Area Forecast Discussion National Weather Service Burlington VT 530 AM EST Fri Dec 6 2019

SYNOPSIS. Weak low pressure will bring an additional round of light snows to the region today through early evening. Mainly dry and colder weather arrives in the wake of this system later tonight into Saturday before temperatures rebound nicely by this coming Sunday. The milder trend continues into early next week with increasing chances for rainfall by Monday afternoon into Tuesday.

NEAR TERM /THROUGH SATURDAY/. As of 530 AM EST Friday . Minor updates to PoPs through the morning hours, mainly to speed up arrival time of light snows by 1-2 hours per latest observational/remotely sensed data. The rest of the forecast remains in good shape. Have a great day.

Prior discussion . The forecast remains on track for today showing another light snow event affecting the region from mid morning onward into early evening. Northern stream clipper- type energy will track from the eastern Great Lakes through the Mohawk Valley this afternoon before exiting offshore later this evening. As is typical with this type of system, primary mid- level frontogenetical forcing will set up immediately north of the low track and have maintained higher snowfall amounts across southern areas accordingly. Leaned more heavily toward NBM snow ratios and a multi-model consensus on QPF, downplaying the higher NAM output which appears overly aggressive with a weaker continental system such as this. This yields snowfall totals of a dusting to 2 inches in the northern valleys, 1-3 inches across the Adirondacks and higher elevations of the northern Greens, and 2-4 inches across southern Vermont with perhaps a few spot 5 inch totals at elevation there. Highs today to remain seasonably cold under a light wind regime - 20s to around 30.

Steadier light snows will taper off through the early evening hours as best forcing exits quickly east leaving only scattered flurries/snow showers in elevated terrain overnight. Some partial clearing will be possible in the Champlain Valley and southern VT after midnight with low temperatures bottoming out mainly in the teens.

Then seasonably cold on Saturday outside a few lingering flurries as strong 1030+ hPa surface high builds into the region. Still some variable cloud cover with moisture becoming trapped beneath building synoptic mid-level inversion but no appreciable accumulations are expected. High temperatures to range through the 20s under light northwesterly winds.

SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY/. As of 429 AM EST Friday . Saturday night will feature surface high pressure ridging into the Northern New York and Vermont area, as well as an upper level ridge moving in. Minimum temperatures Sunday morning will be cold, mainly single digits to around ten degrees. On Sunday, surface high will slide eastward off the New England coast, and south-southwesterly return flow develops. Temperatures will warm into the lower 30s to lower 40s, warmest in the Saint Lawrence valley. Pressure gradient increases during the day and winds will gust to 30-40 mph, higher over Lake Champlain. Some clouds will also move into the area on Sunday afternoon with increase in mid level moisture.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. As of 429 AM EST Friday . Sunday night onwards will feature more active weather with several systems impacting the North Country. Mid/Upper level ridge remains anchored off the Southeast CONUS. Developing southwest 925mb to 850 mb jet of 40 to 50 knots advects a very warm air mass into the area. Warm air advection later Sunday night into Monday morning will bring developing rain showers, with possible mixed precipitation early Monday morning where some cold air remains trapped in the valleys East of the Greens. Surface low deepens and tracks northward through the Great Lakes region Monday night into Tuesday, eventually sharp surface cold front reaches our area later Tuesday. Precipitable water values climb above 0.75" with flow off the Gulf of Mexico and convergence just ahead of approaching cold front. Jet dynamics also aid in moisture advection and convergence, therefore could see some enhanced rainfall amounts though it's a bit far out to zero in on those details just yet. Still think that rainfall will range from about a quarter of an inch to three quarters of an inch, locally around an inch in favorable southwest upslope regions of the Dacks and Greens. Temperatures will be mild Monday and Tuesday with warm air advection despite clouds and precipitation moving in generally ranging through the 40s but some spots will get close to 50. Temperatures will fall sharply behind departing cold front later Tuesday afternoon and overnight, and winds will become gusty out of the west. Good mixing develops with steep surface to 850 lapse rates, winds once again gusting to about 40 kts. Temperatures will trend to below normal following this system through the end of the week. Flow will become favorable for some lake effect snow showers in Northern New York on Wednesday also.

AVIATION /12Z FRIDAY THROUGH TUESDAY/. Through 06Z Saturday . Mainly BKN/OVC VFR through 12Z with cigs around 035 AGL at most terminals under diminishing west to northwesterly flow. Exception at KSLK with persistent MVFR stratus around 020 AGL. A few flurries will be possible, especially over higher terrain which will remain largely obscured. After 12Z deterioration to widespread MVFR/IFR in light snows expected at all terminals under light winds generally 5 kts or less. Light snows taper off in the 21-03Z time frame as winds trend light north/northwesterly around 5 kts and cigs lift to a mix of VFR and MVFR.

Outlook .

Saturday: VFR. NO SIG WX. Saturday Night: VFR. NO SIG WX. Sunday: VFR. NO SIG WX. Sunday Night: VFR. Chance RA, Chance SN. Monday: Mainly MVFR, with areas VFR possible. Likely RA, Likely SHRA. Monday Night: Mainly IFR, with areas MVFR possible. Likely SHRA, Patchy BR. Tuesday: Mainly MVFR, with areas IFR possible. Chance SHRA.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
