Conditions are highly variable at present. VFR conditions are present from PIT on southwest, with IFR/LIFR noted to the east. Expect most terminals to settle back towards MVFR/IFR with time in the wraparound moisture, with continuing pockets of LIFR in drizzle and snow. Precipitation coverage will taper with time, with some rain and snow showers continuing along the ridges into midday. Ceilings may lift to MVFR for a time before sinking back towards IFR after sunset. North to northwest winds should remain mostly 10 knots or less. .OUTLOOK... Periodic restrictions are expected late Wed through Sat with a crossing cold front and subsequent upper troughing.
