Area Forecast Discussion
National Weather Service Grand Junction CO
1154 AM MDT SUN JUL 24 2016

.SHORT TERM...(Today through Monday)
Issued at 236 AM MDT Sun Jul 24 2016

A weak wave is currently moving over the Utah and Colorado border allowing
some lightning strikes and light showers to form. Outside of this
wave, a few showers formed along the Continental Divide but precip
amounts remained low.

Water vapor imagery shows plenty of drying over the Great Basin and
the models continue to pick up on this drying pattern with
forecast PWATs continuing to lower. Swamp cooler users should
rejoice as they will slowly become more efficient. Despite
atmospheric moisture decreasing somewhat, we can still expect
showers and thunderstorms to form this afternoon as heating will
work on the remaining moisture. Higher elevations look favored at
the moment with the Roan Tavaputs and Book Cliffs along with the
San Juans being favored. Some gusty winds along with occasional
heavy rainers can be expected from the stronger cells. Expect
similar conditions Monday though coverage will continue to
decrease. Temperatures will remain on the warm side both today and
tomorrow with some valleys reaching triple digits this afternoon.

.LONG TERM...(Monday through Saturday)
Issued at 312 PM MDT Sat Jul 23 2016

The dry trend will continue through the workweek as a ridge of
high pressure keeps the main plume of moisture to our south. With
isolated-scattered late-day showers and thunderstorms confined to
the higher terrain and across the south. High temperatures will
will run 5-10 degrees above normal through the period.
