Watching Saturday

From the deep freeze to severe weather in just a few days is very typical around Arkansas. We have the potential for severe thunderstorms Saturday after lows in the single digits and teens the past couple days.

There are limiting factors, but there are things which really stand out to me and I have concern. One is what's called a strongly negatively tilted trough. This can increase the parameters for spin in the atmosphere. However, there are limiting factors too and that's the lack of instability, especially if clouds and rain start the day. Let's hope that happens.

The greatest dynamics may be north while the greatest instability will be south. Where these overlap (not exactly known at this time) will have to be watched.

The Storm Prediction Center has outlined a large portion of the central U.S for some severe weather Saturday. I have outlined an area in orange with what the models are showing as the greatest instability. This will likely need to be corrected a little as we get closer to Saturday.

Most of the rain and storms should exit from west to east Saturday afternoon. Stay with Channel 7 for the newest information.
