:. Indiana Weather And Climate .:
Indiana weather is influenced to a great degree by air currents. Tropical and polar air currents will influence whether a winter is frigid or mild, and whether summer is pleasant or hot and humid. The transition from a cold winter to a hot summer can cause a rainy, stormy spring, complete with thunderstorms and tornadoes. Also, if the polar and tropical air currents meet over the state there is a high chance of severe storms and blizzards in the winter.
Indiana's climate is also influenced by Lake Michigan. Areas near Lake Michigan can be hit by lake effect snowstorms. Lake Michigan also causes the temperatures of the towns near the lake to be about 5°warmer than inland areas. Otherwise, temperatures in Indiana follow the typical pattern of being warmer in the south and cooler in the north, although the variation isn't extreme.
Fall is probably the most certain period for good weather in Indiana. Storms occur less often and are less severe, and temperatures are mild, especially in the early part of the season.
