Super Bowl Sunday Snowfall Forecast

 The second significant snowstorm within a week impacts Connecticut Super Bowl Sunday as a potent coastal storm looks to track close enough to the coast to bring a band of moderate-to-heavy snowfall across the state Sunday. This will be a fast moving storm which will preclude the potential for even higher amounts. 

Forecast models are showing an intense band of heavy snow traversing the state from late Sunday morning through late afternoon. Snowfall rates once again could approach 2 to 3 inches per hour during this window:


There is pretty strong agreement in the 850mb low to track just south and east of Connecticut with very strong 60+ knots of inflow feeding moisture into the storm. This track is perfect for heavy snow across the state. Should also be noted the 700mb low tracks just south and east of Connecticut as well:


What to Expect:

  • Snow starts 4:00 - 7:00 AM Sunday morning and quickly becomes moderate-to-heavy through mid-to-late morning.
  • Heaviest of the snow falls in a window between 11:00 AM - 3:00 PM EST. Snowfall rates of 2 to 3'' per hour at times in this window. 
  • Wind gusts 25 to 35 mph along the coast
  • Snow rapidly tapers off by late afternoon and is out by evening. 
  • Lowest confidence: Northwestern Connecticut
