Area Forecast Discussion
National Weather Service Salt Lake City UT
1007 PM MDT Wed Apr 15 2026

.KEY MESSAGES...

- A strong cold front will bring much colder temperatures to the
  entire region with hard freeze conditions likely across most
  areas above 3000 feet elevation.

- Accumulating snow has trended down across most valley locations
  given that precipitation will be short-lived, but a quick burst
  of snow will accompany the cold frontal passage.

- Strong northerly winds will occur across lower Washington County
  in areas that gust strong in northerly flow, such as the Black
  Ridge Canyon.

&&

.DISCUSSION...Latest trends in the model data indicate a more
progressive cold front with a shorter lived precipitation band
associated with it. Guidance has trended down the QPF totals
dramatically over the last 24 hours. QPF totals across the
northern mountains, where the highest totals will be, are between
0.3 and 0.65 inches (25th-75th percentile). With a 10:1 ratio we
get roughly 3 to 6 inches across the highest terrain. Valleys are
looking more like 0.05 to 0.20 which would not translate to much
in the way of snow, even with a quick transition to snow, given
the warm surface temperatures. Soil temperatures are currently in
the 50s with 60s across paved surfaces.

All of that being said, the dynamics are still pretty impressive
with this cold front so a quick burst of snow along and behind the
front is still expected which could briefly drop visibilities and
under the heaviest bands could lead to a slush up on roads.
Timing of the front has it moving through the Wasatch front
between 12pm-3pm and through Cedar City 8pm-10pm.

Northerly gap winds will develop behind the front across lower
Washington county. So areas such as Black Ridge Canyon and west
of St. George will see gusty northerly winds picking up just
before midnight and persisting through the morning hours. Winds
aloft at 700mb are only ~15-25 mph so this will limit the surface
winds, but a few isolated areas could approach 58 mph gusts.

The area of greatest confidence will be the very cold airmass (for
this time of year) that will filter into the entire area by Friday
morning. Most locations above 3000 feet elevation will see
freezing temperatures. In fact, most locations will see a hard
freeze with temperatures dipping into the 20s and some areas into
the teens. This will be enough to damage early season plants and
cause damage to exposed pipes that have already been de-
winterized. Consider protecting any exposed plants or pipes.
Saturday morning will also be very cold with more widespread
freezing temperatures.

Temperatures will quickly rebound through the weekend with
temperatures approaching the upper 70s by Monday as a ridge builds
into the Great Basin. This ridge will keep conditions dry and
stable through early next week. Another cutoff low will be moving
into the west by midweek, but details with these cutoff lows
remain fuzzy given the uncertain track and timing of these types
of systems.

&&

.AVIATION...KSLC...South to southwest winds will likely prevail
through the night, although nearby passing rain showers will be
capable of bringing periods of variable winds. Winds are then
expected to shift to northerly behind a cold front which is expected
to arrive between 14-15z. While rain showers may fill in shortly
behind the cold front, the best window for any precipitation will be
between 18-21z when it will be cold enough for precipitation to
transition from rain to snow. As such, expect a brief period of IFR
to low-end MVFR (with a 15% chance of LIFR) conditions with snow
during that window. Otherwise, CIGS below 7kft AGL will be likely
late morning through midafternoon. By late afternoon into the
evening, expect a gradual clearing trend as precipitation ends.

.REST OF UTAH AND SOUTHWEST WYOMING...Southwest winds will prevail
across Utah and southwest Wyoming before turning more northerly
behind a cold front. This cold front is expected to arrive at KLGU
around 11z, KSLC around 15-16z, KPVU around 17-18z, and KCDC around
01-02z. Ahead of the front, occasional rain showers can be expected
across northern Utah overnight. Behind the front, precipitation is
expected to fill in for a few hours. Snow levels will eventually
fall as low as 4kft MSL, allowing precipitation to transition from
rain to snow at most terminals. As such, expect a brief period of
IFR to low-end MVFR (with a 15-20% chance of LIFR) conditions with
snow during that window. Otherwise, low CIGS will result in mountain
obscurations near the frontal precipitation band.
