Severe storms threaten millions from Texas to Missouri ahead of Election Day

A multiday severe storm threat has millions across the central U.S. on alert again into the overnight hours.

Severe thunderstorms erupted once again Monday and will continue overnight from northeastern Texas to southwestern Missouri, according to the FOX Forecast Center. Tornadoes, a couple of which may be strong, and damaging winds will be the main hazards with any severe storms.

Several Tornado Watches and Warnings were issued Monday across the severe weather risk zone.

The National Weather Service reported a 94-mph wind gust in Talala, Oklahoma, on Monday afternoon as a tornado-warned storm moved through the area.

As of Monday evening, the National Weather Service had received at least three reports of tornadoes in parts of northeastern Oklahoma and northwestern Arkansas.

According to the National Weather Service, some homes were damaged about 3 miles west of Sperry, Oklahoma, on Monday afternoon in what it called "potential tornado damage."

Most of these storms will likely form into a line overnight, but conditions may allow for supercells out ahead of the line. According to the FOX Forecast Center, this could lead to tornadoes, some possibly strong, along with damaging winds.

The severe weather threat should decrease by early Tuesday as the storm system moves out of the area.

As the large weather system continues its eastward trek, it's also bringing another round of torrential rain to the central U.S. This will create a broad corridor of moisture stretching from Texas to Michigan.

The Ozarks region, in particular, could experience even higher rainfall totals due to terrain-enhancing effects. As the storm system moves northward, it will gradually weaken but is still expected to deliver rain to areas as far north as Wisconsin and Michigan.

Given the recent significant rainfall in parts of western Arkansas and southern Missouri, repeated heavy rain could elevate the flood risk in these areas. 

Flash flooding was ongoing in east-central and southeastern Missouri on Monday, according to the National Weather Service office in St. Louis. A Flash Flood Warning was in effect through Monday evening for parts of Jefferson, Washington, Madison, Sainte Genevieve and Saint Francois counties. 

While rainfall totals through Monday night are anticipated to be lower than the weekend's, additional heavy rain in the same regions could exacerbate flooding concerns.

In St. Francois County, Missouri, officials issued voluntary evacuations for Iron Mountain Lake due to the possibility of a levy failing near the town. In Bismarck, Missouri, the Bismarck Fire Protection District responded to multiple water rescues Monday morning, the agency said in a Facebook post. 

The fire protection district posted photos of the flooding. In one image, a truck is seen attempting to drive through high floodwaters.
