What forecasters said that day

NWS Norman, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at May 24, 6:23 PM CDT, 1 hour 6 minutes earlier.

Area forecast discussion, May 24, 6:23 PM CDT, 1 hour 6 minutes before

Area Forecast Discussion
National Weather Service Norman OK
623 PM CDT Fri May 24 2019

.AVIATION...
A line of storms currently stretching from north central Oklahoma
down through far southwest Oklahoma is expected to continue into
the evening, gradually moving southeastward. Included tempos at
KLAW, KOKC, and KOUN, though there is still some uncertainty as to
whether or not storms will make it that far south (chances for
KSPS are too low for mention in TAF). MVFR to perhaps IFR ceilings
are expected to set in again in the morning before lifting a bit
tomorrow afternoon.

.PREV DISCUSSION... /issued 309 PM CDT Fri May 24 2019/

DISCUSSION...
Scattered showers and thunderstorms continue to form, mainly along
and north of a surface front. Part of the boundary has shifted
northward this morning where instability is increasing and
updrafts are more vigorous. As heating continues through the
afternoon, more numerous storms will develop, especially from west
central to north central Oklahoma. Although severe storms will be
possible, perhaps the greater risk will be heavy rainfall and
flash flooding. It is certainly possible that another 3 to 5
inches of rainfall could occur this afternoon into tonight. If
this happens across north central/central Oklahoma, life-
threatening flash flooding will be likely given antecedent
conditions.

There may be an overall decrease in convection late tonight into
Saturday morning as low level winds veer and decrease some.

Convective develop Saturday and Sunday should mainly be over
the higher terrain to our west which will impact parts of western
Oklahoma and northern Oklahoma during the evening and overnight
hours. Coverage may be greater on Sunday as models suggest a more
pronounced wave will approach the southern and central Plains.
Unfortunately, some of the storms over the weekend will produce
heavy rainfall amounts which will likely result in additional
flooding.

There may be a lull in storms on Monday, but another trough will
approach the area Tuesday into Wednesday. Severe storms and more
flooding will be a concern during this period.
