350 FXUS61 KPBZ 030023 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 723 PM EST Fri Jan 2 2026 .SYNOPSIS... Light snow chances mainly north of Pittsburgh and in the ridges Saturday night. Otherwise dry this weekend. Warmer temperatures and periodic rain chances are expected Tuesday through the end of next week. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... KEY MESSAGES: - Lingering light snow north of I-80 wanes through the afternoon - Dry and cold tonight with low temperatures in the teens --------------------------------------------------------------- 7PM Update...The current conditions show mainly high pressure in control with the exception of some flurries still flying north of Beaver County. Updated the grids to keep the mention of flurries in through the next few hours. Also freshened up the temps and dew points, the rest of the forecast is on track. Light lake-effect snow is ongoing this afternoon north of I-80 with flurries making it as far south as the Rt 422 corridor. These should wane through the remaining daytime hours as prevailing boundary-layer winds gradually shift this activity north of the area. A dry night is then forecast for the entire area as high pressure builds into the region from the west. Temperatures continue to run below seasonal levels, with lows dipping into the teens areawide by early Saturday morning. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/... KEY MESSAGES: - Light snow possible near/north of Pittsburgh and in the ridges late Saturday into Saturday night; light accumulations and minimal impact expected - Dry weather returns Sunday as a warming trend begins ---------------------------------------------------------------- Building broad surface high pressure across the central US will keep dry weather in the forecast on Saturday while temperature trends remain steady as highs reach the upper 20s. A weak passing disturbance may bring light snow to areas near and north of Pittsburgh and to the ridges of SW PA and northern WV late Saturday and Saturday night. This system will likely be moisture starved, resulting in light rates and minimal snow accumulation. Even the HREF and NBM 95th percentile snow totals both suggest a dusting to at most an inch in the ridges. Given that, impacts appear unlikely at this time. Mainly dry conditions resume on Sunday as the upper disturbance exits to the east, but a few lake-effect flurries will remain possible for the I-80 corridor as boundary-layer winds veer more northwesterly. Temperatures will remain below seasonal averages through the weekend, but a slow warming trend begin on Sunday as highs climb a few degrees warmer into the low 30s for most of the area. && .LONG TERM /MONDAY THROUGH FRIDAY/... KEY MESSAGES: - Above-normal temperatures and periodic precipitation chances throughout next week ------------------------------------------------------------------- Numerical guidance has backed off a bit on precipitation chances with a weak disturbance that crosses north of the area early Monday. There are non-zero chances for some light snow or flurries mainly north of Pittsburgh, but with little to no accumulation expected, impacts appears unlikely. Meanwhile, long-range ensembles signal a shift in the pattern early next week as the NE CONUS upper trough finally departs to the east and zonal flow develops over our region. This will allow temperatures to moderate back towards seasonal averages, and the forecast sees fairly robust warming through the week as a result. NBM means push high temperatures above freezing nearly areawide Monday afternoon and most areas near/above 50F by Thursday or Friday. Zonal flow will steer a series of weak impulses across the region throughout the week, allowing for light, non-impactful precipitation chances almost daily starting Tuesday. Given the warming trend, the predominant ptype should be rain. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... KEY MESSAGES: - Flurries/light snow north of PIT this evening - VFR returns south of I-70 tonight - VFR for most airports on Saturday ------------------------------------------------------------ A cold WNW boundary layer flow across the Great Lakes will maintain MVFR cigs and light snow/flurries generally north of a PHD-PIT-LBE line this evening. The flow is progged to veer more to the NW overnight, which could bring MVFR cigs back swd toward PIT and AGC, before backing flow Saturday morning lifts the stratocu back north. FKL and DUJ could stay MVFR much of the day Saturday as westerly flow persists. Elsewhere, expect VFR, though mid level clouds will increase ahead of the next approaching shortwave trough. This trough will likely spread light snow and patchy MVFR conditions across the area Saturday night as it crosses the Upper Ohio Valley region. Outlook... Restrictions are likely Saturday night into Sunday with the crossing shortwave trough. VFR should return Sunday and Monday under high pressure. Restriction and rain potential is expected Tuesday and Wednesday with crossing low pressure. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None.
