Oklahoma MCV Boundary Setup Eyes 80 MPH Wind Clusters — SevereWX

An approaching mid-level cyclone (MCV) over northwest Oklahoma is colliding with a quasi-stationary boundary near the Oklahoma-Kansas line, setting the stage for scattered storm development this afternoon.

Strong daytime heating is building cumulus fields in a plume of steep low-level lapse rates, especially along the boundary and upstream in west-central Oklahoma. Surface dewpoints in the mid-60s°F and MLCAPE nearing 2000 J/kg are creating a moist, unstable environment ripe for thunderstorms after 4 PM CDT (21Z).

Weak wind shear means storms will move slowly with a pronounced southward push due to veering winds aloft. High precipitable water values boost the risk of heavy rain and outflow winds, with the strongest clusters capable of gusts from 65-80 mph—potentially over 70 mph locally. Stronger updrafts may briefly produce hail up to 1.25 inches.

The Storm Prediction Center highlights this in Mesoscale Discussion 1588, valid until around 9:30 PM CDT, with a 60% chance of a severe thunderstorm watch. Northern into central Oklahoma bears the brunt.

Stay prepared: Secure loose outdoor items, monitor local radar and warnings via NOAA Weather Radio or apps, and seek shelter indoors away from windows if storms approach. Have a severe weather plan ready.
