KEY MESSAGES

Updated at 1151 AM CDT Mon Aug 10 2026

- Hot and dry weather will persist through the workweek. A Heat Advisory is in effect for much of E OK and W AR today and Tuesday. Additional heat headlines are likely this week.

- Very low rain and storm chances will be confined to areas near the Kansas and Missouri borders late this weekend.

SHORT TERM

(Through tonight ) Issued at 1151 AM CDT Mon Aug 10 2026

Dangerous heat continues today with heat indices up to 109 for many locations across E OK and NW AR. A Heat Advisory remains in effect until 8 PM for most of the area. Quiet conditions are likely tonight with mostly clear skies. Low temperatures will be quite warm again in the mid to upper 70s with south winds persisting overnight, especially across E OK.

LONG TERM

(Tomorrow through Monday) Issued at 1151 AM CDT Mon Aug 10 2026

The upper level ridging pattern will fluctuate in the coming days but the end result for our area is more or less the same: hot and dry. Ridging thus far has been centered over the four corners region and across the SE U.S. with positive height anomalies remaining in place between the two. As we move into mid-late week, western ridging will tend to shift east and merge with the SE ridge. This opens the door for a weak cold front to move into the central Plains towards our CWA. However, latest guidance has continued to suggest the front will remain north of us with fewer sensible impacts for E OK and NW AR. Model output does indicate at least a slight chance of rain near the KS and MO borders late this weekend, but overall dry conditions are forecast to continue.

In the lower levels, lee troughing will provide persistent south- southwest winds over the coming days. These winds will become breezy during the afternoon hours and do not fully dissipate overnight. With this orientation, we should see dewpoints mix out more than previous days, especially mid to late week. However, temperatures will also increase slightly during this time. Overall, afternoon temperatures near/above 100 and maximum heat index values greater than 105 will remain likely for much of the area. Based on trends so far this morning and Sunday afternoon, have issued a Heat Advisory for the same areas on Tuesday. Additional heat headlines are likely over the coming days. Please continue to take precautions to stay safe when outdoors this week.
