Area Forecast Discussion
National Weather Service Norman OK
314 AM CDT Mon Jun 7 2021

...New LONG TERM...

.SHORT TERM...
(Today and tonight)
Issued at 126 AM CDT Mon Jun 7 2021

Challenging forecast in the short term for precipitation chances
given the disagreement among CAMS and synoptic models. The
midlevel low currently centered near KS/MO/OK/AR border slowly
lifts northeastward as a few shortwaves rotate around the center
of the upper low. Periods of showers/thunderstorms are expected
through tonight, though there is quite a bit of uncertainty as to
timing and location as models struggle with precip development.
Regardless, scattered storms are likely this morning, generally
south of I-40. Locally heavy rainfall is a concern with a slight
risk of flooding for southern Oklahoma and western north Texas.

.LONG TERM...
(Tuesday through Sunday)
Issued at 314 AM CDT Mon Jun 7 2021

Will have some lingering POPs east on Tuesday, then the upper
trough will move east and the upper ridge will begin to build into
the area. NAM and GFS both start pushing some very warm low-level
air into the western and southern part of the area mid week as
seen by the warm progged 850 mb temperatures, but it may be
difficult to get surface temperatures quite as warm as these 850
mb temperatures would support given recent rainfall and high
high dewpoints expected to remain over the area.

A northern stream wave moves toward the northern Plains which will
both act to flatten the upper ridge somewhat, but also nudge a
front down the Plains into the area Thursday night or Friday.
Beyond that, there are hints of a weakness around the east side of
the ridge that could bring some precipitation to eastern sections
of the area this weekend, but confidence is not high trying to
key in on such a relatively subtle feature that far into the
future.

&&

.AVIATION...
(06Z TAFS)
Issued at 1056 PM CDT Sun Jun 6 2021

Still expecting showers and thunderstorms to develop over central
OK, and move into southwestern OK and north TX overnight. However,
coverage still appears questionable so have adjusted a few of the
TAFs to exclude any mention of CB/TS. MVFR to IFR cigs, and
perhaps some BR, will also remain in the forecast for early Monday
morning. Flight conditions should improve rather quickly after
14-15Z. Additional shower and thunderstorm chances may continue
after 15Z near PNC and SWO.
