A trough of low pressure will shift eastward across the region today. A cold west to northwest flow across the area will produce scattered snow showers today. An area of open water has formed on Lake Erie, and this will help to contribute some moisture across the snow belt areas today, enhancing the snow showers.
Tonight and Tuesday, a weak disturbance will move through the trough and produce widespread light snow across the area, however, some lake enhancement will be possible across the snow belt. Snow accumulations today through Tuesday will be light with a dusting to an inch expected at most locations with 1 to 3 inches possible across the snow belt.
Arctic high pressure will settle across the region through mid week with temperatures averaging well below normal. Scattered snow showers will continue on Wednesday, especially across the snow belt.
