.SHORT TERM...
(Through Friday)
Issued at 1135 PM CDT Thu Sep 3 2026

After a slightly "less hot" day in many places Thursday,
temperatures will increase once again Friday, with afternoon highs
ranging from 98 to 103 degrees. Afternoon heat index values will
reach or exceed 105 within the current heat advisory area, and
reach 100 to 104 in the rest of the forecast area.

.LONG TERM...
(Friday Night through Thursday)
Issued at 1135 PM CDT Thu Sep 3 2026

There is no real relief from the unseasonable heat in sight, with
widespread triple digit highs expected to persist through at least
much of next week. Heat headlines will be needed for most if not
all of the forecast area from Saturday into next week, and a few
spots may see heat index values peak near or just above 110
degrees on some afternoons. Isolated diurnal showers or
thunderstorms may occur just about any afternoon Saturday through
early next week, especially over the higher terrain areas, but any
rainfall will be brief and only provide temporary heat relief.
Gusty winds will be possible with any storm that may occur. The
rain chances at any one location remain below mentionable levels
at this time. Record or near record high temperatures will be
likely much of next week.
