Snow Squall Timeline This Evening And Storm Next Week

Snow Squall Timeline This Evening And Storm Next Week

February 12- There will be a lot of weather action on the way over the next 3 to 5 days. As I write this, wind warning an wind chill advisories are being posted. Even the rare Ice Accretion Advisory around the Chesapeake Bay for freezing spray very far south.  But I want to focus on our evening event. A burst of snow will pass through central Maryland and southern Pennsylvania that is worth the attention. At times this may be moderate to heavy, and with temperatures in the mid 20s, everything will stick.  Here is a quick radar simulation timeline to show the progress as it develops east of the mountains and even impacts Delmarva to the beaches overnight. Please see my weekend highlights and quick preview of the storm track for early next week below. FITF


  • Snow will fall for 3 to 5 hours.
  • It reaches metro Baltimore by 8 PM; Eastern Shore tonight.
  • Total: 1 to 2 inches north and west of Baltimore. Most get a dusting to 1 inch.
  • Parts of Delmarva will get over 1″
