KEY MESSAGES

Updated at 548 AM CDT Mon Jun 29 2026

- Low chances of thunderstorms across far western Oklahoma during the evening hours through mid-week; strong winds possible.

- Increasing heat and a slight chance of showers and thunderstorms toward end of the week into next weekend.

NEAR TERM

(Through Monday) Issued at 157 AM CDT Mon Jun 29 2026

A strong low-level jet has developed over western KS and northwest OK overnight as a trough approaches the Rockies, and this has led to breezy south winds with strong wind gusts of 40 mph or higher for several of our western observation stations earlier this evening (and prior to the BL decoupling). Some areas could see this recur after sunrise and as the BL begins to mix, but not anticipating these gusts to last more than a few hours.

Other than breezy southerly winds today, will see scattered high clouds stream in from the southwest. With abundant low-level moisture still present (especially east of I-35), high temperatures will rise into the low 90's there and into the mid-90's across central Oklahoma. For areas generally west of Hwy 81, peak readings near 100 deg are possible. Overall, heat index values will be lower today with the highest values (near 105) expected over portions of north-central Oklahoma.

Scattered thunderstorms could develop once again this afternoon and evening near the dryline (west of the 100th meridian) and a few decaying storms may reach our western counties by late evening with strong to isolated severe wind gusts.

SHORT TERM

(Monday night through Wednesday night) Issued at 157 AM CDT Mon Jun 29 2026

Storm activity may continue until after midnight out west, but this model solution is an outlier and will have to watch model trends. Low storm chances return each evening through Wednesday night over northwest and western Oklahoma, though severe weather is not expected.

Otherwise, hot, dry, and breezy conditions are expected with scattered mid- and high-clouds. Heat index values are expected to be lower than those seen the past few days.

LONG TERM

(Thursday through Sunday) Issued at 157 AM CDT Mon Jun 29 2026

High temperatures trend upward Thursday through Saturday as mid-level heights rise with the expansion of the ridge across the southern two- thirds of the country. Highs of 100 to 105 degrees are forecast to be widespread by July 4th with low chances of showers and thunderstorms returning late Friday and into the weekend. A cold front could move into northern Oklahoma late Saturday or early Sunday which will dial down the intensity of the heat just a bit on Sunday.

AVIATION

(12Z TAFS) Issued at 548 AM CDT Mon Jun 29 2026

All terminals expected to stay in a VFR category through the forecast period. There is some stratus forming between the cities of Lawton to near Oklahoma City proper so will TEMPO both terminals KOKC & KOUN for a potential but brief MVFR category ceiling through 14Z. Will keep low-level wind shear conditions across all our terminals through 15Z due to a strong low-level jet overhead. Surface winds will stay gusty from partial mixing into the low- level jet and expecting them to veer slightly more south- southwest by 14Z. By 14Z wind speeds will be sustained around 20 kts while higher mixing will result in 30-35 mph gusts through the afternoon. By 01Z expecting surface winds to back slightly more southerly although not expecting them to completely decouple from the low-level flow staying gusty overnight around 20-25 kts. Another strong southerly low-level jet at 40-50 kts will be developing overnight by 06Z with low-level wind shear conditions returning across all of our terminals.

There will be a chance for thunderstorms developing on the Southern High Plains late this evening after 02Z which could impact far western Oklahoma. However probabilities are too low at this time to be mentioned in the forecast for terminals KCSM & KWWR but is worthy of at least being mentioned in this discussion.
