AREA FORECAST DISCUSSION National Weather Service Albany NY 1246 PM EST Mon Jan 25 2021

SYNOPSIS. High pressure will keep the weather tranquil and near seasonable today. However, a warm front and associated low pressure area approaches on Tuesday. This will likely bring a period of accumulating snow to many areas into Tuesday night. Then the weather turns colder toward the second half of the week with the passage of an arctic boundary.

NEAR TERM /THROUGH TONIGHT/. As of 1245 PM EST, low clouds still persisting across far northern Hamilton County, with gradual erosion noted from the west per latest Visible satellite imagery. Elsewhere, skies remain mostly sunny. Temps have moderated into the lower/mid 20s for most areas, with some temps nearing 30 across the mid Hudson Valley. Where low clouds continue across portions of the SW Adirondacks, temps remain in the mid/upper teens.

Sunshine should mix with high clouds from southwest to northeast by mid to late afternoon. High temps should reach 25-30 for many lower elevations, perhaps approaching the freezing mark within the mid Hudson Valley, with mainly 20-25 across the southern Adirondacks and higher elevations of the eastern Catskills, southern VT/western MA, and within the central Mohawk Valley.

The high pressure area will slowly retreat to the north of the St Lawrence Valley tonight. This will allow for the storm currently impacting the Southern Plains to begin its approach. So clouds will be on the increase from south to north overnight as we will keep the region dry for now due to low level ageostrophic flow remaining from the north where drier air resides. Overnight lows will be tricky as winds will be light this evening and under minimal cloud coverage before those clouds arrive. We will undercut guidance at least a couple of degrees with single digits along and north of I90 with teens elsewhere.

SHORT TERM /TUESDAY THROUGH WEDNESDAY/. An accumulating snowfall event looks likely Tuesday into Tuesday night.

NCEP Model Suite and international guidance still differ with respect to overall impacts from pending accumulating snowfall for the region (ie QPF). Consensus suggests clouds will continue to thicken as broad isentropic lift commences through Tuesday. Low level baroclinic zone increases and translates northward across the region from late morning and into the afternoon hours. Isentropic lift 280-290K surface quickly commences with band(s) of snow tracking northward from mid- morning and into the afternoon hours. Per cross sections and BUFKIT profiles, seems the best lift will occur below the best dendritic zone along with deformation axis appears to be lining up near the I84 corridor later in the day and into the evening hours. This would suggest the flake size would be a little smaller and overall amounts to be on the lighter side. Local research of H925-H850 low level wind trajectories from the south- southwest suggest the higher QPF totals would occur into the foothills of the Dacks into northern Herkimer, Hamilton and northern Fulton Counties and the higher terrain of the southern Greens with reduced amounts into the valley locations. Per close coordination from WPC and neighboring offices, we followed a blend of the NAM/ECMWF which is rather close to both the Cobb and the Garcia Techniques . an isentropic analysis perspectives of 2-3 g/kg on the surface. So it would appear around 6" for the Dacks and southern Greens, 4-6" for the Catskills and northern Berks, and approx 2-4" elsewhere. If a mesoscale band where to evolve, it would be quite elongated East-West band and per the 06Z/HRRR, this would line up in the vicinity of the I90 corridor (confidence not that high yet as main H850-700 low tracks north of this region and is forecast to weaken Tuesday evening). Regardless of solution, a period of light to perhaps moderate snow will impact the region later Tuesday into Tuesday night to make for a impactful traveling conditions. Headlines will likely be issued for portions of the CWA later today. High temperatures mainly into the 20s Tuesday and overnight lows into Wednesday morning ranging from the teens across the higher terrain to mid 20s for valley locations south of Glens Falls.

Snow is expected to tapper back toward sunrise Wednesday with lingering flurries anticipated during the daylight hours as weakening surface low reflection translates across the region. Under considerable cloud coverage, and a slightly positive modification to the boundary layer temperatures, highs into the lower 30s for the mid Hudson Valley and portions of Litchfield County to mid-upr 20s elsewhere.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. A strong upper level disturbance and associated wave of low pressure will be passing across the mid-Atlantic States for Wed night into Thursday. This storm looks too far south to have much of an impact on our area, but can't rule out a few light snow showers for eastern areas, as the upper level trough axis swings across the area. Otherwise, plenty of lingering low-level moisture trapped beneath an inversion will keep it fairly cloudy. Temps look fairly seasonable with lows in the mid teens to mid 20s and highs in the 20s to low 30s.

A closed off disturbance at 500 hpa will be dropping from southern Canada towards the Northeast for Thursday night into Friday. Upper level heights will be very low and 850 hpa temps will be dropping to their coldest values of the winter so far (as low as -23 C). While it looks dry, as any precip should be east of the region, it will be very cold with gusty northwest winds. Temps will fall into the single digits on Thursday night and probably won't be rising too much for Friday. We currently have highs in the mid teens for valley areas and it's possible this could be a little generous. Wind chill values will likely be below zero for most of the day Friday with a partly to mostly cloudy sky.

Over the weekend, some moderation is expected as the upper level low moves away and heights slowly rise. It still will be rather cold for Saturday with highs in the teens to low 20s. By Sunday, temps may reach back into the mid to upper 20s for highs. While Saturday should be dry, there is the chance for some light snow by later on Sunday as the next system approaches, although the exact timing of this system is still uncertain, as it could hold off until Sunday night or Monday. At this point, this next storm looks to be a storm system that approaches from the west and then reforms near or south of the area, so snow or snow going to a wintry mix looks to be the main p-type with this system.

AVIATION /18Z MONDAY THROUGH SATURDAY/. High pressure will bring clear skies and seasonably cold weather with VFR conditions to the area through this evening. High clouds will overspread the area late tonight as low pressure approaches from the west. Snow will begin tomorrow afternoon across the TAF sites, with conditions rapidly decreasing from VFR cigs and Vsbys during the late morning to IFR conditions by mid-afternoon. Winds will be variable at less than 10 kts through Tuesday.

Outlook .

Tuesday Night: High Operational Impact. Likely SN. Wednesday: Moderate Operational Impact. Chance of SN. Wednesday Night: Low Operational Impact. Slight Chance of SHSN. Thursday:No Operational Impact. NO SIG WX. Thursday Night: No Operational Impact. NO SIG WX. Friday: Low Operational Impact. Breezy. NO SIG WX. Friday Night: No Operational Impact. NO SIG WX. Saturday: No Operational Impact. NO SIG WX.

HYDROLOGY. No widespread hydrological issues are expected for the upcoming week. While accumulating snowfall is expected Tuesday into Tuesday night, and perhaps the upcoming weekend, this will have little impact on area rivers.

Unseasonably cold temperatures will persist through much of the week ahead. Cold air will continue to support river and lake ice development this week.
