Key Messages
- Warm, dry, and gusty conditions this afternoon will be monitored for any fire weather concerns. Conditions are also just short of Lake Wind Advisory and this will be monitored for as well.
- The first major frost of the season is possible along river bottoms Thursday morning, due to cooler surface temperatures associated behind a cold front.
- There is a small chance for isolated shower or thunderstorm Friday afternoon and evening. Totals do not look significant.
