Just encountered a nice shower of graupel in Trussville. Graupel is snow pellets. It generally forms when snowflakes encounter supercooled water in a convective environment. So they are more like hail than sleet and are indicative of really cold air aloft.
Numerous reports of graupel across the area from Skywatchers and viewers. Some reports of snow flurries mixed in.
Temperatures are generally in the middle and upper 40s. It is 39F at Haleyville. It is 41F at Vinemont.
Radar shows three main batches of precipitation at this hour…
…one over Fayette and Walker Counties
…one over Blount into southern Marshall Counties
…one over East Alabama’s Cherokee and Cleburne Counties
A lighter patch extended across much of Tuscaloosa County into SW Jefferson County.
Movement is to the ENE.
Temperatures are slowly falling and as the atmosphere cools, precipitation will mix with and changeover to snow as we go through the overnight.
Lots of precipitation back over Northern Mississippi. 39F at Tupelo. 36F at Olive Branch. Precip lightens up back into Arkansas.
