Winter Storm Update from DESPP / DEMHS, 2:30PM 1/4/18


At 2:20 PM radar showed moderate to heavy snow falling across most of the state.   North winds are currently sustained at 25 MPH with gusts to 45 – 55 MPH at times.  Eversource and UI are reporting a total of 796 customers without power across the state.  Total snowfall currently ranges between 7 – 12 inches across the state.  The following forecast is based on a blend of the GFS, HRRR and NAM models which are in good agreement:

Rest of This Afternoon: Moderate to heavy snow at times with snowfall rates between 1” – 2”  per hour until 4:00 PM.  The snow intensity is expected to slowly taper down to light snow by 6:00 PM.  However some bands of heavier snow could persist into this evening in a few towns.  Strong winds gusting to 45 – 60 MPH at times will cause blowing and drifting of the snow and also reduce visibility to near zero at times.  The strong winds may also cause some additional power outages.  A major impact is expected for travel this afternoon with 2 – 4 inches of snow on most roads and moderate snow falling.

This Evening and Overnight: The snow is forecast to end from west to east between 6:00 – 9:00 PM with considerable blowing and drifting of snow continuing overnight.  Bitterly cold conditions are expected with lows between 0 F and 10 above and winds gusting to 30 – 40 MPH at times causing wind chills to drop to -20 F at times.

Friday and Saturday: Bitterly cold and windy with highs around 10 F and overnight lows between 0 and -10 F.  Wind chills are forecast to range from around -10 F during the days down to -20 to -30 F at night.

The Department of Emergency Services and Public Protection Division of Emergency Management and Homeland Security will continue to closely monitor this storm.  The next update will be sent out this afternoon at 5:30 PM.
