Area Forecast Discussion
National Weather Service Salt Lake City UT
1008 AM MDT Tue Jul 24 2018

.SYNOPSIS...A ridge of high pressure will slowly move westward
across Arizona through Friday. This will effectively shut off the
monsoonal flow from midweek through this weekend bringing hot and
drier conditions to the region.

&&

.DISCUSSION...High pressure remains the dominant feature over the
Desert Southwest this morning, with the upper level circulation
center expected to slowly shift from New Mexico to Arizona through
today. This will lead to a hot series of days for Utah and
southwest Wyoming, especially in far southern Utah, where an
Excessive Heat Warning is in place today through Thursday. The
northern two- thirds of the forecast area will have above normal
temperatures, but likely not record breaking.

Enough moisture is still lingering under the ridge to allow for
another afternoon of showers and thunderstorms forming over Utah's
mountains. Isolated severe thunderstorms or flash flooding remains
possible, but in general coverage should be relatively limited.
One area where coverage could be a bit enhanced is eastern Nevada,
with a weak disturbance passing over the area on the west side of
the high circulation; there is the potential that a few of these
storms could move into western Utah late this afternoon or this
evening.

A minor update to the forecast was sent earlier this morning to
add mentionable POPs to southeast Utah, as well as adding the
previously discussed threat of storms in far western Utah for this
afternoon. Otherwise, the forecast looks good, and no further
updates are planned.

&&

.AVIATION...Operational weather concerns will remain minimal at the
KSLC terminal through today, as VFR conditions will prevail. A
southeast drainage wind should give way to a northwest lake breeze
toward 18Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...Excessive Heat Warning until 10 PM MDT Thursday for UTZ019-021.

WY...None.

PUBLIC...Schoening
