As expected, showers have begun to develop and dot the radar across central Alabama just after 12 noon. What's interesting is the motion of the storms - from northeast toward southwest. This is certainly not the direction of movement you would expect to see from an atmosphere that generally flows from west to east.
Looking at the upper air charts, a small rotation at 500 millibars has formed right over central Alabama. The center of the counter-clockwise rotation seemed to be located around Montgomery, so storms northwest of Birmingham were moving northeast to southwest while storms in east central Alabama along both sides of Interstate 20 were moving westward.
And none of these were barn burners. Most were moving slowly at less than 20 mph or so.
So today is one of those days that you don't want to watch the western sky for the approach of storms, but rather the eastern or northeastern sky.
The weather can be just downright fascinating at times. As JB says, life goes on.
