This is the THUNDERSTORM outlook not the SEVERE thunderstorm outlook.

We're on the southern periphery of a moderately strong jet stream with the greatest dynamics from the more powerful,  ZONAL jet streak in the center pretty far north of us. 

This was the last severe weather outlook from the Storm Prediction Center.

I was sort of ignoring it, sorry about that. The main risk is for large hail, then a severe thunderstorm wind with the chance of a tornado not being 0 but being below 2%. 

https://www.spc.noaa.gov/products/outlook/day1otlk.html

1. All categories

2. Risk of tornadoes-less than 2%

3. Risk of a wind gust of 58 mph+

4. Risk of large hail within 25 miles of any 1 point. Hatched area represents LARGE hail. 

Again, the life threatening risk for this event is VERY low. What do you do when large hail is falling or winds are gusting above 58 mph during a warning for those elements?

Stay inside and away from windows. 

What about in a car?

1. Try to avoid driving in an area surrounded by tall trees or objects/power lines that can be blown on to the road during the storm. 

2. Lightning: A typical cloud-to-ground, actually cloud-to-vehicle, lightning strike will either strike the antenna of the vehicle or along the roofline. The lightning will then pass through the vehicle's outer metal shell, then through the tires to the ground. It can so tremendous damage to some of the components but YOU ARE SAFE.

Lightning is present in ALL thunderstorms, not just severe thunderstorms.

This is extremely unusual.

The cold front went thru Evansville almost an hour ago. Normally, that's the lifting agent that triggers the storms.

However, that much colder air hugging the ground has raced south really fast and there is still warmer air above the surface being lifted and causing storms WELL BEHIND the front.

This is our local weather service in Evansville.

The cold front is well south of the Ohio River at 9pm with scattered strong storms still 30 minutes north!

The temperature dropped 25 Deg. F in just 1 hour between 8-9pm. From 80 to 55!
