Heavy snow fell throughout the day Sunday, dumping more than a foot in most of Connecticut, with more to come.

The snow started around 8 a.m. and gained intensity in the afternoon, falling at a rate of 2-3″ per hour. It quickly coated roads and made travel treacherous on state roads.

Gov. Ned Lamont implemented a commercial vehicle travel ban on Connecticut highways at 12 p.m. That remains in effect until further notice.

Along the shoreline, snow is mixing with sleet, but inland it is expected to remain all snow.

The heavy snow and sleet will taper off after 10 p.m. Sunday, and there will be intermittent snow and sleet through the overnight. It should be mainly light through the early morning.

A period of snow will redevelop mid-morning and areas could see an additional 1-3″ of fluffy snow, especially in northern Connecticut.

Total snowfall in many towns will be near 18″ by the time it comes to an end. Locally higher totals are possible in places where it stays all snow. The shoreline will end the storm with a foot or possibly a bit more.

Temperatures remain cold overnight and will be in the 20s on Monday.
