.SYNOPSIS...A prolonged stretch of hot and dry conditions
continues into next week. Chances for isolated high-based showers
and thunderstorms in the southern mountains return from Monday
forward.

&&

.DISCUSSION...An area of high pressure will dominate the overall
pattern across the western US into early next week, resulting in a
prolonged duration of above-normal heat. Near-average temperatures
today tempers HeatRisk across a majority of the region except
southern Utah, where areas of Moderate HeatRisk have emerged.
Moderate HeatRisk becomes widespread across Utah and southwest
Wyoming by Saturday, continuing through early next week. Some
localized areas of Major HeatRisk emerge Sunday and Monday across
warmest valleys of southern Utah, including St. George and portions
of Lake Powell. If you plan to spend time outside this weekend, make
sure to stay hydrated and take breaks in the shade or air
conditioning often.

The ridge axis shifts offshore on Monday, which will allow modest
moisture transport into the region. PWAT values gradually climb to
around 0.6-0.7" on Monday, with strong surface heating sparking
afternoon convection. As such, daily afternoon thunderstorm chances
return Monday, continuing trough the remainder of the week. Coverage
will be quite isolated and mainly tied to higher terrain as little
synoptic forcing will be in place. A shortwave trough deepening
along the west coast will introduce better dynamics over the region,
which may lead to more widespread shower and thunderstorm chances in
addition to increased afternoon winds through the end of the work
week.

.AVIATION...KSLC...VFR conditions will persist for the KSLC terminal
through the period. Dry weather with clear skies will continue with
typical diurnal wind switches from north this afternoon to south
tonight and back to north on Saturday.

.REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions will persist
for the entire airspace through the period. Dry weather and clear
skies will continue. Winds will become largely light and terrain
driven as high pressure builds into the area.


&&

.FIRE WEATHER...Temperatures remain near climatological normals
today, but are expected to nudge several degrees above average
this weekend and into early next week as high pressure strengthens
across Utah. This heat will be complimented by very dry
conditions, with daytime relative humidity values in the single
digits to low teens across the state, in addition to poor
overnight humidity recoveries. Worst overnight recoveries are
expected through Tuesday morning, with the main areas of concern
across southwestern Utah and the West Desert, with recoveries
between 25-35%, and eastern Utah, with recoveries between 20-25%.

The area of high pressure moves slightly west Sunday into Monday,
which will allow modest mid-level moisture to sneak into the
southern half of Utah. As such, chances for afternoon high-based
showers and isolated thunderstorms increase on Monday afternoon,
remaining a daily feature through the remainder of the week. A
weather system dropping down the west coast on Wednesday brings
increasing instability and thus increasing coverage of afternoon
showers and thunderstorms through the latter half of the week. We
will also see slight improvement in overnight humidity recoveries
from Wednesday morning through the remainder of the week as a
result, but overall, not enough to sideline fire weather concerns.
Chances for wetting rains from showers and thunderstorms next
week remains low, so the main concern will be lightning and gusty
and erratic outflow winds, especially after a long stretch of hot
and dry conditions.
