.SHORT TERM...(Tonight through Friday night)
Issued at 236 PM MDT Thu Apr 18 2019

High pressure will dominate the weather through Friday night. A
ridge will move overhead and advect in drier conditions. As the
ridgeline moves through Friday, winds aloft will shift to the west
and gradually decrease. The ridgeline will move east of the area
late Friday night toward sunrise. High temperatures will remain
about 3 to 8 degrees above normal with near normal low
temperatures.

.LONG TERM...(Saturday through Thursday)
Issued at 236 PM MDT Thu Apr 18 2019

As the ridgeline passes to the east winds aloft will shift to the
southwest and gradually increase. A weak shortwave trough ahead of
the next significant Pacific storm will move through the area
Saturday afternoon and evening. This should bring only isolated
showers and a slight chance of thunderstorms.

Sunday will see the transition to prefrontal conditions with
southwest winds increasing significantly. Though there will be
isolated showers over ridges beneath the southwest flow, most of
the precipitation ahead of the storm will be confined to the
extreme north until Sunday evening. Then the storm center will
move through the Great Basin Sunday night and reach western CO
Monday afternoon. Precipitation will increase Sunday night and
continue through Monday. As colder air filters in the snow level
will lower to 7500 to 8500 feet late Sunday night and Monday
morning. Precipitation will remain over the Continental Divide
Tuesday then clear the area late Tuesday night and early
Wednesday morning as a ridge builds into the western U.S.
