...Significant storm system to affect southeast Wyoming and the
western Nebraska Panhandle Thursday night and Friday...

A strong low pressure system will develop over eastern Colorado
late Thursday and track south of the area through Friday. Ahead of
this system, rain will develop over areas west of the Laramie
Range on Thursday and spread eastward through Thursday night.

At the same time, colder air will begin to filter into the area
from the north which will begin changing the rain to snow over the
mountains during the day on Thursday. The rain will begin changing
to snow at lower elevations over southeast Wyoming Thursday night
and possibly into portions of the western Nebraska Panhandle on
Friday morning.

There is the potential for a significant winter storm Thursday
night and Friday especially south of a line from Rawlins to
Wheatland to Scottsbluff. At this time there is still much
uncertainty as to the exact timing and track of the system which
will greatly affect potential snowfall amounts. Disruptions to
travel especially along Interstate 80 and Interstate 25 in
Southeast Wyoming are possible. Those living in or planning travel
through southeast Wyoming and the western Nebraska Panhandle
Thursday or Friday should monitor the latest forecasts on this
developing weather situation.
