Christmas Eve Tornadoes in Alabama

Limestone County 3:33 p.m.

Walker County 4:32 p.m.

I planned on staying away from the blog today but I want to give a quick update on yesterday's storms. Severe parameters seemed to be very marginal. Instability, especially, was very limited. However yesterday was one of those days that proves that if there is enough shear in the lowest part of the atmosphere, tornadoes can and do occur even with marginal instability. As James Spann and J.B. Elliott often say about severe weather, "Expect the unexpected".

Two tornadoes have been confirmed by the National Weather Service, one near Jasper in Walker County and one near Belle Mina in Limestone County.

Here are summaries from Huntsville and Birmingham NWS offices:

HUN: N Belle Mina [Limestone Co, AL] nws storm survey reports TORNADO of F1 at 24 Dec, 03:33 PM CST -- two unoccupied mobile homes destroyed. two large tractor sheds destroyed. large trees uprooted. tree blown over on car at residence. one wall collapsed at small farm home.
