Snow develops across Connecticut from southwest to northeast between roughly 3 pm-7 pm.
- Snow will be heavy for a short time (1″-2″ per hour snowfall rates). Leaving snowfall forecast unchanged for now (1″-3″ south & east of Hartford, 3″-6″ north & west), however these amounts are highly dependent on when the sleet begins to mix in. A 1 degree temperature change aloft could mean all the difference between 2″ and 6″ of snow in some places. I don’t think I’ve ever seen a forecast snowfall map that verified 100% for every town & city. There are always exceptions, as there no doubt will be with this storm.
- Snow will change to mixed precipitation tonight. All areas in the state will have changed to sleet, freezing rain or rain by midnight.
- Potential for icing problems due to freezing rain – especially across interior Fairfield & Litchfield Counties, and to a somewhat lesser extent, northern Tolland & Windham Counties. Some of these places may see 0.1″ or more of ice accretion. Temperatures will rise a bit during the night.
- Precipitation will likely become lighter after midnight.
- Areas of rain early Friday morning will change to snow in Litchfield County between 7 am-9 am and may mix with or briefly change to snow elsewhere before ending by late Friday morning. partial clearing in the afternoon, with highs in the low 40’s (upper 30’s hills).
- Winds tonight from the northeast at 10-20 mph with some higher gusts. Similar speed tomorrow, but shifting into the northwest.
