A strong pacific system will spread snow across the high country,

mountains near and north of Rabbit Ears Pass, with 6 to 18 inches
over Rocky Mountain National Park and 6 to 12 inches over the
mountains near the I-70 corridor. The foothills and high valleys
will likely only recieve 1 to 4 inches. The snow will diminish
quickly after midnight, but light flurries will likely last until

Across the plains, strong west to southwesterly winds will
continue through the afternoon gusting to 25 mph, then switching
to northwesterly behind a strong cold front early this evening
with gusts near 40 mph possible. Light rain showers will spread
across ahead of the front, mixing with snow after 8 PM, clearing
out just after midnight. Accumulations of less than half an inch
is expected, and will likely only stick to grassy surfaces.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Dry and warmer conditions will return over the weekend with
decreasing winds by Saturday afternoon. Gusty winds will increase
over the mountains Sunday night with speeds up to 50 mph
possible. There will be another chance for snow in the mountains
on Monday night and then cooler all areas on Tuesday as a weak
