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.
