.SHORT TERM /THROUGH TUESDAY/...
Issued at 106 AM MDT Mon Jun 9 2025

Today and tomorrow look to be the warmest days for the upcoming week
as high pressure remains in control of the weather across the area.
Temperatures will likely climb into the 90s today across parts of
the Snake Plain and down into the Magic Valley. Low to upper 80s are
expected outside of these areas. Tuesday may be a degree or two
warmer so certainly quite warm for this time of year, about 10-15
degrees above average. Skies will be mostly clear for much of the
day although some CU is expected to develop across the Central
MOuntains. Speaking of which, hi-res CAMs are showing the potential
for some isolated showers/storms to develop in this area later this
afternoon. NBM disagrees and keeps things dry but considering we did
see a few develop on Sunday when models showed next to nothing, it
seems prudent to at least mention some low-end PoPs for this area.
Some gusty winds, lightning and small hail will be possible with the
strongest of storms. Better precip chances seem to be on tap for
Tuesday though as the ridge breaks down allowing for a bit more
moisture to sneak in increasing PoP coverage a bit to the northern
half of the forecast area.

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
Issued at 106 AM MDT Mon Jun 9 2025

Wednesday looks to be the most active weather day across eastern
Idaho as a fast moving shortwave pushes through the region. Vort max
moves through during the peak heating hours of the afternoon and
early evening hours and the enhanced lift should support fairly
widespread shower/storm coverage, especially across the higher
terrain. Lower valleys aren`t exempt from at least some scattered
shower/storm coverage though and some of the storms could certainly
be strong with gusty winds and small hail possible. This feature
pushes well to the east Thursday with weak ridging trying to
establish itself for the rest of the work week and into the weekend.
U/L SW flow looks to become established along with a tightening
pressure gradient as a ridge looks to build well to our southeast.
This could result in a few breezy days at the end of the forecast
period. Temperatures will remain on the warm side of normal
throughout the upcoming week with mid to upper 80s likely in the
lower elevations each day, maybe some 90s as we get closer to next
weekend.

.AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
Issued at 932 PM MDT Sun Jun 8 2025

Overall, expect VFR conditions to continue through tonight and
Monday. Winds should remain fairly light, too. There exists a slight
chance (think 20 to 30 percent) of a few isolated storms off the
terrain Monday afternoon, though currently most look to remain
out of the TAF sites. Timing for these isolated storms would be
from 21Z Monday to 03Z Tuesday, and would be nearest to SUN and
IDA. Kept the PROB30 in for SUN, but it is too low confidence
to add in to IDA or even DIJ at the moment.

.FIRE WEATHER...
Issued at 106 AM MDT Mon Jun 9 2025

High pressure continues to control local weather for a few more days
and temperatures remain well above normal accordingly. Some isolated
shower/storm potential exists across the central mountains today
with a bit more coverage possible on Tuesday as the ridge starts to
break down. A system will move through the area on Wednesday which
should bring our best chance for widespread showers and storms
Wednesday afternoon and evening. Things dry out again towards the
end of the work week and into the weekend with temperatures
remaining above normal each day.

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