It relates to something called a cap, a layer of stable air that often forms a little more than a mile above the ground. This layer of air can prevent thunderstorms from rising up.
The cap is something of a double-edged sword for severe thunderstorms. In many severe weather outbreaks, the cap plays a crucial role in that it initially holds back storm formation, allowing the air below it to become highly unstable. When the cap weakens, the storms punch through and become very powerful due to the instability below.
However, in other instances the cap holds and the storms fail to develop.
So, busted high-risk days are often the result of meteorologists wrongly predicting that the storms will be able to break the cap.

What are the four examples of severe weather?
For examples of severe weather are: tornadoes, earthquakes, hurricanes, and severe thunderstorms. High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, downbursts, lightning, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones. Regional and seasonal severe weather phenomena include blizzards, snowstorms, ice storms, and duststorms
Is there potential for another high risk of severe thunderstorms April 29th 2014?
It is too early to tell at this point. The SPC has not mentioned consideration of going to a high risk, and April 29 did not show up as strongly on the long-term forecast. Additionally, only once has the SPC ever issued high-risk outlooks for three days in a row.
Is there potential for a high risk of severe thunderstorms on May 9 Th 2015?
It is possible that a high-risk outlook will be issued. The SPC has issued a moderate-risk area on that date in their day 3 outlook, which is unusual.
Do high altocumulus clouds cause thunderstorms?
No. Altocumulus do not cause thunderstorms, but altocumulus castellanus can be a sign that thunderstorms will develop later in the day.
Which are characteristics of a high pressure area?
cool dry air :D

What is a Small intense weather system that produces strong winds?
A thunderstorm, most likely a severe thunderstorm.
Is there potential for a high risk of severe thunderstorms on May 8 Th 2015?
It is unlikely unless the area under the moderate-risk outlook is expanded.
Calm area of a cyclone?
The calm area of a tropical cyclone is the eye. The circular eye of the storm is surrounded by a high wall of thunderstorms where the most severe weather occurs.

Can there ever be a Day three high risk for severe thunderstorms?
In all likelihood, no. There have only ever been two day 2 high risk outlooks. Issuing a high risk outlook means that the SPC is predicting with a high degree of certainty that there will be a major severe weather outbreak. A day 3 outlook cannot be issued with such certainty.

Is it true that a severe storm warning means that severe thunderstorms have formed and people should get inside?
True Probably recommended to get inside because what comes along with severe thunder storms...sometimes tornadoes and high winds or damaging hail.
What Tornado and thunderstorms have in common?
they both have high winds and both have high damages.
Is there potential for a high risk of severe thunderstorms on may 11th 2014?
It is not likely. Currently the moderate-risk outlook has been issued for hail, for which the SPC does not issue high-risk outlooks. Only slight-risk outlooks have been issued for wind and tornadoes.
