Blizzard and Winter Storm Watch

A Blizzard Watch has been issued for Stephenson, Jo Daviess, Carroll and Whiteside Counties effective Saturday evening lasting through Sunday afternoon.

A Winter Storm Watch has been issued for Rock, Green, Walworth, Winnebago, Boone, McHenry, Ogle, Lee and DeKalb counties effective Saturday evening lasting through Sunday.

A strong low pressure system will begin to develop across the Plains tonight and move into the Sateline by Saturday evening.  A mix of rain/sleet/snow/freezing rain will be possible late tonight and early Saturday.  The storm will then begin to strengthen as it moves across the Stateline pulling in much colder air behind it bringing snowfall back to the region.  Northerly winds will likely gust in excess of 45 mph.  While snowfall amounts might not exceed 6", the very strong winds will cause blowing and drifting.  In addition, temperatures will fall quickly Sunday creating  dangerous wind chills of -25° to -10°.

Chief Meteorologist Ty Shesky will have more for you tonight on the WTVO Channel 17 News at 5pm.
