This hazardous weather outlook is for portions of western
Nebraska...east central Wyoming and southeast Wyoming.

.DAY ONE...THIS AFTERNOON AND TONIGHT

No hazardous weather is expected at this time.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

Isolated thunderstorms will be possible Thursday afternoon with
the passage of a cold front. No severe weather is expected.

A strong Pacific low pressure system will track east across the
central Rockies late Thursday into Friday. This system will bring
colder temperatures and widespread rain and snow, along with gusty
winds. There is still uncertainty in the track of the storm and
the timing of rain changing to snow, which will be a major factor
in snowfall amounts and the potential impacts. At this time, the
best chance for significant snowfall accumulations will be above
6000 feet, including the mountains and I-80 summit. If you have
travel plans across southeast Wyoming late this week, please
monitor the latest forecast information over the next couple days
for more details on this potential winter storm.
