.KEY MESSAGES...

- Rapid Rebound in Temperatures: Increasing warmth on Thursday
  and Friday as cloud cover clears and a high-pressure ridge
  amplifies across the Intermountain West.

- Extended Late-July Heat: A typical summertime heat regime
  takes over Friday into next week. Expect dry conditions for
  most lower elevations, with valley temperatures climbing into
  the mid-to- upper 90s and isolated afternoon storm chances
  restricted to the higher terrain.

.DISCUSSION...
Issued at 348 AM MDT Thu Jul 23 2026

While isolated showers and thunderstorms will still impact the high
terrain today, our weather pattern will trend drier and warmer as a
ridge of high pressure amplifies over the region. Storms today will
be capable of outflow winds up to 45 mph. We should see daytime
highs warm by several additional degrees today due to decreased
cloud cover. Temperatures on Friday will be noticeably warmer as
they increase to well-above normal again in the mid- to upper-90s
across the low elevations and 80s in the mid-elevations and mountain
valleys. Daytime temperature will remain stable through the entirety
of the forecast period. A shortwave on Saturday will bring increased
chances for showers and thunderstorms in an otherwise dry-leaning
pattern. Winds will also increase on Saturday with many areas
expected to observe 30 to 40 mph gusts.

of the forecast period. A shortwave on Saturday will bring increased
chances for showers and thunderstorms in an otherwise dry-leaning
pattern. Winds will also increase on Saturday with many areas
expected to observe 30 to 40 mph gusts. Thus, Saturday is the next
potential chance for elevated fire weather concerns due to both
thunderstorms and increased wind.
