851 FXUS61 KBTV 011908 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 308 PM EDT Sat Nov 1 2025 .SYNOPSIS... Winds decrease this evening with temperatures becoming warmer through Wednesday as highs climb back into the upper 40s and 50s. A fast moving system moves through Monday and Monday night bringing the next chances of precipitation with additional chances possible for Thursday. && .NEAR TERM /THROUGH SUNDAY NIGHT/... As of 232 PM EDT Saturday...Ridging will quickly build across the region tonight through Sunday while 500mb flow remains mostly zonal. Cold air advection increases this evening with flow out of the west; lows tonight expected to range in the 20s to low/mid 30s despite lingering cloud cover. The pattern transition will support temperatures warming into the upper 40s to around 50 degrees tomorrow while allowing for breezes to drop. What would have been a good radiational cooling set up Sunday night will be disrupted by winds increasing ahead of the next system. Best chances to bust the current forecast of lows in the mid/upper 20s for lower temperatures in the lower 20s will be east of the Greens at lower elevations. This will be dependent on timing of wind increases and any slower onset will support the cooler temperatures. Otherwise, lows will generally be in the upper 20s to low/mid 30s. && .SHORT TERM /MONDAY THROUGH MONDAY NIGHT/... As of 232 PM EDT Saturday...Southerly breezes are anticipated to increase Monday with flow aloft exceeding 30 mph with surface gusts 20-25 mph especially over Lake Champlain where mixing will be strongest. Southerly winds will help temperatures to warm into the 50s for most spots, but rain chances sharply increase after sunrise for the St Lawrence Valley and after noon for locations in Vermont. A fast moving front is expected to sweep through. The speed of the system related to zonal flow aloft will keep precipitation amounts on the lower end of the spectrum, generally less than 0.25". It should be noted, that model trends for an earlier system approach have continued with highest chances now before noon for northern New York and through early afternoon for Vermont. Rainfall is expected for most locations, but some light snow is probable for higher summits on the back end of the system. Winds are likely to continue behind the front with neutral to cool air advection anticipated keeping lows generally in the 30s to around 40 degrees. && .LONG TERM /TUESDAY THROUGH SATURDAY/... As of 232 PM EDT Saturday...A few rain and mountain snow showers could linger into Tuesday morning, but dry air enters quickly behind the front so anything should be light and brief. A more zonal pattern will persist through the end of the week with the passage of a couple weak shortwaves. A period of elevation dependent rain/snow is possible Wednesday into Wednesday night but the system looks to be moisture starved so any precipitation totals will be relatively light. Early estimates of snow levels look to be in the 2,000 to 3,000 foot range but those will be dependent on the intensity of the system/precipitation and the ability of the colder air to catch up with the system in time. A more potent storm system looks to arrive over the weekend and into early next week, but with a projected track to the west and plenty of warm-air advection ahead of it, it looks to be mostly if not all rain. Temperatures during this stretch should end up averaging around climatological normals. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... Through 18Z Sunday...Lingering showers remain only in eastern Vermont, mainly KEFK. Ceilings at KSLK are currently about 700 ft agl, but will lift soon with the sunrise. A mix of MVFR and VFR conditions will prevail the next 24 hours due to 1800-4000 ft agl ceilings. West-southwest and west-northwest winds of 8 to 15 knots sustained with gusts 18 to 28 knots will continue through about 22z. After that, winds will slowly abate. Outlook... Sunday: VFR. NO SIG WX. Sunday Night: VFR. NO SIG WX. Monday: Mainly VFR, with local MVFR possible. Chance SHRA. Monday Night: Mainly VFR, with local MVFR possible. Definite SHRA. Tuesday: VFR. Chance SHRA. Tuesday Night: VFR. NO SIG WX. Wednesday: VFR. Chance SHRA. && .MARINE... A Lake Wind Advisory remains in effect through today. West to northwest winds of 20 to 25 kts with gusts to around 35kts will continue into the evening before subsiding overnight. Therefore, the Lake Wind Advisory will stay in place at least through the daylight hours. Waves will be 3 to 5 feet. && .BTV WATCHES/WARNINGS/ADVISORIES... VT...None.
