Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1248 AM CDT Sat Aug 30 2025

Valid 311200Z - 011200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
A couple of strong storms cannot be ruled out in the southern Plains
tomorrow (Sunday).

...Synopsis...
A mid-level trough will eject into the Atlantic while an upper ridge
builds over the Interior West tomorrow (Sunday). A northwesterly
mid-level flow regime will become established across the central
U.S., atop surface lee troughing, which will encourage continued
low-level moisture advection across the Plains. A mid-level impulse
will traverse the central Plains during the day, serving as a
lifting source, in addition to afternoon heating, to support at
least scattered thunderstorm development across the central and
southern Plains. 5.5-6.6 C/km mid-level lapse rates will support
meager instability amid modest vertical wind shear. The stronger
storms across the central and southern Plains may be accompanied by
a sub-severe wind/hail threat, with the chances of severe appearing
too low to warrant the addition of probabilities this outlook.
