.DISCUSSION...
Issued at 222 AM MDT Mon Jun 8 2026

Satellite imagery shows weak high pressure over the area with
zonal flow aloft approaching from the west ahead of a Pacific
trough located currently off the Washington and Oregon coasts.

Expect warmer temperatures today, slightly above normal with
overall light winds early before becoming breezy, especially for
our western areas.

The next Pacific shortwave pushes inland on Tuesday. Showers
could arrive as early as Monday night, but much of the region
should see at least some precipitation Tuesday along with a few
thunderstorms. Wetting rains of at least 0.10" are expected for
most higher elevation regions. Precipitation continues mainly
across the north and northeast into early Wednesday. NBM
chances of a two-day total of 0.25" exceed 50 percent for the
Sawtooths, Frank Church, and most of the eastern highlands north
of Soda Springs to the Divide, though most of that total should
fall on Tuesday. Temperatures are expected to cool slightly
under the influence of the cloud cover and precipitation, and
breezy to windy conditions are expected both Tuesday and
Wednesday. Gusts will be around 35 to 50 mph on Tuesday and
around 25 to 40 mph on Wednesday.

Overall dry westerly flow is expected Thursday and Friday and
continue into the weekend, with a warming trend along with
continued breezy conditions.

.AVIATION /00Z TAFS THROUGH 00Z TUESDAY/...
Issued at 938 PM MDT Sun Jun 7 2026

Wind has weakened and will not return to the strength of
yesterday. However, Gusts of 25KT at KPIH and KBYI return Mon
afternoon. Expect gusts of 20KT in downslope conditions at KSUN
Mon afternoon. Otherwise, after some light and variable wind in
the morning, south to northwest wind increases in the morning
and peaks in the afternoon.

An approaching trough does keep the CIG in the mid- to high
altitudes intermittently into the evening. After midnight, KSUN
appears to start getting marginal VFR due to SHRA at KSUN and
KDIJ while the three valley airports have a high likelihood of
some marginal VFR for CIG well after 09/06Z. VSBY should be
little impacted.

.FIRE WEATHER...
Issued at 306 AM MDT Sun Jun 7 2026

Min RHs remain low today (below 15% for Fire Weather zones 425
and 427) with overall lighter gusts early today ahead of a
system approaching that will come through tomorrow. Expect gusts
of near 25 to 30 mph especially for western and northern ridge
tops by late afternoon/early evening.

On Tuesday expect strong winds gusts (35 to 50 mph) with
increased RHs (min RHs of 25 to 60S%) with scattered showers and
isolated to scattered thunderstorms Tuesday with wetting rains
likely for higher elevations. Precipitation chances continue
into Wednesday morning mainly for Fire Weather zone 411.

Temperatures remain below normal through Wednesday with drying
and warming trends along with breezy conditions later in the
week through the weekend.
