It will sneak quietly through the Tennessee Valley tomorrow afternoon.
Tonight will be another cold one. Most places will be in the 32- to 35-degree range early tomorrow. Pieces of energy within the trough will rotate through over the next several days, and these pieces of energy will bring reinforcing shots of arctic cold air to the region. This will not amount to anything, but is just a sign that winter is here and colder than normal temperatures may stick around. However, areas along and south and east of Interstate 95, especially towards the shore, may get a little light mix of rain and snow overnight Friday into Saturday. New model data suggests thermal values will be cold enough for some snow across parts of central Alabama.
Accumulation potential will be limited by warm soil temperatures. We won't be seeing any accumulation.
It is early December, so I guess we should be ready for it! The southern edge of the "snow zone" is roughly along USA 80 - Demopolis to Selma to Montgomery to Opelika.
Rain and snow showers are likely Monday.
The best chance of snow is over southeastern MA through early Saturday night.
Not everyone in central Alabama will see snow.
Concerning timing, the precipitation will most likely begin during the pre-dawn Friday, then taper off Friday afternoon.
The Tulsa Christmas Parade is a 2 p.m. Saturday. As an area of low pressure moves northeast hugging the coast, clouds stay persistent for Friday. Accumulating snow looks more likely for Rhode Island and southeastern MA. High: Mid-upper 30s. Overcast skies overnight, with lows in the upper 30s to near 40.
The door to cold weather is now open, and won't be closed anytime soon.
