KEY MESSAGES

Updated at 224 AM CDT Sat Jul 11 2026

- Scattered showers/storm early this morning.

- Heat indices 95 to near 105 again this afternoon.

- Storms likely to be more widespread this evening and overnight.

NEAR TERM

(Through Saturday) Issued at 224 AM CDT Sat Jul 11 2026

The band of showers and thunderstorms that moved across the Texas and Oklahoma panhandles has weakened and become less widespread, but scattered showers and isolated thunderstorms have developed across northwestern Oklahoma ahead of this weakening band. These may persist for a few hours before dissipating later this morning.

A cold front moved into northern Oklahoma Friday and has become nearly stationary. The West Texas mesonet also shows an area of weak convergence along a line stretching from Gage OK down toward Lubbock with south winds east of this wind shift to west/northwest winds west of it, although the wind speeds are rather weak. Through today, the front in northern Oklahoma will likely drift slowly south as surface pressure rises in the mid-Mississippi Valley behind a upper level trough moving southeast through that area. By mid afternoon, scattered showers and thunderstorms will likely develop near this front and become more widespread late this afternoon and this evening as the front continues to slowly move south. Strong and isolated severe storms will be possible with relatively dry low-level air supporting strong downdrafts and thunderstorm wind gusts. Hail will be possible as well but warm and low-level dry air suggest melting which will keep the hail threat somewhat in check.

Somewhat cooler temperatures in the north on the other side of the front will be counteracted by higher dewpoints. There is a 5-10 degree increase in dewpoints this morning across northwestern Oklahoma north of the boundary. So heat index values will again be in the 95-105 range throughout the area.

SHORT TERM

(Saturday night through Monday night) Issued at 224 AM CDT Sat Jul 11 2026

Convection is expected to become more widespread this evening near the front as it drifts south before finally before finally decreasing towards sunrise. Gusty winds will still be possible with these storms. The winds through the atmosphere are relatively weak, so storm motions will likely be slow which could lead to locally heavy rainfall. Storms will decrease again toward sunrise Sunday morning. Precipitation chances develop again Sunday afternoon with the highest chances near the boundary which will likely be in southern Oklahoma. Again, strong or isolated severe storms will be possible, with wind being the primary threat.

Heat Index values will again be 95-105 across the area on Sunday afternoon.

Monday's storm chances will depend on evolution of the weather pattern this weekend. The most likely scenario is that the front will have shifted south into Texas and the chances of storms will be lower on Monday than on Saturday/Sunday, but if the front remains closer to the area, storm chances may be a little higher again, most likely in north Texas and southern Oklahoma. But with the expectation that the front shifts south, forecast heat index values may lower slightly Monday afternoon with fewer areas reaching triple digit heat indices.

LONG TERM

(Tuesday through Friday) Issued at 224 AM CDT Sat Jul 11 2026

The weather pattern looks to shift the primary mid-level ridge into an east-west oriented ridge across the northern United States early in the week, with an inverted trough developing through the week from northwest Mexico into eastern New Mexico and west Texas. But the medium-range models differ on how that will affect the placement of the ridge as we get later into the week. So while there is uncertainty on how the pattern will evolve, it generally looks precipitation chances will be relatively low with a warming trend through the week.

AVIATION

(18Z TAFS) Issued at 1207 PM CDT Sat Jul 11 2026

While predominately VFR conditions are expected to prevail through the period, scattered convection by this evening will offer potential for brief category reduction(s).

Thunderstorm coverage is expected to begin early this evening (after 20-22 UTC) across northern Oklahoma and progress slowly southward towards the Red River towards daybreak on Sunday. Gusty and erratic winds and vis reductions are possible in/near storms.

Safe travels!
