USING CLIMATOLOGY TO FORECAST THUNDERSTORMS IN SOUTHEAST COLORADO Stan Rose, Meteorologist, National Weather Service, Pueblo, CO

Microburst Winds

Damaging Winds Thunderstorms can produce strong damaging wind gusts up to 100 mph. Cold dense rain cooled air accelerates down from the thunderstorm base and spreads outward along the ground creating strong outflow winds.

Aircraft Induced Lightning

Thunderstorms Ingredients for a Thunderstorm – Moisture – Instability – Lift Sun warms the ground and the air begins to rise (convection) Clouds form and build into thunderstorms as moisture condenses within the rising bubbles of air
