942 ACUS02 KWNS 300550 SWODY2 SPC AC 300548 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. ..Squitieri.. 08/30/2025 $$
