The rain has moved out, and most parts of Central PA saw around 1" from the steady soaking system on Sunday. Now we get back to winter as temperatures cool into the upper 20s for overnight lows. A northwesterly flow of air will keep us in the 30s for the upcoming week with numerous chances of some snowfall. Most will be small nuisance snow showers, but the best chance for some accumulating snow looks to be Thursday.
Our first chance will likely be just a few flurries on Monday. There may be a snow squall or two to the northwest of Harrisburg into the afternoon hours, but most areas will just see scattered snow flurries with a chilly breeze. On Tuesday morning there is the potential for another round of snow showers as a weak clipper races by to our north. The best chance to see snow on Tuesday morning would be in our northern counties. Any accumulation would be minimal. Conditions look calm but cold for New Years Eve celebrations.
New Years Day also looks quiet but continued cloudy, before an area of low pressure develops on Thursday. The current forecast models try and move an area of light snow into the region with the potential for accumulating snow for Central PA. The system has yet to develop and is still several days away. As we get closer to the event we'll have a better idea on potential accumulation but it does look to be all snow for us with cold air in place.
Then we see a real chill in the air by the weekend, with Friday afternoon highs stuck in the 20s, and nighttime lows in the teens.
