After finally climbing out of the deep freeze and taking temperatures back into the 30s, Central PA will once again have to deal with some wintry weather in time for the Friday morning commute. A weak impulse in the atmosphere will deliver a light shot of snow, transitioning to some freezing rain showers during the Friday morning hours. The snow won't amount to more than an 1", and it will just be a light glaze of ice, but it could still cause problems Friday morning before it all changes to plain rain showers into the afternoon. To break it all down, expect light snow to develop after midnight, likely changing to freezing rain showers between 4-6 am from south to north. That freezing rain and freezing drizzle activity will last through the morning commute before it turns warm enough for just plain rain showers toward noon and into the afternoon hours.
Highs on Friday will climb into the mid 30s, allowing for most of the roads to be just fine later in the day. On Saturday temperatures climb all the way into the lower 50s. It will be accompanied by afternoon and evening rain, with an inch of rain possible by Saturday night. We will have to monitor the Susquehanna and other rivers for minor flooding concerns from the combination of ice jams along with added rain water. Sunday will still feature above-average temperatures but with partly cloudy skies.
There is some disagreement in the forecast models for next week, but for now it looks like some snow showers will be possible by Wednesday. Temperatures will be running just above average for this time of year.
