000 FXUS61 KPBZ 210501 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 101 AM EDT Sat Apr 21 2018 .SYNOPSIS... High pressure will provide dry weather through the weekend, along with a warming trend towards seasonable temperatures. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... Only cosmetic changes were made to the grids at this time, mainly to dewpoints. Forecast is on track. Previous discussion... High pressure is expected to sit just to our north and radiational cooling will be dominate with our clear skies. Patchy frost may once again form on the grass before sunrise. && .SHORT TERM /6 AM THIS MORNING THROUGH SUNDAY NIGHT/... Another clear and beautiful day is expected Saturday/Saturday night as we continue to sit under that high pressure centered in Eastern Canada. Clouds, especially to our southern areas, will be begin to form as as the upper level ridge diminishes. However, temperatures will still remain seasonable in the low to mid 60s. && .LONG TERM /MONDAY THROUGH FRIDAY/... A low pressure system that is currently propagating west from the Rockies and into the Ark/LA/MS will move north into our region Tuesday evening/Wednesday morning that will bring scattered rain showers. WPC`s QPF outlook has just under an inch of total of precipitation during this time period. Looking ahead...into Thursday and Friday...there is some consistency in the models that a few more quick moving low pressure systems will keep us mostly wet as we head into the weekend. && .AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
