DISCUSSION

Issued at 220 AM MDT Sun Mar 22 2026

Satellite this morning shows the cold front exiting eastern Idaho as clouds move southeast into Utah and Wyoming. We'll finally take a little break from setting record highs today as cooler air arrives, meaning highs will be near 60 instead of near 80. Our pattern keeps us in zonal flow aloft as an area of low pressure hangs out in southern California for today and tomorrow before weak high pressure builds back in over the area on Tuesday. Today's "cool down" is a one-day-only deal though, and we'll be back in the mid to upper 60s and near 70 again by Monday afternoon. More of us will be back into the low and mid 70s for Tuesday and Wednesday with wind gusts also increasing. For Tuesday and Wednesday afternoons, gusts will reach 25-35 mph with the upper Snake River Plain approaching 40 mph on Wednesday. Winds will be a bit stronger late Wednesday as another cold front moves through the area. Currently, models are showing some precipitation chances in the Central Mountains and Eastern Highlands with the front, but they were also doing the same thing a few days ago ahead of yesterday's cold front, so we'll have to see how that trends over the next several days. Even though it does show PoPs, there is very little QPF in the forecast with it, less than a quarter of an inch in the Central Mountains and almost zero for the Eastern Highlands. It will at least drop our temperatures back down into the 50s for Thursday.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/

Issued at 948 PM MDT Sat Mar 21 2026

High pressure will return in the wake of the Saturday cold front. There is one residual upper level trough expected to develop CIGs around 5000ft-7000ft AGL in some of the TAFs, mostly in the south. But this should move out before airdromes reopen to normal operations in the morning. SKC to SCT sky conditions are expected during the day, then shortly after the end time of 23/06Z more clouds will be moving in, as can be seen in the 30 hour TAF for KSUN.

Wind has been elevated to strong the past few days, but this is (finally!) ending with weaker wind aloft in the afternoon. However, it is still from the usual directions and should not be a factor.
