Colorado

I found this special weather statement on Weather Underground. The possibilities are alarming for folks living rough.

.
Green Mountains and Rattlesnake Range
Snow possible in the lower elevations Thursday into Friday...

A major storm system is expected to take shape mainly for Thursday
and Friday. The initial cold front will move east across the area
on Wednesday with some showers and isolated thunderstorms but the
steadier and potentially heavier precipitation likely will not
start until Thursday or Thursday night. Sharply colder air will be
ushered in with this system with quite a few areas seeing rain
changing to snow Thursday night or Friday morning. There is even a
chance of significant snowfall in the Lander foothills and possibly
even Riverton if the storm sets up right. Snowfall amounts of 4
to 8 inches are possible in the Lander foothills with 6 to 12
inches along The East Slope of the Wind River mountains with
locally heavy amounts. The Wind River basin could see 1 to 4 inches
of snow. Strong northeast winds over South Pass will cause
considerable blowing snow Thursday through Friday. Please stay tuned
for later updates on this developing major storm.
