KEY MESSAGES

Updated at 1235 AM CDT Mon Jul 27 2026

- Dangerous heat conditions continue through at least Tuesday.

- Potential minor cool down and some chance of showers and storms from mid to late week.

SHORT TERM

(Through Monday) Issued at 1123 PM CDT Sun Jul 26 2026

Upper ridge firmly in control with dangerous heat continuing on Monday. Dewpoints are likely to trend a few degrees drier but temperatures will likely be warmer. Heat index values may be near or slightly below exact criteria but persistent wet bulb globe temps at extreme levels coupled with the ongoing duration of the heat warrant the warning from NE OK into west central AR.

LONG TERM

(Tuesday through Sunday) Issued at 1123 PM CDT Sun Jul 26 2026

Dangerous heat expected again Tuesday before a minor cool down by Wednesday. Convection will approach the forecast area by Tuesday evening but struggle to make a more southward advance. A weak cold front will gradually push south and westward into the forecast area and become a zone for a chance of showers and storms Tuesday night into Wednesday primarily across far E OK and NW AR.

Temperatures and dewpoint trends along and west of the weak boundary will be challenge as potential for moisture pooling may offset the minor cool down and still result in excessive heat index values on Wednesday.

The overall pattern will see the upper ridge become centered more westward by late week and temperatures will likely trend toward more seasonal normals. There could also be an increase in shower and storm chances the region aligns on the periphery of the upper ridge but uncertainty remains high.

AVIATION

(06Z TAFS) Issued at 1235 AM CDT Mon Jul 27 2026

VFR conditions are likely to persist through the forecast period for all sites. Light south winds will prevail through the overnight hours before increasing out of the south-southwest during the late morning and afternoon. Mostly clear skies overnight will give way to FEW to SCT mid and high cloud during the day. No precipitation is expected.
