DISCUSSION

Issued at 219 AM MDT Wed Jul 8 2026

Expect another round of thunderstorms this afternoon. Best chances are across the southern highlands through the Magic Valley and into the central mountains. Although isolated storms are possible across east Idaho. Dew points are still relatively comparable to what we've seen the past couple days. So expect a mix of wet and dry storms with gusty outflow winds likely. Underneath one of the thunderstorm cores, a quick 0.10 inches of rain or so is possible.

A weak cold front, really more of a dry line, arrives Thursday. Timing is a bit slower than we've seen in previous runs. As a result we could still see some isolated storms Thursday if the dry air doesn't arrive by afternoon. Forecast remains dry for Thursday with uncertainty still high as to whether or not enough moisture is still around for storms.

Hot and dry weather arrives for the weekend. Heat risk values continue to favor potential heat alerts over the weekend as highs approach 100 for many of our lower elevation communities. It looks like it may be a bit breezy over the weekend, so this could feel more like a blast furnace. Temps cool slightly by Monday, but still mid to upper 90s for the lower elevations. By Tuesday temps cool into the lower to mid 90s.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Main concern is impacts from thunderstorms which could affect SUN, PIH, and BYI from mid afternoon into the early evening. These sites have the best chances of seeing storms with at least a 30% probability. Looking at lesser chances at IDA and DIJ. Gusty erratic outflow winds are the main concern with storms this afternoon.

FIRE WEATHER
