Focus on the Weekend..
* The rest of the work week looks fairly tranquil. Highs will be cool, but nothing terribly cold at all. A few high clouds will move overhead late tomorrow and into Friday.* Our focus here will be on the weekend. A negatively tilted trough will be pivoting through the central U.S., spawning a surface low in the central Plains Saturday evening. Showers and thunderstorms will form to our west Saturday afternoon and begin moving across Mississippi and Alabama.
* Computer model guidance continues to disagree on the exact evolution of this system. The NAM (North American Mesoscale) model suggests that the rain and thunderstorms will hold off until Sunday, while the GFS is a bit faster - it brings thunderstorms into central Mississippi by Saturday evening.
* Instability will be limited, but there should be enough to warrant at least the chance of strong thunderstorms Saturday night and early Sunday morning. We'll continue to watch the latest computer model guidance in coming days...
