The Frozen Alabama Tundra

The Tuesday morning video is on the server:

A northeast wind continued all night, which kept temperatures from dropping into the teens in many places. At this moment, the coldest place around the state is Huntsville with 18. A northeast wind of 8 mph, making the wind chill 8 degrees. Birmingham is sitting at 20 with a wind chill index of 13. J.B. Elliott will round up all the morning lows and post them here in a bit.

The weekend forecast is a bit complex thanks to an Alberta Clipper rolling down into the U.S. The system looks pretty vigorous, but moisture will be backing. We will mention the chance of some light rain Saturday, and maybe a few flurries late Saturday night and early Sunday, but nothing beyond that. The amount of cold air following the system is also in question. The GFS says no cold air, but the forecast package I wrote this morning shows a sharp change to colder temperatures on Sunday and Monday. The solution might be somewhere in between. Just remember the GFS was over 10 degrees too warm on this current airmass five days ago.

Having said that, it does look like the air involved with the clipper is more of Pacific origin, so I might bump my numbers up a little on the afternoon update later today It will be interesting to see the 12Z guidance roll in later this morning.
