KEY MESSAGES

Updated at 616 AM CDT Sun May 24 2026

- Areas of dense fog are possible Saturday night and Sunday morning across portions of eastern Oklahoma and northwest Arkansas.

- After a relative lull Sunday into Monday, near daily rain chances are expected this week. Locally heavy rainfall and localized flash flooding will be the main threats.

- Temperatures remain near average for much of the week.

SHORT TERM

(Through Sunday) Issued at 1140 PM CDT Sat May 23 2026

Showers and thunderstorms which produced heavy rainfall in NW AR Saturday evening have weekend significantly, with only a few light showers remaining. A slight chance of rain persists early tonight, but precipitation will become increasingly sparse and focused to the east of the area. Short term guidance suggests at least patchy fog development will be possible for much of the FA overnight/Sunday morning, with the greatest potential across NE OK into NW AR. Fog may become dense with visibilities less than one mile, especially in areas which received heavy rains Saturday. After fog dissipates Sunday morning, mostly quiet and predominantly dry conditions are likely for the remainder of the day. High temperatures generally remain within a few degrees of 80 with light NE winds.

LONG TERM

(Sunday Night through Saturday) Issued at 1140 PM CDT Sat May 23 2026

Dry conditions persist Sunday night into the first part of Monday before an upper low gradually lifts northward out of Texas/Louisiana. This will provide increasing rain and storm chances across SE OK and into W-Central AR Monday afternoon and evening. The low continues to lift north through E OK and W AR on Tuesday, providing shower and thunderstorm chances for the entire forecast area, with the highest QPF across our AR zones. A shortwave then rotates through the region Wednesday and Thursday, keeping PoPs elevated areawide. By late week, an omega blocking pattern develops across the northern states with low pressure aloft tending to linger across the Southern Plains. This will keep daily rain and storm chances in the forecast through next weekend. While generally weak wind shear will help keep severe weather chances low through much of the extended period, heavy rainfall and flash flooding potential will continue to be a concern. Temperatures remain near average for the next several days.

AVIATION

(12Z TAFS) Issued at 616 AM CDT Sun May 24 2026

Fog and stratus will continue to significantly impact flight conditions from southeast OK through northwest AR at the beginning of the forecast period, with IFR/LIFR common through about 14z. Quick improvement should follow. Fog will be more patchy in nature across northeast OK. Outside of early this morning, VFR conditions will prevail, with lower potential for fog tonight.
