&& .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
A cold front will continue pushing southward away from the region as high pressure builds over the forecast area throughout the day. This will provide dry conditions and mostly skies areawide throughout today. Winds will remain out of the northwest blowing 5-10 knots, gusting up to 15 to 20 knots before becoming light and variable overnight. High temperatures will be in the upper 70s to mid 80s with higher elevations staying in the 60s. Overnight low temperatures will dip into the upper 50s to 60s areawide.

&& .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
-- Changed Discussion --
A weak cold front will track southeast over the forecast area throughout the day on Sunday, bringing low end PoPs (<40%) to the area. Lack of moisture aloft will keep precipitation chances at slight chance to chance with the greatest chances being for those along and west of the Alleghenies. High temperatures will get into the upper 70s to mid 80s for most while those at higher elevations stay in the 60s to low 70s. Breezy northwest winds will gust 15 to 20 knots in the afternoon before diminishing overnight. Temperatures dip into the 50s to 60s areawide Sunday night as dry conditions return. High pressure will build in over the region on Monday as winds remain out of the northwest. Most of the area is expected to be dry, but an upper level trough pivoting over the area will bring a slight chance of precipitation to those along the Alleghenies and in the southernmost portions of the area. High temperatures will be slightly cooler in the wake of the cold front with highs in the 70s (60s mountains) for most. Overnight low temperatures will fall into the 40s to 50s for most with only those in the metro areas staying in the low 60s.

&& .LONG TERM /TUESDAY THROUGH FRIDAY/...
-- Changed Discussion --
High pressure will settle over the Mid-Atlantic Tuesday and Wednesday before moving further offshore later in the week. For Tuesday, mostly sunny skies are expected with highs in the upper 70s to low 80s for most areas aside from the mountains where mid to upper 60s will be more common. A weak shortwave may approach the far western areas on Wednesday afternoon and bring a few light showers across mainly the Allegheny Front, otherwise most areas will stay dry with highs in the low to mid 80s with some areas even nearing 90 degrees. The higher terrain will be a bit cooler, in the low to mid 70s. A warmer and more moist airmass returns late in the week as high pressure scoots further offshore. A cold front approaches from the Great Lakes region Thursday into early Friday, with showers and a few isolated thunderstorms possible on Thursday and slightly better chances moving in on Friday. Highs will be in the low to mid 90s with a more apparent summertime airmass settling in for the time- being. Overall, the front passage looks to be fairly lacking of moisture but cannot rule out some precipitation with it.
