"While chasing a severe warned TS near Kilgore, TX., I saw a large plume of dark smoke rise up in the air near me. I turned around on I-20 and treked off through the woods. It was an oil storage tank area that I found out a short time later had been hit by lightning. One tank exploded and launched approximately 75 feet away.

----------------

The Storm Prediction Center (SPC) says an area from central Texas, through eastern Oklahoma, southeast Kansas, and western Missouri has the best chances for severe weather on Tuesday.

Tuesday's Severe Chances

Tornadoes are a threat due to strong shear, abundant moisture, and CAPE values exceeding 2500 J/Kg. A strong cold front will interact with those unstable conditions to produce supercell thunderstorms. Strong storms may also form along the dry line from central Oklahoma down to west-central Texas.

Severe weather is expected to persist across the southern U.S. through Friday.

SevereStudios will have many streamers in the field on Tuesday. Please check back for updates!
