Updated Snow Accumulation Estimates, Timing Of Storm: CT Weather

CONNECTICUT — In an evening update, the National Weather Service has released new estimates for snow, ice and rain for the Sunday and Monday storm. The latest news centers on the fact that the storm is expected to trend warmer, which will keep snow totals down a bit, especially along the coast.

Some areas, i.e. Litchfield County could still see near a foot of snow while the rest of northern Connecticut and inland sections of Southern Connecticut may see several inches of snow but sleet and ice is expected to mix in.

Along the immediate coastline, it will mainly be a mixed precipitation, rain event with very minor snow accumulation.

Original story: CONNECTICUT — If you need to get somewhere in Connecticut on Sunday, you'll want to do it by noon, which is when it should be snowing everywhere in the state. And there will be no real let up from this very slow moving storm, which will impact the weather for Sunday, Monday and early Tuesday.

This is an unusually long duration storm. A Winter Storm Watch is in effect for Hartford, Tolland, Litchfield counties, and inland sections of Fairfield, New Haven, and Middlesex counties. A Hazardous Weather Outlook is in effect for the coast of Fairfield, New Haven, and Middlesex counties along with New London and Windham counties.

Some parts of Connecticut may see up to a foot or more of heavy, wet snow, but also of great concern is the ice that is predicted to mix in on Sunday night and Monday morning, especially for areas away from the immediate coast.

The National Weather Service says, "Precipitation begins as snow everywhere in the region Sunday morning before transitioning to rain along coastal areas Sunday afternoon into Sunday night. Meanwhile, the interior will transition to a wintry mix. For Monday, the initial wintry mix will change back over to snow for the interior with the coast going from rain to back to snow as well late in the day. Snow will linger Monday night before eventually tapering off by early Tuesday.

"There is potential for significant snow accumulations across the interior with light snow accumulations possible towards the coast within the Sunday through Monday night timeframe. Some light ice accumulations are possible as well. Temperatures are expected to remain several degrees below normal for much of the time period."
