Another Significant Snow Event On The Way ! Very Cold Temps To Follow For The Weekend !

Tuesday 7:00 PM

This is my preliminary call for Thursday night into Friday. I'll do a more detailed call and Discussion on Wednesday Evening with a snowfall Map.

This upcoming system with be moving in from the TN Valley During Thursday night. This storm will take a favorable track just to our south an exit off the Delmarva Coast on Friday morning. As this system reaches the coast it will intensify and move northeast. Once again, Upper level energy and a trough approaching from the Ohio Valley, will help energize the surface low, once it reaches the coast. Light Snow will spread into the Delaware Valley later Thursday evening and continue into much of Friday morning, before tapering off the flurries during the afternoon.

A period of moderate to heavy snow is possible from later Thursday night into the morning hours on Friday, which will make for a messy and nasty morning commute. This heavier snow will most likely occur between 4:00 AM and 10:00 AM Friday morning.

I'm forecasting a general 4"-8" of snow accumulation across the entire Delaware Valley. Along the coastal sections of SE NJ and Southern DE, some rain could mix in for a few hours, and I'm thinking 2"-4" of accumulation in these southern most and coastal areas.

Behind this storm very cold air will follow for the weekend. Expect dry conditions for the weekend with highs remaining in the 20's for both Saturday and Sunday and overnight lows near 10.

I'll issue my final call and thoughts on Wednesday evening with a snowfall map.

Take Care,
