🚨 Saint Louis, Indianapolis, Nashville Weather Alert Feb 13-15 | 100M Hit [1p6n0RLrzJg]
WHAT MAKES THIS STORM SO DANGEROUS: The temperature difference between Dallas TX (70°F) and Omaha NE (28°F) on Friday will be 42 degrees over just 600 miles. When you get extreme temperature contrasts like this, the atmosphere becomes violently unstable. The collision of arctic air diving from Canada with tropical Gulf moisture creates explosive energy - equivalent to hundreds of nuclear bombs worth of atmospheric energy being released. That energy manifests as tornadoes, destructive winds, heavy precipitation, and rapid intensification.
