***Evening Update by Kurt Aaron***
The temperature will drop into the single digits overnight as high pressure moves over the state. Tuesday will start sunny but feature increasing clouds during the day. Snow and wintry mix will develop during the afternoon and continue into the evening hours. A gradual change to sleet and freezing rain will occur Tuesday night. High of 32°. The low responsible for the wintry mix will pull away Wednesday dragging a cold front over PA. The cold front will stall just to our south and help keep us cloudy Wednesday and Thursday. Also, rain showers are likely Wednesday as the temperature climbs into the middle 40s. An arctic front will move across the region Wednesday night and change the rain shower to snow showers and flurries on Thursday. The arctic air will keep the region’s afternoon temperatures in the 20s Thursday and Friday.
The weekend looks warmer with afternoon temperatures in the middle and upper 30s along with lots of clouds. The average high on March 1st, is 42°, by the end of the month it’s 53°. It would be nice to start seeing near normal temperatures as the month moves along. Unfortunately, the long-range forecast for the entire month of March forecast below average temperatures.. Lets hope the weather models are wrong!
The battle between cold air to the north and warmer air to the south intensifies in March especially with the warm air now gaining momentum and able to advance farther north. An invasion of warmer air tomorrow blowing over colder air will deliver a few hours of snow and sleet starting in the afternoon. By 9:00pm tomorrow night expect all sleet and some freezing rain accumulating into a glaze of ice . A change to all freezing rain and plain rain will occur overnight as surface temps rise above freezing. Fog will also form and last into Wednesday with rain and drizzle.
Much colder air returns by Thursday when a band of snow could spread north into our area along a stalled front.
