KEY MESSAGES

Updated at 1253 AM CDT Thu Jun 25 2026

- Strong to severe storms are possible on Friday, with hail up to the size of quarters, gusts to 70 mph, and locally heavy rainfall possible.

- Hotter and drier into the weekend and the week beyond.

NEAR TERM

(Rest of tonight through Friday) Issued at 1253 AM CDT Thu Jun 25 2026

A positively-tilted stationary front is anticipated to remain over parts of the area today along with remnant outflow boundaries from recent convection, along with a weak surface low prog'd to be near Childress by afternoon. Showers and thunderstorms remain possible through tonight.

Strong instability (highest south of the boundary) and eroding MLCIN will lead to an environment favorable for strong to severe storms, especially towards late afternoon and evening as wind shear increases. Highest chances are this afternoon into the evening hours across north- central, western and west-central Oklahoma, and adjacent north Texas. Marginal mid-level lapse rates should limit hail size to around quarter- sized. Higher downdraft CAPE (up to 1500 J/kg or so) across southwest Oklahoma and western north Texas will lead to a favorable environment for severe wind gusts up to 70 mph. As has been the case this past week, high PWAT values will continue to be present which could result in efficient rainfall, as well. Flash flood potential should be limited mainly to north-central Oklahoma from a line near and west of Blackwell to Perry given 5-day rainfall totals of near 7.5 inches at the Blackwell mesonet site.

SHORT TERM

(Friday night through Saturday night) Issued at 1253 AM CDT Thu Jun 25 2026

Severe potential diminishes by late Friday evening but another wave of scattered showers/storms could move into northwest/western Oklahoma late Friday evening into early Saturday morning with strong to severe wind gusts possible.

The upper ridge that was centered over Chihuahua shifts eastward across Texas and reaches the lower Mississippi River Valley by Sunday morning. Meanwhile, an upper trough descends across the Pacific northwest and will see the beginning of a pattern change as upper flow shifts southwesterly. There are low chances of showers and storms on Saturday, but are nonexistent by Sunday. Otherwise, summertime heat is expected.

LONG TERM

(Sunday through next Thursday) Issued at 1253 AM CDT Thu Jun 25 2026

Above-average temperatures will be the main story next week with highs in the upper 90's to low 100's. Heat index values are forecast to remain just below advisory criteria, with warmer values expected over north-central Oklahoma into mid-week. Low shower and storm chances could linger across western Oklahoma and adjacent north Texas.
