.PREV DISCUSSION... /ISSUED 0104 AM CDT Mon Jul 11 2022/

...Synopsis...
Fire weather concerns will predominantly linger across central UT
for today, driven by the potential for dry thunderstorms. A
persistent upper ridge over the southern Rockies will likely shift
slightly southwest in response to a modestly deepening trough across
the Midwest. This will yield a benign surface pressure regime and
low potential for wind-driven fire weather threats (though a few
localized concerns may emerge). However, this will maintain isolated
thunderstorm chances across the greater Four Corners region this
afternoon.

...Utah/Dry-Thunderstorms...
Monsoonal moisture was well sampled by regional 00 UTC soundings
with PWAT values around 0.75 inches in place across AZ and UT.
Nearly 3 km deep dry sub-cloud layers and 100-250 J/kg MUCAPE are
also noted. This thermodynamic environment resulted in a few
thunderstorms Saturday afternoon, and is expected to largely remain
unchanged through this afternoon given the stagnant synoptic regime.
Orographic ascent should support isolated to widely scattered
thunderstorms with the potential for dry lightning strikes. Slow
storm motions (generally < 10 knots) may allow for pockets of
wetting rainfall, but peripheral lightning strikes over receptive
fuels will maintain a fire weather concern.

...Southern Nevada and Western Texas...
Hot temperatures near or above 100 F are expected this afternoon
across southern NV and western TX. These hot temperatures co*bined
with seasonal to below-seasonal dewpoints will result in 10-20% RH
values by late afternoon. While pressure gradient winds will
generally be between 10-15 mph, deep boundary-layer mixing may
support areas of 15-20 mph winds and elevated fire weather
conditions. Confidence in the duration and coverage of these
conditions remains too low for additional highlights.
