000 FXUS61 KPBZ 161802 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 202 PM EDT Mon Oct 16 2017 .SYNOPSIS... After a cool start to the week, building high pressure will result in dry and gradually warming weather through the rest of the week. && .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
A few isolated showers remain in cu field that developed with the cold advection. Tonight, high pressure building at the surface will lead to clear sky and calming winds. Temperatures will crater about 5 to 10 degrees below normals, resulting in areas of frost. Some locations could see below freezing readings, but most of these will be in the valleys of the high terrain and across the north, where the growing season has already ended. Decided to go with a Frost Advisory for the rest of the zones where the growing season remains, but is winding down.

&& .SHORT TERM /TUESDAY THROUGH THURSDAY/... High pressure will remain firmly entrenched over the area through the middle of the week, ensuring a dry forecast. After the cool start Tuesday morning, daytime temperatures will begin to moderate under mostly sunny skies. Brief ridging through Wednesday will be stunted by a system passing well to our north Thursday. This system will have little impact to our area, with only a few additional clouds as a result. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
-- Changed Discussion --
After a brief flattening of the ridge Thursday night, higher heights will build back in through the end of the week, continuing the dry and warming trend. Ridge looks to maximize over the weekend with highs slated to be well-above average. Models continue to show the next chance of rain coming with a cold front early next week.
