...WINTER WEATHER ADVISORY IS CANCELLED...

The National Weather Service in Riverton has cancelled the Winter
Weather Advisory.

Snow has changed to rain across much of the Cody Foothills this
afternoon. The rain could change back to snow late this evening,
but additional snow accumulations will be half an inch or less.
Roads should be mainly wet, but some black ice could form later
tonight, mainly over bridges, as temperatures fall to just below
freezing. Thus the winter weather advisory for the Cody Foothills
has been cancelled, but the winter weather advisory for the
Absaroka Mountains continues through midnight.
