Storms and freezing temps?
I'm sure you're scratching your head wondering how we've had two thunderstorm episodes in the last week with wintertime temperatures. While this morning's activity occurred with surface temperatures in the 20's, the temperatures aloft (a few thousand feet above the ground-in the red color on the above graphic) were roughly between 45-50 degrees. That doesn't seem so warm or humid but when you combine the transport of even a small amount of unstable air along with strong lift in the atmosphere, you can get thunderstorms in that warmer layer of air. These storms produced a combination of small hail, sleet and freezing rain over Wichita, making it a crunchy drive into work today.
