245 ACUS02 KWNS 220522 SWODY2 SPC AC 220520 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1220 AM CDT Wed Jul 22 2026 Valid 231200Z - 241200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorm potential appears low on Thursday. However, locally gusty winds could occur with thunderstorms across the central High Plains. ...Discussion... In the mean, an amplified upper ridge will persist across he West, with the subtropical high over TX shifting west toward the Four Corners vicinity through the period. An upper shortwave trough embedded within the eastern periphery of the upper ridge will migrate southeast from the central Rockies to the Mid/Lower MO Valley through early Friday morning. Southerly low-level flow across the Plains will result in a belt of modest boundary-layer moisture across the central High Plains. Steep midlevel lapse rates will foster weak instability across parts of WY/CO into western KS. Scattered thunderstorms will develop during the afternoon and spread east/southeast across the central High Plains. A deeply mixed boundary layer will support isolated strong outflow gusts. However, weak vertical shear and limited instability will preclude severe probabilities at this time. ..Leitman.. 07/22/2026 $$
