Forecast

Johnstown's weather is affected by its location in a valley, which traps cold air and makes winters colder. This valley shape also blocks warm air from the south, making summers cooler.

The surrounding mountains create a rain shadow effect, making Johnstown drier than areas east of the mountains. This leads to lower air pressure, causing more clouds and precipitation.

In winter, cold air from Canada brings low pressure, resulting in snow and freezing temperatures. In summer, warm air from the Gulf of Mexico brings high pressure, leading to warm and sunny days.

Johnstown has a continental climate, which means big temperature differences between summer and winter. This leads to large changes in air pressure, causing varying weather patterns throughout the year.
