and far nern VT. Given setup, the forecast temperatures undercut the MOS consensus by several degrees. PoPs NIL.

SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/. As of 155 PM EST Tuesday . The coldest day of the week is on tap for the North Country on Thursday with high pressure fully entrenched across the region. Even with the high pressure system originating from the higher latitudes, the colder air remains locked up in the arctic. Nevertheless, near normal to slightly below normal temperatures are expected on Thursday with highs generally ranging from the lower to upper 20s. It will actually feel quite pleasant given we should see ample sunshine in the morning and early afternoon followed by filtered sunshine in the late afternoon. Some cloud cover may reside across the North Country heading into the overnight hours which may limit radiational colling so temperatures will likely be 5-10 degrees warmer than Wednesday night. It's looking like lows will range from near zero to about 10 degrees with the possibility of a few locations dropping just below freezing. If cloud cover is more abundant than currently forecasted, we could see temperatures several more degrees warmer.

LONG TERM /FRIDAY THROUGH TUESDAY/. As of 155 PM EST Tuesday . High pressure will remain entrenched across the region again on Friday with some filtered sunshine expected. Temperatures will be a few degrees warmer than on Thursday as the air mass underneath the high slowly moderates. An upper level trough approaching from the west will kick out the high pressure system and bring the return of some rain/snow chances back for the weekend. As has been the trend over the past several days, the northern stream and southern stream branches of the jet stream look like they will remain out of phase. This should keep a developing low over the western Atlantic well east of the 40N 70W benchmark and have no impact on us here in the North Country. On the other hand, we could see some showers as the upper level trough swings through Saturday and Sunday but moisture will be severely lacking as the low over the western Atlantic will ingest most of the moisture. Snow totals will be very limited with little to nothing expected at lower elevations and maybe a few inches toward some of the higher peaks.

Another surge of warm air will work back into the North Country on Monday as we get deep layer ridging building over the region. Monday should be on the dry side but as we head into Tuesday, we will see a potent shortwave passing along the northern periphery of the building ridge which could bring some rainfall to the region. Temperatures on Monday will warm into the mid 30s with upper 30s to mid 40s expected on Tuesday. Even with these warmer temperatures and southwesterly flow aloft, the main moisture axis will reside to our south so it doesn't look like rain will be heavy if we get any early next week.

AVIATION /03Z WEDNESDAY THROUGH SUNDAY/. Through 00Z Thursday . MVFR cigs along with HIR TRRN OBSCD will prevail through 06Z tonight. Cloud layer is just deep enough to generate occasional/intervals of very light snow shower activity or freezing drizzle through midnight, though prevailing conditions will generally be free of precipitation at the TAF locations. Little to no accumulation anticipated. Winds will remain NWLY at 5-10kts. Should trend VFR with BINOVC developing during mid morning thru early aftn hrs Wednesday. Ceilings will lift Wednesday afternoon and scatter out finally.

Outlook .

Wednesday Night: VFR. NO SIG WX. Thursday: VFR. NO SIG WX. Thursday Night: VFR. NO SIG WX. Friday: VFR. NO SIG WX. Friday Night: VFR. NO SIG WX. Saturday: Mainly VFR, with areas MVFR possible. Chance SHSN. Saturday Night: Mainly VFR, with local MVFR possible. Chance SHSN. Sunday: Mainly VFR, with local MVFR possible. Chance SHSN.
