Large and dangerous tornado outbreak likely Wednesday

The month of March is known for its extremely volatile weather, as warm spring conditions battle to replace the cold of winter. When and where the collision between the two meet, severe weather and tornadoes are bound to emerge.

This common March collision is on track to take place later Tuesday through Thursday in the southern U.S., with a particularly dangerous severe weather outbreak likely Wednesday and Wednesday night from Arkansas east to Alabama. There's a threat of numerous tornadoes, with a few large and powerful tornadoes possible. For forecasters it is no surprise that that spring severe weather season is starting with a bang. That's because there's still a formidable La Niña event present in the tropical Pacific Ocean, which is typically associated with a more extreme, wavy jet stream and thus a heightened tornado threat.
