BIRMINGHAM, AL (WBRC) - Accumulating snow is still expected for our area starting late Monday night to the far northwest and continuing into the early morning hours on Tuesday. Temperatures will be tumbling into the freezing range which will lead to the possibility of hazardous road conditions.
THE LATEST: As of 8 p.m., new forecast guidance continued to show a surge of frigid air and rain reaching Alabama late Monday night. Dry weather will be the story during the day on Monday, with highs nearing 60 degrees. The actual cold front will reach our area around 8 p.m. Monday night. After the front passes, you can expect a big drop in temperatures, with rain developing. The rain is expected to eventually change over to snow, with accumulations of 1 to 3 inches possible during the early morning hours. Snow will likely be falling in many areas at sunrise on Tuesday and the snow should start to taper off to the east by 10 a.m.

IMPACT: Some of the most treacherous travel conditions will be during the morning hours on Tuesday as temperatures drop to freezing and below freezing. The first trouble spots will be bridges, overpasses, and elevated surfaces. We may break into some sunshine by the afternoon, with temperatures hovering near freezing along the I-20 corridor and points south. Temperatures will likely remain below freezing further north. We will also need to keep a close watch on road conditions for the threat of black ice development Tuesday night as temperatures tumble into the teens. Also, plan on an ice cold north wind Tuesday, with wind chills in the teens.
THE REST OF THE WEEK: After a frigid and icy start Wednesday, temperatures will make a nice rebound into the 40s, with sunshine. This should melt away most of the lingering ice and snow. We will have a freeze Wednesday night so we will need to keep an eye out for any residual moisture. We will be tracking a system that could bring a few showers on Friday. Right now it looks like temperatures will be warm enough to support all liquid precipitation, although a few sleet pellets can’t be ruled out initially as the atmosphere moistens-up. Stay tuned for more updates on the winter weather potential and I will be leading off the news at 10 p.m. with the latest.
