Area Forecast Discussion
National Weather Service Salt Lake City UT
953 PM MDT TUE AUG 23 2016

.SYNOPSIS...Deep moisture will linger across southern and eastern
Utah tonight before much drier air will overspread the area on
Wednesday on northwest flow. Moisture will then make a quick
return Thursday and remain in place through the end of the week.


.DISCUSSION...Weak upper level wave rippling east across southern
Utah and northern Arizona this evening. Behind this feature much
drier air is overspreading the the northern half of Utah on
northwest flow. Lift along the mid level feature combined with
elevated instability and residual moisture will keep the threat
showers and, perhaps, an isolated thunderstorm going across
southern Utah into the overnight hours. Even then southern Utah
should begin drying out from west to east overnight.

With much drier air over the area on Wednesday the coverage of
showers and thunderstorms will be greatly reduced and largely
confined to the higher terrain of southern Utah.

With this update only made minor changes to precipitation
probabilities across central and southern Utah for the remainder
of the night.


.AVIATION...A surface front stalling near the SLC terminal has
delivered a brief spate of northerly winds. These winds are expected
to become light and variable and then predominantly southeast as
drainage winds kick in around 05-06z. There is a 30 percent chance
winds will remain variable as late as 08z. VFR conditions will
persist through the TAF period.
