Winds will continue to decrease by late afternoon and evening. There is still a very small chance of a shower or sprinkles along the Montana border through early evening, otherwise it will be dry and storm-free until we get to Saturday and Sunday. We will start seeing more wind tomorrow. We are looking at gusts of 25-35 mph especially across higher elevations and portions of the Snake Plain. At the moment, we are not seeing anything that meets thresholds for any wind- related headlines. Winds are stronger over the weekend, with some areas seeing sustained winds approaching 30 mph in some areas of the central mountains and Snake Plain, and gusts of 25-40 mph (locally higher across the central mountains and Arco Desert and INL). By Saturday afternoon, we are expecting some one or more bands of virga/light showers developing during the afternoon, with a couple of thunderstorms possible across the central mountains and along the Montana border. The main impact with that will likely be some enhanced gusty winds. Showers and thunderstorms remain possible Saturday night and Sunday across portions of the central mountains, and most of the eastern and southeast highlands. Highs rebound tomorrow with 80s and even a few lower 90s possible where downslope winds occur. By Sunday, highs drop back into the 70s, and in fact cooler spots may not make it out of the 60s.

The pattern next week is trending cooler and wetter with the closed low slowly tracking across the region. We return back to more 70s Monday and Tuesday, but with the low and increased clouds and precipitation, midweek highs may not get out of the 60s. The colder side of temperature ranges with the low overhead have highs in the 50s for lower elevations. Stay tuned.

Issued at 920 PM MDT Thu Jun 4 2026

High pressure is strong and humidity is extremely dry, to the point that there is no clouds until Fri evening, after 06/00Z at KSUN, after 06/06Z everywhere else. Until then, unlimited CIG and VSBY.

Which leaves nothing but wind shifts/changes for the FM groups. Limited areas tomorrow will increase to G25KT, with most locations only increasing to around 15KT sustained. KSUN does not appear to spend much time from the southeast, with a shift to southwest expected by late afternoon. KBYI appears to have more northerly wind than northwesterly during the afternoon.

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.
