&& .LONG TERM /TUESDAY NIGHT THROUGH MONDAY/... In the extended the heat continues through midweek...then a cooling trend to near normal highs looks likely for a few days as several fronts linger over the area and the core of hot temperatures shifts west. The upper ridge across the Southern U.S. is forecast to retrogress into the Southwestern U.S. by late in the week allowing northern stream energy to produce a weak, but persistent troffing across the northeast states. Cold front currently crossing the region is forecast to stall just south of the PA/MD border. A wave is forecast to form on the front supported by the developing upper trof, moving east through the Ohio Valley Friday and crossing PA on Saturday into Sunday. This looks to bring a prolonged period of unsettled with weather with showery conds across the state. The cloudiness will further support cooler high temperatures than recent days. Low temperatures during this period look to be several degrees above normal, especially across southern sections of the state. && .AVIATION /00Z TUESDAY THROUGH SATURDAY/...
