Area Forecast Discussion
National Weather Service Grand Junction CO
322 PM MDT SAT MAY 28 2016

.SHORT TERM...(This evening through Sunday night)
Issued at 322 PM MDT Sat May 28 2016

A modest amount of moisture will continue to be entrained over
the region as the next low pressure system develops over southern
California through Sunday...then gradually shifts east. Today`s
relatively low grade convection will continue into the evening
before diminishing as the diurnal assist diminishes. Look for a
repeat on Sunday temperatures approaching, but still staying shy
of normal for late may. Low temps will also see a little warming,
but will also stay below normal as we should see good clearing
each night.

.LONG TERM...(Monday through Saturday)
Issued at 322 PM MDT Sat May 28 2016

A northern branch shortwave trough will move over the northern
Rockies on Monday, and may result in an uptick in mainly afternoon
convection as it brushes our forecast area. In addition the
southern California low will approach, but will remain to our
southwest. The persistent southwest flow will continue to carry
modest moisture into the region through Tue. Behind these
features, a ridge of high pressure will develop along the west
coast early in the work week, and then move into the Great Basin
by midweek. This high pressure center will continue to strengthen
and will remain to our west through the end of the period. As a
result, temperatures will top out a few degrees above normal late
in the week. Less, but sufficient moisture will remain over the
region for a slight chance of mainly mountain showers and
thunderstorms each afternoon into next weekend.


.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1038 AM MDT Sat May 28 2016

VFR conditions will prevail at airports across eastern Utah and
western Colorado through the next 24 hours. However, daytime
warming and residual moisture will combine to generate scattered
showers and thunderstorms over the higher terrain from 18Z through
03Z this evening. The strongest cells will be capable producing
outflow winds to 35 MPH and will briefly obscure mountains.
Otherwise, winds will be relatively light and terrain driven.


.GJT Watches/Warnings/Advisories...
CO...Flash Flood Watch until 6 PM MDT this evening for COZ007-009.
