…Quick update after reviewing the 12z computer model guidance from the NAM and GFS…

NAM has a massive spread of moisture across much of central and north Alabama.  However, it indicates that the majority of it would likely fall as rain for our area, with a brief changeover to snow possible at the end of the event.  The best chance of this would come east of I-65, and especially along the GA state line.  I believe this scenario is the most plausible, based on the available data.

The GFS is slightly drier and colder, and would suggest a change to snow occurring a bit earlier.  However, it generates less precipitation, so amounts would tend to be lighter.

So, here’s the thinking…we see rain push into our area late Monday into Monday night.  Early Tuesday morning, the rain will mix with or change over to snow.  There is the potential for some light accumulation of snow, mainly east of I-65, and confined to grassy/elevated surfaces.

Temperatures are likely going to remain above freezing throughout the duration of the precip, so roadways should remain simply wet.

Disclaimer… This event is still 48+ hours away, so the forecast can and likely will change at points between now and then.  Should more cold air get involved, via advection or dynamic cooling processes, then more snow is possible.

Here’s a bit of a “first stab” at a map:
