Severe thunderstorms with possible tornadoes and flash flooding are forecast from the Plains states to the Mississippi, Ohio and Tennessee Valley regions, including much of Missouri.

The National Weather Service (NWS) Storm Prediction Center in Norman, Oklahoma, says the storms are expected to begin Friday afternoon from northern Texas across Oklahoma, central and southern Missouri, northern Arkansas, southern Illinois, southern Indiana, western Kentucky and western Tennessee.

The center said the greatest chance for tornadoes appears to be in western Kentucky and northwestern Tennessee, while there is a slight chance for tornadoes in the remainder of the 142,000 square mile area that includes more than 11.2 million people.

Various flood watches and advisories have been issued for much of the region. For the southern two-thirds of Missouri, a Flash Flood Watch is in effect from this evening through late Sunday night. 

The NWS reports recent rainfall has set the stage for a significant flooding event this weekend. The slow-moving, potent storm system will interact with a very moist airmass to produce heavy rainfall over the weekend. Rainfall totals of 3 to 5 inches are likely with locally higher amounts possible across central and southern Missouri and southern Illinois.  

Heavy rainfall will result in flooding of low lying or poor drainage areas, and ultimately dangerous flash flooding on smaller creeks and streams. Moderate to major flooding is also possible on larger streams and rivers.

The storms also could include large hail and strong winds.
