KEY MESSAGES

Updated at 640 PM CDT Fri May 22 2026

- Chances for showers and storms will continue this afternoon into Saturday. After a relative lull Saturday night and Sunday, near daily chances are expected next week. Locally heavy rainfall will be the main threat.

- Temperatures warm back to near normal for much of the next week.

SHORT TERM

(Through tonight ) Issued at 1249 PM CDT Fri May 22 2026

A mid-level low pressure/MCV evident on radar imagery southwest of FSM is what is left over from the rains last night. The system is now on the move toward the east. Scattered showers and storms can be expected through the afternoon within the broader trough aloft over far E OK into W AR. Focus then shifts out west. The HRRR has shown a consistent signal of storms coming out of the southern TX Panhandle/South Plains area this afternoon, growing upscale into an eastward moving MCS in the vicinity of the Red River tonight. This activity would not move into SE OK until after midnight, reducing the severe threat. Nonetheless, gusty winds and locally heavy rainfall would accompany this system as it moves across SE OK late tonight into Saturday morning. Farther north, storms may also fire along a cold front over western KS/NW OK this afternoon, with some of this activity moving into NE OK tonight.

Skies may clear out enough in the wake of the MCV in the east tonight to allow for some fog development, especially in the valleys of NW/W-C AR and far E OK.

LONG TERM

(Tomorrow through Friday) Issued at 1249 PM CDT Fri May 22 2026

An MCV left over from the MCS tonight is likely to fire off more scattered shower and storm activity over eastern portions of the forecast area on Saturday. Once that system clears Saturday evening, there should be a relative lull in convective activity Saturday night and Sunday. On Monday, an upper low is expected to lift north from TX, with afternoon shower and storm chances increasing first over southern and eastern areas that afternoon. Higher shower and storm coverage is expected areawide on Tuesday as the system moves overhead. By the middle of next week, a weakness is maintained in the mid-level height fields over the region south of an omega block in the higher latitudes, and that is expected to persist through the end of the week. Daily shower and storm chances are expected, peaking during the afternoon hours.

With weak flow aloft, severe potential will be pretty low. However, slow-moving storms could drop locally heavy rainfall and lead to isolated flash flooding.

AVIATION

(00Z TAFS) Issued at 640 PM CDT Fri May 22 2026

VFR conditions likely persist this evening across the area, though some brief MVFR cigs remain possible across NW AR before diurnal cu decreases. Overnight into Saturday morning, guidance continues to produce fog and limited vsbys across NW AR sites and potentially BVO. TEMPOs were maintained to cover this potential, with IFR to LIFR vsbys possible. A complex of showers and thunderstorms is forecast to move east into the area during the morning hours, with precip potential lingering into the afternoon, especially across NW AR. MVFR ceilings are forecast as this activity moves into E OK sites between 12 and 16z. By mid to late afternoon, all sites are expected to return to VFR category.
