The heaviest snow should be on Thursday morning. Snow could linger into Friday morning, although it should be lighter by then. Temperatures should be in the upper 20s when the storm arrives, rising into the low 30s on Thursday afternoon.

Icing should be a major concern in the Southeast. It is a slow moving storm, which is while the Winter Storm Warning for southwestern Connecticut will be in effect for 18 hours. Highest amounts in Litchfield County In Connecticut, the storm could drop more than a foot of snow in northwestern Connecticut, where it could remain all snow. Forecasters say snow could fall at the rate of 1 to 2 inches an hour in Litchfield County. As with most nor\u2019easters, southeastern Connecticut (near New London) is likely to get the least snow. Areas such as Shelton should pick up considerable amounts of snow, with totals increasing the longer that temperatures remain below freezing.

The NWS also has issued a Coastal Flood Statement, indicating that \u201cminor coastal flooding\u201d is possible late Thursday due to high winds and elevated tides.
