Area Forecast Discussion
National Weather Service Norman OK
552 AM CDT Wed May 17 2017

.DISCUSSION...
The 12Z aviation discussion follows....

&&

.AVIATION...
A tight pressure gradient across Oklahoma and north Texas will
result in a windy morning, followed by a gradual decrease in wind
speeds through the afternoon. Winds will drop off more quickly
toward sunset, with most sites averaging about 10 kt overnight.
As low-level moisture returns from the southeast tomorrow
morning, some stratus will be possible. It is unclear at this time
how much there will be (geographical coverage) and how long it
will last. Confidence in the cloud layer is high enough to mention
it in the TAFs for KOKC and KOUN, but not for other sites. It is
very unlikely that this cloud layer will reach KGAG or KWWR.

.PREV DISCUSSION... /issued 258 AM CDT Wed May 17 2017/

DISCUSSION...
The current area of rain/thunderstorms will move east early this
morning, and should be east of our forecast area by about 7 am,
leading to a breezy, but dry day.

On Thursday, low-level moisture will surge back northwest across
our forecast area, setting the stage for another round of severe
thunderstorms. COnditions Thursday afternoon and evening
generally resemble those of this past afternoon/evening, although
with a somewhat more northerly area of the greatest chance of
severe storms.

A cold front will arrive Friday, and there will be yet another
risk of severe storms, mainly along and south of this front. It
appears that the risk will be mainly near/southeast of I-44. As
this system moves slowly southeast, heavy rain will be likely from
southwest Oklahoma to central Oklahoma. Amounts may not be
sufficient for widespread flooding, but some localized flooding
is likely.

Rain finally comes to an end on Sunday, but another wave coming
south across the Plains will bring rain/thunderstorm chances back
into the forecast Monday and Tuesday. With that system, the risk
of severe storms will be substantially lower than those of this
week.
