CT Weather: Hour-By-Hour Snow, Ice Forecast Details For Sunday

CONNECTICUT — The good news is that Sunday's rain, snow and ice event doesn't look like a big deal. There just doesn't appear to be a lot of moisture with this storm system that will impact Connecticut.

However, there is enough snow and ice forecast that it could make roads slippery tonight and Monday morning in inland and northern sections of the state.

According to the National Weather Service, areas away from the immediate coast may see 2-3 inches of snow and ice accumulation Sunday afternoon and evening. However in looking at the hour-by-hour forecast below, temperatures largely stay just above freezing in Connecticut and the chance for precipitation never hits 100 percent either.

If you plan to be out and about Sunday afternoon, it appears the best chance for wintry weather is after 4 p.m. as some very light rain showers may fall before then.

Northern CT:

Hartford, Tolland and Windham County: A winter weather advisory is in effect until 7 a.m. Monday. Additional snow accumulations of 2-3 inches and ice accumulations of a light glaze possible.

Litchfield County: A winter weather advisory is in effect from 1 p.m. until midnight. Total snow accumulations of 2 to 4 inches, with isolated 5 inch amounts.

Southern CT:

Northern Fairfield, Northern New Haven County: A winter weather advisory is in effect until midnight. Additional snow accumulations of 2-3 inches.

"Patchy freezing drizzle will continue through late this afternoon," the weather service said. "Precipitation should change back to mainly snow late this afternoon into early evening, ending the threat for freezing drizzle.

"In addition to any snow accumulation, a trace of ice accretion is possible on untreated and elevated surfaces, making for dangerous travel. Extra caution should still be used if traveling into
tonight."
