&& .SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/... The trough axis will push through Sunday night. Northwest flow over the Great Lakes, and modest cold advection, may promote a few isolated showers overnight north of Pittsburgh. These will end by sunrise, with much drier air moving in. Monday and Tuesday will feature plenty of sunshine and comfortable conditions, as surface high pressure crosses. Below normal temperatures on Monday, will rise closer to climatology on Tuesday as the air mass modifies and mid-level heights rise. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... Dry weather continues through Wednesday with the passage of the mid-level trough axis. Humidity increases again Thursday in increasing southwesterly flow. Shower and thunderstorm chances return Thursday night ahead of the next front. The boundary passes Friday or Friday night with continued rain chances. Dry weather and seasonable temperatures are expected for the end of the period. && .AVIATION /10Z SUNDAY THROUGH THURSDAY/...
