Area Forecast Discussion
National Weather Service Salt Lake City UT
1006 PM MDT Mon Apr 20 2026

.KEY MESSAGES...

- Anomalous heat with near record high temperatures is once again
  expected Tuesday.

- Gusty south to southwest winds will develop Tuesday, with around
  a 60-80% chance of gusts 40-50 mph particularly across many
  western valleys. Gusty conditions will redevelop across eastern
  valleys Wednesday.

- An unsettled and cooler pattern returns by Wednesday as a trough
  moves in, bringing periods of valley rain and mountain snow.
  Following systems look to maintain this pattern into the
  weekend.

- Locally freezing morning temperatures return to some rural
  valley locations Thursday through Saturday.

&&

.DISCUSSION...Overall synoptic pattern remains fairly unchanged
since yesterday evening. Ridging extends through the Rockies
while a large scale trough continues to slowly move towards the
Pacific coast. Overhead there has been a weak upper level weakness
shifting through, which in combination with modest southerly
moisture advection has resulted in some isolated terrain initiated
showers, but little of substance. Otherwise, the strengthening
deep southwesterly flow has just resulted in somewhat breezier
conditions through the day along with very mild temperatures.

The aforementioned trough will begin to push inland Tuesday, with
southwesterly flow over the Great Basin becoming further
enhanced. This will once again result in a very mild day, but also
continue to strengthen winds and gusts. While widespread wind
gusts in the 20-40 mph range are expected throughout the region
through the afternoon, the strongest signal for strong winds is
noted across western Utah valleys, and especially the West Desert.
These locations have around a 60-80% chance to see gusts more in
the 40-50 mph range, and as such a Wind Advisory is in effect from
Tuesday afternoon through Tuesday evening. A cold front will
start pushing into Utah overnight into Wednesday morning, and
winds and gusts across western valleys will relax some in turn
behind the front. Eastern valleys ahead of the front however will
see another period of gusty winds, with around a 40-60% chance of
areas of gusts in the 40-50 mph range.

As the cold front and parent trough advance into the area
overnight through Wednesday, precipitation chances will start to
increase. With lingering moisture and continued forcing with
subtle impulses within the broad trough, periods of showers then
continue through Thursday. In general, the orientation of the
moisture advection will favor heightened precipitation chances and
water amounts north of around I-70/US-50, and particularly for
the northern Utah mountains. Forecast water amounts have not
changed markedly from prior forecasts, with 25th-75th percentiles
for northern valleys still around 0.25 to 0.75 inches, and more
around 0.5 to 1.2 inches for northern mountains. With snow levels
only falling into the 6000 to 6500 feet range or so, with northern
mountain snow accumulation amounts broadly around 3" to 6". With
west to northwest flow returning behind the front, will likely see
some local orographically enhanced amounts at favored northern
terrain closer to 10".

Less certainty is noted in the pattern evolution into the
weekend, though models do continue to favor it remaining
unsettled. Friday will see a shortwave within a broader closed
upper level low sink in, and potentially phase with some southern
stream energy through the weekend. Given the complex evolution,
models seem to have differences in timing and the degree of
phasing, which will in turn influence timing , location, and
amount of precipitation. In any case, the pattern should favor at
least some flavor of continued unsettled and cool weather.

After the initial cold frontal passage Wednesday, colder air
returning with the trough will result in potential for localized
overnight freezing temperatures in some rural valleys. The biggest
question for Thursday and Friday morning looks to be to what
degree cloud cover can clear, as lingering clouds will help keep
temperatures from falling as rapidly. As such, looking at around a
10-30% chance for locally freezing temperatures those mornings. A
brief intrusion of some drier air Friday night into Saturday
morning looks to have the best shot of resulting in better
clearing, and freeze probabilities increase accordingly more in
the 40-60% chance range.

&&

.AVIATION...KSLC...VFR conditions will continue through Tuesday with
periods of scattered mid and high clouds. South winds will prevail
through the night, increasing in speed and becoming gusty by mid to
late morning on Tuesday.

.REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions will continue
with periods of scattered mid and high clouds. Overnight, expect
typical drainage winds at most terminals, then south to southwest
winds will increase and become gusty by late morning or early
afternoon on Tuesday.

&&

     for UTZ101-115-122-123.
