Area Forecast Discussion
National Weather Service Grand Junction CO
431 AM MDT WED MAY 25 2016

.SHORT TERM...(Today through Thursday)
Issued at 342 AM MDT Wed May 25 2016

Unsettled weather continues to our west as two areas of low
pressure, one over northern Montana and another over south
California, are connected by a trough. Much of the Intermountain
West will be affected by these systems with widespread
precipitation. As far as our forecast area is concerned, best
chances for any precipitation looks to be the eastern Uinta
mountains of Utah and extreme northern portions of western
Colorado and pops reflect this. Outside of those areas, partly
cloudy skies will be the rule with some gusty afternoon winds of
20 to 30 mph at times.

By Thursday morning, the closed low over California will have
moved to the Four Corners region as models start depicting some
light precip over higher terrain. From noon onwards, instability
will increase as will available moisture allowing more widespread
rainshowers and thunderstorms to form over higher terrain with
some cells/showers drifting into valleys as the day progresses. A
few inches of snow can`t be ruled out either especially over the
San Juans. As has been the case lately, roads will be too warm for
any accumulation.  The precip and clouds will keep high
temperatures 5 to 10 degrees cooler than normal.

.LONG TERM...(Thursday night through Tuesday)
Issued at 342 AM MDT Wed May 25 2016

The long term period looks to be unsettled as showers and storms
form each afternoon and evening as weak waves and diurnal heating
work on remaining moisture. Convection will become more organized
Sunday through Tuesday as a trough moves across the western United
States. Temperatures will be below normal through Saturday and
then hover near normal, if not a little below through Tuesday.


.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 342 AM MDT Wed May 25 2016

VFR conditions expected at all TAF sites. Gusty southwest winds of
20 to 30 mph are possible this afternoon.
