.DISCUSSION...
Issued at 944 PM MDT Fri May 8 2026

HOT, BREEZY, AND MOSTLY DRY INTO NEXT WEEK:

This weekend, dry, northwesterly flow will begin to dominate,
keeping conditions quiet across the vast majority of the region.
Saturday will be a rinse and repeat of Friday with highs 10-15
degrees above normal, and gusty winds into the afternoon hours.
Some fire weather concerns do exist Saturday, refer to the fire
weather section for more information on that. Isolated
showers/storms cannot be ruled out over the southern mountains
on Saturday afternoon (10-20% chance), but measurable
precipitation looks hard to come by.

As we move away from Saturday, an amplified upper-level ridge
begins to dominate the western CONUS, which will persist most,
if not all of next week. The most notable part of this pattern
will be hot and dry conditions. Throughout the week, highs will
be 10+ degrees above normal region wide, with Monday through
Wednesday potentially exceeding 20 degrees above normal in some
places. We could see a new daily record highs set during this
stretch.

.FIRE WEATHER...
Issued at 944 PM MDT Fri May 8 2026

Tomorrow afternoon, wind gusts up to 35 mph and relative
humidity values as low as 11-16% will combine to create critical
fire weather conditions in far northwest Colorado, where fuels
are also deemed critical. As a result, a Red Flag Warning from
2-8 PM.

Hot, dry, and windy conditions will prevail into next week,
with temperatures surging well above average.
