Inland Waterway Weather Report

Weather Highlights: 

• Upper Mississippi/Red/Souris: Quiet weather over much of the weekend will give way to a strong weather system moving in on Sunday Night. Expect widespread rain to begin the week, though not especially heavy. Generally quiet weather returns thereafter as high pressure settles in.
• Middle Mississippi Valley: Quiet weather is expected through Saturday. Another weather system sweeps through the region by Sunday night, bringing more unsettled weather, possibly severe, to end the weekend and into next week. At this point the severe weather threat is focused well west of the mainstem into Nebraska, Kansas and Oklahoma.
• Lower Mississippi Valley: After an extended period of dry weather across the lower basin, heavy rainfall is forecast the next several days as a weather system lingers over the lower basin. At this time, the heaviest rain is focused over eastern Oklahoma, Arkansas, northern Louisiana, northern Mississippi, and western Tennessee.
