Area Forecast Discussion National Weather Service Burlington VT 332 PM EDT Thu Oct 21 2021

SYNOPSIS. Scattered light showers will affect mainly the northern half of the North Country today. However, most of the day will remain dry, mostly cloudy, and mild. Widespread heavier rain showers will quickly sweep eastward late tonight along a cold front that will usher in a return to more seasonable conditions. Aside from possible mountain rain and snow showers, mainly dry conditions are expected through at least Monday.

NEAR TERM /THROUGH FRIDAY NIGHT/. As of 331 PM EDT Thursday . Surface warm front associated with low pressure north of the eastern Great Lakes has lifted north of the Canadian border this afternoon and satellite imagery shows that a mid-level dry slot is beginning to eat away at low level moisture with breaks of sun developing across northern New York. Dry conditions and breaks in the clouds will prevail through the evening hours until the low tracks northeast into the St. Lawrence and Ottawa Valleys, dragging a sharp cold front into the region overnight. Rain will become widespread across northern New York by midnight, and then eastward across Vermont during the pre-dawn hours of Friday. By sunrise the front will be situated somewhere close to the Champlain Valley, and promptly exit east of the Connecticut River Valley by early afternoon with the region rain-free after the noon hour. Storm total rainfall amounts look to be 0.5-0.75" across northern New York, to 0.25-0.5" in northern Vermont, and only a couple tenths of an inch in southern VT.

Behind the front, temperatures will be dropping sharply back to seasonal normals which for this time of year is highs in the mid 50s and lows in the 30s. Expect temps to remain fairly steady in the 50s through midnight, then begin to fall across western areas into the 40s by daybreak. Thereafter expect a stark contrast in temps from northwest to southeast across the CWA with cold air advection keeping temps in 40s across New York, while central/southern Vermont warm into the upper 50s to lower 60s ahead of the front. Northern areas of Vermont will see temps slowly fall through the day starting in the mid 50s, and ending in the mid/upper 40s by sunset.

For Friday night, forecast soundings show a strong subsidence inversion setting up around 4000 feet with an abundance of low level moisture trapped below. This supports cloudy conditions continuing which will mitigate the development of frost given low temps will be widespread in the mid/upper 30s. The higher summits however will likely be above the clouds, especially over the Adirondacks.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. As of 331 PM EDT Thursday . Changes were relatively minor for this weekend with the region mainly under broad cyclonic flow for Saturday with the pattern becoming more progressive by Sunday as high pressure moves over the southern Hudson Bay. This pattern will promote cooler temperatures overall with continued cloud cover and some low chances of sprinkles or a stray light shower. Some frost could develop Saturday and Sunday nights over the Adirondacks to areas just west of Plattsburgh and east of the Green Mountains mainly north of Interstate 89 if skies can clear enough for efficient radiational cooling; these locations could also see some freezing morning lows for Sunday and Monday morning. Elsewhere, temperatures will remain above freezing with lows in the mid 30s up to around 40 degrees. Cooler high temperatures will be on tap as well with 925mb temperatures in the 1- 3C range; generally expected highs in the mid 40s to low 50s.

A weak short wave will be rotating around the southwestern periphery of the upper low Saturday evening through Sunday. This will promote chances of showers mainly in St Lawrence County, but could see some showers spread to the Adirondacks as well. Chances from the Adirondacks through the Champlain Valley into eastern Vermont are more nebulous because the upper low will be exiting into eastern Canada while the minor shortwave moves west to east through the region on Sunday. Expect at least some cloud cover and possibly a few sprinkles across the North Country Sunday afternoon and evening.

LONG TERM /MONDAY THROUGH THURSDAY/. As of 331 PM EDT Thursday . Main changes for the extended forecast were to delay the approach of precipitation associated with the next system. The latest consensus of model guidance favors a more southerly position high pressure in the vicinity of Hudson Bay by Monday. Most guidance agrees that this will shunt the semi- stationary boundary associated with the next system down towards the I-90 corridor keeping showers at bay until the approach of the system itself later next week. As such, precipitation should begin to return after midweek with Thursday and Friday as good contenders for wetter and breezy days with temperatures warming back to the mid/upper 50s as flow increases out of the south.

AVIATION /20Z THURSDAY THROUGH TUESDAY/. Through 18Z Thursday . Improving conditions are expected for this afternoon through midnight with MVFR showers shifting east of the region and ceilings lifting ahead of a cold front. After midnight, conditions will rapidly deteriorate from west to east along the frontal passage with widespread MVFR and local IFR at KSLK developing. Post frontal passage after 12Z Friday, conditions aren't likely to improve much either with a low level inversion setting up. Vsby will improve to VFR, but low ceilings will prevail. Winds will be less than 10kts through the period.

Outlook .

Friday Night: VFR. NO SIG WX. Saturday: VFR. Slight chance SHRA. Saturday Night: VFR. Slight chance SHRA, Slight chance SHSN. Sunday: VFR. Slight chance SHRA. Sunday Night: VFR. Slight chance SHRA. Monday: VFR. NO SIG WX. Monday Night: VFR. Slight chance SHRA, Slight chance SHSN. Tuesday: VFR. Slight chance SHRA.
