Old Man Winter takes over Alabama tonight.
No significant changes to the forecast. Precipitation in central and SE Alabama may actually start as rain briefly before changing to light snow. Light snow is likely through the evening hours and into the overnight hours. It should shift SE of the I-85 corridor after 2AM and exit SE Alabama close to 6AM. A winter weather advisory continues for the whole area due to potentially significant travel impacts from the snow. See below for accumulation and timing. Plus the latest on the Extreme Cold.
FUTURE RADAR: Hi-res Future radar (HRRR) snapshots do a good job, telling the story. Possible rain, maybe rain/snow mix early evening, then gradually transitioning to snow later in the night, and shifting southeast into the Wiregrass during the wee hours of the morning. Should be exiting the state close to Dawn.
POTENTIAL ACCUMULATION: Most models, including the NAM/WRF and the GFS (and others), depict about an inch to just over an inch of snow, in general, from along and perhaps just north the I-85 corridor, south to about Ozark and Opp. There could be isolated areas close to 2”. That should be the exception rather than the rule. Probably the most bullish of the models is the Euro, which paints close to 2” in spots, in east central and SE Alabama. Even a little snow will cause potentially significant travel impacts. Here’s a peek at 2 models…the NAM and the Euro
EXTREMELY COLD TEMPS AND WIND CHILL: Overnight lows will fall to the teens. Expect some potentially dangerous wind chill readings Wednesday morning, which will fall to the single digits even in south Alabama. A Hard Freeze Warning and a Wind Chill Advisory area in effect.
Nome, Alaska tomorrow morning: 24 degrees, wind chill 19. Montgomery, Alabama tomorrow morning: 16 degrees, wind chill 5. #ArcticBlast #alwx
