A dynamic storm system is moving across the southern and central Plains on Monday, bringing multiple waves of thunderstorms, the risk of strong tornadoes, and damaging wind gusts to Oklahoma and Kansas.

Forecasters are warning residents to prepare for severe conditions that could stretch from the early morning hours well into the evening, with atmospheric conditions capable of producing significant wind damage and large hail across both states.

Tornadoes and high winds expected in Oklahoma

In Oklahoma, meteorologists anticipate as many as three separate rounds of storms throughout the day, according to KOKH. The first wave developed overnight in western Oklahoma between 1 a.m. and 6 a.m., moving in from the panhandles with the potential to generate 70 mph wind gusts and brief spin-ups before diminishing ahead of the morning commute.

A more widespread severe threat is expected to develop during the afternoon and evening hours. The Storm Prediction Center placed almost the entire state, excluding the Oklahoma Panhandle, under a slight risk of severe weather, KOKH reported. Atmospheric conditions will support all severe hazards, including wind gusts reaching 75 mph, hail as large as golf balls, and tornadoes.

Forecasters note that an advancing trough could trigger storms between noon and 2 p.m. along and east of Interstate 35. However, the most potent risk is projected along a dryline in western Oklahoma later in the afternoon. Storms developing from the Kansas border down to North Texas carry a 5 percent tornado risk outlined by the Storm Prediction Center, with the potential for strong tornadoes reaching EF-2 intensity if sufficient clearing and daytime heating occur.

Rounds of hail and rain across Kansas

Farther north, Kansas faces its own series of severe weather rounds beginning early Monday, KWCH reported. Activity that began overnight in western Kansas was projected to track into central parts of the state near daybreak.

While scattered storms will push east throughout the morning, a second round is forecast to erupt during the late afternoon and evening across central and eastern Kansas. KWCH reported that some of these late-day storms could turn severe, carrying isolated hail and strong wind gusts before pushing toward the eastern state line late Monday night.

Rainfall totals across Kansas are expected to be heaviest in central and eastern counties, where a half inch to one inch of precipitation is forecast. Western Kansas will generally receive less than a half inch. A few lingering showers may persist across northern Kansas through Tuesday morning.

Safety measures and weekly outlook

Emergency guidance emphasizes that severe thunderstorm warnings indicate verified, active hazards, which officially trigger when winds reach at least 58 mph or produce hail measuring one inch in diameter or larger, according to Istituto Impariamo. Safety experts advise people in warning zones to avoid remaining in mobile homes or parked vehicles and instead seek shelter inside sturdy structures away from exterior windows.

Behind the advancing storm boundary, a cold front will usher in noticeably cooler air across the Plains. According to KWCH, Kansas will see daytime temperatures drop into the 60s on Tuesday, setting up a stretch of mild, cooler autumn conditions that will linger through the remainder of the week.
