BIRMINGHAM, AL (WBRC) - BIG CHANGES AHEAD: This is going to be one of those wild weather weeks in Alabama, with an unseasonably warm start and much colder ending. In the short term, we will remain dry through this evening. By the way, be on the lookout for a bright supermoon on the rise after sunset this evening. We should have enough cloud breaks for viewing and for snapping some awesome weather pics! The fog will return tonight but it will be more patchy in nature as lows tumble into the low 50s and upper 40s. I'm still expecting sweater weather in the morning but it won't be nearly as chilly as previous mornings. Sunshine returns tomorrow and this will help temperatures top 70º. Take full advantage of tomorrow because the weather goes downhill on Tuesday. This should time out nicely for the West Alabama Christmas Parade tomorrow night. Clouds will be increasing tomorrow night, with unseasonably mild temperatures throughout the evening in Tuscaloosa.
RAIN ARRIVES TUESDAY: Rain is a pretty much guarantee on Tuesday as a strong cold front enters the area. We will have a thin line of heavier rain, with some embedded thunder marching across the area by the afternoon. I'm not expecting severe weather but there could be a strong gust front (windy conditions) as this boundary crosses the area. Then temperatures will tumble through the evening hours with a steady light rain. So plan on a mild start, with a colder, rainy, and breezy end to the day.
MUCH COLDER WEDNESDAY: We won't really have a major freeze Wednesday and Thursday but the big story will be daytime temperatures struggling to break out of the 40s. Clouds will also linger and this will limit warming each day. Temperatures will drop below freezing Friday morning as the cloud cover decreases. We will also likely wake up to a heavy frost Friday morning.
SNOW FRIDAY NIGHT: The rumors are already flying about the possibility of snow in Alabama Friday night. A clipper system in the northwest flow will lead the next surge of cold air and this could squeeze out some light precipitation Friday night. Many times these types of systems are very moisture starved as they cross our area and temperatures are often above freezing. Bottom line is we won't really know those particulars until the higher resolution model data picks up on this system within the three-day time frame. That being said, I have seen these systems produce snow showers and some brief accumulations, more often over far northeast Alabama. For now, I'm going to include the possibility of a few rain showers locally, with a few snow showers possible north of our area. This could taper off with snow flurries in our area as temperatures tumble. We will have freezing temperatures this weekend during the mornings, with afternoon highs in the 40s on Saturday. We're certainly looking at a more interesting pattern, which is often the case in December, and we will have lots to talk about in my forecast tonight.
