I've seen that before and that kind of snow can pile up in a real hurry Pretty sure we had that with the Jan 19 storm. It was a weird overperformer iirc. 2 Link to comment Share on other sites More sharing options...

It's new snow coming. I like it because it uses upper air temps to assess accurate ratios. 1 1 1 Link to comment Share on other sites More sharing options...

They will change to a warning when it’s almost over. I actually love it when they play catch up. Link to comment Share on other sites More sharing options...
