DISCUSSION

Issued at 144 AM MDT Tue Jun 30 2026

Tue through Thu night...A trough in the Pacific Northwest will trigger showers and thunderstorms mainly this afternoon and evening. Best precipitation amounts should occur in the central Idaho mountains, and generally better in the north half of the forecast area than in the south half. The trough is slowly moving and will move into western Idaho during the day Wed, and through eastern Idaho Wed night. This will mean a continued risk of light preciptation and thunderstorms. By Thu, the trough has passed. Clearer skies means warming to near normal with diminishing threat of thunderstorms and showers, mainly limited to the eastern half of the of the forecast area.

Fri through Mon...The risk of thunderstorms dies out just in time for Independence Day. Temperatures will be right around normal, which is lower to middle 80s in the Snake River plain/eastern Magic Valley, 70s to around 80 for the mountains and highlands. Temperatures start to soar Sun with some lower elevations surpassing 90 degrees. Showers and thunderstorms don't return until Mon afternoon.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1022 PM MDT Mon Jun 29 2026

There has been some clearing over our southern areas this evening. Clouds and light showers continue for our northern areas with vicinity showers excepted for IDA and DIJ the next couple of hours. VFR conditions are expected to continue. Winds have dropped off for all sites. Clouds will likely be FEW to SCT in the mid-levels for PIH and BYI this evening and BKN for SUN, IDA, and DIJ in the mid-levels this evening into tomorrow morning. However, low-level clouds are possible for IDA and DIJ bringing MVFR conditions tomorrow early morning but are not that likely.

Models show the best chance of showers tomorrow is over the Central mountains. SUN has the best chance of VCSH. Models show very light showers developing well south of all the other TAF sites. So, have taken out VCSH for all TAF sites except KSUN. There is close to a 30 percent chance of afternoon thunderstorms for SUN tomorrow but have held off on a PROB 30 for TSTMS for SUN due to computer model differences the last couple of model runs. Winds will be slightly breezy tomorrow afternoon with gusts of 15 to 20 kts, but mainly for IDA and PIH.

FIRE WEATHER

Issued at 144 AM MDT Tue Jun 30 2026

Afternoon/evening showers and thunderstorms continue through Fri afternoon, although by then it will mainly be in southern and eastern highlands. The holiday should be warm, dry, and quiet wind-wise, with no threat of thunderstorms or any precipitation. The only significant wind will be on Fri afternoon, when temperatures are still near normal for the time of year. Showers and thunderstorms return after the holiday weekend is over, on Mon.
