000 FXUS61 KPBZ 200431 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 1231 AM EDT Fri Apr 20 2018 .SYNOPSIS... Dry weather is expected through early next week along with more seasonal temperatures. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... Main change just before midnight was to decrease sky cover overnight as the lower level start to dry out. Mainly cosmetic changes otherwise. Previous discussion... Dry conditions expected through the night as high pressure builds back in over the the area. Latest soundings indicate lower levels to remain mixed overnight...so expect gusty winds to be maintained for much of the night. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM 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 THURSDAY/... Ridging will continue to build over the forecast area through early next week...maintaining dry conditions and a warming trend in temperatures. There is still below average model consensus in regards to timing the arrival of a southern stream low and it`s eventual phasing with a northern stream system. Minor adjustments in timing were largely made using latest ensemble guidance. && .AVIATION /06Z FRIDAY THROUGH TUESDAY/...
