The Virgin Snow

Earlier this morning, snow Virga was falling in middle Tennessee. Virga is precipitation that evaporates somewhere on the journey from clouds toward earth. If you were outside earlier this morning, you sensed the air had a 'wet' feel to it. Sometimes the air thousands of feet above the ground is moist enough to produce clouds and rain at the same time that the air closer to the ground is as dry as a bone. So when the snow falls in these conditions it evaporates on its freefall to earth.

But, no need to worry about 'virga' snow now, as the real deal is heading for us as I type this.

Stay safe and warm, and enjoy the snow! I just hope we don't get the ice that is being forecast.
