000 FXUS61 KPBZ 041357 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 857 AM EST Thu Mar 4 2021 .SYNOPSIS... Dry, but cool weather can be expected through the weekend. && .NEAR TERM /THROUGH TONIGHT/... No major changes were needed for the mid mrng update as cold advection continue to flow across the region in the wake of last nights frontal passage. Temperature is expected to be around 5 degrees below average under an amplifying eastern CONUS trough. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... Amplified upper troughing is progged to persist across Eastern North America through the weekend. Sfc high pressure building under the resulting NW flow aloft should maintain dry weather through the period, though a couple of weak troughs rotating around the low could result in some periodic increase in clouds across the Lower Great Lakes/Upper Ohio Valley region. Temperature is expected to remain about 5 to 10 degrees under the calculated normals for the weekend. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... The upper low is expected to move east Sunday. Riding should then build across the Central and Eastern CONUS through mid week, ahead of a Western CONUS trough. This should result in continued dry weather, but with a warming trend. && .AVIATION /14Z THURSDAY THROUGH MONDAY/... Sfc high pressure with nwly flow aloft will maintain a widespread MVFR stratocu deck through the majority of the TAF period. Shortwaves embedded within the flow may promote the development of a few snow showers, mainly near FKL and DUJ, with brief reductions in visibility possible. Otherwise, gusty wind to near 20kts is expected through tonight. .Outlook... Ceiling restrictions are possible with a late Friday cdfnt. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None.
