Area Forecast Discussion National Weather Service Burlington VT 157 AM EDT Fri Apr 16 2021

SYNOPSIS. Widespread rain will transition to mountain snow late this evening and continue throughout the day on Friday. Generally drier conditions are forecast for the weekend, but some spotty showers are possible. Unsettled conditions continue into next week with on and off chances for showers.

NEAR TERM /THROUGH SATURDAY/. As of 1032 PM EDT Thursday . Winter Storm Warnings and Winter Weather Advisories remain in effect now through 8 PM Friday for portions of central and southern Vermont as well as Essex County in New York. Forecast remains on track, with precipitation ending over the St. Lawrence Valley but persisting elsewhere. Snow levels have continued falling, allowing for some light accumulations on grassy surfaces even to areas below 1000 feet in eastern Vermont based on area webcams. While valley locations are seeing snowflakes, relatively warm surface temperatures in the upper 30s to low 40s over will preclude accumulations for the next few hours. However, with this update, I have broadened areal coverage of snow accumulations in northeastern New York and eastern Vermont, as periods of heavier snowfall will help cool the air and the ground temperatures, supporting light snowfall across most low elevation sites in the overnight hours outside of the Champlain Valley where relatively mild air will exist due to a southeast low-level jet.

Previous Discussion . We should start to see a transition to snow above 1500 feet around 8 PM this evening, while locations below 1500 ft will see a mix of rain and snow. During this time, the coastal surface low will continue to track along the East Coast causing the area of heaviest precipitation to become focused across south- central Vermont, especially along and atop the eastern slopes of the Green Mountains. Wet mountain snow will be heavy at times, especially during the overnight hours. For such reasons, isolated power outages are possible.

Precipitation will continue throughout the day on Friday either as rain, a rain/snow mix, or snow depending on elevation. Temperatures will remain on the chilly side for Friday thanks to cold air advection and ongoing precipitation with highs only in the upper 30s to low 40s. By Friday night, precipitation will begin to wane from west to east. Not a lot of change to the overall snow totals with areas above 1500 ft across south- central Vermont expected to receive 6 to 12 inches, while areas above 1500 ft across north-central Vermont and the high peaks of the Adirondacks expected to receive 2 to 6 inches by Friday night. Elsewhere, then an inch expected.

SHORT TERM /SATURDAY NIGHT/. As of 336 PM EDT Thursday . By Saturday morning, precipitation will have mostly come to an end as the surface low ejects eastward into the Atlantic. Still, we could see a few lingering mountains snow showers early in the day. Temperatures will be slow to recover on Saturday as we remain under northerly flow and cloudy skies. Highs will be in the 40s with overnight lows Saturday night into Sunday morning in the 30s.

LONG TERM /SUNDAY THROUGH THURSDAY/. As of 336 PM EDT Thursday . A general trend toward drier weather is expected for the Sunday/Monday time frame with weak high pressure in the lower levels. A few weak, shortwave ripples still traverse the area aloft during this time period however, so the idea of widely scattered, diurnally forced showers mainly across elevated terrain still appears reasonable. Temperatures rebound to seasonably mild levels with 50s expected on Sunday, and mid 50s to around 60 by Monday.

Looking further out, a cold front is still on track to swing through the area during the mid-week time frame with renewed chances of showers. Consensus blends suggest the timing has slowed slightly, focused mainly in the Tuesday night/Wednesday morning time frame so have adjusted solid chance PoPs accordingly. Some nominal mix/changeover to wet snow is also possible across the northern high terrain as post-frontal thermal profiles cool aloft. Any accumulations would be minor however. Behind this feature a general return to dry and slightly cooler weather is expected by the end of the work week.

AVIATION /06Z FRIDAY THROUGH TUESDAY/. Through 06Z Saturday . Overall trend for the period will be towards deteriorating conditions where flight categories are currently VFR down to MVFR, and where IFR is currently persistence is the forecast. A mix of rain and snow will continue through much of the period with vsby generally 4-8SM in rain, and 1-3SM in snow. Wind will be variable less than 10kts through mid-morning, then trend northerly at 8-12kts.

Outlook .

Saturday: Mainly VFR, with areas MVFR possible. Slight chance SHRA. Saturday Night: Mainly VFR, with local MVFR possible. NO SIG WX. Sunday: Mainly VFR, with local MVFR possible. Chance SHRA. Sunday Night: Mainly VFR, with local MVFR possible. NO SIG WX. Monday: Mainly VFR, with local MVFR possible. Slight chance SHRA. Monday Night: VFR. NO SIG WX. Tuesday: VFR. Slight chance SHRA.

BTV WATCHES/WARNINGS/ADVISORIES. VT . Winter Storm Warning until 8 PM EDT this evening for VTZ012- 018-019. Winter Weather Advisory until 8 PM EDT this evening for VTZ008- 010. NY . Winter Weather Advisory until 8 PM EDT this evening for NYZ034.
