.KEY MESSAGES..

- Isolated showers and a few thunderstorms tomorrow as a shortwave
  moves through.

- Dry and warm conditions for the latter half of the week before a
  substantial trough moves through, potentially interacting with
  tropical moisture, and producing widespread precipitation.

.DISCUSSION, Issued 1048 PM MDT Mon Oct 5 2026...
A weak shortwave is currently moving through the
area. This is evident by some convection currently moving into
northwestern Utah. This activity will remain weak and isolated
through the overnight hours and into tomorrow. This will also
bring temperatures down about 5 degrees compared to where they
were today. This shortwave will continue to shift east with some
isolated convection still possible across the Uinta basin and
surrounding terrain on Wednesday afternoon. Dry and stable
conditions settle back into the area through the remainder of the
week and into the first part of the weekend.

Guidance continues to trend towards the wetter solution with ~75%
of ensemble members supporting a trough sliding out of British
Columbia and into the PNW before phasing with tropical moisture
from the remnants of Hurricane Tropical in the eastern Pacific and
bringing widespread precipitation to most of the CWA. Ahead of
this trough, southerly winds will start to increase on Saturday
and remain elevated through Sunday before a cold front moves
through and transitions the winds to a north and westerly
component. There is still ~25% of the members that keep the track
of the trough more continental in nature where it doesn`t pull in
the tropical moisture.

Of the 75% of the wetter members, a majority of them keep a
prolonged period of widespread precipitation starting Saturday
night and lasting through early Wednesday as the trough becomes
cutoff from the northern stream and spins across Utah. Snow levels
will start between 11,500-12,000 feet elevation before gradually
dropping down a couple thousand feet lower in elevation. Mean
700mb temps are ~1C with the coldest solutions down to -9C by
Tuesday which could be cold enough to support some snow down to
valley floors, but this solution is very much the outlier.
High elevation mountain snow could be substantial given widespread
QPF amounts 1-2" with some models showing 3"+ across the higher
terrain of the Uintas.

.AVIATION...
KSLC...VFR conditions will prevail at the KSLC terminal through the
TAF period with persistent mid-to-high level cloud coverage. Winds
remain generally light out of the southeast this morning before
transitioning northwesterly around 18z. A period of gusty easterly
winds may develop between 00-03z due to outflow winds from
convective activity across the Wasatch.

REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions are expected to
prevail across all regional terminals through the TAF period with
persistent mid to high level cloud coverage, especially across the
northern portion of the airspace. Winds remain generally light and
diurnally driven, outside of gusty and erratic outflow winds 30-35
kts associated with showers and thunderstorms developing along the
higher terrain this afternoon.

&&

.FIRE WEATHER, Issued 405 AM MDT Tue Oct 6 2026...
A weak storm system traversing the region will
result in enough instability this for isolated showers and
thunderstorms to develop. Coverage will favor northwest Utah this
morning, before developing across the higher terrain across much
of the state this afternoon. Storms will be mostly dry, with
potential to produce dry microbursts with gusts between 40-50 mph.
High pressure redevelops across the western US through Friday,
keeping conditions dry and mild areawide before a potent weather
system digging into the Great Basin this weekend brings much
cooler and wetter weather into early next week. Potential for
widespread wetting rains associated with this system has increased
with recent guidance.
