.KEY MESSAGES...

- Near record to potentially record breaking heat will develop
  this weekend into early next week, persisting through mid-week.

- Widespread anomalous heat, single-digit daytime RH, and poor
  overnight humidity recoveries bring elevated fire weather
  conditions Sunday onward.

- There is a very low chance of any precipitation through at least
  midweek next week.

.DISCUSSION...Northwest flow remains across Utah this afternoon.
High pressure will continue to shift into the Desert Southwest,
with a ~590dam high centered over southern California/Arizona by
Sunday. Expect temperatures to trend warmer Sunday, reaching to
near record levels by Monday.

Upper level ridging will gradually shift east mid-week as a trough
approaches the Pacific Coast. This may allow for mid-level
moisture advection and an attendant threat of high-based showers
and thunderstorms as early as Wednesday. Current guidance suggests
this high-based convection will be dry, with little threat of
precipitation reaching the surface. The vast majority of ensemble
members keep nearly the entire CWA dry through at least Wednesday,
if not longer.

&&

.AVIATION...KSLC...Operational weather concerns will remain
minimal through the valid TAF period under largely clear skies and
stable conditions. Northwesterly winds currently in place are
expected to return to southeast around 03z per norm.

.REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions will persist
for the entire airspace through the period. Dry conditions and
clear skies will continue with light and diurnally driven winds.

&&

.FIRE WEATHER...High pressure will continue to build into the region
through Saturday, bringing near record temperatures and very dry
conditions. By Sunday, many areas will see low teens to single
digit humidities with poor to very poor overnight recoveries.

There is little relief in this pattern through at least
Thursday. Locally critical fire weather conditions will develop
in areas if any fuels transition to critical during this time
period.

A portion of the guidance suggests a low threat of high-based
thunderstorms Wednesday and Thursday afternoon and evening. Given
very dry antecedent conditions, this will be worth monitoring
going forward.

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...None.
WY...None.
