Area Forecast Discussion
National Weather Service Norman OK
241 AM CDT Tue Mar 24 2020

...New SHORT TERM, LONG TERM...

.SHORT TERM...
(Today and tonight)
Issued at 238 AM CDT Tue Mar 24 2020

At the time of this writing, thunderstorms are making their way
eastward across northern Oklahoma with the potential for heavy rain
and marginally severe hail. Expectation is for intensity to start
dwindling after 4am, and for storms to make their way east out of
the CWA around 7am.

Winds will shift to the north today and clouds will gradually clear
out, making for a fairly mild day as ridging starts to move in.

Day

&&

.LONG TERM...
(Wednesday through Monday)
Issued at 238 AM CDT Tue Mar 24 2020

Wednesday and Thursday will be dominated by modest upper level
riding and 850mb downslope flow. This will result in warm
temperatures and breezy winds, primarily across western Oklahoma on
Wednesday, but potentially more widespread on Thursday. One limiting
factor might be cirrus. Model blends show a potential for very high
clouds both days. Bumped temperatures toward MOS guidance on
Wednesday and winds toward MOS guidance both Wednesday and
Thursday.

An upper low will approach late on Thursday. Models show the
associated front stalling somewhere in Kansas to northern Oklahoma,
but model spread in location is still high. Depending on where this
sets up, we could see some precipitation in northern Oklahoma as
moisture returns overnight. As mentioned in the previous AFD,
capping appears strong, instability modest, and shear high (as a
strong low level jet moves over). If we get storms (PoPs are still
fairly low given all the uncertainty in timing/location), some of
them could be strong to severe.

High clouds are expected to move in Friday, limiting daytime
heating somewhat. The front will finally surge through Friday
night. With the upper wave moving in and the more pronounced
surface forcing, rain chances will be higher ahead of this surge
Friday evening and overnight, primarily over eastern Oklahoma
(where the best moisture will be). Strong capping, modest
instability, and strong shear will again make strong to severe
storms possible.

Behind this front, cooler temperatures along with drier weather can
be expected for the weekend. Models show another wave moving through
sometime early next week.

Day

&&

.AVIATION...
(06Z TAFS)
Issued at 113 AM CDT Tue Mar 24 2020

Primarily IFR/LIFR conditions expected at KWWR before rain moves in
and is expected to help alleviate the dense nature of the fog.
IFR/MVFR conditions elsewhere with lowering cigs and areas of fog
development. Chances for SHRA/TSRA will be highest across KWWR and
KPNC, with KPNC likely to see the most persistent impacts from TSRA
in the 09-12Z time frame. Low clouds primarily in the MVFR range may
persist into tomorrow afternoon across northern Oklahoma. Northerly
wind shift will spread over the region late tonight and tomorrow
with most winds becoming light by 00Z.
