550 FXUS61 KPBZ 310205 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 905 PM EST Tue Dec 30 2025 .SYNOPSIS... Banded snow showers continue into the afternoon today, slowly shifting northward and losing organization. Another shot of lighter intensity snow occurs overnight tonight with light accumulations. A further shot of snow and possible squalls occurs Wednesday afternoon continuing into the early morning hours of Thursday. Breezy and cold conditions stay with us into the new year. && .NEAR TERM /UNTIL 7 AM WEDNESDAY MORNING/... KEY MESSAGES: - Another quick push of light snow overnight, with light accumulations --------------------------------------------------------------- Snow showers can linger longer and possibly through the night along and north of the I-80 corridor closer to the lake influence. Another shortwave builds through the flow and rounds the base of the trough again overnight increasing the chance for snow. This snowfall is expected to be a lighter intensity than the banded snow showers we saw today. As such accumulations are expected to range from a coating to an inch or so tonight through the early morning hours of Wednesday. && .SHORT TERM /7 AM WEDNESDAY MORNING THROUGH THURSDAY/... KEY MESSAGES: - Snow New Years Eve into New Years Day; Winter Storm Warnings and Advisories in effect for portions of the region - Cold conditions continue ---------------------------------------------------------------- Snow will likely be ongoing early Wednesday morning as another shortwave crosses the region. Snowfall rates will likely with 95th percentile hourly amounts max out at 0.4" A brief lull in snowfall is possible late morning / early afternoon, before a digging trough and associated front begins to impact the region. This will return widespread snow to the region as the strong front crosses New Year's Eve into early New Year's Day. A Winter Storm Warning has been issued that runs from early afternoon until mid Thursday morning for the ridges of WV and PA where totals of six to eight inches are possible due to enhanced orographic lift. Elsewhere, snowfall amounts of two to four inches are expected in general along with some locally higher amounts. Model guidance indicates rapidly moving snow bands with periods of enhanced frontogenesis, and very high snow squall parameter rates along the front. With this and the less than ideal timing (roughly 7PM to 2AM), along with the overall snow forecast in general in the lower elevations, with this and the less than ideal timing (roughly 7PM to 2AM), a Winter Weather Advisory has been issued for the same period as the Warning. Advancing dry air from the Midwest will likely decrease snow intensity just before dawn on New Years Day. Quieter conditions look promising New Years afternoon and evening with zonal flow. Below-average temperatures will continue during this forecast time period. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... KEY MESSAGES: - Mostly quiet conditions Thursday night into Friday - Cold continues - Confidence remains high that the weekend will be free of winter weather impacts ------------------------------------------------------------------- Long-range model guidance favors generally quiet weather from Friday through Monday. A few isolated snow showers are possible Friday morning near I-80 corridor, through impacts are not expected. Multiple models indicate an elongated trough persisting over the weekend, which will keep temperatures below average while a large-scale ridge builds over the Rocky Mountains. && .AVIATION /02Z WEDNESDAY THROUGH SUNDAY/... KEY MESSAGES: - VFR this evening everywhere except I-80 corridor; cigs deteriorate to MVFR overnight with return of light snow - Overnight snow tapers off Wednesday morning before a heavier round of snow and worsening restrictions move in Wednesday afternoon and evening ------------------------------------------------------------ Ongoing snow shower activity is weakening and shifting north, a trend that will continue over the next few hours as low-end VFR cigs prevail everywhere except along/north of I-80. Widespread MVFR cigs return overnight as a passing disturbance brings another round of light snow to all area terminals, with minor additional accumulations through sunrise Wednesday. Snow tapers off again Wednesday morning but MVFR cigs continue through the afternoon. A stronger disturbance brings heavier snow (along with the potential for snow squalls/bands) and deteriorating cigs/vis mainly after 21z, though light snow and minor restrictions to visibilities could return as early as 18z. Westerly winds relax somewhat overnight, potentially losing the gusts but holding around 7-10 knots sustained. Gusts return during the day Wednesday, especially with the onset of snow in the afternoon and evening. Outlook... Restrictions continue through Wednesday night with occasional snow under upper troughing and cold W-NW flow. High pressure brings VFR conditions and dry weather back to the area Thursday and Friday except for FKL/DUJ where minor restrictions could linger through the end of the week due to passing lake-effect snow showers. && .PBZ WATCHES/WARNINGS/ADVISORIES...
