What forecasters said that day

The local office's own words before this flash flood warning 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 warning went out at May 5, 6:26 AM CDT, 15 minutes earlier.

Area forecast discussion, May 5, 6:26 AM CDT, 15 minutes before

Area Forecast Discussion
National Weather Service Tulsa OK
626 AM CDT Sun May 5 2024

...New AVIATION...

.SHORT TERM...
(Today)
Issued at 300 AM CDT Sun May 5 2024

Showers and storms will overspread the area today as
an upper trough axis will lift northeast from TX
into AR and MO tonight. Pockets of heavier rainfall are
likely to occur just about anywhere across the forecast
area through the afternoon. Locally higher rainfall amounts
today and saturated soils from previous convection across
the area will maintain the flash flooding threat. Rain will
begin to taper off from SW to NE this afternoon and evening as
the upper trough lifts through the area. That said, the current
expiration time of 00z Monday for the flood watch looks good and
will leave as is.

&&

.LONG TERM...
(Tonight through Saturday)
Issued at 300 AM CDT Sun May 5 2024

Lingering rain across the NW AR zones should end by 06z, leaving
the forecast area dry for rest of tonight much of the daytime on
Monday, though some model data hints at some elevated shower and
storm potential Monday afternoon across SE OK and NW AR, so will
keep a low Pop in those areas. Focus turns to storms that develop
along the dryline to west later Monday afternoon in conjunction
with an upper trough that lifts from the mountain west region into
the high plains Monday afternoon and evening. Potential for some
significant severe weather will exist with storms that northeast
Oklahoma late in the afternoon or more likely Monday evening.
Greatest coverage/higher end severe potential continues to favor
NE OK and NW AR Monday eve/night. Despite lower storm coverage
roughly from I-40 to the south, the environment will remain
supportive of a higher end severe threat with any storm that
develops. Coverage will diminish late Monday night and Tuesday
morning, leaving most much of the area in a lull. However, will
keep though low PoPs across the eastern sections of the forecast
area Tuesday and Tuesday night. An uptick in storm chances will
come Wednesday with a cold front that enters the area, with some
severe potential in place ahead of the front Wednesday afternoon
and evening. The boundary will push through the area by Thursday
morning. Cooler and drier air will filter into the area starting
Thursday. An upper trough in NW flow aloft will clip the area
Friday, and may produce a few showers across NE OK and NW AR,
however will leave PoPs out for now. Otherwise, settled conditions
are expected for the remainder of the forecast period.

&&

.AVIATION...
(12Z TAFS)
Issued at 623 AM CDT Sun May 5 2024

Widespread showers and storms currently across much of E OK will
steadily expand eastward through the day. Widely varying ceilings
having been noted both within the precip and further east across
NW AR. These varying flight levels are likely to persist however
the overall trend should be for low MVFR to IFR ceilings through
much of the day. Precip will end from west to east during the
afternoon, however ceilings will be slower to lift and lower
flight levels are forecast to continue into the overnight hours.

DISCUSSION...
Widespread showers and thunderstorms will continue spread over the

instability is slightly more favorable. Locally heavy rainfall
with the stronger storms will increase the threat for both flash

EXTENDED DISCUSSION...
The active weather pattern will continue this week with chances
for storms through Wednesday night. The higher severe weather
chances will come Monday with storms that develop to the west
along a dryline, and again Wednesday along a cold front. For
Monday, all modes of severe, including tornadoes will be possible
along with the potential for some significant severe weather late
Monday afternoon and into Monday night.

Storms that develop along a cold front Wednesday will also have
severe potential Wednesday afternoon and evening. Storm chances
are expected to diminish later in the work week as drier and
cooler air filters in behind the departing cold front.
