High pressure usually results in fair weather; sunny days, few clouds. If the high is strong enough, storm systems will actually swirl around the outside of a high pressure "dome." Highs are created when the air within them sinks, subsequently putting "pressure" on the atmosphere.
Low pressure usually results in unsettled weather, including rain and storms, because the air is not being oppressed as in a high pressure ridge, so it has the opportunity to rise and create instability.

High pressure is an area of a clockwise flow of sinking air that creates cooler temps and mild weather because storms can't develop under the amount of pressure pushing down on them.
Low pressure is an area of a counterclockwise flow that means southerly winds and warmer temps. This creates more storms because there is more moistre on the southerly winds and also more lift that the storms need to develop.

Exactly that. Look at a barometer when you are in a low pressure area and it will be below 30 and when you're in a high pressure area it will be above 30.00

A high pressure cap results in nice days, but if it stays too long, it can result in a severe drought.
Low pressure systems can result in rain storms, and sometimes winter weather.
