Indiana saw one of their driest and wettest summers on average within a four year span. What the map doesn’t tell is the inconsistency of rainfall from year to year during the summer. What the key of the map makes it misleading is the fact that it is the most even in terms of rainfall the state gets near equal amount of rainfall on average. The driest portion of the state is generally southwestern Indiana, which generally sees the most precipitation on average throughout the year. This is due to the randomness of summertime thunderstorms that form due to daytime heating. The highest averages in the state tended to be centered around Cass, Clay, Fulton, Owen, Pulaski, and Putnam counties.

Summer precipitation is the most inconsistent of all the four seasons despite the seasonal average from 1980-2020 having the smallest range of 2.6 inches from maximum to minimum average summer precipitation over the select period.

This map takes into account Meteorological winter, which runs from December 1st to February 28th/29th. December and January is commonly the best months for lake effect snow to occur as the largest temperature contrast between the quickly cooling air and the slowly cooling lake water. This can add several inches of melted precipitation to an area’s annual precipitation totals. The warmer large body of water compared to the cool dry air mass of the winter months accompanied by north winds can lead to large lake effect snow amounts. These counties all boarder Lake Michigan to the north and sees higher precipitation totals in the winter due to lake effect snow that affects areas in proximity near the lake. Some locally higher precipitation averages can be found along northern LaPorte, Porter, and Lake Counties. ![]() The trend of southern Indiana receiving more precipitation remains the case for the winter months.
