Dry conditions have been recorded across the southern half of Wisconsin over the past month and a half. The driest portion has been southwest Wisconsin where only 10-25% of the normal precipitation has fallen over this time frame. Much of southern WI has precipitation deficits of 3-6 inches during this time. Due to these dry conditions, portions of southwest and southeast Wisconsin have been placed into "Abnormally Dry (D0)" and "Moderate Drought (D1)" conditions via the US Drought Monitor.
