United States Barometric Pressure Map
Depending on how many places we monitor in United States, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.Trends Today
Here you can see which cities experienced the biggest and smallest changes in barometric pressure today. This helps highlight areas with the most stable or unstable weather patterns.

How is it calculated?
Our volatility “beta” number is generated by an algorithm that analyzes hourly barometric pressure changes. It looks at how much the pressure fluctuates from hour to hour. A beta of 0 means no change, perfectly stable pressure. The higher the decimal value, the more variation there has been throughout the day or over a longer period.
Weather Systems
Large weather systems like high-pressure zones (anticyclones) and low-pressure systems (cyclones) move across the United States. High-pressure systems often bring clear skies and calm weather, while low-pressure systems lead to storms and rain. These systems shift eastward due to wind patterns called the jet stream.
Geography
Geography changes how air pressure spreads out. The Rocky Mountains in the west block or redirect air, creating lower pressure on their eastern side. Flat areas like the Great Plains see fast changes in pressure because nothing stops moving air masses. Coastal regions experience rapid pressure changes as ocean air moves inland.
Seasonal Cycles
Air pressure follows a yearly cycle. In the winter, high pressure builds over cold land in the west, while storms from low pressure track across the country from the Pacific. In summer, the southeast often has steady high pressure that brings hot, humid weather, while pressure drops in the southwest can cause summer storms.
Climate Change
Climate change is changing air pressure patterns. Warming causes more intense low-pressure storms and can weaken some high-pressure areas. This means places in the U.S. may get stronger storms, heavier rain, longer heatwaves, and drier droughts as pressure patterns shift.
Places in United States
You can find your city in the lists below, by using our search, or on the United States Pressure Map above. We're tracking barometric pressure across multiple locations in United States to keep you informed.
Each city includes a pressure status showing whether it's currently high, normal or low, along with two volatility values: one for today and one for the full period, usually 14 days. These help you see how much the pressure is changing over time.
Due to the large number of locations we monitor in United States, we can’t display them all here. Use our search bar if you're looking for a specific city.
