Forecast
The barometric pressure in Longmont, Colorado, changes constantly. It is affected by weather systems moving into the area. These systems can bring high or low pressure.
Longmont is situated in a valley near the Rocky Mountains. The mountains to the west influence the weather in the city. Moist air from the west moves into the valley.
This air is pushed upwards by the mountains, causing it to cool and condense. This process leads to precipitation in the form of rain or snow. The surrounding terrain also creates channels for winds to move through.
