Key Messages
- Scattered rain possible today, mainly west of I-69.
- There is a Marginal Risk of severe storms (mainly wind) along and south of US Route 24 this evening. Confidence in severe weather is low.
- Turning much cooler and windy for Friday with some lake effect rain showers expected. Watching for frost chances, which appear the most possible Sunday morning, but Saturday morning`s chances cannot be ruled out.
