Hourly Pressure Trends
Track the barometric pressure in Maine hour by hour across the next 6 hourly readings.
Maine's weather is influenced by its location near the ocean. Coastal areas have lower air pressure due to the warm, moist air. Inland areas have higher air pressure from cold, dry air.
Maine's mountains and valleys affect air pressure, creating different weather patterns. Mountains force air to rise, cool, and form clouds, leading to rain and snow. Valleys get cold air from Canada, making them colder than coastal areas.
In winter, cold air from Canada dominates, bringing low pressure and cold weather. In spring, warm air from the ocean pushes north, raising air pressure and temperatures. Summer brings warm, humid air and high pressure. Autumn sees cool, dry air from Canada, lowering air pressure.
Maine has a humid continental climate, which means large temperature differences between seasons. This leads to varying air pressure patterns, influencing Maine's weather.
