Wider weather episode

A cold air mass with sub-freezing temperatures that originated from Siberia was reinforced by a major winter storm that brought a snowpack across portions of southern Illinois on the 25th. Breezy west to northwest winds with occasional gusts around 20 mph caused dangerous intervals of wind chills between -15 to locally -18 in Williamson County, IL on the 26th. Northwest portions of southern Illinois and areas south of route 13 only experienced advisory criteria with values of -9 to -14. Dangerous wind chills eventually came to an end during the early morning hours of the 27th. The one exception was in Alexander, Pulaski, and Massac County, IL where wind chills warmed above -5 the morning of the 26th due to calmer winds.
