What forecasters said that day

The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Tulsa, OK wrote its last area forecast discussion before this flash flood watch went out at Apr 28, 2:42 PM CDT, 8 minutes earlier.

Area forecast discussion, Apr 28, 2:42 PM CDT, 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE Tulsa OK
242 PM CDT THU APR 28 2016

.DISCUSSION...
Low level moisture starting to lift back north out of southeast
Texas this afternoon ahead of upper low currently moving through the
desert southwest. Low level jet will begin to increase across north
Texas and southeast Oklahoma tonight as upper low moves into the
four corners region by 12z Friday. In response, elevated strong
thunderstorms will likely develop/spread north into southeast
Oklahoma late tonight. This activity will continue across the
remainder of eastern Oklahoma and northwest Arkansas Friday
morning with a damaging wind/large hail threat. Along with the
severe threat, locally heavy rainfall will be likely, especially
across southeast Oklahoma and west-central Arkansas south of
Interstate 40. Given the relatively low flash flood guidance, a
flash flood watch will be issued for aforementioned area.

Overall tornado threat will likely depend on how far north warm
front lifts into southeast Oklahoma Friday afternoon. If the
morning convection is too widespread or lingers into the afternoon
hours, the warm front would likely remain further south near the
red river. Any breaks in the thunderstorm activity would allow for
sufficient destabilization to support supercell thunderstorms
given the increasing deep layer shear. In addition, any residual
boundaries would support an enhanced tornado threat, especially
given the low LCL heights expected. Regardless, a severe/heavy
rainfall threat will continue Friday evening into the overnight
hours as the main upper low lifts into the central plains.

Thunderstorm should be begin to shift east of the region Saturday
morning. A few lingering widely scattered thunderstorms will be
possible across far eastern Oklahoma and northwest Arkansas
Saturday afternoon before the cold front sweeps through Saturday
evening.

Cool conditions expected Sunday into the early part of next week as
surface high pressure builds over the region with temperatures
remaining near or below normal.

DISCUSSION...

THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS NORTHEAST TEXAS AFTER
MIDNIGHT TONIGHT. LARGE HAIL WILL BE THE PRIMARY THREAT AS THE
STORMS MOVE INTO SOUTHEAST OKLAHOMA THROUGH DAYBREAK.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
ACTIVATION OF THE REGIONAL SPOTTER NETWORK LIKELY.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
FRIDAY...SEVERE THUNDERSTORM POTENTIAL...HEAVY RAIN POTENTIAL.
SATURDAY...SEVERE THUNDERSTORM POTENTIAL.
SUNDAY...NO HAZARDS.
MONDAY...THUNDERSTORM POTENTIAL.
TUESDAY AND WEDNESDAY...NO HAZARDS.

EXTENDED DISCUSSION...

STORMS WILL LIKELY BE ONGOING ACROSS EASTERN OKLAHOMA AND WESTERN
ARKANSAS FRIDAY MORNING. STORMS WILL DEVELOP LATER IN THE DAY TO OUR
WEST AND WILL MOVE INTO OUR AREA DURING THE AFTERNOON AND EVENING.
THE SEVERITY AND TYPE OF SEVERE WEATHER THAT OCCURS WITH THESE
STORMS WILL DEPEND ON HOW FAR NORTH THE WARM FRONT RETREATS. LARGE
HAIL WILL BE THE PRIMARY THREAT ON THE COOL SIDE OF THE
FRONT...WHILE TORNADOES...HAIL AND DAMAGING WINDS WOULD BE POSSIBLE
ALONG AND SOUTH OF THE BOUNDARY. AT THIS TIME...EAST CENTRAL AND
SOUTHEAST OKLAHOMA HAVE THE GREATEST POTENTIAL FOR SEVERE STORMS

IF THE WARM FRONT SETS UP NEAR THE RED RIVER ON FRIDAY...THE SETUP
WOULD FAVOR HEAVY RAINFALL AND POSSIBLE FLOODING POTENTIAL ACROSS
SOUTHEAST OKLAHOMA AS WELL. ONE TO THREE INCHES OF RAINFALL ARE
POSSIBLE.

SEVERE STORM POTENTIAL WILL CONTINUE INTO SATURDAY BUT WILL DIMINISH
FROM WEST TO EAST LATER IN THE DAY AS A PACIFIC COLD FRONT SWEEPS
ACROSS THE AREA.
