Area Forecast Discussion National Weather Service Burlington VT 1030 AM EDT Wed Apr 8 2020
SYNOPSIS. A relatively quiet day with near normal temperatures can be expected across the region today. Meanwhile, a deepening area of low pressure along with a cold front will produce a widespread cold rain on Thursday. As temperatures cool across the higher terrain of northern New York and Vermont, the precipitation will change to a heavy wet snowfall, with 2 to 6 inches possible by midday Friday. Areas of slippery travel are likely, along with the potential for isolated power outages for mountain locations above 1500 feet. Lingering rain and snow showers taper off by Saturday with below normal temperatures expected into the upcoming weekend.
NEAR TERM /THROUGH THURSDAY/. As of 1023 AM EDT Wednesday . Sharp difference in cloud cover persists across the North Country with mostly clear conditions north and east of BTV, and overcast conditions across St. Lawrence County, the Adirondacks, and into central and s-central VT. Current sky cover trends should generally prevail thru the afternoon, with just limited breaks in the overcast across southern sections. Have made some slight adjustments to clouds and temperatures as a result. Temperatures generally cooler than the past two days, with highs in the upper 40s to mid 50s and continued N-NE winds at 5-10 mph.
Looking forward in time, a heavy wet accumulating snowfall is possible for the northern dacks into the northern/central Green Mountains of VT, including the NEK Thurs into Friday as a very dynamic system with complex thermal profiles impacts the region. Areas of slippery travel across the higher trrn is likely, along with the potential for isolated power outages. Crnt snowfall of 2 to 6 inches is possible above 1500 feet with localized higher amounts at summit level by midday Friday.
Overall, synoptic scale pattern remains unchanged with vigorous short wave energy ejecting from closed 5h circulation over the northern Great Lakes on Thurs Morning, helping to enhance rapid cyclogenesis of sfc low pres in the Gulf of Maine by 00z Friday.
Initially thermal profiles are just warm enough to support a cold rain acrs the entire fa on Thurs morning. However, as strong dynamics arrive with associated sharp height falls, the column cools to produce a change over to wet snow acrs High Peaks of the dacks by mid-morning and mid aftn for the Green Mountains of VT, including the NEK. Progged 850mb temps start in the 1-3C range, but quickly cool btwn -2c and -4C by 00z Friday, as cold core mid/upper lvl circulation with 500mb temps near -36C moves directly overhead. Meanwhile, cooling at 925mb lags with values dropping to near 0c by 00z Friday, supporting the idea of snow levels near summit level falling to 1500 to 2000 feet range by early evening. Given the favorable jet dynamics and high precip rates with boundary, thinking column cools enough during period of heaviest precip to support snow, especially in the higher trrn on Thurs aftn. Snowfall accumulations thru 00z Friday mainly in the 1 to 3 inch range with isolated amounts of 4 to 5 inches possible near summits.
Meanwhile, bl temps in the valleys support a cold rain maybe mixed with a few wet snowflakes toward 21z Thurs. Have integrated the high resolution nam3km 2m temp proggs into grids, showing the rapid fall in temps as precip arrives and becomes heavy at times on Thurs. Temps start in the upper 30s to mid 40s, but fall into the 30s areawide by late aftn.
Rainfall amounts have trended slightly higher, given the available moisture and extremely strong dynamics with qpf values ranging from 0.50 to 1.0" for the event. Thinking some in bank rises on local waterways are likely by Friday, but not anticipating any hydro related issues attm. Still expecting a period of breezy conditions behind the boundary on Thurs aftn/evening with localized gusts up to 35 mph possible, especially SLV on aligned sw to ne flow.
SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY/. As of 348 AM EDT Wednesday . Widespread precipitation will taper off into showers Thursday night, mainly lingering over the higher terrain of the Northeast Kingdom, northern Greens, and northern Adirondacks. Cold air advection will be ongoing through the night, with 850 mb temps dropping to -6 to -7 deg C by Friday morning. Accordingly, freezing levels will lower through the night and will see a transition to snow showers as predominant ptype for all but the lowest elevations by Friday morning. Valley locations will see a rain/snow mix with little to no snow accumulation. However, setup is looking increasingly favorable for some snow accumulations in higher terrain as upper- level low stall and pivots over the forecast area. Storm total snow through Friday will be in the 2 to 5 inch range for much of the Northeast Kingdom and portions of the northern Adirondacks. Higher peaks (generally 1500 ft and above) of the NEK and northern Greens have the potential for 6+ inches. Winter Weather Advisories may be needed for portions of northern Vermont, but given that the heavier accumulations will be restricted to 1500 ft and above, have elected to hold off any headlines at this point. Elsewhere, valley locations will see some some snow mixing in with rain Friday morning, but any snow/rain mix would be brief and accumulations are not expected. Forecast soundings indicating a deeply mixed boundary layer Friday, so expect some gusty winds in addition to the snow showers. Highs will be in the low to mid 40s throughout the forecast area Friday.
LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/. As of 348 AM EDT Wednesday . Residual showers will come to an end Saturday morning as the upper low finally clears the area and weak ridging begins to build in from the west. A northern stream shortwave dropping down from the northwest will keep some clouds in the area for the first part of Saturday, but by Saturday afternoon should see increasing sun. Highs will be again in the low to mid 40s.
Sunday will feel more spring-like as high pressure crests overhead and highs return to the low to mid 50s. Precipitation chances ramp back up Sunday night through Monday as a low pressure system lifts northeastward out of the Ohio River Valley, driving a series of fronts through the North Country. Although details are still murky, there is at least agreement among deterministic and individual ensemble members of a general storm track to our northwest . so continues to look like a predominantly rain event for most of the northeastern US.
AVIATION /15Z WEDNESDAY THROUGH SUNDAY/. Through 12Z Thursday . VFR conditions prevail for the next 18 hours before lowering cigs and rain develops from west to east acrs our taf sites by 12z Thurs. Expecting MVFR cigs to develop at MSS/SLK by 10z, with vis in the 4 to 6sm range in light rain by 12z. Elsewhere cigs generally sct to bkn at 8000 to 12000 feet agl will become overcast at 3500 to 6000 feet agl tonight with light north/northeast winds at 4 to 8 knots.
Thursday: Mainly MVFR, with local IFR possible. Definite RA. Thursday Night: Mainly VFR, with areas MVFR and IFR possible. Likely SHSN, Chance SHRA. Friday: Mainly MVFR and IFR, with areas VFR possible. Likely SHRA, Likely SHSN. Friday Night: Mainly VFR, with areas MVFR possible. Chance SHRA, Slight chance SHSN. Saturday: Mainly VFR, with areas MVFR possible. NO SIG WX. Saturday Night: VFR. NO SIG WX. Sunday: VFR. NO SIG WX.
