Overview
On Wednesday, February 25, 2015, many Alabamians experienced one of the largest snow storms on record as over 12 inches of snow were unofficially measured along the Highway 278 corridor in Marion County. In addition, much of the northern two-thirds of the state saw snow during the afternoon and evening hours of the 25th, with totals of 1 - 2 inches near Interstate 20 increasing to 5 - 12 inches further north to the Tennessee state line. The highest unofficial measurement came from Guin, Alabama, with 12.7 inches.
A cold front had moved through the region the previous weekend bringing arctic air to the Southeast. Temperatures dropped into the teens and were slow to recover through the first half of the work week due to cloudy skies and several rounds of precipitation Sunday through Tuesday. However, the bigger concern was lurking on Wednesday as a strong gulf system was poised to take a run from Texas eastward through the Carolinas. This system had a tremendous amount of moisture, in fact near the 75th percentile for February, and along with the colder air already in place, brought the threat for a very heavy snowfall.
The northern gulf low continued to strengthen through the day decreasing several millibars as it moved into Georgia during the evening hours. This event began with temperatures in the middle, and in some cases upper 30s, mid-morning on Wednesday, and had to rely on dynamic cooling to change the rain to snow. Thanks to those heavy rates, colder air from aloft quickly replaced the warmer air and rain changed to snow to the delight of most. The interesting prospective of this storm came with the high snowfall rates experienced. Much of the area saw 1 - 2 inches per hour, a rarity for Alabama. The snow was also moisture heavy, making for a very wet and sticky snow, which piled up very quickly. Unfortunately for some, that type of snow also melts very quickly!
This was one of the most challenging forecasts experienced in quite a while. Temperatures from 5000 feet down to the surface were going to be extremely close to either a heavy wet snow or just a cold rain. While most of Central Alabama was disappointed as only rain fell, some experienced one of the largest snowfalls on record that won't be soon forgotten.
