Missouri Illinois Indiana Ohio and Kentucky Facing Multiple Rounds of Heavy Rain Over 7 Days With Totals Topping 5 Inches Across the Ohio Valley

ST. LOUIS, MISSOURI — A subtropical jet is set to drive several days of rain and storms across the Ohio Valley and surrounding region over the next week, with BAM Weather highlighting multiple rounds of heavy rain possible across Missouri, Illinois, Indiana, Ohio, and Kentucky as seven-day totals through June 20 push well above 5 inches across a large portion of the highlighted zone.

Seven Day Rainfall Forecast Shows Widespread Totals Over 5 Inches

The BAM Weather active next 7 days graphic valid through 6/20/26 at 3PM shows a massive circled zone of heavy rainfall covering St. Louis, Springfield Illinois, Indianapolis, Louisville, Lexington, Cincinnati, Columbus, Nashville, Knoxville, and Memphis. Purple and dark red shading within the circled zone indicates totals ranging from 5.75 to 10 inches across the core, with surrounding red shading reflecting 3.25 to 5.75 inches.

The subtropical jet is the driving mechanism behind this extended wet pattern, funneling repeated rounds of moisture-rich storm systems across the same corridor through the seven-day period.

Multiple Rounds of Heavy Rain Possible Across the Circled Zone

Forecasters are explicitly flagging multiple rounds of heavy rain as possible across the highlighted region, meaning communities within the circled zone could see repeated bouts of significant rainfall stacking on top of each other over the coming week. Many areas within this zone are expected to see totals exceeding 3 inches, with the wettest pockets potentially reaching into double digits.

The combination of a persistent subtropical jet and multiple storm rounds raises the potential for flooding concerns across the Ohio Valley and Mid-South as the week progresses.

Detailed Week Ahead Trends Coming in Tomorrow’s Report

BAM Weather is preparing a detailed breakdown of the week ahead trends in their agricultural weather report set to release tomorrow afternoon. That report will provide further detail on timing and placement of the multiple rainfall rounds expected across Missouri, Illinois, Indiana, Ohio, and Kentucky through June 20.

Residents across the highlighted corridor should monitor rainfall totals and any flood watches closely as this active pattern develops over the coming week.
