Friendly reminder.....Thats showing green because there isn't enough moisture in the snow growth region to actually snow. it comes down as some drizzle/light rain. yes it will freeze on contact with temps below freezing.

That happened here in Baton Rouge during the storm system on 1/17/18. Rain changing to snow by 4pm, but moisture got scoured out by 8pm. Result was it was just tiny ice pellets near the end.

Shouldn't it show it in pink then? I have never heard of this until now.

OK one more time. That isn't rain on the back side. In fact it isn't anything on the back side. That is an 6 hour QPF map with precip determined by the temp taken at the time the image was produced.

And

Oh look a pony.

Just to quote this post again. That above is a QPF map, the one below is simulated radar and radar with precip type overlay.

You can see the system shaping up nicely now.

The front is easily visible and looks healthy. You can easily make out the energy down in the GOM that will enhance the band across Mississippi/Alabama.9E0582DF-D216-4CB3-9135-0AF41CF226C2.jpeg

It’s time to now cast guys! Radar is lighting up in a few hrs! Enjoy the ride and don’t let the frustration of “it could be more” ruin a nice little snow tomorrow!
