Area Forecast Discussion
National Weather Service Norman OK
1245 PM CDT Sun May 30 2021

...New UPDATE, AVIATION...

.UPDATE...
Issued at 1245 PM CDT Sun May 30 2021

With a lot of lingering clouds, temperatures have remained cool,
especially in northern Oklahoma. The forecast was updated late
this morning to lower max temperatures a little bit.

&&

.SHORT TERM...
(Today and tonight)
Issued at 318 AM CDT Sun May 30 2021

Showers and storms over southwest Kansas and the Panhandles making
very slow progress eastward this morning, and will struggle to have
much impact on the body of Oklahoma before noon. What activity does
make it into Oklahoma will be mainly in the form of showers and not
thunderstorms. In fact, with mid-level shortwave ridge over the
region, it is shaping up to be a dry day for a majority of the
forecast area. Redevelopment late today into this evening still
expected near residual outflow boundaries on higher terrain to our
west. As upper trough moves closer and we get at weak steering
flow over Oklahoma and western north Texas, this activity should
move into the body of Oklahoma and western north Texas tonight and
Monday. Some heavy rain appears likely across western Oklahoma and
adjacent parts of northern Texas, but the impact areas have seen
little in the way of rainfall the past week or more.

&&

.LONG TERM...
(Monday through Saturday)
Issued at 318 AM CDT Sun May 30 2021

Upper low moving into Arizona fairly impressive in water vapor
imagery early this morning, more than models depict. Speed max
approaching Baja region will also allow amplification of trough
Monday and Tuesday, with model trends of cutting off this latter
energy influx, which will play into potential rain chances
continuing into next weekend. Northern portion of trough
progresses slowly into the Plains with lower level upslope flow
continuing, resulting in continued daily convective initiation on
the higher terrain to our west least through Tuesday when the
trough phases with northern stream s/wv moving through northern
Plains. Heavy rain will be a concern mainly late Monday through
late Tuesday, especially across central and southern portions of
Oklahoma into western north Texas. Given antecedent soil
conditions we have contemplated a Flood Watch, but with some model
disagreement in latitude of heavier rainfall accumulations, we
will keep heavy rain wording in grids and graphics, but hold off
on issuance of a watch this morning since we are still in the 48
hour range out for this particular threat.

Much less in the way of convective coverage expected from Wednesday
through Friday, before the previously mentioned cutoff energy gets
kicked eastward over the Southern Plains. While there are timing
differences in the medium range models, they do depict scenario of
this energy getting kicked north and east over the region late next
weekend into the following week as a progressive s/wv trough breaks
off strong westerlies to our north. Confidence is low on timing and
impacts with scenario, but it is possible our wet pattern will
continue into next week.

&&

.AVIATION...
(18Z TAFS)
Issued at 1245 PM CDT Sun May 30 2021

Areas of MVFR ceilings persist this afternoon across southwest
Oklahoma/western north Texas as well as north central Oklahoma.
There will be some variability in where these lower ceilings are,
but expect areas of MVFR ceilings to persist. One wave of showers
is near the OK/KS line moving east with another wave in the
eastern Oklahoma panhandle moving into northwestern Oklahoma.
Additional showers and thunderstorms are expected to develop in
eastern New Mexico and west Texas this afternoon and evening and
move into Oklahoma/north Texas overnight.

1235 PM CDT Sun May 30 2021

This hazardous weather outlook is for portions of northern...
western...central...and southern Oklahoma...and western north
Texas.

.DAY ONE...Through tonight...

.Thunderstorms...
Thunderstorms are expected to develop over the Oklahoma and Texas
Panhandles this afternoon, then move into western Oklahoma and
western north Texas during the evening and overnight. A few strong
to severe storms are possible across far western Oklahoma and
adjacent parts of north Texas. Damaging wind gusts will be the
main threat.

.Heavy Rain...
Rain totals of one to three inches will be possible across western
Oklahoma and adjacent parts of northern Texas. While this may
cause some localized flooding of low-lying and poor drainage
areas, widespread flooding appears unlikely.

.DAYS TWO THROUGH SEVEN...Monday through Saturday...

.Thunderstorms...
Widespread thunderstorms are forecast to spread across much of
Oklahoma and northern Texas Monday into early Tuesday. While a
few strong storms will be possible, organized severe weather
appears unlikely. Although not as widespread, thunderstorm chances
will continue Wednesday into Saturday, mainly across southern
Oklahoma and northern Texas.

.Heavy Rain...
Repeated rounds of showers and thunderstorms may result in high
rain totals and flooding problems over areas that have seen
several inches of rain the past week.
