Severe Thunderstorm Warning 512, NWS Norman, OK

Area Forecast Discussion
National Weather Service Norman OK
341 PM CDT Sat Aug 11 2018

.DISCUSSION...
The current batch of thunderstorms is expected to persist until
about sunset, then become much more isolated through the evening.
Then, as the weak cutoff upper low (currently located over New
Mexico) starts to drift east/northeast tonight, rain chances will
rise again after midnight. This low will move slowly east and
northeast into early next week, helping drag more deep moisture
north into Oklahoma and north Texas...and resulting in the highest
rain chances of the forecast period.

The low will move away on Wednesday, with drier air moving in
behind it. After a brief respite from high rain chances, another
upper low will drop into the Midwest from the northwest. Weak
troughs circulating around this low will again bring chances for
rain.

With increased vertical wind shear and greater instability, there
is some indication of a higher risk of severe storms in our
southeast counties Monday and Tuesday afternoons and evenings.
Otherwise, any severe weather should be brief and isolated,
generally in the form of wind gusts.

Because of the expected precipitation, afternoon temperatures
should be mainly below the seasonal average.
