Forecast

Grand Island's weather is affected by its location in the Midwest, where cold air from Canada meets warm air from the Gulf of Mexico, creating changing air pressure patterns.

The city's flat prairie landscape allows winds to travel easily, making air pressure changes more extreme, with rapid drops in pressure bringing storms and rapid rises bringing fair weather.

In winter, cold air from Canada dominates, bringing low air pressure and snowstorms. In summer, warm air from the Gulf of Mexico dominates, bringing high air pressure and hot, sunny days.

In spring and fall, air pressure rapidly changes, causing thunderstorms and strong winds. Grand Island's humid continental climate means it experiences large diurnal pressure ranges, making the weather unpredictable.

The city's location in a region where multiple air masses meet makes its air pressure and weather highly variable, with frequent changes in pressure leading to different types of weather.
