Blech! Old Man Winter Cometh. Early.

There may be eight weeks of Fall left, but if forecasts hold, Fairfield County could be hit with as much as six inches of snow by Sunday morning.

The latest advisory from the National Weather Service calls for some 3-6" of wet snow across southern Fairfield County and surrounding areas over the weekend.

"A mixture of rain and snow develops after daybreak on Saturday, then changes to snow Saturday evening," according to forecasters. "The snow will then taper off later Saturday night."

Sustained winds of 22 to 28 mph are also expected Saturday night, with gusts of up to 47 mph.

The NWS warns of "widespread hazardous travel conditions" and "local outages … due to falling tree limbs laden with heavy, wet snow."

"Be prepared for slippery roads and limited visibilities, and use caution while driving," the service advises.
