BIRMINGHAM, AL (WBRC) - Thursday, expect cloudy skies and mainly dry weather and temperatures in the upper 40s and lower 50s. This evening, we start to see rain reaching the ground for areas south of I-20 and more precipitation moving up from the southwest through Friday morning.
FIRST ALERT Weather Day Friday due to light snow that could create slick travel conditions.
A Winter Weather Advisory begins at 3 a.m. when rain starts to mix with and change to snow across areas to the south of I-20. We may see all snow by 6 a.m. in many areas under the advisory, and you can see if your county is included on the First Alert Weather app. By mid-morning hours, snow will be falling and accumulating on grassy and elevated surfaces. Remember that elevated surfaces freeze first and we could see slick spots developing on bridges and overpasses.
Precipitation looks to taper off from northwest to southeast during the afternoon hours and temperatures will jump back up above freezing by a few degrees. I anticipate more roadways wet rather than snow-covered, but some will definitely get slushy and slick, especially at higher elevations. If you don't have to travel tomorrow, especially in the morning and early afternoon, then I would go ahead and hold off until you get the all clear that roads are in good conditions.
The advisory will be in effect until 6 p.m. Most of the snow accumulation will occur on grassy and elevated surfaces and will range from trace amounts to ½ inch for areas north of I-20. South of I-20 amounts will range from ½ - 1 inch, and the higher terrain along and south of I-20 and east of I-65 will see 1-3 inches of snowfall.
We will likely continue to make adjustments to this forecast, which means we may be shifting the position of the snow band and adjusting forecast amounts.
Temperatures fall into the 20s on Friday night into Saturday morning. That will cause black ice to form and you'll want to drive very carefully until temperatures warm above freezing during the mid-morning hours.
Sunshine returns this weekend and then we will see another surge of colder air on Tuesday into next Wednesday.
