KEY MESSAGES

Updated at 1055 AM CDT Fri Aug 14 2026

- Very Hot conditions continue through the weekend. - The breezy and hot weather will result in some increase in wild fire risk today and Saturday. Drying vegetation and and timber support this potential in both wooded and grass areas.

- A weak front will move into the area late Sunday and Monday. This will result in a few thunderstorms developing near and north of I-40, with a little lower temperatures Monday. Higher humidity around the front will tend to offset any reduction of the heat. This minor tweak to the pattern does not reflect the potential for a significant cool down through the middle of next week.

SHORT TERM

(Through tonight ) Issued at 1055 AM CDT Fri Aug 14 2026

Temperatures late this morning have been running a few degrees cooler in eastern Oklahoma as compared to yesterday, with values about as we saw 24 hours ago in northwest Arkansas. Dew points are up 2 to 4 degrees higher in far southeast Oklahoma, and about the same or a couple of degrees lower than yesterday elsewhere. Overall temperatures / heat index values will be near or a little lower than yesterday, but still at Heat Warning criteria in much of northeast Oklahoma, and near that criteria at some northwest Arkansas locations. A Heat Advisory remains in effect for areas outside the warning.

LONG TERM

(Tomorrow through Friday) Issued at 1055 AM CDT Fri Aug 14 2026

The forecast trends remain unchanged with the large upper-level high over the region shifting westward a bit and flattening so that one or more upper-level disturbances can brush the area late Sunday and Monday. Depending on storm coverage and associated clouds, temperatures ahead of the front on Sunday could get back near the highest readings of this heat wave before moderating a bit with the front and some extra clouds. Any reduction in temperature with the front will be offset some by an increase in humidity.

The heat is expected to build again starting on Tuesday. There is still no strong signal for a major change to our weather pattern through the middle of next week.

AVIATION

(00Z TAFS) Issued at 626 PM CDT Fri Aug 14 2026

VFR conditions continue through the period. Winds will continue to be the main aviation impact over the region. Gusty southerly winds will subside after sunset with areas of LLWS across NE OK sites during the overnight hours. Wind gusts come back up around 20 to 25 knots by mid morning Saturday for most terminals.
