The current 30-day precipitation totals throughout the US corn and soybean belt have been considerably beneath regular. The US corn-production weighted precipitation is at 50% of regular over the prior 30 days. The rainfall deficit has resulted in low Mississippi River ranges at St Louis, probably imperiling southbound grain barge shipments.
The 2nd graphic reveals present river ranges (crimson line) at St. Louis superimposed on an evaluation of corn + soybean weekly transport totals at St. Louis as a fraction of the annual most weekly transport complete since 2005. i.e., the Y-axis is a normalized worth. The graphic reveals the "cliff" that develops when the river degree is just too low to permit grain barge passage.
Present forecasts present precipitation for the counties of the Higher Mississippi River drainage basin, however not sufficient to get rid of future river dangers within the quick time period.
