Thunderstorm downdrafts are cold because the air has been cooled by rain. The cooled air then sinks as it has become denser than the surrounding air.

What part During the life cycle of a thunderstorm which stage is characterized predominately by downdrafts?
Dissipating.
Why are there often updrafts and downdrafts in supercells?
All thunderstorms contain updrafts and downdrafts, and in fact no thunderstorm could exist without updrafts. A thunderstorm forms when it a mass moist of air is lifted to a point where it is warmer than its surroundings and so rises on its own. This is the updraft and is the storm's source of power. As a storm matures, rain cools the air within it, causing it to sink and form downdrafts.
Does an intense thunderstorm has a relatively cold or warm cloud top?
cold
What is caused by heavy snowfall combined with strong updrafts and downdrafts?
whiteout
Are there any fronts in a thunderstorm?
Fronts do not occur in a thunderstorm, but they are a common cause of them. In the middle latitudes, one of the most common places to find a thunderstorm is at or just in front of a cold front. However, thunderstorms do not require a front in order to form. Many thunderstorms will produce something called a gust front, which occurs as rain-cooled air moves out the front of the storm. This is technically not a front, but it does have some similarities to a cold front.
The stage in a thunderstorm's development in which the updrafts roughly equal the downdrafts is the?
mature stage

What are down drafts?
Downdrafts are damaging winds on or near the ground. They are called downbursts or microbursts if caused by a thunderstorm which they usually are
Is it true that hurricanes are classified by three stages in which updrafts of air billow up updrafts and downdrafts swirl the wind up and down then downdrafts cause clouds to come apart?
No. These stages define the life cycle of a thunderstorm, not a hurricane.
Why is a cold front thunderstorm usually more severe than a warm front thunderstorm?
A cold front is more severe because it is steeper.
What are two characteristics of a thunderstorm that lead to hail formation?
First water droplets exist in the liquid state in the parts cumulonimbus cloud.second is strong updrafts and downdrafts exist side by side with in a cloud
Does an intense thunderstorm has a relatively cold or warm cloud top?
cold
Why does weather usually become cool and clear after a severe thunderstorm?
Weather becomes cool and clear after a thunderstorm because of the instability in the air along the "frontal boundary" between warm air and cooler air pushing in behind it. The reason it usually becomes cool after a thunderstorm is because after the storms have settled, the jet stream has pushed the warmer air further east and the cooler air has moved in its place. Thunderstorms contain updrafts and downdrafts. The downdrafts (caused by falling precipitation) drag cold air down from the top of the storm. When this air hits the ground it spreads out in all directions. The air from this downdraft moving in the direction of the storm is called a "gust front" and arrives just ahead of it and brings a nice cool breeze on a hot day.
Why do you see lighting before it rains?
Research on lightning frequency and rainfall suggests that the action of hydrometeors (rain and hail) being carried around in the thunderstorm (in updrafts as well as downdrafts) creates electrical charge buildup in the clouds.
which is not part of the recipe for a thunderstorm to form?
A cold front advancing
What is the temperature for a thunderstorm?
Prior to a Thunderstorm, the temperature can range anywhere from 60 to 90 degrees F but the humidity and dewpoint will be very high. As the Thunderstorm releases rain, the temperature will decrease. It brings cold air down from the top of the Thunderstorm.
