KEY MESSAGES

Updated at 1234 AM CDT Sat May 23 2026

- Areas of dense fog overnight into early Saturday morning, mainly in far northwest Arkansas.

- Another round of showers and storms expected late tonight into Saturday. After a relative lull Sunday and Monday, near daily rain 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 Saturday) Issued at 1137 PM CDT Fri May 22 2026

Areas of dense fog have already developed across parts of far northwest Arkansas late this evening, and have issued a dense fog advisory for this area through early Saturday morning. Increasing cloudiness towards sunrise will likely limit the duration of the dense fog Saturday morning.

The next round of showers and thunderstorms is already taking shape across southwest Oklahoma, and this activity will spread northeast across much of eastern Oklahoma and eventually northwest Arkansas late tonight and Saturday morning, with a gradual weakening with eastward extent into Arkansas. Locally heavy rainfall will be the main threat with these showers and storms, with only a very low chance for an isolated strong to severe storm in our area.

Precipitation will taper off Saturday afternoon, and some sunshine will allow temperatures to warm into the 70s to lower 80s.

LONG TERM

(Saturday Night through Friday) Issued at 1137 PM CDT Fri May 22 2026

There will be a relative lull in shower and storm chances Sunday and Monday, although a few mainly afternoon showers and storms may still develop from southeast Oklahoma into western Arkansas each day. Shower and storm chances will increase again Tuesday and Wednesday as an upper level low tracks north from Texas across Oklahoma. Shower and storm chances will continue late in the week as general troughing aloft persists over the southern plains. Slow moving storms will maintain the threat of locally heavy rainfall through the week. Temperatures through the week will generally remain near the seasonal averages for late May.

AVIATION

(06Z TAFS) Issued at 1234 AM CDT Sat May 23 2026

Areas of dense fog expanding through northwest AR will bring several hours of IFR/LIFR conditions there through around 12z when clouds increase ahead of approaching convection. VFR conditions prevail across eastern OK, with exception of some patchy fog around KBVO early. Showers and thunderstorms will move into eastern OK a little before 12z with deteriorating flight conditions through late morning. Confidence in storms maintaining into western AR is a bit lower, but should see at least scattered activity moving through during mid morning into early afternoon. Conditions improve from the west during the afternoon with VFR returning through the end of the period.
