Forecast

The barometric pressure in Idaho Falls is typically high. It averages 30.12 inches. This is because of the city's inland location.

The surrounding landscape is a factor in the pressure. Idaho Falls is situated in a valley. The Teton Mountains are to the east. The Snake River Plain is to the south.

These natural features block moisture from the Pacific Ocean. They force air to rise, cool, and dry. As a result, the air pressure increases. This leads to fair weather and clear skies.

The valley's shape also contributes to temperature fluctuations. Cold air settles in the valley at night. Warm air rises during the day. This creates a daily pressure change.
