Slight risk today

SPC is showing a slight risk of severe thunderstorms much of Alabama today. Wind fields are more impressive today than the instability. Dewpoints are hovering around 50 in North and Central Alabama early this morning. That will need to change significantly before severe weather will become a threat. The thing to watch today is how much moisture can return from the south prior to the arrival of the trough. The fact that conditions will be most favorable for storms in the afternoon hours is a concern. I am pretty confident that Birmingham and Huntsville will be issuing some severe thunderstorm warnings today and probably a few tornado warnings.
