As waters reach levels seldom seen along the Mississippi and Missouri rivers, and reach new heights along portions of the Arkansas and Illinois rivers, the risk of more levee failures and flooding will continue in the coming days and weeks.
What much of the middle and lower Mississippi River Valley needs is several weeks of dry weather. However, that is not going to happen as the pattern of rounds of showers and thunderstorms is forecast to continue.
Storms will fire over part of flood-stricken areas into midweek. Some of the storms over the High Plains will turn severe.
Into Wednesday alone, an average of 2-4 inches of rain is forecast in the swath from central and southern Texas to central Kansas and Missouri.
An AccuWeather Local StormMax™ of 8 inches can occur from parts of central Texas to southeastern Kansas and southwestern Missouri into Wednesday.
This amount of rain over a few days may not seem tremendous. However, due to the saturated state of the ground in much of this swath and streams and rivers already out of their banks, flooding will be renewed or made worse and can sprawl into areas yet untouched by problems so far this year.
What could make matters even worse is the potential for moisture becoming involved from a brewing tropical feature over the southwestern Gulf of Mexico and unleash even more rain on part of the same area as well as areas farther to the east where rivers are still rising.
Even if this feature fails to gel into a depression or storm, tropical downpours are likely to be drawn northward over a swath of the South Central states from the middle of this week into the following weekend.
There is the potential for rainfall to be doubled depending on the strength of the tropical feature and how effectively a non-tropical storm taps that moisture and drifts along.
The rain will have a significant affect on the crop yields of many different plants over the summer growing season, including corn and soybeans.
This week’s rain could end the time to plant corn over much of the southern Midwest. Corn that is planted this week will likely see a 30 percent drop in yield from the late planting, and the next chance to plant in mid-June will make it too late.
The southern Midwest will see some heavy rainfall during the middle and end of the week. This will continue to delay planting of soybean crops, as another week of delays will be possible for the soybean region.
