Ethylene glycol can be diluted in a solution of 50 per cent water and 50 per cent coolant (or antifreeze!) to lower the freezing temperature of the fluid in your radiator by 60 genres or more. That's cold. But coolant isn't finished amazing you yet.
A severe thunderstorm warning, on the other hand, is not issued until such a storm has been physically observed or is spotted on radar. A tornado watch is issued when conditions may produce a tornado, and a warning is issued when a tornado has been sighted, or when rotation is seen on radar.

A Severe Thunderstorm WATCH is issued by the NOAA Storm Prediction Center meteorologists who are watching the weather 24/7 across the entire U.S. for weather conditions that are favorable for severe thunderstorms.
