.SHORT TERM /THROUGH THURSDAY/...
Issued at 146 AM MDT Wed Jun 4 2025

Early morning satellite imagery is free of any appreciable cloud
cover across most of eastern Idaho. The exception to this is across
the upper Snake Plain and up towards the Island Park area where some
continued cloud cover and very light showers continue this morning
in association with a weak shortwave moving away from the region. As
this feature continues to shift away from us, expect skies to
continue to clear out with a pleasant, seasonal day expected.
Temperatures, once again, will run just a touch below normal levels
with lower valleys right around 70 with mid to upper 60s expected in
the higher terrain. Precipitation today will be hard to come and
this trend looks to continue throughout the remainder of the work
week and as we head into the week. Temperatures begin their upward
trend on Thursday as troughing looks to give way to a major pattern
change towards strong ridging over the region. Most of the region
again looks dry but can`t rule out an isolated shower/storm along
the Montana Divide or towards Yellowstone and the Tetons.

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Issued at 146 AM MDT Wed Jun 4 2025

As we get into Friday, high pressure quickly builds over the area
which should keep things dry through the weekend with temperatures
increasing quickly likely nearing or slightly surpassing 80 on
Friday in the lower valleys, mid to upper 80s on Saturday and upper
80s to lower 90s looking probable for Sunday and Monday with ample
sunshine expected on those days. Models then show the ridge starting
to break down with weak upper level troughing potentially setting up
over the area. Temperatures will drop, slightly, but still remain
above seasonal norms but the more impactful changes will be
increased cloud cover, precip chances and a slight uptick in
synoptic winds over the area. This far out in time though things
can change so stay tuned.

.AVIATION /12Z TAFS THROUGH 12Z THURSDAY/...
Issued at 441 AM MDT Wed Jun 4 2025

VFR conditions to prevail through the period. Winds are expected to
be light and variable for a good portion of the day with mostly
sunny skies expected.

.FIRE WEATHER...
Issued at 146 AM MDT Wed Jun 4 2025

A prolonged period of mostly dry weather is expected for the
upcoming week. Temperatures today will run on the cool side of
normal once again but a warming trend is expected to begin tomorrow
and continue to build in intensity by Friday and into the weekend
with temperatures expected to return into the 80s and 90s for much
of eastern Idaho. Precipitation will be hard to come by through this
period and afternoon RHs will likely drop to around 15-25 percent
each day. Perhaps some precipitation chances return by Tuesday and
Wednesday next week but any QPF looks very light, if any at all
transpires.
