KEY MESSAGES

Updated at 523 AM CDT Fri May 8 2026

- Potential for strong-severe storms on Friday and Saturday evening & night.

- Heat returns next week.

NEAR TERM

(Through Friday) Issued at 125 AM CDT Fri May 8 2026

A low amplitude trough will drop south and southeast through the Plains today with associated surface front. This front is expected to move into northern Oklahoma around midday and then make its way southeast through the afternoon and evening hours. Meanwhile, a sharpening dryline will take shape across southwest Oklahoma southward into western north Texas. Ahead of the front surface temperatures will warm into the 80s with some lower 90s to the west of the dryline.

Although surface moisture return is modest at best, sufficient convergence along the front and possibly the dryline, steep mid- level lapse rates, contributing to CAPE values ranging from 500- 2000J/kg and lift from the trough should support at least scattered thunderstorm development by mid-afternoon across northern Oklahoma. Main hazards will be damaging wind gusts and large hail. As these storms move toward the Red river by early evening there remains some differences in the CAMs with regards to the strength of the storms. The models with less moisture and the loss of daytime heating would suggest a decrease the overall severe threat. However, others are able to tap into this better moisture and keep surface inversion from deepening and maintain storm strength well into the evening as the storms move south of the area.

SHORT TERM

(Friday night through Sunday night) Issued at 125 AM CDT Fri May 8 2026

By Saturday, the front, located across northern Texas, will begin to wash out and south winds will return to the area from west to east through the afternoon hours. Meanwhile, another upper trough and embedded shortwave will approach the central and southern Plains late Saturday afternoon and Saturday night. Much of the day Saturday should remain dry.

The south winds will try and bring better moisture northward and a dryline will take shape by late Saturday afternoon across far western Oklahoma and western north Texas. It not out of the question to see an isolated late day storm or two there. Otherwise, we may see some high-based storms develop late in the day across southwest Kansas and then move southeast with the upper shortwave and surface front. Again, initially damaging winds will be the main risk. As this activity continues to move farther south and east it should encounter somewhat better moisture and become more of a wind and hail risk overnight Saturday with some low end severe lingering into Sunday morning. All this activity will move slowly southeast across the area and could linger in the south Sunday afternoon.

In the wake of the front some cooler temperatures are expected Sunday with plenty of cloud cover. Skies should clear late in the day Sunday across the north and then across the remainder of the area Sunday night, with overnight lows in the 40s north of I-40 and lowers 50s farther south.

LONG TERM

(Monday through Thursday) Issued at 125 AM CDT Fri May 8 2026

Upper ridging then broadens from the southwest CONUS out into the central and southern Plains as we go into early next week. There is a front that the models moves into at least northern Oklahoma on Tuesday with a 850MB thermal ridge to the south of the front. This will make for a very warm day Tuesday, especially across the west and southwest where afternoon temperatures climb to near 100 degrees. This front should wash out rather quickly with south winds returning Wednesday across the west, keeping the hot temperatures entrenched across the west through much of next week with only minimal rain chances.

AVIATION

(12Z TAFS) Issued at 523 AM CDT Fri May 8 2026

All terminals should remain in a VFR category at least through 18Z with brief periods of MVFR conditions due to potential convection. Thunderstorms could fire up along/east of a cold front that will start pushing into northwest Oklahoma beginning 18Z and a few of these isolated convective cells could become strong to severe producing large hail and damaging wind gusts. Storm probabilities are high enough for TEMPO groups between 18-21Z at terminals KPNC & KSWO and most likely impacting terminals in central & southern Oklahoma and KSPS closer to 00Z through 04Z. So far not expecting any storms to impact our farthest western terminals KCSM & KWWR. Should any storms move over any of these terminals they could reduce to an MVFR category for short periods mainly due to lowered visibilities in rain and brief lowered ceilings. Surface winds will be increasing south- southwesterly at 10-15 kts and by 15Z gusting 15-25 kts when late morning mixing begins. The cold front will be shifting surface winds out of the north between 19-23Z at terminals KWWR & KCSM but the front is expected to wash out after 00Z with surface winds going light & variable. However should there be any convective activity then cannot rule out any storm outflow boundaries which could result in more gusty variable winds.
