Area Forecast Discussion
National Weather Service Salt Lake City UT
958 PM MDT MON AUG 22 2016

.SYNOPSIS...Moisture will remain in place across all but the
northwest third of Utah tonight and Tuesday, as an upper level
disturbance drifts slowly across the southern reaches of the
region. A northwest flow will usher in drier air across the
forecast area on Wednesday.

&&

.DISCUSSION...Deep moisture remains in place across the southern
half of Utah this evening with precipitable water values of .75"
to 1". Numerous showers and thunderstorms across southern Utah
this afternoon, but coverage has been diminishing rather quickly
this evening. CIN has quickly developed for surface-based parcelsthis
evening, but weak elevated instability will remain in place in
place through the night.

There is a considerable amount of convective activity in southeast
Nevada associated with a mid level circulation. This circulation
will drift east across northern Arizona tonight. This feature
combined with an area of persistent mid level convergence across
southern Utah and lingering elevated instability should keep
isolated to scattered showers and a few thunderstorms across
southern Utah through the night.

Northern Utah and southwest Wyoming will remain partly to mostly
cloudy through much of the night as cloud debris stream across
the area from convection to the south and west. Low temperatures
will remain about five degrees above normal in most areas.

With this update only made minor changes to precipitation
coverage across southern Utah and to increase cloud cover across
northern Utah tonight.


&&

.AVIATION...Northwest winds at KSLC will persist through 0500-0600
UTC before southeast drainage winds are expected to return.
However, there is a 30 percent chance that the northwest winds
will persist past 0600 UTC. Otherwise, VFR conditions will prevail
through the TAF period.

&&

.SLC Watches/Warnings/Advisories...
UT...Red Flag Warning from noon to 9 PM MDT Tuesday for UTZ479.
WY...Red Flag Warning from noon to 9 PM MDT Tuesday for WYZ277.
