.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 /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1142 AM MDT Mon Jun 8 2026

The main concern during this forecast period is the frontal passage
and the potential for strong to severe wind accompanying overnight
convection as it shifts eastward. Have included TEMPOs for
thunderstorm activity and stronger wind gusts during this timeframe,
although some high resolution models feature stronger wind gusts
along portions of the boundary, closer to 50-55 kts. Precipitation
chances will increase along and behind the front with periods of
moderate to heavy rain expected to briefly limit visibility. CIGs
will also trend MVFR heading into the overnight and early morning
hours Tuesday. Winds will begin to increase ahead of the front this
afternoon and evening, with gusts to around 25 kts.

.FIRE WEATHER...
Issued at 1142 AM MDT Mon Jun 8 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.
