Episode Narrative A low developed in the northwestern Gulf of Mexico early on the 9th and tracked east along the Gulf Coast late on the 9th into early on the 10th. A large area of snow spread northeastward during the early to mid evening hours on the 9th, reaching south of the Tennessee River before 8 pm, and along and north of the Tennessee River shortly after. Snowfall rates jumped quickly to 1 to 2 inches per hour and visibility dropped to 1/4 mile or less. Thunderstorms produced very heavy snowfall bursts of up to 4 inch per hour between 10 pm and 1 am with many social media sources and the National Lightning Detection Network (NLDN) reporting several strikes and rumbles of thunder. Weather observers at the Huntsville International Airport reported a 4 inch snowfall between 11 pm and Midnight. Snowfall was mixed in with sleet at times initially as well. The snowfall tapered off to light snow and flurries between 2 and 5 am. Patchy freezing rain mixed in with some of the remaining light snow showers during the morning hours of the 10th, mainly in northeast Alabama.
Snowfall totals ranged from 4 to 14 inches, with heaviest amounts in northwest and north central Alabama, and lessor amounts in central and northeast Alabama generally south of the Tennessee River. The snowfall basically shutdown normal activities and travel across the region with many roads declared impassible or closed. Schools were closed on the 10th and 11th. Temperatures climbed in valley areas to 32 to 34 degrees during the late afternoon and early evening hours, allowing for some main streets to become wet, while rural county roads remained very treacherous or impassible. Black ice became a problem during the nighttime hours of the 10th into the 11th as temperatures either remained below or dipped back below freezing. This was especially the case on mountain roads and rural county roads. In fact, the icing issues were so significant and widespread, that local area emergency situation was declared by emergency management officials for Colbert, Franklin, Lauderdale, Lawrence, Limestone, Morgan, Marshall, Dekalb, and Jackson counties.
Event Narrative Eight to ten inches of snowfall was reported across the county. Most of the heavier amounts of ten to twelve inches were reported in northeastern portions of the county.
