(KTVI) - Arctic High pressure has filled in behind a potent cold front that brought us a dusting of snow Tuesday night. With clear skies tonight, lows will slip to near record levels: -3 in 1936. Gusty winds out of the northwest will drag wind chills to a dangerous level, as low as -15 in rural locations, and metro St. Louis wind chills of 0 to -10. Despite sunshine on Thursday, high temperatures will only climb to 14 to 19 degrees. A new system approaches on Thursday night with light snow possible after midnight into Friday morning. Complicating the winter pattern and briefly moderating temperatures into the mid 30’s Saturday, is the likelihood of a wintery mix of snow & sleet Friday night to sleet, freezing rain and rain Saturday to snow Saturday night into early Sunday. A new dose of cold air will follow for early next week.
