SYNOPSIS:

Snow is still falling over the area this evening and will continue into the night.  Snowfall will taper off through Tuesday morning.

IMPACTS: Tonight through Tuesday Morning

  • Slick and hazardous roads.
  • Severely reduced visibility at times from snow and blowing snow.

...SUMMARY...

A strong jet streak pushed down into Wyoming on Wednesday, with the
right exit region situated over the area for several hours from
Wednesday morning into Wednesday evening. This allowed for the
strong jet streak wind to mix down to the surface for several
locations. High Wind Warnings were issued and verified in the Cody
Foothills, Absaroka Mountains, and Natrona County. Some local
terrain effects resulted in high wind at Buffalo Wednesday evening
as the jet streak slid east. There were reports of loose objects
getting blown around and some objects being blown over, but there
was no major structural damage or downed trees reported.
