Heavy snow producing 2-3″ per hour by Wednesday evening

Forecast

A heavy, disruptive snow to hit the Midstate...

TONIGHT: Cloudy Skies, Colder. Lo 24.

WEDNESDAY: Heavy Snow Develops from South to North After 10 AM. Snow Becomes Heavy Through the Evening. 1-3″ per hour of Snow Will Fall. Hi 28.

THURSDAY: Early Morning Steady Snow, Tapering Ahead of Daybreak. Clouds Will Break Through the Morning and Afternoon. Hi 33.

Tonight will bring in the chill necessary for the record December snow we will see by Wednesday afternoon/evening. Tonight will also be dry along with Wednesday morning for any necessary pre-storm preparations.

Tomorrow morning will first see thickening clouds before a light snow develops over southern tier areas as early as 10 AM. This snow will spread northward and become steadier and heavy through the afternoon. By the evening commute we do expect very challenging driving conditions. Snow by this time will be falling quickly with 1-2″ per hour rate likely, and possibly even heavier by nightfall.

Steady and heavy snow will continue for Wednesday night. Some areas south and southeast of Harrisburg may see a few hours when sleet mixes in with wet snowflakes. By this point though a good portion of the snow will have already accumulated. Road conditions, especially secondary roadways will likely remain treacherous through early Thursday morning. Snow showers will then taper off around 4-6 AM as the storm exits east. Winds will pick up throughout Thursday as temperatures remain in the low 30s.

Calmer weather will end the work week heading into the weekend. Temperatures remain in the 30s during the day through Saturday with lows in the 20s- meaning Wednesday’s snow will hang around for a while. A few flurries or snow showers reappear in the forecast Sunday and next Tuesday, but nothing as significant as this Wednesday’s Nor’easter.
