The snow storm to our west, here on the 15 anniversary weekend of the Blizzard of 1993, is developing mainly as expected today. Strong upper-level disturbance is bringing moderate to heavy snow in Arkansas and northern Louisiana today. The latest radar shows this.

Some snowfall reports coming in from Arkansas by 1230 pm…

Evening Shade, AR 10″
Paris, AR 9″
Booneville, AR 10″
Mt. George, AR 14.5″
Newton, AR 12″
Baxter, AR 4.2″
Searcy, AR 10″
Stone, AR 18″

The main upper-level disturbance is moving through Louisiana, but a second one, now in Kansas, will catch up to the main one overnight.

It still looks like the best phasing of cold air and heavy precipitation will be to our north and west over the next 24 hours, from northern and central Mississippi into middle Tennessee and Kentucky, where up to 7″ of snow is possible. However, this is a very intense weather system, with very cold air aloft. As James pointed out this morning, the air over Alabama will be a little bit unstable, so we may see some convective bands of snow between midnight and 6 am, and some spots may receive heavier snow than others. A clap of thunder is not out of the question.

Early estimates would be for snowfall amounts averaging 1-3″ north of US 278, around 1″ along I-20, and a dusting maybe as far south as Montgomery. The snow may move into west Alabama by 7 pm, and into BHM by 11 pm.
