Short term...(tonight through Friday night)
issued at 300 PM MST Thursday Feb 11 2016

High pressure centered over the Great Basin and dominating
weather across most of the western U.S. Will slow move east
tonight. The trailing edge of a weak wave riding down the eastern
periphery of this ridge will bring some high and middle level clouds
to northern and central Colorado but no precipitation is expected. Areas of
haze or fog with some low stratus clouds should return to the
Vernal area... Eagle late tonight.

Friday and Friday night the ridge over Utah flattens as a wave
works into the Pacific northwest. Upper level winds back to west
and high clouds increase. Weak warm advection may continue to
erode valley inversions...though guidance temperatures are still
expected to be too warm.

Long term...(saturday through thursday)
issued at 300 PM MST Thursday Feb 11 2016

Two open Pacific waves pass this weekend bringing gusty
winds...colder air...and some snowfall to the northern mountains.
The first wave works through the northern rockies on Saturday with
reinforced colder air Saturday night into Sunday. 700mb winds
increase from around 40kts Saturday to 50kts by Sunday under a

currently prognosticated to be in the 3-8 inch range...but wind and
blowing snow could create significant impacts. Cold advection and
snow accumulations end Sunday night into Monday.

shifts inland through Wednesday. The next stronger wave will work
