327 PM MDT SUN JUL 24 2016

.SHORT TERM...(This evening through Monday night)
Issued at 327 PM MDT Sun Jul 24 2016

As a weak 40 kt upper level jet remains over NE Utah and NW
Colorado, not much will change in the current overall pattern.
Drier air will remain across the north as clearly seen on WV
imagery, and a wetter environment will remain over SW Colorado and
extreme SE Utah. Specific humidity actually increases across SW
Colorado and SE Utah on Monday as a localized surface high
pressure feature develops over central Colorado.

Temperatures will remain slightly above normal over the next
couple of days.

.LONG TERM...(Tuesday through Sunday)
Issued at 327 PM MDT Sun Jul 24 2016

High pressure will gradually shift westward over the Great Basin
over the next week with some deviations in the flow. Weak waves
will pass at times as the upper level jet fluctuates. Drier
conditions are expected to develop Wednesday through Friday with
temperatures increasing to about 10 degrees above normal during
this time. 100 degrees will not be uncommon across the desert
valleys with mountain locations pushing into the upper 70s and low
80s for max temps. The threat of afternoon storm development
should be mainly in the San Juans and across the central Divide
from Tuesday onward.

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 327 PM MDT Sun Jul 24 2016

Isolated to scattered storms will continue through the evening
hours then decrease around sunset. Storms are expected to develop
again on Monday around 16z and mainly impact south of the I-70
corridor. Moderate rain and gusty winds to 40 mph will be possible
with storms this evening and Monday afternoon. ILS breakpoints may
be reached with potential for MVFR in stronger storms.
