While Monday's mercury reached 55 degrees by noon, Tuesday night's low is forecast at just 10 degrees.
Partly cloudy skies Tuesday and Wednesday are expected to limit temperatures to the low to middle 20s as highs before moving into the upper 20s on Thursday. The warmer weather, however, also brings the chance of snow Thursday afternoon with an accumulation of about an inch.
Snow possibilities continue through Thursday night, with another two inches possible, before turning into a mix of snow and rain on Friday as temperatures climb to 37 degrees, fueled by south/southeast winds 10 to 15 miles per hour that will push the windchill into the teens.
Fog figures prominently into the weekend forecast, with a 60 percent chance of snow to start next week, possibly with accumulations up to three inches.
