A quick moving system will continue to bring snow to the state today, clearing from north to south through the night. Several inches of snow fell overnight across the Bighorn Basin, which has since tapered off to flurries with occasional bursts of light snow. This heavier snow moved south into Central Wyoming with the cold front early this morning...snow will taper off through the afternoon across Fremont and Natrona Counties. Eventually, the front will make it into southern Wyoming where a quick inch or two of snow is possible.

As clearing takes place tonight, expect widespread fog across much of the area in addition to record lows.
