A few severe storms are possible in the Mid-Mississippi Valley Thursday from eastern Illinois and southern Indiana through parts of the Ozarks.
A Marginal Risk (level 1 out of 5) is in place for isolated strong to severe storms.
This comes as a jet stream level low swings through the region and provides the lift and wind shear needed for thunderstorm development.
The upper low combines with limited energy along a cold front. While surface energy is on the lower side, there’s enough energy due to returning moisture from the Gulf of Mexico and lift along the cold front to generate a few isolated to scattered severe storms.
Gusty winds of 60 mph or higher is the greatest threat through the risk area Thursday.
Forecast
A few showers and thunderstorms will form near the front by mid-morning Thursday as temperatures rise and the upper low approaches.
By early afternoon a cluster of thunderstorms in southeast Missouri, Illinois and Indiana is likely to form. Storms could have heavy rain, gusty winds and small hail.
As energy increases along the cold front in the afternoon and the upper low passes overhead, thunderstorm coverage and intensity will increase. A line of storms with gusty winds and hail is expected from western Ohio through the Mid-South.
The line of storms will move through quickly in the late afternoon and evening. By late Thursday evening into the overnight hours, energy will be lessening and thunderstorm strength will decrease as well.
Paducah, Kentucky is one of the spots included in the Marginal Risk Thursday. Once this system clears out, an active pattern builds in to start the weekend with rain and thunderstorms in the forecast through mid-week next week.
