Summary of Next 3 Days and Thoughts on Friday/Saturday Winter Storm

Thoughts on Storm Friday:

  • Winter storm likely to occur on Friday/Saturday. Rain to impact SE while significant snow/mix is possible in the Mid-Atlantic and Northeast
  • Still too early to tell the exact track of the system. Start to narrow margin of error and potentially get into specifics on Wednesday.
  • Latest models have recently been shifting the system southward. However, some models still keep southern PA in a significant band of snow.
  • Recent cold air will help snow to stick in areas that are near the rain snow line where the heaviest snow will likely fall.
  • DC/Philly/NYC are currently in a good zone for getting significant snow, but like I said, models are still shifting the track of the storm.
  • I’ll try to keep you updated with my thoughts. Be aware of this and plan accordingly.
