.SHORT TERM...
(Through tonight )
Issued at 1213 PM CDT Sun Jul 12 2026

Shower and thunderstorm chances will continue across southeast
Oklahoma and west central Arkansas this afternoon, with rain
chances shifting into far southeast Oklahoma by this evening and
overnight. Overnight low temperatures will range from the mid 60s
to lower 70s.

.LONG TERM...
(Tomorrow through Sunday)
Issued at 1213 PM CDT Sun Jul 12 2026

A few showers and thunderstorms will remain possible Monday and
Tuesday across parts of southeast Oklahoma, otherwise dry weather
with near to slightly below normal temperatures will prevail. An
easterly wave tracking west to the south of a strong upper level
ridge over the northern U.S. will increase shower and storm
chances Wednesday across much of the area, with temperatures
remaining near or slightly below normal.

By late week through next weekend, the upper ridge will shift more
to the south and southeast, resulting in a return to hot and dry
weather to eastern Oklahoma and northwest Arkansas. As has been
the case much of the summer thus far, the NBM may be a bit too hot
towards the end of the forecast period, But it will be hot
regardless, with afternoon heat index values back up into the
triple digits in most places by next weekend.

(18Z TAFS)
Issued at 1243 PM CDT Sun Jul 12 2026

Scattered thunderstorms will remain possible through the
afternoon and early evening, potentially impacting KMLC and, to a
lesser extent, KFSM. Storms this afternoon may produce locally
gusty and erratic winds. A few isolated showers could also develop
across NW AR, but no impacts are expected at this time.
Precipitation chances decrease by late this evening and become
increasingly focused to areas along the Red River. Otherwise,
diurnal cu has developed and will persist for the next several
hours, perhaps briefly producing MVFR cigs before lifting this
afternoon. Guidance suggests some potential for fog development
and reduced vsbys early Monday morning, mainly across SE OK and
W-Central AR. Aside from these factors, VFR conditions are likely
to persist through the forecast periods with light winds.
