SUMMARY: A blast of arctic air will bring historically, prolonged periods of cold air and a brief chance at a wintry mix to the region Thursday night into Friday. Temperatures as low as the single digits with wind chills into the negative values.
AREAS AFFECTED: All of north and central Alabama. All of our Coverage Zones
TIMING: Cold temperatures begin Thursday night, until Tuesday (December 27th)
POTENTIAL IMPACTS: Prolonged exposure to temperatures of this degree can lead to hypothermia, broken pipes, and dead/damaged plants.
RECOMMENDED ACTIONS: Prepare now for an extended period of bitterly cold temperatures. Dress in layers if outdoors for an extended amount of time. Wear a hat and gloves. Bring in any outdoor plants to prevent any harm. Cover outdoor pipes and water spigots to prevent bursting, and run a steady drip of water on indoor faucets to prevent bursting. Remember the 3 P’s: Pipes, People, Plants.
Well, where to start. It’s gonna get cold, as in really cold. Wintry mix? Maybe a little, but am not too overly concerned with this. More concerned about the cold temperatures as everyone else should be too. Cold arctic blast arrives Thursday night with a little bit of moisture. This should be enough for a brief changeover to rain/snow/sleet mix as the front passes. GFS hints at little-to-no freezing/snow accumulation, and given the winds that arrive with the front this seems accurate. Even if any snow does fall it will get blown around and will dry rather fast. At this point may see a dusting on elevated surfaces.
Cold weather stays until the 26th, where temperatures begin to rebound. North Alabama still struggle to get above freezing until the 27th.
