Low pressure weather is when the atmosphere is relatively thin.

Usually low pressure weather means unsettled weather.

A low pressure system has lower pressure at its center than the areas around it.

Winds blow towards the low pressure, and the air rises in the atmosphere where they meet.

A high pressure system has higher pressure at its center than the areas around it.

Winds blow away from high pressure.

Low Pressure weather Typically Equals Unsettled Weather.

Locations in front of a low center (out ahead of the warm front) typically see cool temperatures and steady precipitation.

Locations to the south and east of a low center (a region known as the "warm sector") will see warm, moist weather.

In weather low pressure areas are places where the atmosphere is relatively thin.

Winds blow inward toward these areas. This causes air to rise, producing clouds and condensation.

Low pressure areas tend to be well organized storms.

Atmospheric pressure is an indicator of weather.

When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation.

High-pressure systems usually lead to fair, calm weather.
