Wednesday Snow?

Here is an image from our friends at the National Weather Service that shows how the vertical temperature profile helps determine precipitation type.

A big winter storm is moving across Central and Southern Texas. DFW is on the northern fringes of the storm, but its close enough to bring a quick morning burst of snow and ice.

The big difference between today’s snow and Monday’s ice is the vertical temperature profile of the atmosphere. Today, below freezing temps extend all the way from the ground to the clouds. On Monday, and over the weekend, there was a layer of above freezing temperatures that melted the snow as it fell, but when this melted snow hit the below freezing ground, it froze and put that layer of glaze ice on parts of North Texas.

Back to today, our snow will taper off to flurries by noon, but we have a few more chances for some wintry weather all the way through the weekend.
