Tonight's precipitation event will feature a rain changing to snow scenario through the region. Light rain and/or a mix of rain and snow will move in over the next few hours, changing over completely to snow from northwest to southeast through the Delaware Valley with the potential for one to three inches of snow north and west of the city...and around an inch of snow at the Airport and across immediate suburban South Jersey. Cold air will be a touch slow to march into the city...and if the cold air march were a bit faster we'd see a bit better snowfall results with this particular system. As such, precipitation will taper off during the morning hours from southwest to northeast, with scattered snow showers around through the afternoon with the cold front pushing in from the west. We're projecting generally 1-3" for the city and northwest...in general, the city likely picks up around an inch whereas the best chances for 3" will fall in the Pennsylvania suburban counties. We'll also have more information coming up later on this evening.
I would not be surprised if there was a "midnight high" at the Airport tomorrow as temperatures are starting to inch downward this evening, with the city itself probably around 40 at Midnight. Most of the day will be spent in the 30's tomorrow regardless of when the high does ultimately occur, a colder day than today, as colder air inches in from the west. Winds will pick up from the north and northwest in the afternoon, gusting to 25 miles per hour Saturday evening and overnight as colder air hits en masse from the west. Saturday night shapes up as the coldest night of the upcoming cold shot as lows in the north and west suburbs drop into the teens, with low 20's at the Airport.
