What happened

The episode as NWS TSA wrote it up.

A slow-moving upper level storm system moved into the Plains on May 23rd and 24th. Very moist and unstable air was in place ahead of this system, which supported several rounds of thunderstorms over eastern Oklahoma. Widespread heavy rainfall resulted in moderate flooding of the Deep Fork River near Beggs. Additional heavy rain events during late May resulted in the continuation of the flood into early June.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

..UPDATE...

DISCUSSION...
UPPER LOW CONTINUES TO SLIDE SOUTHEAST INTO NORTH CENTRAL ARKANSAS
THIS EVENING PER LATEST WATER VAPOR IMAGERY. IN RESPONSE...MOSTLY
CLOUDY CONDITIONS REMAINED OVER NORTHWEST ARKANSAS...WHILE SKIES
BECAME MORE SCATTERED OVER EASTERN OKLAHOMA. OUT TO THE WEST A
DEVELOPING MCS OVER EASTERN COLORADO/WESTERN KANSAS WAS BEGINNING

CURRENT SCATTERING OF CLOUD COVER AND EXPECTED LOW TEMPS IN THE
50S FORECAST TO REACH CLOSE TO THE DEWPOINT TEMP...WILL ADD PATCHY
FOG FOR LOCATIONS MAINLY ALONG AND NORTH OF I-40. SOME ISOLATED

A RIDGE OF HIGH PRESSURE IS FORECAST TO BUILD OVER THE SOUTHERN

THE PLAINS.

EMERGENCY MANAGEMENT PLANNING STATEMENT...

WEEK...ESPECIALLY IN LOCATIONS WHERE AREA LAKES ARE NEAR...OR
OVER FULL CAPACITY. ALSO...MANY MAIN STEM RIVERS WILL CONTINUE TO
REMAIN IN FLOOD. THE RIVERS THAT HAVE BEEN IN A PROLONGED PERIOD
OF AT LEAST MODERATE FLOOD WILL BE SLOWER TO RESPOND...AND WILL
REQUIRE ADDITIONAL TIME TO RESTORE LEVELS BELOW FLOOD STAGE.
