Hourly Pressure Trends
Track the barometric pressure in Portville hour by hour and stay informed about how it will change over the next 6 hours.
Weather patterns in Portville cause barometric pressure to rise and fall. When a low-pressure system moves in, pressure drops, and when a high-pressure system arrives, pressure increases.
Portville's elevation, 1,450 feet above sea level, and surrounding hills influence atmospheric pressure. The landscape blocks or redirects air masses, affecting pressure variability.
In winter, pressure is often lower due to cold air masses from Canada. Spring and summer bring higher pressure with warmer air from the Gulf of Mexico. Autumn's mix of air masses creates variable pressure.
Portville has a humid continental climate, which means large pressure fluctuations occur between seasons, affecting the weather and daily life.
