.DISCUSSION...
Issued at 304 AM MDT Thu Jun 4 2026

As our weak shortwave trough is moving through this morning, radar
imagery shows a few lingering showers exiting Eastern Idaho early
this morning, though little to no rain has actually fallen. By
midday, expecting to see more sunshine and drier conditions with
highs today in the mid 70s to near 80 degrees for most. Winds will
pick up today with gusts ranging from 30 to 40 mph through the
eastern Magic Valley and Snake River Plain. With these gusty winds,
a LAKE WIND ADVISORY remains in effect for the American Falls
Reservoir from 9 AM to 6 PM today. We are in between systems on
Friday and temperatures will rebound quickly into the 80s to near 90
degrees in the lower Snake River Plain. The wind machine stays on
through Friday and the weekend with the strongest gusts Saturday
into Sunday as our next low moving to our north brings a cold front
through the area. This system looks to bring another chance for
isolated showers and storms to the Central Mountains and Eastern
Highlands on Sunday and a solid cool down to near 70 degrees, but
again brings very little actual liquid precipitation. It looks like
we will have to keep an eye on a more robust system heading our way
next week for any appreciable rainfall and even then we will see how
models change over the next week.

.AVIATION /12Z TAFS THROUGH 12Z FRIDAY/...
Issued at 543 AM MDT Thu Jun 4 2026

A weak shortwave trough moving through the area today is bringing
some SCT to BKN mid level clouds this morning and increasing
winds. Gusts today will reach 25 to nearly 30 kts at BYI, PIH,
and IDA. FEW to SCT mid level clouds will linger a bit longer at
IDA and DIJ later today as clouds begin to clear elsewhere. VFR
conditions persist.

.FIRE WEATHER...
Issued at 304 AM MDT Thu Jun 4 2026

The weak shortwave is making its way through Eastern Idaho this
morning and bringing breezy winds and slightly cooler
temperatures with it. While min RHs heave improved just a bit
with this system, we are still very near RED FLAG conditions
today with much of the eastern Magic Valley and Snake River
Plain around 15 to 20 percent with widespread wind gusts of 25
to 35 mph and a few pockets closer to 40 mph. Any isolated
shower chances early this morning will stay northward and
produce little to no actual rainfall. Drier conditions return by
the afternoon with more sunshine. Min RHs drop again for Friday
afternoon, though wind gusts will be just a bit lighter than
today. Another system very similar to yesterday and today will
pass through this weekend with gusty winds and slight isolated
shower/storm chances on Sunday. It looks to be not until next
week that we see some improvements in min RHs and increasing
potential for a wetting rain.
