Above-Average Rainfall Expected for Rest of June and July in Illinois

The post from this morning documented the above-average rainfall received so far in June across Illinois. On top of that, the latest NWS forecasts indicate that wetter-than-average conditions are expected for the rest of June as well as July in Illinois.

The first map shows the 6-10 day forecast with Illinois and most of the Corn Belt having an increased chance of wetter-than-average conditions. The second map shows the 8-14 day forecast with the same wet pattern.

The third map shows the month of July with an increased chance of wetter-than-average conditions across all of Illinois. The fourth map shows the three-month forecast for July-September. At that point, the chance for wetter-than-average conditions is confined to western Illinois.
