The radar

The Tulsa radar (KINX), 99 km from the middle of the area, began a volume at 05:28 UTC, the scan nearest the moment this went out.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Springfield, MO (KSGF), launched 00:00Z, 5.4 hours before the alert went out and 83 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

.SHORT TERM...
(Through tonight )
Issued at 1226 PM CDT Fri Jun 26 2026

A boundary extends from an area of low pressure over the TX
Panhandle along the OK/KS border region and into the Ozarks of
Missouri. The boundary is slowly sagging south and is expected to
focus convection over NE OK and SW MO, possibly into far NW AR,
this afternoon with increasing coverage into the evening. Some
additional warm advection storms are also expected overnight,
mainly north of the boundary. Slow-moving and/or training storms
in a high PWAT environment will have the potential to drop
locally high-end totals somewhere across NE OK and far NW AR
through Saturday morning. CAMs suggest potential for isolated 3 to
7 inch amounts. With the soils already fairly saturated, most of
this rainfall is likely to become runoff, leading to rapid-onset
flash flooding. Some main- stem river flooding is also possible.
The going Flood Watch has been extended in time to 7 AM Saturday,
and expanded in area to include Benton and Carroll counties in AR
near the MO border.

Deep-layer shear is weaker today, so a more organized severe
weather event is not expected. However, storms may certainly
become severe at least briefly, with the primary threat being
locally damaging wind. Marginally severe hail is possible. The
severe threat will peak during the afternoon and into the early
evening hours, dropping off overnight.

.LONG TERM...
(Tomorrow through Friday)
Issued at 1226 PM CDT Fri Jun 26 2026

There will be some chance for storms into Saturday morning as
whatever is left coming off the High Plains this afternoon comes
east. It is possible than an MCV forms and helps to keep the
activity going farther east. While the potential for heavy
rainfall will be dropping by this time, any additional rains on
top of areas hit hard tonight could lead to more flooding. By
Saturday afternoon, low pressure developing over northeast CO will
draw the boundary north and away from the region, as upper heights
rise with the building ridge downstream from the western CONUS
trough. This will bring an end to the recent wet regime, and we
will make an abrupt shift toward hot, humid and dry weather as we
head into next week. While a few spots could get close to advisory
criteria along the highway 75 corridor in NE OK as soon as
tomorrow afternoon, the afternoon heat index forecast leans toward
Monday as the first day of what could be several days in a row of
heat headlines next week.

Ensemble means place the H5 ridge center initially over the
Mississippi Valley with a shift toward the Ohio Valley as we head
deeper into next week. Daily storm chances along the lee trough
will stay out west, while moisture will begin to increase from the
southeast on the back side of the ridge. Some low chances for
mainly afternoon terrain-enduced showers and storms are possible
beginning the middle of next week. By next weekend, ensemble data
has the ridge retrograding over our area and then to our west with
very little in the way of rain chances.

.AVIATION...
(06Z TAFS)
Issued at 1221 AM CDT Sat Jun 27 2026

VFR conditions will prevail through the period outside of
thunderstorm impacts. Ongoing storms located over central OK will
eventually expand into part of northeast OK over the next few
hours and ultimately into northwest AR after 09z. IFR conditions
can be expected within storms along with gusty and erratic winds.
Showers and storms will decrease from the west Saturday morning
with decreasing clouds and gusty south winds through the day.

This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...This Afternoon and Tonight.

SEVERE THUNDERSTORM.
	RISK...Limited to Elevated.
	AREA...Northeast Oklahoma and far Northwest Arkansas.
	ONSET...Ongoing...waning after midnight.

FLASH FLOOD.
	RISK...Elevated to Significant.
	AREA...Northeast Oklahoma and far Northwest Arkansas.
	ONSET...After 7 PM.

	AREA AT GREATEST RISK...Along and north of highway 412.

DANGEROUS HEAT.
	RISK...Limited.
	AREA...Eastern Oklahoma.
	ONSET...Ongoing.

DISCUSSION...

Numerous storms are expected to develop near a boundary across
northeast Oklahoma and northwest Arkansas. Some storms may become
severe with damaging winds and large hail the main threats.

Intense rain rates from slow-moving and/or training storms will
yield elevated to significant flash flood potential tonight.
Locally high-end rainfall totals are possible, in the 3 to 7 inch
range. With soils fairly saturated, most of this rain will likely
be runoff and cause dangerous rapid-onset flash flooding.
Flooding on main-stem rivers is also possible if rains fall in
the right basins.

Heat index values between 100 and 105 degrees are occurring in
spots across northeast Oklahoma, especially in the Arkansas River
Valley. Conditions will improve after sunset this evening.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.
SATURDAY...Thunderstorm...High Wind...Dangerous Heat Potential.
SUNDAY and MONDAY...High Wind...Dangerous Heat Potential.
TUESDAY...Dangerous Heat Potential.
WEDNESDAY and THURSDAY...Thunderstorm...Dangerous Heat Potential.

EXTENDED DISCUSSION...

Showers and storms may linger into early Saturday before ending.
Hot, humid, and breezy conditions are then expected for the rest
of this weekend through much of next week. Afternoon heat index
values will likely exceed 105 degrees in many places Saturday
through Thursday and heat headlines may be needed across parts of
the forecast area through much of next week. Low thunderstorm
chances may return to the higher terrain of southeast Oklahoma
and northwest Arkansas by the middle of next week.
