.DISCUSSION...
Issued at 210 PM MDT Sun Jun 7 2026

Satellite imagery shows upper trough axis along western Idaho
border early this afternoon with deep dry slot across East
Idaho. Mid level moisture has largely pushed east into Wyoming,
but a few convective build ups remain. Winds have strengthened
through the Snake Plain, with gusts exceeding 50 mph in a few
locations. Thus will maintain WIND ADVISORY into the evening
across the region. Similarly, combination of gusty winds and
areas of low humidity remain so will also maintain RED FLAG
WARNING. Shortwave axis lifts northeast overnight tonight. Winds
decrease with sunset, and tonight should be cool but above any
concerns for frost or freeze. After a break on Monday with a
rebound in temperatures, the next Pacific shortwave pushes
inland. 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 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
days. Dry westerly flow is expected for the remainder of the
forecast period, with a warming trend and continued breezy
conditions.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1059 AM MDT Sun Jun 7 2026

The big impacts today will be from wind. We are expecting gusts
of 20-35kts to impact all TAF sites except SUN through early
evening. That said, gusts closer to 20kts are possible. It
appears we should see at least occasional, if not a full switch,
to Southwest winds, by mid to late afternoon, then fully
switching to the usual Northwest wind this evening. It is
possible we may see that switch to northwest as early as between
22-00Z. We will see one area of clouds departing with more
arriving this evening and overnight, but still looking at VFR
conditions. There is minimal chance of measurable precipitation,
BUT we wouldn`t be shocked to see some virga or sprinkles.

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

A RED FLAG WARNING continues for Fire Weather Zones 425 and 427
today due to very dry conditions (min RHs of 10-15%) and gusty winds
up to 40 mph. Outside of these two zones, we will see near critical
fire weather conditions with strong wind gusts up to 50 mph in zone
410 and gusts of 25 to 40 mph elsewhere. Min RHs outside of the Red
Flag Warning will range from 15 to 25 percent. Light returns are
visible on radar this morning as a cold front works through eastern
Idaho this morning though little to no actual liquid precipitation
is expected to reach the ground outside of some sprinkles. We should
see a break Monday, followed by an increasing chance of showers
(with wetting rains) and thunderstorms midweek.
