WILD MONDAY: Unfortunately, we had four fatalities in Alabama from the storms yesterday and last night; all of the deaths came at Rehobeth, in Houston County just south of Dothan. National Weather Service survey teams will be in that area this morning to determine the size of the tornado. There was also considerable damage at Gulf Shores from a possible tornado, and some places had more than 6 inches of rain. For a time Jackson, in Clarke County, was under a flash-flood emergency.
Today will be much calmer, but clouds will linger for much of the day with a chance of a little drizzle or light rain in spots early this morning. It will be a mild January day with a high around 70 degrees.
COLDER AIR ROLLS IN TOMORROW: A gusty north wind will usher in much colder air. Many North Alabama communities will hold in the 40s all day; the sky will remain generally cloudy with only a limited amount of sunshine. By Thursday morning we will drop below freezing, with a low in the 28- to 32-degree range. The day Thursday will be cool and dry with a partly sunny sky and a high in the low 50s.
ARCTIC AIR ARRIVES FRIDAY: Some of the coldest air so far this season arrives Friday; the Global Forecast System is printing a high of only 36 degrees for Birmingham with an increasingly cloudy sky. And, as a wave of low pressure forms near the Gulf Coast, the stage is set for winter weather issues for the northern half of Alabama.
POTENTIAL WINTER STORM: We all know we have a limited skill set in dealing with wintry precipitation in Alabama, especially four days in advance. So there is no way to be extremely specific now, but with all global models on board, we can’t ignore the potential.
WHAT WE CAN TELL YOU NOW: There is a decent chance of accumulating snow or sleet somewhere over the northern half of Alabama Friday afternoon, Friday night and into early Saturday morning. However, it is simply too early to forecast accumulation amounts or exact placement.
Temperatures should fall well below freezing Friday night, meaning this has potential to be a “high impact” event with travel woes. This system will also have potential to affect other states across the southern U.S.
I usually draw up the first “accumulation potential” map once we get within 48 hours of an event, and that will be tomorrow night. For now, we can just tell you confidence is growing in the potential for a winter storm that could affect parts of North and Central Alabama. Stay tuned.
Sunday will be cold and dry, with a high in the 40- to 45-degree range.
NEXT WEEK: The first part of the week looks dry with a slow warming trend.
