Area Forecast Discussion
National Weather Service Salt Lake City UT
1031 PM MDT Tue May 12 2026

.KEY MESSAGES...

- Record to near record heat continues Wednesday.

- Critical fire weather conditions are expected Wednesday
  afternoon and evening due to gusty winds and very low relative
  humidity. Red Flag Warnings have been issued accordingly.

- A categorical Marginal Risk (level 1 of 5) of severe weather is
  noted or portions of northern Utah and southwest Wyoming
  Wednesday afternoon and evening. This is for thunderstorms, some
  of which will be capable of strong to severe wind gusts in
  excess of 58 mph.

- Strong winds and gusts will accompany the passage of a dry cold
  front in wind prone areas near terrain in northwest Utah late
  Wednesday evening into the overnight hours. This would include
  areas such as Wendover, Park Valley and Curlew Junction. A High
  Wind Watch has been issued accordingly.

- Locally critical fire weather conditions may return to southwest
  Utah Saturday as an approaching cold front results in gusty
  winds.

.DISCUSSION...Another day dominated by a strong ridge of high
pressure Tuesday. While this ridge is continuing to slowly
progress eastward, it has resulted in afternoon highs around 15-25
degrees above normal, tying or breaking records in some
locations. While more cloud cover formed off of the terrain, and
even a few light echoes were noted over the high Uintas, largely
the area has remained very dry.

Wednesday looks to have potential to be an active day in terms of
weather, and multifaceted in potential weather related hazards.
This will be due to the ridge continuing to shift east while a
trough and associated cold front push deeper into the Great Basin.

Deep southwesterly flow between the two features will increase,
but 700 mb temperatures around 10C to 12C will result in another
day with anomalously warm temperatures. While forecast highs are a
few degrees or so cooler than that of Tuesday, in general still
expect temperatures to run 10F to 20F above normal. With
reasonable cooling overnight, HeatRisk will drop somewhat, but
remain in the "Minor" category (risk level 1 of 4). This would
pose the greatest threat to those sensitive to heat, especially
without proper cooling or hydration. Those planning any strenuous
outdoor activities should have a means to stay well hydrated and
cool down as needed.

The aforementioned deep southwesterly flow will also result in a
corresponding increase to winds and gusts across the area through
the day Wednesday. Widespread gusts of 25-40 mph are expected,
with around a 20-40% chance to see gusts exceed 45 mph in portions
of southwest and west Utah. These strong winds will have
potential to result in patchy areas of blowing dust, which could
result in locally reduced visibility. Additionally, the south to
southwesterly directional component could yield some moderately
hazardous travel conditions to higher profile vehicles on routes
where this would be a crosswind, such as I-80, US-50, and SR-21.
The combination of strong winds and dry conditions will also
result in areas of critical fire weather conditions in portions of
southwestern Utah Wednesday afternoon and evening (see Fire
Weather discussion).

The synoptic flow pattern will also become more favorable for
modest moisture advection into the area Wednesday. In combination
with widespread destabilization on the order of around 200-400
J/kg MUCAPE, anticipate convective development through the
afternoon and evening hours. Coverage is anticipated to be highest
in northern Utah and southwest Wyoming, and down through central
Utah along/east of the high terrain north of the I-70 corridor or
so. This moisture will be more concentrated in the mid levels, and
given a well mixed deep boundary layer due to the strong heating,
convection will be high-based in nature. The resulting vertical
profile is that of an "interted-V", which would support potential
for strong wind gusts in what storms do form, especially those
that become better organized. To that end, effective shear on the
order of 20-40 kts should support some of these storms becoming
more organized, and even offering potential for some isolated
small hail in addition to strong wind gusts (the primary threat).
With that, the SPC has highlighted portions of northern Utah and
southwest Wyoming in a categorical Marginal Risk (level 1 of 4)
for severe weather Wednesday, particularly for severe wind gust
potential (58 mph or greater). While the probability is lower, a
couple storms may even be capable of significant wind gusts at or
above 75 mph. Showers and thunderstorms will diminish in coverage
and shift out of the region through the evening hours.

While the storms wane, a dry cold frontal boundary associated
with the trough will begin to advance from northwest to southeast
into Utah Wednesday evening. While the airmass associated with it
is not really anomalously cold, the push into the departing record
warm airmass results in a strong thermal gradient, and a
correspondingly strong pressure gradient along the front. In turn,
as the front passes it will cause an abrupt shift to gusty
northwest winds. While at most lower elevations the period of
gusts associated with frontal passage aren't anticipated to be too
impactful (~20-35 mph), prone areas of northwest Utah especially
downwind of terrain will see wind gust potential amplify. These
places, such as Curlew Junction, Park Valley, and Wendover will
see around a 40-70% chance of a period of gusts in excess of 58
mph for a few hours following frontal passage. In regards to
timing, the current consensus has the front advancing into
northwest Utah around 6 PM, reaching the I-80 corridor and
portions of the Wasatch Front by around 9 PM, and continuing
southeastward thereafter.

Thursday will see more quiescent conditions across much of the
area. Cooler air associated with the trough will sink at least as
far as the I-70 corridor or so. Forecast afternoon highs in turn
decrease around 5-10 degrees in central Utah, and 10-20 degrees or
so in northern Utah and southwest Wyoming. Modestly gusty post
frontal winds around 25-40 mph or so will continue Thursday
afternoon across some areas such as the western Uinta Basin and
Castle Country.

Near to slightly above normal conditions continue into Saturday,
with dry conditions maintained across most of the area. Breezy
conditions appear set to return Saturday as another trough and
associated frontal boundary progress through the Great Basin.
Ensemble consensus continues to support this trough in some
fashion, with a frontal passage late Saturday into Sunday. There
is still a bit of uncertainty in details though. Approximately 60%
of ensemble members carry a shallower and drier trough, with the
other 40% deeper, colder, and more moisture rich. In either case,
as of now it appears favored that we'll see a pretty substantial
shot of cold air with this one. Forecast temperatures Sunday fall
substantially, with afternoon highs forecast around 5-10 degrees
below normal across central to northern Utah and southwest
Wyoming, and near normal across southern Utah. Temperatures would
then start to gradually moderate back upwards into the early
portion of next week.

.AVIATION...KSLC...VFR conditions prevail at KSLC through early
Wednesday afternoon, with mostly clear skies overnight giving way
to increasing mid-to-high level cloud coverage around mid-
morning. Diurnally driven winds continue overnight before an
approaching weather system brings increased southerly winds after
~12z, gradually increasing through the early afternoon. Scattered
high- based thunderstorms are expected to develop along the high
terrain after 19z, with chances to impact the terminal with gusty
and erratic outflow winds in excess of 45 kts and potentially
small hail between ~21-24z. There is a 20% chance for wind gusts
to exceed 55 kts within 25 km of KSLC.

.REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions persist for all
regional terminals through the period. Clear skies overnight give
way to increasing mid-to-high level cloud cover early Wednesday
morning. Diurnally driven winds overnight increase out of the
south- southwest for all regional terminals Wednesday morning,
gradually increasing through the afternoon with widespread gusts
to 30-35 kts across southern Utah. Isolated to scattered
thunderstorms are expected to develop along the high terrain of
central and northern Utah during the early afternoon, with
coverage expanding northeastward through the late afternoon. These
high-based thunderstorms will be capable of producing gusts in
excess of 55 kts as well as small hail.

&&

.FIRE WEATHER...The hot and dry conditions persist into Wednesday.
After minimal overnight recoveries, daytime relative humidity
minimums once again fall into the low teens to single digits.
Widespread gusty winds on the order of 25-40 mph will develop
across Utah ahead of an approaching system as well. In
southwestern Utah, this will result in the development of critical
fire weather conditions in fire zones 495, 496, and 497 through
the afternoon and evening.

Enough mid level moisture pushes in Wednesday to result in
isolated to scattered high-based thunderstorm development
Wednesday afternoon and evening, with coverage primarily along and
north of the I-70 corridor. More isolated activity may develop
further south as well, especially along the terrain. Given the
high-bases and limited moisture, most of these thunderstorms will
be dry in nature, offering little chance of wetting rains.
Lightning and gusty outflow winds 40-60 mph will be likely with
much of this activity, and a few gusts up to 75 mph will be
possible in any stronger and more organized storm.

A cold front will progress through Utah from northwest to
southeast late Wednesday evening on through the night. This front
will be dry in nature, and result in an abrupt wind shift to the
northwest as it passes, with a period of gusty winds also
immediately following the frontal passage. Temperatures will drop
10-20 degrees across northern Utah, around 5-10 degrees through
central Utah, and up to a few degrees through southern Utah.
Overnight moisture recovery following the front will improve
slightly for the next following few days, but widespread daytime
values in the teens to single digits will remain. Models suggest
another cold front may push through late Saturday into Sunday,
bringing gusty winds Saturday, and renewed potential for elevated
to locally critical fire weather conditions where fuels are
sufficiently cured.
