Severe Thunderstorm Watches Issued as Storms Bring Risk of Damaging Winds and Flash Flooding

Overview

• The NWS Storm Prediction Center issued Severe Thunderstorm Watch 670 and Watch 671 on Saturday covering parts of central and northeast Kansas, western into north‑central Oklahoma, the eastern Texas Panhandle, and eastern Colorado into northwest Kansas.
• Watches warn of scattered damaging wind gusts as high as 75 mph and isolated large hail up to 2 inches with multicell and line segments producing the main severe threat.
• The Weather Prediction Center highlighted a developing mesoscale convective system over northeastern Kansas that could produce widespread heavy rain with 2–4 inch swaths and pockets of flash flooding into the early overnight hours.
• Meteorologists point to a slow‑moving closed upper‑level low, anomalously high low‑level moisture, steep low‑level lapse rates, and pockets of strong CAPE and DCAPE that favor slow, backbuilding storms that concentrate wind, hail, and rainfall.
• Local NWS offices warn of overnight flash‑flood warnings and possible downstream watch extensions and advise residents in flood‑prone or saturated areas to monitor radar, follow warnings, and avoid flooded roads.
