Snow arrived in North Alabama a little after midnight Monday morning. By 2:00 am cars and roofs were already covered in the I-65 corridor and west to the Mississippi state-line. As of 8:00 AM snow is still covering mostly just grassy surfaces near and west of I-65.

We expect warm air to overtake any cold air still in place by lunchtime today, leading to a transition to all rain for everyone in North Alabama. However, should cold air linger for an extended period of time, additional accumulations and impacts will carry over into the afternoon. On the other hand, drier air infiltrating North Alabama from the northwest could cut off moisture being pumped into the region, thus lowering our snow chances and keeping most of the precipitation as plain rain.
Warm ground temperatures will help limit major accumulations and travel impacts. One thing to monitor is that bands of heavier snow can overcome warmer ground temperatures allow for snow to cover roads, especially secondary roads with less traffic. Regardless of snow oor no snow on roads give yourself extra time to get to your destination Monday morning, as roads will be messy wherever you are. Lingering rain comes to an end Monday evening. The rest of the week looks quiet with highs back into the 50s and lows in the 30s.
