Evening Thoughts...

* We still think there is a significant threat of severe weather Saturday night and into Sunday morning..Let's summarize the threat:

When: 6pm Sat-6am Sun (Although we could see thunderstorms earlier on Saturday PM)

Where: All of our area

Most Significant Threat: Damaging Winds and Isolated Tornadoes

Main Limiting Factor: Lack of instability. Surface based instability is forecast to be between 200-500 J/kg; for tornadoes, we usually see values closer to 500-1000. This will be the key factor in determining the magnitude of this event.

* Outside of any thunderstorm activity, winds Saturday and Saturday night will gust up to 35 mph, so you might want to secure any loose items around your home (garbage cans, grill covers, etc.). If you have plans to be on area lakes on Saturday, be aware that the wind will be quite strong.
