.SHORT TERM /THROUGH TONIGHT/...
Issued at 1255 AM MDT Thu Sep 18 2025
There really isn`t much to talk about in the short term as the
weather will be extremely quiet across eastern Idaho. Mainly clear
skies are in place across the region this morning as seen by
satellite imagery. High pressure remains in control across the
region today which will keep skies mainly clear, with light winds
and no precipitation chances. H5 heights will be on the rise the
next few days as the ridge strengthens and as such, temps will climb
accordingly. Expect widespread 70s today, mainly mid to upper 70s in
the valleys, but it`s not out of the question that a few 80s are
observed especially into the Magic Valley. Overnight lows tonight
into Friday AM will trend above seasonal norms with mid 40s to lower
50s likely in the Snake Plain with 30s and 40s across the high
country.

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Issued at 1247 PM MDT Wed Sep 17 2025
We will monsoon moisture increasing as we head into the weekend.
The initial surge Friday should only produce some
virga/sprinkles across central and eastern Idaho. Coverage for
showers and isolated storms increases over the weekend. The best
chance of showers and storms Saturday will be across the South
Hills, Albion Mountains, and southeast highlands. Sunday stands
a better chance areawide, but more likely over the mountains.
Rainfall amounts don`t look impressive, but we will need to
monitor rainfall potential and amounts to our southwest in the
next few days. Right now, the deeper moisture surge stays to
our south and east. Outflow winds don`t look too impressive
right based on a likely lack of strong instability each day.
The overall wind (outside of storms) should pick up Sunday as
low pressure scoots by to our north. Early next week looks dry
as high pressure quickly rebuilds over the state. After that, we
have low pressure impacting us every 2-3 days...bringing some
wind and chance for moisture and thunderstorms. Even if we cool
down a bit due to clouds and storms over the weekend, overall
temperatures remain at to just above average.

.AVIATION /06Z TAFS THROUGH 12Z FRIDAY/...
Issued at 1255 AM MDT Thu Sep 18 2025
High pressure remains in control of the weather across the area. As
such, winds will be light through the period with mostly clear skies
today. Will likely see some mid/high clouds stream in early Friday
but CIGs will remain well above 3kft keeping VFR in place.

.FIRE WEATHER...
Issued at 1255 AM MDT Thu Sep 18 2025
A ridge of high pressure remains in place for the next couple days,
weakening Friday into the weekend under the influence of low
pressure moving in from the Pacific. Some mid-level atmospheric
moisture arrives as early as Friday, allowing for the development of
weak convection. Very dry low levels will preclude much moisture
from reaching the ground, generally leading to virga or at best a
sprinkle for most areas. Slightly better chances arrive for Saturday
into Sunday as shortwave feature ejects east across the region, but
most of the precipitation chances look to remain isolated at best,
and concentrated across higher elevations. Breezy winds are
anticipated Sunday but humidities should remain above critical
thresholds. Ridge returns for Monday and Tuesday for a return to dry
conditions all districts. Temperatures throughout remain near to
above normal, likely warmest Tuesday. There is a potential for
another system to arrive mid to late week next week, but models are
split on how that system evolves for now, so we will see how things
play out.
