The radar

The Western Arkansas radar (KSRX), 71 km from the middle of the area, began a volume at 01:14 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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, 1.2 hours before the alert went out and 118 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.

BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Tulsa OK
814 PM CDT Sat May 23 2026

The National Weather Service in Tulsa has issued a

* Flash Flood Warning for...
  North Central Crawford County in northwestern Arkansas...
  Southeastern Washington County in northwestern Arkansas...

* Until 1115 PM CDT.

* At 814 PM CDT, Doppler radar indicated thunderstorms producing 
  heavy rain across the warned area. Radar estimates between 1.5 and 
  2.5 inches of rain have fallen. Additional rainfall amounts of 1 
  to 2 inches are possible in the warned area. Flash flooding is 
  ongoing or expected to begin shortly.

  HAZARD...Flash flooding caused by thunderstorms.

  SOURCE...Radar.

  IMPACT...Flash flooding of small creeks and streams, urban
           areas, highways, streets and underpasses as well as
           other poor drainage and low-lying areas.

* Some locations that will experience flash flooding include...
  Winslow...                         Brentwood...
  Blackburn...                       Devils Den State Park...
  Mount Gayler...                    Wyola...
  Arnett...                          Durham...

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood 
deaths occur in vehicles.

In hilly terrain there are hundreds of low water crossings which are 
potentially dangerous in heavy rain. Do not attempt to cross flooded 
roads. Find an alternate route.

Flooding is occurring or is imminent. It is important to know where 
you are relative to streams, rivers, or creeks which can become 
killers in heavy rains. Campers and hikers should avoid streams or 
creeks.

Please report observed flooding to local emergency services or law 
enforcement and request they pass this information to the National 
Weather Service when you can do so safely.

.SHORT TERM...
(Through tonight )
Issued at 1227 PM CDT Sat May 23 2026

An MCV left from the storms last night continues to spin over
northeast OK early this afternoon. A band of rain and embedded
thunder extends from the low to the southeast into west-central
AR. The latest runs of the HRRR suggest the MCV and associated
precip will lift slowly northeast through the afternoon and
evening. The latest mesoanalysis shows some destabilization has
occurred north of the area of rain across southeast KS, far
northeast OK and northwest AR. This is where the greatest coverage
of more spotty showers and storms will be, as indicated on radar
mosaic. Additional development is possible further south through
the afternoon as well as environment becomes at least weakly
unstable. Severe weather is not expected owing to insufficient
deep layer shear. Rain/storm coverage should decrease this evening
with a mostly quiet night expected. The latest guidance clears
skies enough across northeast Oklahoma and northwest Arkansas to
allow for fog development toward daybreak Sunday morning.

.LONG TERM...
(Tomorrow through Saturday)
Issued at 1227 PM CDT Sat May 23 2026

The latest CAMs and global models forecast a mostly quiet day on
Sunday, aside from maybe an isolated shower or storm in the
terrain of SE OK and NW AR during the afternoon. Monday will be
quiet for most, with increasing PoPs from the southeast Monday
afternoon and night in association with an approaching upper low
from the ArkLaTex. The upper low will lift N/NNW over the region
on Tuesday, yielding higher areawide PoPs that day. Another wave
will lift north into the area from TX on Wednesday, keeping higher
more areawide PoPs going. A trough of low pressure aloft will
remain over the region through the end of the week, trapped
beneath an omega block in the higher latitudes. Expect daily
rain/storm chances to continue.

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 638 PM CDT Sat May 23 2026

Scattered to overcast mid and high clouds will continue into this
evening over the CWA as an area of low pressure lifts northeast
out of the region. Scattered rain showers along with a low thunder
potential will also remain common for mainly far eastern Oklahoma
and northwest Arkansas into mid evening and then begin to taper
off and exit tonight. Locally heavy rains and gusty winds are
capable within the stronger showers and any storm development.
Overnight tonight into Sunday morning, cloud cover is forecast to
scatter out which will aid the development of fog across parts of
the CWA. Will continue with tempo groups for timing of the greater
potential, with the greater chance of LIFR conditions over far
northwest Arkansas. Conditions should improve after sunrise, with
a few passing mid/high clouds Sunday afternoon. Winds through the
period remain light/variable into Sunday and then become more east
to northeast Sunday afternoon.

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

.DAY ONE...This Evening and Tonight.

SEVERE THUNDERSTORM.
	RISK...Limited.
	AREA...Far Northeast Oklahoma and Far Northwest Arkansas.
	ONSET...Ongoing Through Mid Evening.

HEAVY RAIN AND FLASH FLOOD.
	RISK...Limited.
	AREA...Far Eastern Oklahoma and Northwest Arkansas.
	ONSET...Ongoing.

POOR VISIBILITY.
	RISK...Limited.
	AREA...Northeast Oklahoma and Northwest Arkansas.
	ONSET...After Midnight.

DISCUSSION...
Scattered rain showers along with chances for thunderstorms remain
forecast across parts of eastern Oklahoma and northwest Arkansas
into this evening as an area of low pressure moves through the
region. The greater thunder potential with an isolated to limited
severe threat resides over far northeast Oklahoma into far
northwest Arkansas ahead of the low pressure center. Also, the
slow movement of these showers and storms will create locally
heavy rainfall which could lead to localized flood concerns. This
activity should taper off and exit late evening, with a slight
chance of rain remaining into the overnight hours for parts of
northwest Arkansas.

Late tonight into Sunday morning, patchy areas of fog are expected
to develop mainly within the valleys of northeast Oklahoma and
northwest Arkansas. This fog may be dense in spots and should burn
off shortly after sunrise Sunday.

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

.DAYS TWO THROUGH SEVEN...Sunday through Friday.
SUNDAY...Dense Fog Potential.
MONDAY THROUGH FRIDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Patchy fog may linger into Sunday morning mainly in the valleys
of northeast Oklahoma and northwest Arkansas. This fog may be
dense in spots and will burn off shortly after sunrise. After
a relative lull in the activity Sunday, daily thunderstorm
chances are forecast next week, peaking during the afternoon
hours each day. Organized severe weather is not expected, but
slow- moving storm could drop locally heavy rainfall which could
lead to isolated flash flooding.
