KEY MESSAGES

- Dangerous heat stress will remain a concern through late next week.

- Afternoon showers and thunderstorms will be possible over at least portions of the forecast area each day of the forecast period.

DISCUSSION

Issued at 341 AM CDT Sat Aug 8 2026

Patchy fog may be possible in the pre-dawn hours will gradually make way to another day of hot conditions across the area. High pressure in the Four Corners and Bermuda High off the Atlantic Coast will keep our area under a trough pattern over the weekend. Diurnal convection will be possible into the early evening hours. A few storms may be strong to severe; however, widespread severe weather is not expected. Although convection will be possible, dangerous heat will continue to be a concern through the weekend. Heat index values will remain below advisory criteria and will continue to advertise the current "Limited" heat HWO graphic.

Monday through Friday:

The Bermuda High is expected to amplify, expanding the ridge into the southeast region over the week, increasing humidity and heat index values. Highs ranging from the mid to upper 90s along with increasing humidity will cause concern for heat stress. Heat products may be needed mid-week but will be evaluated as days progress. /SW/
