BIRMINGHAM, AL (WBRC) -
Many north-central Alabama counties are still under a winter weather warning or advisory until 6 a.m. Thursday.
This is a look at what to expect from "round two" of the winter storm over the next two days.
A Winter Storm Warning is in effect until 6 a.m. Thursday for the following counties: Marion, Winston, Walker, Blount, Etowah, Calhoun, Cherokee, Cleburne, Jefferson, St. Clair and now Shelby, Talladega, Clay, and Randolph.
A Winter Weather Advisory is in effect until 6 a.m. Thursday for the following counties: Lamar, Fayette, Tuscaloosa, Bibb, Chilton, Coosa, Tallapoosa, and Chambers.
The worst travel issues are north of I-20 and especially along the Highway 278 corridor through early today. We have reports of icy roads in Marion, Winston, Cullman, Blount, Etowah, and Cherokee Counties. Elevated roadways are especially problematic. Travel problems will continue to improve today as temperatures climb into the middle 30s, especially south of Highway 278. Areas along 278 will still have travel problems lingering through Wednesday.
We are expecting rain to move in from the west Tuesday evening and overnight. It will be a steady rain, especially along and south of I-20. Temperatures area-wide should be above freezing and the threat initially for travel difficulties is low.
As the air starts to cool, precipitation may mix with freezing rain, sleet and snow to the north for the counties located along the Highway 278 corridor. The majority of the FOX6 viewing area should stay above freezing through the pre-dawn hours Wednesday.
As the air continues to cool across Etowah, Cherokee, Cleburne, Clay and Randolph counties, freezing rain is possible and a light glaze may form by daybreak Wednesday.
There is a threat for a wintry mix along the 278 corridor from east of Cullman to Oneonta to Anniston to Ashland. Freezing rain may be the primary precipitation type there initially and ice accumulation is a concern.
Areas east of Highway 65 and especially north of I-20 will cool first and we'll see travel conditions going downhill there first on Wednesday. A tenth to two tenths of an inch of ice is possible, especially on elevated surfaces like trees and cars across east Alabama.
As the storm system to our southeast strengthens and moves up the eastern seaboard, cold air will continue to wrap around it and will change the rain to a wintry mix and snow westward during the day.
Precipitation will change over to snow or a wintry mix from northeast to southwest and will approach a line running from Jasper to Birmingham to Childersburg to Alexander City by 4 p.m. and then toward Tuscaloosa to Centreville to Clanton after 6 p.m.
Significant snowfall accumulations are possible Wednesday afternoon and night, especially north of I-20/east of 65.
The threat for wintry precipitation wraps up around midnight Wednesday into Thursday morning.
We'll continue to keep you updated as we track another winter storm developing!
