KEY MESSAGES

Updated at 443 PM CDT Tue Jun 23 2026

- Severe thunderstorms capable of producing damaging, straight line winds and very heavy rainfall will remain possible this afternoon and into Wednesday morning.

- Chances for evening storms again on Wednesday and potentially Thursday.

- Hotter and drier into the weekend.

NEAR TERM

(Rest of today and tonight) Issued at 223 PM CDT Tue Jun 23 2026

Severe thunderstorms with heavy rainfall will remain possible for much of the area through this afternoon and evening with isolated, damaging straight line winds (75+mph possible) and locally heavy rainfall the primary hazards; there is a very low tornado potential as well. SPC mesoanalysis depicts a large PWAT maxima of 2.2 inches extending across east- central to southern Oklahoma and into parts of southwest Oklahoma and adjacent north Texas. A short-fused Flood Watch was issued earlier for east-central Oklahoma due to anticipated heavy rainfall this afternoon, which is currently ongoing.

Another complex of storms with heavy rainfall may descend from Kansas this evening and during the overnight hours if destabilization can recur over northern Oklahoma, though this is highly uncertain given today's activity. Given the potential, will be extending the current Flood Watch in time and adding north-central and the remaining southern Oklahoma counties.

SHORT TERM

(Wednesday through Thursday night) Issued at 223 PM CDT Tue Jun 23 2026

There is a marginal risk of severe thunderstorms on Wednesday given moderate to high instability and remnant boundaries. Large hail, damaging winds, and heavy rainfall will be possible with any storm development. POPs are on the low side for Wednesday given the high uncertainty of where storms develop and increase towards Thursday morning over north-central Oklahoma or MCS potential from Kansas. Storm chances remain primarily across northern Oklahoma through Thursday night.

LONG TERM

(Friday through Monday) Issued at 141 AM CDT Tue Jun 23 2026

The northwest flow regime will break down by Saturday at the latest. The subtropical ridge will slide back east and amplify across the southeast US in response to a trough approaching the Pacific Northwest. For us, there are a few sensible impacts:

-Temperatures will start heating up again by the weekend, and Heat Advisory criteria may once again be met over a 3-5 day span consecutively during the afternoon.

-Rain chances will markedly decrease over the weekend and into early next week, as well.

There is an indication that the upcoming period of ridging will then retrograde and center itself back over the southern/central Plains during week 2, but that is beyond the current long-term forecast.

AVIATION

(00Z TAFS) Issued at 443 PM CDT Tue Jun 23 2026

Expecting a lull with the convection as most terminals return to a VFR category. Two more rounds of MCS could move into our area overnight, the first coming down off the Central Plains between 02-07Z although probabilities will be at 30%. A second round coming off the Central & Southern High Plains after 09Z will likely impact 2 of our terminals in western & northwest Oklahoma but lower probabilities of 30% for our remaining terminals. Although periods of MVFR & IFR conditions possible under these potential storms due to lowering ceilings and/or reduced visibilities in rain. By 18Z any storm probabilities should end with all terminals in a VFR category through the next 6 hours.
