000 FXUS61 KPBZ 191440 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 1040 AM EDT Thu Apr 19 2018 .SYNOPSIS... Snow and rain showers will plague the region today with, and in the wake of passing low pressure. Dry weather can then be expected through early next week along with more seasonal temperature. && .NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --
Snow shower coverage will significantly lessen by the afternoon as drier air quickly moves in across the region...but cold advection in northwesterly flow will likely keep widely scattered light snow/flurries going through the first part of the afternoon. Wind gusts of 20 to 30 mph on average expected through the afternoon.

&& .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/... Friday and Saturday will be cool days of improvement as surface high pressure builds under cold northwest flow. Expect highs for those days 10 to 15 degrees under the averages respectively. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... Split flow is projected over the CONUS next week with nrn stream ridging and a progressing srn stream low forecast to support dry conditions with a trend toward more seasonable warmth for the Upper Ohio. The next chance for precipitation now looks to be with the advance of that srn stream low, which may shunt sufficient moisture for some light rain by Tuesday night as it phases with a more powerful nrn stream system. Confidence in the scenario is not good given doubts about phase-timing. && .AVIATION /15Z THURSDAY THROUGH MONDAY/... Ceilings are expected to bounce between IFR and LIFR as snow showers push through with this passing trough during the late morning and ceiling levels at times drop below 500ft. As we begin to dry out throughout the day, wind gusts aloft will make their way to the surface--25 to 30 kts from the NNW. Overall improvement can be expected tonight, but MVFR stratcu will linger in the cold flow off the Lakes. OUTLOOK...General VFR may then be anticipated through early next week as high pressure builds. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$ is the U.S. government's official web portal to all federal, state and local government web resources and services.
