As the storm center passes after 9-11 p.m., cold air from the north will be dragged south into CT. Temperatures will drop some 20 degrees within the next several hours.
A switch over from snow to sleet and maybe even some snow inland will occur after 3 a.m. Thursday Morning. Coating to an inch is expected statewide CT other than the immediate shoreline.
Very possible for school delays on Thursday as temps will dip well below freezing by the time most of us wake up. Very possible for a flash freeze, many untreated roads will be slick.
As far as the day on Thursday is concerned, the precip is done by 12 p.m. on Thursday but temperatures will be maxed out in the mid to lower 20’s with winds from the NW gusting at 40 MPH which will make it feel like the single digits.
