KEY MESSAGES

Updated at 1136 AM CDT Sun Aug 9 2026

- Hot and dry weather will persist through the week. A Heat Advisory is in effect for portions of eastern Oklahoma, northwest and west- central Arkansas Today and Monday. Additional heat headlines are likely in the coming days.

- Any rain or storm chances will be confined to areas near the Kansas and Missouri borders late Friday and again Saturday night.

SHORT TERM

(Through tonight ) Issued at 1136 AM CDT Sun Aug 9 2026

The mid level ridge continues to hold strong near the Four Corners through tonight resulting in dry and seasonably hot conditions. The Heat Advisory remains in place this afternoon for portions of eastern Oklahoma and northwest and west-central Arkansas with some locations likely exceeding 110F for a short time. Meteograms from yesterday indicated generally brief, less than 2 hour, length of warning criteria precluding the need to upgrade. South- southwest winds will be gusty this afternoon as a lee trough deepens across the High Plains.

LONG TERM

(Tomorrow through Sunday) Issued at 1136 AM CDT Sun Aug 9 2026

The subtropical ridge gradually expands westward across the southeast U.S. this week as a trough deepens along the west coast by Wednesday. This will result in the ridge axis remaining in the vicinity with the subtropical high center shifting to along the Gulf Coast late in the week. With the ridge firmly overhead expect continued hot conditions with triple digit heat across much of eastern Oklahoma and near triple digits elsewhere through the forecast period. The ensemble model trend has been for any late week rain chances to shift more north with time as the ridge repositions itself to the southeast. Therefore, continued worsening of drought and fire weather conditions are expected. With mid level height fields rising into the 95th+ percentile relative to climatology by next weekend there are no real indications of relief in the near term.

AVIATION

(12Z TAFS) Issued at 615 AM CDT Sun Aug 9 2026

VFR conditions are likely to persist through the forecast period for all sites. Aside from some passing high clouds and SCT afternoon cu development, mostly clear skies are expected. Breezy WSW winds likely this afternoon, especially across NE OK, where gusts near 20 kts will be possible. Winds decrease through the overnight hours before increasing again out of the southwest late Monday morning.
