A few showers have developed across North and Central Alabama just after 12 noon. As the radar image shows below, the showers are pretty small, so only a few folks are going to get any rain before the drier air arrives later this evening and early Monday.
Drier air is showing up in the dew point changes upstream from us. Here is a screen capture of the observation from Jackson, TN. You can see the dew point has been falling steadily since 7 am.
Another sign of the drying is the upper air observation from the Shelby County Airport this morning. You can see in the image below that the dew point falls off dramatically around 640 millibars – roughly about 13,000 feet.
