Radar has taken on a different look within the last couple of hours. Instead of patches of light rain, there are now numerous very small convective showers.
These are producing brief but quick periods of sleet. We have had numerous reports of that across North and Central Alabama.
It is cold aloft from about 3,000 feet upward. Upper air charts show substantial cold air advection at the 700 millibar level (roughly 10,000 feet)
So some of the precipitation can be brief small hail due to the convective nature of the showers. The technical name for that is “grauple” which means small soft hail. It is usually quite small. That term (grauple) has been around forever but rarely used in weather information.
Howsomever, our main concern should be daybreak temperatures tomorrow.
