Winter acted like it was supposed to Thursday and early Friday, dropping 5 to 7 inches of wind-whipped snow on Fairfield and the rest of southwestern Connecticut.

Schools were closed, and town offices and the Fairfield Public Library opened later than usual.

What was not so typical -- at least for winters in these parts -- is the bone-chilling temperatures the storm left in its wake today and overnight into tomorrow.

The National Weather Service warned that record low temperatures are possible over the next two days, with wind-chill values well below zero.

The combination of temperatures ranging from the single digits to 15 degrees, with northwest winds 15 to 20 mph, gusting up to 30 to 35 mph, can produce winds chills below zero that could cause frost bite or hypothermia for anyone exposed to the cold, the NWS warns.

The extreme cold is expected to ease Saturday with temperatures hitting a high in the mid-20s, and on Sunday -- although a mix of rain and snow is possible -- the temperature could rise to about 40 degrees.
