BR and our bridges mean freezing precip is an everything is shut down kind of situation. If we have to deal with that, better last December and the 4" vs last January's brutal cold and a pile of graupel.

The new GFS has widespread snow for the BR area tomorrow morning, why is everyone backing off on predictions?

Those 6 hour maps can be misleading with showing snow. I find this to be more useful. As you can see, it shows precip ending with temps at 36 degrees. And 850 temps are just above freezing. No snow from that.

The new GFS is all alone, has been overdoing the set up for days. It'd be a hell of a coup if it got this right. Just looking at the ensemble results from the GFS and Euro, fewer than 10% have anything for BR much less south of here.

If everything else was wrong, it's a great look for the new GFS but it would be folly to forecast based on that outlier.

BigB above is dead on with critique of the six hour maps. It's why I've been grabbing GFS soundings to confirm the snow the six hour maps are showing. I've only seen a run that was in any way in the ballpark.

Rapides will announce school closures. There is no way they put buses on the road in the dark without knowing about all roadways.

Too soon of a cut off or the models were way too aggressive on the cold. HRRR has BR at 50 when that run ends. Not trusting that just yet, despite agreeing with my position south Louisiana goes snowless.

A 2 hour delay should suffice, but I'd put money on St tammany closing the night before, and tangi closing the morning of, when everyone is halfway through getting their teenagers up instead.

I fielded a question about central Mississippi somewhere in the three or four threads that came up about this. Someone cares. Hell I care.
