Winter Storm Potential (as of 1/24/23)

A major winter storm will be moving into our area late tonight and will last into Wednesday morning. We’re on the very southeastern edge of this storm, so all of the warnings and advisories end directly over the middle of the KBSI viewing area.

Those in the Winter Storm Warning have the best chance for accumulating snow. Those in the Winter Weather Advisory have the best chance for minor accumulations with some rain mixing in. Then those south and east of the winter headlines will see mostly rain with a little snow every now and then. The cutoff of snow vs no snow will be sharp!

Winter Weather Advisories (purple) and Winter Storm Warnings (pink) are in place from 6:00pm this evening through noon Wednesday.
