Bizarre forecast

#1 Postby Portastorm » Tue Dec 21, 2004 8:57 am

This morning's forecast discussion from NWS Austin/San Antonio has me scratching my head. With 850 mb temps in every model I have seen supporting frozen precip, they're still forecasting "freezing rain" on Thursday night and Friday.

Aye carumba! :roll:

Is it below freezing above the surface or just right at it?

From what I saw the vertical profile supported snow with 850 mb temps at or below zero. Then again I'll acknowledge I'm not a professional meteorologist and maybe I'm just flat out wrong!! But this forecast of freezing rain really baffles me.
