AREA FORECAST DISCUSSION National Weather Service Albany NY 406 AM EST Sat Feb 27 2021

SYNOPSIS. A storm system will push across the area today with snow and a wintry mix changing to rain. Drier weather returns tonight as high pressure builds into the area. Another system will move across the region later Sunday with periods of rain and perhaps a wintry mix across the higher terrain. Temperatures this weekend will run slightly above normal.

NEAR TERM /UNTIL 6 PM THIS EVENING/. A Winter Weather Advisory is in effect for western Ulster and Greene counties until 11 AM EST .

A Winter Weather Advisory is in effect for the southern Adirondacks and the southern Green Mountains of southern Vermont until 2 PM EST .

An area of low pressure will lift northeastward from the Great Lakes into Quebec today as a warm front lifts northward across New York and western New England. Lift along the front will spread precipitation across our area. Surface temperatures widely vary across the region with some teens and lower 20s in some of the higher terrain areas to the upper 20s to mid-30s across valley areas. Precipitation in most areas will start out as snow early this morning.

Forecast soundings suggest that cold air will become trapped near and just above the surface across some areas this morning while air aloft rises above freezing. This will allow snow to mix with and change over to sleet and/or freezing rain for a time. This will be most common across the higher terrain areas (eastern Catskills, southern Adirondacks and southern Green Mountains) where a deep snowpack remains in place (around 12 to 24 inches). As a result, Winter Weather Advisories were issued for these areas. Expect snowfall amounts to generally range from 1 to 3 inches with flat ice amounts up to a tenth of an inch.

Outside of the Winter Weather Advisory areas, less than one inch of snow is expected this morning.

Most of the precipitation will depart to our east during the afternoon with just some lingering scattered showers possible until sunset. Total QPF amounts will range from 0.25 to 0.50 of an inch across the area, except the Capital District to the Mohawk and Schoharie valleys where precipitation shadowing is expected to occur (generally 0.10 of an inch or less expected here).

High temperatures this afternoon will range from the mid- to upper 30s across some higher terrain areas to the mid-40s in the valleys.

SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/. As this system departs to the east, high pressure will build into the region tonight. Clouds will partially clear with winds going calm. Despite weak cold air advection behind this system, temperatures could fall quickly later tonight as suggested by MOS guidance, especially if prolonged clearing occurs. Expect lows in most areas to bottom out in the 20s.

On Sunday, the high will move off to the east as the next system approaches from the south and west. This feature contains both a northern stream feature (tracking from the Great Lakes toward Hudson Bay) and southern stream feature (tracking from the Ohio Valley to the mid-Atlantic coast). Despite the split flow, some precipitation is expected to spread across the region as another warm front lifts through our region. Guidance continues to slow on the arrival of this precipitation, not bring much in until the afternoon hours from southwest to northeast. So, POPs were adjusted accordingly. Temperatures should rise above freezing across most areas before the precipitation starts so we are looking at a mainly rain event. However, should any cold air remain trapped (especially in the higher terrain areas), some light snow, sleet or freezing rain will be possible once again. High temperatures will reach the upper 30s across some higher terrain areas to the lower and mid-40s in the valleys.

We will remain in the warm sector for much of Sunday night before the cold front pushes from west to east toward daybreak Monday. So, occasional rain showers are expected across the area. As colder air arrives along and in the wake of the front, precipitation may mix with and/or change to snow, especially across higher terrain areas, before ending. Low temperatures will drop into the upper 20s in the higher terrain to the mid- 30s in the valleys.

LONG TERM /MONDAY THROUGH FRIDAY/. The extended forecast will feature an arctic cold frontal passage Monday afternoon into the evening with a threat of isolated to scattered snow showers and snow squalls. Blustery and very cold conditions will follow in the wake of the boundary. High pressure ridges in Tuesday into Wednesday with fair and dry weather with temperatures rising back to normal or slightly above normal readings for the mid week. A cold front approaches late Thu into Friday with isolated rain or snow showers and temperatures settling back to early March readings.

Mon-Mon Night . A pair of cold fronts will impact the region. The first boundary goes through in the morning into the early afternoon. A strong mid and upper level short-wave with an arctic cold front moves across NY and New England in the late afternoon into early evening. The Snow Squall Parameter based on the 0-2 km RH, mean wind speed, and potential instability (theta-e decreasing with height) is greatest from the Capital Region and the Berkshires north and west on the NAM and to an extent the GFS. There is also some instability with the steepening lapse rates. Isolated to scattered snow squalls are possible especially in late afternoon into the early evening. The timing of the front is faster on the NAM compared to the GFS. We will continue to mention this possible threat in the HWO. Snow amounts will likely range from a few tenths to an inch or so with any snow showers or squalls. The threat should diminish shortly before or just after midnight. It will become blustery and very cold with west to northwest winds of 15-25 mph with some gusts 30-45 mph. A wind advisory may be needed later is more frequent gusts of 46-57 mph look probable. H850 temps plunge to -24C to -29C from northwest to southeast by Tues morning on the GFS. Wind chills may reach advisory levels in the southern Adirondacks around -20F with zero to 15 below zero readings over the rest of the region.

Highs on Monday will be in the upper 30s to mid 40s in the valleys with a few upper 40s over the mid Hudson Valley into NW CT, and upper 20s to mid/upper 30s over the higher terrain. The sharp drop in temps may also cause a flash freeze situation in some locations. Lows Monday night will be zero to 5 below over the southern Dacks, and single digits to lower to mid teens over the rest of the forecast area.

Tuesday-Wednesday night . Blustery and cold conditions will continue on Tuesday in the wake of the front. Temps will run below normal Tuesday by 10-15 degrees. Highs will only be in the teens to lower 20s over the mtns, and mid 20s to lower 30s in the valley areas. High pressure will build in from the OH Valley and lower Great Lakes Region to the Mid Atlantic Coast during the afternoon. The winds will subside towards nightfall. The mid and upper level flow becomes less amplified Tue night. Another cold night will be on tap with lows mainly in the single digits and teens. The sfc anticyclone moves off the coast with warm advection occurring into Wednesday. Some mid and high clouds may increase during the day and there is a small threat of an isolated sprinkle or shower southeast of the Capital Region, as the latest 00Z GFS/ECMWF and the majority of the Ensembles have any coastal system passing well to the south. Highs on Wed will be more seasonable with 30s over the mtns and upper 30s to mid 40s over the hills and mtns. Lows will be mainly in the 20s.

Thursday into Friday . The southern stream coastal wave passes southeast of the forecast area. The mid and upper level trough amplifies over the northeast. Temps will continue to be normal to slightly above normal on Thu. A short-wave in the northwest flow and a moisture starved cold front may move through Thu night into Friday. A slight chance of rain/snow showers was placed in the gridded forecast. Temps may cool down to seasonable values to close the week.

AVIATION /09Z SATURDAY THROUGH WEDNESDAY/. A low pressure system approaching from the Great Lakes Region and warm front will bring precipitation back into eastern NY and western New England this morning. The precipitation will begin as snow and transition to rain during the late morning into the early afternoon, as warmer air moves in at the surface. An occluded front will move through in the late afternoon into the early evening with drier conditions returning.

VFR conditions will quickly lower to MVFR/IFR levels between 08Z-12Z at KPOU/KPSF/KALB/KGFL with snow initially overspreading the region from southwest to northeast. Initially, the vsbys will lower IFR levels with low MVFR cigs in the 1.0-2.5 kft AGL range.

Expect the pcpn to change to rain quickly at KPOU by about 13Z/SAT, and then 15Z/SAT at KALB. Some rain may start to mix with snow at KPSF between 14Z-18Z/SAT. Further north, KGFL will remain snow the longest but will start to mix with some sleet and rain between 16Z-18Z/SAT. The precipitation will lighten and be plain rain or drizzle in the afternoon, but in the deeper moisture, widespread IFR conditions could develop with lower cigs and IFR/MVFR vsbys. Also, some melting snowpack will contribute to the lower vsbys.

Once the occluded front moves through between 22Z/SAT-01Z SUN, expect the cigs/vsbys to improve to MVFR levels and steady further improvement to VFR levels is expected prior to midnight.

The winds will be light to calm early this morning, except at KALB/KPSF where south to southeast winds will pick up at 5-10 knots. The southerly winds will increase after 12Z/SAT at 8 to 15 kts through the late morning into the afternoon with some gusts 20-25 kts at KALB/KPSF. The winds will shift to southwest to west at 8-12 kts in the late afternoon into the evening.

LLWS will be possible, as 2 kft winds will be 35-50 kts from a south/southeast direction between 09Z-18Z/SAT. LLWS was kept in all the TAF sites during this time frame.

Outlook .

Sunday Night: High Operational Impact. Likely SHRA. Monday: Low Operational Impact. Breezy. NO SIG WX. Monday Night: Moderate Operational Impact. Windy With Gusts To 34 kts. Chance of SHSN. Tuesday: Low Operational Impact. Breezy. NO SIG WX. Tuesday Night: No Operational Impact. NO SIG WX. Wednesday: No Operational Impact. NO SIG WX. Wednesday Night: No Operational Impact. NO SIG WX. Thursday: No Operational Impact. NO SIG WX.

HYDROLOGY. No major hydrologic issues are foreseen through the middle of next week.

Some melting and sublimation of the snowpack in the valleys is expected during the day time over the next several days. NERFC forecasts show minor up and down changes in river flows due to the diurnal freeze/thaw cycle. River ice is not expected to break up over the next several days.

Two separate systems will move across the region this weekend. The first on Saturday will bring snow and a wintry mix which will change to rain. The second on Sunday will bring mainly rain. Total QPF amounts for the Saturday system will range from 0.25 to 0.50 of an inch for most of the region, except generally less than 0.10 of an inch across the Capital District and Mohawk and Schoharie valleys. Total QPF for the Sunday system will range from 0.10 to 0.30 of an inch.

A strong cold front with snow showers is expected to move through later Monday through Monday night. Much colder air returns Monday night and Tuesday.
