Well lets dive right into it. The NWS in Huntsville has its entire warning area under a winter weather advisory For Wednesday ranging from 6am-9pm in the Shoals and from 9am til 9pm from I65 to the East on Wednesday. Although we are not expecting a big time ice storm like we had in the early 90s we very well see some ice problems on area road ways and bridges. There does not look as if it will be heavy enough to bring down power lines but be better safe than sorry so be prepared. Some local meteorologists are saying we could see 2" of snow then the freezing rain will take over then our ice problems occur. The NWS is saying little or no accumulation of snow or sleet and less than 1/10th of an inch of ice. So what does it mean it means BE READY FOR ANYTHING. I am not going to touch it with a 10 foot pole. The RPM shows the entire North Alabama area blanketed with freezing rain so we will just have to sit back and wait. I do believe however there is no need to run and stock up on bread and milk with this system just be smart. The one thing we will have to watch for is evaporative cooling.With the dew points as low as they are, some evaporation is likely before the lower column gets saturated, and that could pull temperatures down to levels lower than suggested on guidance. Just something to watch out for. Notice the HPC has the bulk of the ice well to our north tomorrow afternoon and evening. Now on to Saturday>>>>>>>

A surface low will develop and will move out of the Gulf of Mexico into South Georgia Saturday, which is generally the track we like to see for snow over North Alabama if we have enough cold air in place. Right now, it looks like the thermal values are a little too warm for snow, but you never know. Look at the model out puts below for Midday Saturday and the rain snow line is inside NW Alabama with plent of moisture for some snow. Now the European model shows the rain snow line from near Mentone through Cullman down towards Tuscaloosa with all the heavy moisture south of that line. The 850mb temperature ECMWF models does show the cold air back in north Alabama as well. So this is another one where we will be right on the edge (a fine line.) I am not going to post any model outputs on the week of Christmas this time but, it now is trending warmer and no flurries are present on any run. With that said it is still a week and a half away so models will change over and over again. It does show a whopper of a snow/ice storm the 27th/28th so we will see.
