.SHORT TERM /THROUGH TONIGHT/...
Issued at 145 PM MDT Sat Aug 30 2025

Upper ridge beginning to amplify through the Great Basin per WV
satellite imagery. A few afternoon build-ups developing over higher
elevations in East Idaho, but skies remain generally sunny most
areas. Still a potential threat for a few showers to develop across
the central mountains and across the south hills, but do not
anticipate significant development either in intensity or coverage.
Only other issue of concern will be smoke inundation from wildfires
across the Northwest. Carried Patchy Smoke across the region per
HRRR smoke fields through at least tomorrow.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 145 PM MDT Sat Aug 30 2025

Most of the week remains under the influence of amplified ridge of
high pressure across the west. Dry conditions largely forecast, with
temperatures remaining generally in the 80s. There is still a non-
zero chance of a thunderstorm or two breaking out over higher
terrain dayto-day, but confidence is low and the model means and
forecast remain dry through Friday. By Friday, ensemble clusters
begin to break down the ridge and allow moisture around the high
into East Idaho.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 538 PM MDT Sat Aug 30 2025

Nearly ideal conditions for aviation interests across eastern
Idaho. VFR expected to prevail through the period with mostly clear
skies and very light winds. A few light showers are in the central
Idaho mountains and should dissapate by 8pm. light showers and/or
virga possible near KSUN until 8pm.  Expect this quiet weather to
continue throughout the holiday weekend.

&&

.FIRE WEATHER...
Issued at 145 PM MDT Sat Aug 30 2025

Mostly clear skies in place this afternoon with the warmer, drier
pattern beginning to take hold over the region. Will likely still
see some very isolated showers/storms develop this afternoon across
some of the higher terrain but these will be even more isolated than
yesterday. Temperatures will continue to warm through the holiday
weekend, back closer to normal, and likely topping out just a bit
above normal by the early to mid part of the upcoming week. RHs will
get close, but stay above, critical levels through the period with
winds remaining light.

.PIH WATCHES/WARNINGS/ADVISORIES...
None.
