Good Tuesday afternoon! It has been a mild day across Alabama, with temperatures well above average for early January. A strong cold front is fast approaching Alabama from the northwest and will arrive tonight. Temperatures will drop into the 40s late tonight.

Wednesday will be a chilly and mainly cloudy day, with highs struggling to reach 50 degrees. A sharp northwest wind will make temperatures feel even colder during the day. Expect temperatures to drop to near freezing by Thursday morning. Skies remain partly sunny on Thursday, with a high around 50.

Not much has changed in my thinking on the risk of a winter storm across portions of Alabama sometime Friday or Friday night.

Here’s the latest… A deep upper air trough will dig across the central and eastern US, sending cold air south. We’ll start to notice the cold air on Wednesday, as the first surge of chilly air reaches us. Meanwhile, an upper air disturbance will swing around the base of the trough providing uplift and sparking the development of a surface low in the northern Gulf on Friday. The surface low will help to spread moisture northward into central Alabama. A surface high to our north will pump colder air into Alabama at the same time.

Rain should break out over south Mississippi and south Alabama sometime during the day Friday or into Friday night. As the rain spreads northward into the cold air, there will be a transition zone develop of a wintry mix somewhere across central Alabama, with the potential of all snow to the north of the wintry mix zone. Models indicate at the potential of accumulating snow somewhere across north or central Alabama Friday evening into early Saturday. Unfortunately, depicting that transition line this far out will be tough, so I highlighted most of west and central Alabama in the possible winter storm area. This will change as we get closer and as forecast confidence increases. Keep checking back with us as we get closer to the event for more details on possible accumulations and where the snow will fall and where the rain will fall.
