Chilly for the End of 2012

No, the title does not project the end of the world, just the end of another year! Wow, hard to believe we’re about to put another year behind us. And what a year it was, too.

Clouds are expected to hand tough today as the trough axis aloft finally swings by. Because we have a little leftover moisture, a few snow flurries may get squeezed out of the atmosphere as the trough axis comes by. But these situations do not produce any significant snowfall events.

We should clear out and with the wind diminishing, Sunday morning is going to be a cold one with a low in the lower 20s. That means some of those colder locations will dip into the teens. We begin a slow warmup on Monday as a new system begins to take shape. Monday should be a day of increasing clouds with rain chances increasing in the afternoon and rain likely into the overnight hours and New Years Day. It’s likely that you will need an umbrella on January 1st as a wet day is in store for Central Alabama.

The wet weather should be slow to move out due to the upper flow which stays southwesterly. This means we need to keep a chance of rain into January 2nd but it looks like the boundary should sag far enough southward on the 3rd to end the rain chances.

Another substantial trough is forecast to move into the Lower Mississippi River Valley on Friday and across our area on Saturday, but the atmosphere is likely to be dry. This brings us another shot of cold air but for now it looks like no precipitation.

Rainfall with the New Years Day event is likely to bring about an inch of rain to most areas. Since we will be ending 2012 with a deficit in the rain totals, that will be a nice start to 2013. No specific area for severe weather threat from SPC, but they do have a marginal area of concern over the Florida Peninsula.

Voodoo is looking interesting. We stay very active with a strong system around the 8th and then a change to a broad long wave trough over the Mississippi River Valley which has a very cold look to it. But the models have a tendency to shift around that far out, so we’ll see what the next runs tell us.

The next Weather Xtreme Video should be posted Sunday morning by 9 am or so. You can catch my forecast on ABC 3340 at 6 and 10 pm this evening. I hope you have a good day today. Wrap up against the cold. Godspeed.
