Damaging Winds Surge from NE Oklahoma into N Arkansas — SevereWX
Damaging Winds Surge from NE Oklahoma into N Arkansas
Scattered thunderstorms are firing along a cold front, bringing a serious risk of damaging wind gusts through the evening in portions of northeastern Oklahoma, southeastern Kansas, southern Missouri, and northern Arkansas.
The Storm Prediction Center highlights moderate to strong instability—up to 3500 J/kg MLCAPE in NE Oklahoma—combined with dewpoints in the mid-70s°F and plump PWATs over 1.75 inches. This setup favors water-loaded downdrafts capable of 55-70 mph gusts. While effective shear is marginal at 20-30 knots, loosely organized clusters or even marginal supercells could form, boosting the odds for isolated large hail (1-1.75 inches) in stronger updrafts, particularly westward into Oklahoma.
A brief tornado can't be ruled out either, with surface vorticity along the front and remnant outflows overlapping robust low-level buoyancy. Peak probabilities point to EF1-intensity twisters (up to 90 mph), but the main story remains those potentially disruptive winds.
SPC's Mesoscale Discussion 1338 gives a 40% chance of a watch, valid until around 7:30 PM CDT. Activity is already picking up per satellite and lightning data, from SE Kansas into central Missouri.
Communities from Tulsa northward through Joplin, Springfield, Branson, and into Jonesboro—pay close attention. Radar trends will dictate if storms intensify.
Stay prepared: Monitor local NWS updates, have a severe weather plan, secure outdoor items, and seek shelter if rotation or intense lightning develops. Safety first as evening commutes heat up.
