.DISCUSSION...
Issued at 147 PM CDT Sat Jul 26 2025

Thunderstorms are just beginning to develop over CO, WY, and the
Neb panhandle. This scattered activity will approach the area
late this evening (9pm-12am), but is expected to be on a
weakening trend as it does so. If these storms can persist long
enough, areas west of Highway 283 could see a brief thunderstorm
and perhaps some gusty winds as they dissipate.

For Sunday and Monday, the main story is the heat as upper level
ridging builds over the central CONUS. Widespread temperatures
in the 90s and low 100s will combine with dewpoints in the
60s/70s to result in widespread heat index values in the 100-110
range...and possibly as high as 115 in eastern areas that
maintain higher dewpoints on Monday. As such, a Heat Advisory
and Extreme Heat Warning are now in effect for Sunday and
Monday.

The ridge begins to break down on Tuesday, although high
temperatures are still expected to reach the 90s for most of the
area. Heat index values could even approach advisory criteria
(105) in some localized areas.

Tuesday night, the arrival of a shortwave brings a good chance
(40-70%) for thunderstorms to the area, and this fairly active
pattern will persist through much of next week. Overall,
convective details remain quite uncertain at this range, but the
best threats for severe weather would be Tuesday and Wednesday.
Beyond that, significantly cooler air will lead to limited
instability. In fact, HIGH temperatures on Friday (Aug 1) are
forecast to only be in the low to mid 70s...which is similar to
our forecast LOW temperatures for tonight!
