571 FXUS61 KPBZ 290850 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 450 AM EDT Mon May 29 2017 .SYNOPSIS...
-- Changed Discussion --
Weak high pressure will keep Memorial Day mostly dry with seasonable temperatures.
-- End Changed Discussion --
&& .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
Showers associated with an exiting cold front will diminish by mid-morning as high pressure builds back in out of the west. Temperatures will be near normal. Dry conditions will be short-lived as the next shortwave transitioning through the upper trough parked over the Great lakes rounds the base of the trough and scattered showers begin to develop over the forecast area by early evening. Temperatures should be close to or just above seasonal norms.
-- End Changed Discussion --
&& .SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/...
-- Changed Discussion --
Scattered showers will continue on Tuesday as a cold front crosses the forecast area. Have opted to include mention of thunder late afternoon / early evening, however, at this time instability is progged to be marginal. Dry conditions will follow tuesday night as drier air moves in behind the front.
-- End Changed Discussion --
&& .LONG TERM /WEDNESDAY THROUGH SUNDAY/...
-- Changed Discussion --
Unsettled conditions will continue the remainder of the week with no change in the longwave pattern and shortwaves moving within the aforementioned upper trough impact the area. By next weekend, the upper pattern becomes more zonal, and a frontal boundary could stall out somewhere near or in our region. This boundary could provide more focused rainfall chances, but its placement remains in question. Temperatures will remain near or just a few degrees below normal.
