NWS Birmingham continues a WINTER WEATHER ADVISORY until 12:00 pm Monday for the following counties in Central Alabama: Fayette, Lamar, Marion, Pickens, Tuscaloosa, Walker, and Winston.
Snow is expected this morning over the advisory area, before gradually mixing with or changing to rain into the afternoon. Total snow accumulations generally less than one half inch, with isolated amounts up to one inch closer to the Mississippi state line. Plan on slippery road conditions in the advisory area. The hazardous conditions could impact the morning commute.
For the rest of Central Alabama, the northeastern, central, and southwestern parts of the area could potentially see a wintry mix (snow, sleet, and/or rain), while the southeastern parts will only see rain.
Projected temperatures as of 3:00 am show that nearly all of Central Alabama will be above freezing except for the extreme north-central and northeastern corner of the area. By this run of the HRRR, Cullman and Haleyville will be right at 32 degrees. This model run also shows that all locations will be back above freezing by 10:00 am. There may be some evaporative cooling that may not be taken into consideration and therefore those temperatures before sunrise may dip into the upper 20s, but cloud cover throughout the evening has not allowed the temperatures at this point to get as cold as first forecast.
The HRRR is also trying to keep snow falling over the northwestern corner of the area and up into North Alabama at midday. The NAM is showing showers and a few flurries, which I believe will be the scenario as those temperatures rise.
I’m with you from now until 9:00 am this morning with any updates.
