.KEY MESSAGES, Issued 1015 PM MDT Sat Jun 13 2026...


- Moisture remains in place across southern UT tomorrow afternoon
resulting in more widespread thunderstorms. Strong to potentially
severe wind gusts with isolated flash flooding appears possible with
these storms.

- Hot and dry conditions develop Monday as high pressure builds over
the region. Widespread valley HeatRisk values develop across valley
locations, particularly Tuesday and Wednesday.

- Critical fire weather conditions return to UT Tuesday and
Wednesday as winds pick up out of the northwest.

.DISCUSSION, Issued 1015 PM MDT Sat Jun 13 2026...
 Currently, a midlevel shortwave trough is progressing
southeast across the MT/ID border with another weaker shortwave
stalled over the CA coastline providing persistent SW`erly flow
across southern UT. With time, these two waves will phase together
into tomorrow afternoon. Showers and thunderstorms will persist in
some capacity across southern UT into central UT keeping the airmass
moist and reinforcing a thermal boundary further north. This moist
and unstable airmass will favor thunderstorm development across
central and southern UT tomorrow afternoon as midlevel ascent
increases with the troughs phasing together as they move southeast.
With CAPE on the order of 500-750J/kg amidst steep 0-3km LR`s and
DCAPE in excess of 1200J/kg, strong to severe gusts and potentially
small hail cannot be ruled out with any storm that forms.
Additionally, PWATs ranging from 0.6-0.9" may yield a localized
flash flood threat for any slow-moving or terrain enhanced storms.
High LCL`s on the order of 2500m+ yield some uncertainty with how
much precip will make it to the ground, though storm coverage may
compensate and moisten the PBL potentially resulting in training
storms yielding a heightened flash flooding threat.

Overnight into Monday morning, a dry front will traverse the state
as midlevel ridging begins to nudge into the area. Some residual
moisture may result in some terrain driven thunderstorms across
central and southern UT Monday afternoon, though these will be quite
transient and isolated at best.

Throughout the remainder of the period, an upper jet will progress
south from Canada into the central plains, establishing a persistent
troughing pattern across the central and eastern U.S.. This will
keep much of the west underneath a building ridge, amplifying across
each passing day. Hot and dry conditions are forecast to develop
once again through the long term, potentially persisting into
Saturday and beyond. HeatRisk will see an increase as this occurs,
with the highest confidence of heat related issues developing
Tuesday and Wednesday as HeatRisk enters the moderate range across
most valleys.

Additionally, as ridging builds in and tightens the pressure
gradient Tuesday and Wednesday, midlevel northwesterly winds are
forecast to see an enhancement. Given preceding dry conditions,
these winds will mix to the surface with enhanced dry northwest
winds overspreading much of UT Tuesday through Wednesday. As such,
critical fire weather conditions are expected to return to the state
Tuesday and Wednesday afternoons due to gusty surface winds.

.AVIATION, Issued 1015 PM MDT Sat Jun 13 2026...
KSLC, Issued 1015 PM MDT Sat Jun 13 2026...
The SLC terminal will see VFR conditions
through the night with mostly clear skies. Light northerly winds
will prevail for the remainder of the evening, becoming light and
variable or light southeasterly overnight. Northwest winds are
expected to return with the passage of a cold front between 15Z and
17Z.

.REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions are expected
to prevail through the overnight hours across the airspace with
generally light and terrain driven winds. A few showers and
thunderstorms are expected to continue over portions of southwest
Utah during the overnight and early morning hours, with a low chance
of gusty winds. Scattered showers and thunderstorms are then
expected to develop over southern Utah during the afternoon. Gusty
winds will be possible with any storms that develop along with a low
chance of brief MVFR conditions in heavier showers.

&&

.FIRE WEATHER...Moisture continues to increase across southern Utah. This will
result in higher wetting rain potential with the convection that
develops this afternoon. Lightning and gusty outflow winds will
remain the primary threat. This activity will primarily be along
and south of I-70 with some isolated convection across eastern
Utah. Any storms north of I-70 will pose more of a dry lightning
threat given the higher bases. Conditions will remain dry and warm
across northern Utah.

Conditions become much drier and hotter as the week progresses.
High pressure will be centered to our west which will keep a
northwesterly flow across the area. Relative humidity will drop
into the single digits for most locations by Tuesday with poor
overnight recoveries only getting into the 20-30% range. Breezy
diurnal winds out of the northwest will develop with the highest
gusts to the east of terrain, primarily across eastern Utah. This
will result in critical fire weather conditions for areas where
vegetation has cured.
