Cold Front Dropping South Across the Western U.S.; Watching Threat for Tornadoes and Flooding in the South

A cold front will push south across the Western U.S. into Tuesday with mountain snow and areas of gusty to high winds. An area of low pressure will form along this front on Tuesday and bring a potential for severe thunderstorms with tornadoes and excessive rainfall in the lower to mid Mississippi River Valley. To the north, heavy snow is possible in parts of the upper Midwest. Read More >

June 2015 was an extremely wet month for portions of northern and central Illinois and northwest Indiana. In fact, the excessive rain amounts in portions of our area as well as across the rest of Illinois and Indiana helped this June become the wettest June on record for both Illinois and Indiana.

After an abnormally quiet May with regard to severe weather, June roared in with several severe weather and flash flooding episodes—some of which were quite significant. The graphic below recaps some of the bigger events, including the softball size hail in Minooka that fell on June 10th and the June 22nd tornadoes.

NWS Chicago ended up issuing a total of 101 Severe, Tornado, and Flash Flood Warnings combined in June, tied for the 2nd most for any June in at least 30 years. Of those 101 warnings, 17 were Tornado Warnings, also the 2nd most the office has issued in any June in the past 30 years. The most impressive statistic is that 25 Flash Flood Warnings were issued in June, the most on record ever issued by this office in a single month! That is no surprise given the amount of flooding parts of the area dealt with. Overall, June 2015 was one to remember.
