After several dry and warm days, it looks like the chance for rain and thunderstorms will return with the arrival of a cold front late Wednesday night, a few of which could be on the stronger side. Conditions will remain dry - outside of a small chance for an isolated shower late morning Wednesday - as temperatures warm back near 80 degrees. Southwest winds will be gusty, nearing 40-45 mph throughout the afternoon.
A cold front moving in from the west will bring the highest threat for severe thunderstorms across parts of the Plains and Mississippi River Valley during the afternoon and early evening. It's in these areas where instability and forcing will be the highest. As the front nears the Mississippi River Wednesday evening it'll be moving into an environment with a little less instability, however, winds aloft will be increasing.
This may work to keep at least a small risk for a strong to severe wind gust with any of the storms that move through after 9pm locally Wednesday night. That threat will decrease the further east the front moves through Thursday morning.
A 'marginal risk' for severe weather is currently in place for areas along and west of I-39 through Wednesday night. While the threat is low, it is still best to make sure you stay weather aware as these late season, fall storm systems can give us some surprises.
