Light snow has been falling several hours across southwestern Connecticut as of 5 a.m. this President's Day holiday, but is expected to taper off by midday with accumulations ranging from 1 to 4 inches.

The slick snow cover is making driving conditions dangerous, but the traffic is expected to be much lighter than usual because most business, government offices and schools have the day off.

The snow should end by about 1 p.m., according to the National Weather Service, as daytime high temperatures rise to about 36 degrees. There is an east wind 6 to 14 mph becoming north.

There may be a chance of additional light snow overnight between midnight and 3 a.m. as temperatures plunge to a low of about 15 degrees.

Tomorrow will be sunny and cold, according to the forecast, with a high of only about 30 degrees and a north wind around 15 mph. Nighttime will be clear, with a low around 15.

Things warm up a bit Wednesday with sunny skies and a high of about 36 degrees.

Thursday should be even warmer with temperatures in the low-40s.
