SIGNS OF A STORM COMING

1. A drop in temperature. Pay close attention to the temperature levels outside.
2. Large, billowy clouds. Large, billowy clouds that continue to grow as the day heats up are known as cumulus clouds.

4. Darkening of the clouds.
5. A weather program predicts it.

Why do storms happen?

The air cools as it rises. Water vapor condenses and forms cumulus clouds. When condensation occurs, heat (latent heat/energy ) is released and helps the thunderstorm grow. At some point, condensation high in the cloud (now in the form of water droplets and ice) falls to the ground as rain.

What happens before a storm?

As the warm, moist air is pulled into a storm system, it leaves a low-pressure vacuum in its wake. The air travels up through the storm cloud and helps to fuel it. Warm, dry air is relatively stable, and once it blankets a region, it stabilizes that air in turn. This causes the calm before a storm.

What are the 4 types of severe weather?

High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones. Regional and seasonal severe weather phenomena include blizzards (snowstorms), ice storms, and duststorms.

Are there any severe thunderstorm warnings?
