Area Forecast Discussion National Weather Service Burlington VT 303 AM EST Sat Feb 27 2021
SYNOPSIS. A weak frontal system will bring light snow changing to a mix then rain to the region today. Sunday will be mostly dry as weak high pressure moves by. Another front will pass through the area on Monday with rain and snow showers in the morning, but a stronger Arctic cold front will bring snow showers or squalls later Monday. Temperatures trend mild into Monday morning before falling with much colder air later Monday into Tuesday. Temperatures will moderate once again for the rest of next week.
NEAR TERM /THROUGH SUNDAY/. As of 303 AM EST Saturday . A wide range of temperatures early this morning as sheltered areas are quite cold while other locations are feeling the warming effects of the southerly gradient and strong warm advection. This warm advection associated with a weak warm front will push through the area today with a 4-6 hour window of mainly light precipitation, mainly from mid morning through mid to late afternoon. Soundings suggest that this will mainly be a light snow to light rain event, though still a chance a brief period of mixed light sleet or freezing rain across the northern SLV and Green mountains eastward. Any icing threat appears minimal, though will maintain a few spots with light totals less than a tenth of an inch in the mountains. A weak occluded front moves through during the afternoon and evening and precipitation tapers off from west to east rather quickly. Snow totals generally an inch or less in the broad valleys and 1-2" elsewhere. Temperatures will be on the rise through the day with late high temperatures in the upper 30s to lower 40s.
It will be a mild evening as temperatures hold in the 30s to around 40 for the first part of the night. Conditions to trend dry overnight as a weak axis of high pressure traverses the area but can't rule out some higher elevation rain or snow showers for the first part of the night. Variable clouds will likely linger in the mountains with the broad valleys trending partly cloudy as lows hold on the mild side in the 20s to around 30.
A ridge of high pressure will be over the region to start off Sunday with clouds increasing from southwest to northeast during the afternoon in the day in advance of warm advection associated with another frontal system. There is a chance of mainly light rain showers late afternoon to early evening to the south and west of BTV as high temperatures remain mild in the lower 40s.
SHORT TERM /SUNDAY NIGHT/. As of 351 PM EST Friday . After a brief break in the action, more precipitation will move into the North Country as yet another warm front moves through the area. This time lighter and more scattered shower activity is anticipated as good dynamics are poised to pass well to our north associated with the parent low pressure system over southern Canada. Temperatures at the surface and for a substantial layer aloft will rise above freezing supporting all rain just about everywhere. A surface cold front then moves through Sunday night, probably in the midnight to 6 AM period, from west to east, which will gradually cool the column to allow lingering rain showers to change to snow on strengthening westerly winds towards daybreak.
LONG TERM /MONDAY THROUGH FRIDAY/. As of 351 PM EST Friday . Modestly cooler air, seasonable for the end of February, will be in place on Monday with weak cold air advection. Unblocked westerly flow will promote some flurries and snow showers over the higher terrain. The main story for the extended period continues to be the potential impacts of an Arctic cold front that will promote briefly heavy showers, strong winds, and rapid temperature falls that could come together just right for snow squalls. The latest data continues to suggest timing relatively late in the day, from around 6 PM through 11 PM. Much of the deterministic guidance suggests the surface low tracks near and then south of the Adirondacks, which would push the threat for heavy snow squalls primarily to our south, but even in this case widespread snow showers and sharply colder air would blast into the region Monday night. A quick inch or two of blowing snow is the most likely result from this event, with several hours of widespread post- frontal northwesterly wind gusts over 30 MPH. The windiest weather will be favored in eastern Vermont where enhanced downsloping is probable, and the duration will be pretty long given how sharp the front and associated advection appears. Temperatures will plummet from near freezing to the single digits above zero by daybreak. Little warming will take place on Tuesday with highs mainly in the teens.
For the rest of the week, while there are some indications of another surge of colder air for the end of the week, the theme will be more pleasant conditions with low chances for precipitation given fast zonal flow. Temperatures should recover back to a few degrees above normal values for Wednesday with no significant changes through Friday.
AVIATION /08Z SATURDAY THROUGH WEDNESDAY/. Through 06Z Sunday . VFR through 12Z as high pressure departs east with just some high clouds moving into the region overnight. Winds variable and generally less than 10 kts through the overnight. After 12Z warm front moves into the region with widespread light snows/rains developing southwest to northeast in the 12-15Z time frame. Conditions lower to IFR/MVFR in this time frame,during which enhanced southerly low-level wind shear from 35-45 kt is expected at all terminals. From 21-03z look for an improvement to VFR as precipitation ends from west to east across the area as a weak occluded front and drier air moves into the area and winds shift to westerly.
Sunday: Mainly VFR, with local MVFR possible with a chance -SHRA late. Sunday Night: Mainly MVFR, with local IFR possible. Chance RA. Monday: Mainly VFR, with areas MVFR possible. Chance SHSN, Chance SHRA. Monday Night: VFR. Windy with gusts to 30 kt. Likely SHSN. Tuesday: VFR. NO SIG WX. Tuesday Night: VFR. NO SIG WX. Wednesday: Mainly VFR, with local MVFR possible. NO SIG WX.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
