Severe thunderstorms will be possible Monday evening ahead of and along a cold front across northwestern and northern Oklahoma. Storms may develop into a complex overnight, moving into central Oklahoma and the Oklahoma City metro area after 10 p.m.
The mostly likely timeframe for severe thunderstorms will be between 5 p.m. and 11 p.m.
Primary weather hazards will include hail up to the size of golf balls, and damaging thunderstorm wind gusts in upwards of 65 mph. The tornado potential is low, but not zero. Any storms forming ahead of the cold front could develop into supercell thunderstorms given the forecast, atmospheric conditions that are favorable for rotating updrafts.
Temperatures will quickly plummet behind the cold front with 30s expected across much of the area by Tuesday morning. A freeze is likely across extreme northwestern Oklahoma. North winds of 25-35 mph with higher gusts will result in wind chill values in the 10s and 20s for much of Tuesday morning.
A light mix of rain/sleet/snow will even be possible for a brief period of time early Tuesday morning across northwestern Oklahoma. Significant accumulations of ice or snow is not expected.
