Midwest Drought Summary
With a warm and moist air mass in place ahead of multiple storm systems affecting the region between Friday and Tuesday morning, heavy precipitation fell over much of the Midwest region, particularly in Missouri, Illinois, and Kentucky. Heavy precipitation persisted beyond the Tuesday morning cutoff along and behind a slow-moving cold front; any precipitation after the Tuesday morning cutoff will be accounted for in next week’s USDM. One-category improvements were made in parts central Illinois because of recent rains and low evaporative demand. Slight reductions in severe and extreme drought were made in south-central Missouri and north-central Arkansas, as streamflow and 90-day rainfall deficits no longer supported severe and extreme drought in the respective improvement areas. Elsewhere in Missouri and Arkansas, seasonal-scale precipitation indicators did not yet support improvements. Because of dry conditions between one and four months in west-central Minnesota, abnormal dryness was expanded there.
