If you glanced at radar tonight and saw "stuff" over your area, but nothing was falling from the sky... You can sleep well tonight knowing that you are not nuts. The radar was detecting snow falling aloft. So, it was snowing... it was just snowing WAAAY up there. As the atmosphere gets a little juicier, we'll see some of this stuff hit the ground. It's going to be VERY light and little (if any) accumulation is expected.
Tonight's radiosonde (weather balloon) from Little Rock shows the dry air. That's a complicated image, but here's what you can take from it... When the two white lines are farther apart, the air is drier. Notice, they are closer higher in the sky (where it is snowing), but farther apart down low (where it is evaporating... actually sublimating)... but anywho, that's a Skew T.
I'm going to sleep now.
