000 FXUS61 KPBZ 261231 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 831 AM EDT TUE JUL 26 2016 .SYNOPSIS... Warm and dry weather can be expected until the approach of low pressure on Thursday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --
Minor adjustments were made based on latest surface and satellite observations this morning. The surface boundary will slowly drag southward, bringing relatively cooler dew point temperatures across the area today. The boundary is expected to stall near the PA/WV border while a weak shortwaves shifts across the southern CWA to help induce weak convection. Thus, slight to chance pops remain across the southern most zones. Temperatures will be above normal, but much less humid conditions are expected than previous several days.
