Cold on the Move, Lots of Questions

No Gravatar

There are still lots of questions about what will happen when next week’s Arctic air mass pushes south across the Plains (when, how cold, where). And because substantial overrunning of warm, humid Gulf air is expected, additional questions muddy the situation (rain, snow, freezing rain, when, where).

As warm, moist, less dense air collides with cold, dry, more dense air, it is forced aloft where it condenses into clouds and then precipitation. The vertical temperature structure within this region will determine the type of precipitation: liquid, freezing, frozen or a mixture. Image: Wikipedia.

ImpactWeather’s Chris Hebert attempts to remove at least some of the question marks with today’s StormWatch “Arctic Outbreak” video.
