Oklahoma Faces 80 MPH Gusts; Mid-South Storms Follow Suit
Afternoon thunderstorms are gearing up to pack a punch across a broad swath from northern and central Oklahoma southeastward into northern Arkansas, western Tennessee, and northern Mississippi. The Storm Prediction Center (SPC) has issued two Mesoscale Discussions (MDs) highlighting this threat, with watches possible at 60% odds in both regions.
In northern and central Oklahoma, an old mesoscale convective vortex (MCV) from earlier storms is drifting southeast, paired with a stalled boundary near the Oklahoma-Kansas line. Intense heating is building towering cumulus clouds in a moist, unstable atmosphere boasting nearly 2,000 J/kg of MLCAPE and mid-60s dewpoints. Expect scattered storms to fire up after 4 PM CDT, moving slowly south with potential for gusts up to 80 mph and brief quarter-sized hail from the strongest cells.
Further east, a weakening shortwave trough over Missouri nudges stronger winds aloft into northern Arkansas and nearby areas. A key boundary hugs the Missouri-Arkansas line into western Kentucky, fueling convergence and steep low-level lapse rates amid peak heating. Storms should spark along this line post-2 PM CDT, spreading east-southeast with 55-70 mph wind gusts possible in clusters, plus isolated marginal hail.
What does a Mesoscale Discussion mean for you? SPC uses MDs to flag fast-evolving severe weather risks on smaller scales where conditions could quickly warrant a watch. Think of it as an early heads-up: stay tuned to radar and local alerts, as a tornado or severe thunderstorm watch could drop soon.
Both areas share similar setups—boundaries, heating, and ample moisture driving pulse storms with wind as the main foe. Peak timing aligns with max instability this evening.
Stay prepared: Charge your phone, secure outdoor items, and have a safe spot ready for sudden severe weather. Monitor NOAA Weather Radio or apps like SevereWX.net for updates. Safety first as these storms rumble through!
