An update from the Connecticut Division of Emergency Management and Homeland Security:

At noon radar showed light to occasionally moderate snow falling in southern CT.  The northern edge of the light snow is now in the Middletown area.  The falling snow is melting on contact on the highways.   Some secondary roads in southern Fairfield county may start to see a coating of slush and snow over the next few hours.  Temperatures are currently in the low to mid 30’s across the state with northeast winds gusting to 20 MPH inland and 25 – 30 MPH along the coast at times.  

Here’s the latest forecast based on a blend of the GFS and NAM models.  This forecast has a good confidence level.

THIS AFTERNOON: Snow becoming moderate along the entire coast by noon.  The snow intensity in the Hartford area is forecast to become moderate between 3:00 – 5:00 PM.  Total accumulations by the start of the rush hour at 3:00 PM are forecast to range from less than 1” in the Hartford area up to 5″ along the coast.  The impact on the afternoon rush hour is expected to be minor in Northern CT and minor to moderate Southern CT.  Snowfall rates are forecast to be around 1/2″ per hour in the Hartford area and up to 1″ per hour along the coast by the end of the rush hour.  Much of the falling snow will likely melt on contact in the valleys.  Highs remaining near 30 F.  Minor coastal flooding is possible during the afternoon high tides in Western Long Island Sound around 3:00 PM.  

THIS EVENING AND OVERNIGHT: A period of moderate to heavy snow is possible between 5:00 PM and Midnight across most of the state.  The impact on travel could be moderate to major with heavy snow falling and sticking to roads after dark, especially in southern CT.  Lows in the upper 20’s.  The snow is forecast to end around daybreak on Thursday.  A minor impact to the rush hour is still possible Thursday morning.  Some power outages may occur due to the semi-wet snow.
