WESTPORT — That unfamiliar cold, white substance drifting from the skies early Saturday afternoon is a thing called snow.

A meteorological phenomenon that traditionally is part of Westport’s seasonal weather patterns, snow has been as rare as a unicorn so far this season, save for a few random flakes that melted as soon as they hit the ground.

Till now.

A light, but slippery, dusting of snow that began falling across southwestern Connecticut late Saturday morning is expected to keep coming down through early afternoon, according to the National Weather Service.

Although accumulations are forecast to be no more than one-half inch, the weather service has issued a statement warning of hazardous weather conditions in the region because “with temperatures in the 20s, untreated surfaces may become snow covered. Be prepared for the possibility of slippery roads and locally reduced visibilities, and use extra caution if traveling today.”

The daytime high temperature Saturday will remain below freezing, in the mid-to-upper 20s, dropping to an overnight low of about 20 degrees, according to the NWS.

Temperatures should rebound Sunday, and snow should be gone, as temperatures rise to the mid-40s under partly sunny skies.

But Old Man Winter is not giving up.

That’s because there is chance of snow, perhaps mixing with rain, Monday afternoon, and snow is likely to continue into Monday night with accumulations of between three to five inches possible, the weather service says.

More precipitation — in the form of rain — is possible Tuesday with daytime high temperatures in the mid-40s.
