Rain Changing Over To Snow on Sunday


Latest Video Forecast

Snow Chances Sunday

As we move through the morning, temperatures will slowly fall. As cold air moves in from the Northwest Sunday, rain on the backside of the low will transition to a rain/snow mix or occasionally all rain. Where there are heavy enough bursts of snow, accumulations will occur.

Our “Best Guess” Forecast

We think the best chance for this will be in North Alabama, particularly in the higher elevations in Jackson and DeKalb county, but patchy snow accumulations will be possible in Central Alabama as well, particularly north of I-20, and in the higher elevations in Talladega, Clay, Randolph, and Cleburne counties. For most of Central Alabama, we would not expect travel issues if this is how things play out, but there could be some isolated problems Sunday night and Monday morning, especially in higher elevations north of I-20.

Again, we want to stress that many people will miss out on snow in this scenario, but there could be a few spots with some sticking snow tomorrow, and there could be some travel issues where snow sticks to roads and bridges Sunday into Monday morning. IF this scenario plays out, this will be a low-impact event for Central Alabama, but some scattered travel issues would be possible.

Worst Case Scenario Forecast

While we don’t think this is the most likely scenario; the line between a cold rain and light snow accumulations, and a heavy snow event is pretty small. A degree or two warmer or colder a few hundred feet above our heads will make all the difference. Because of how small the margin of error is, I want you to be aware of what we think the “worst case scenario” would be for Alabama. Heavy rain would transition to very heavy, wet snow in the morning, and continue into the afternoon. Snow totals could exceed 6 inches in North Alabama, leading to power outages, downed tree limbs, and road closures. Across most of Central Alabama, snow totals of 3 inches or more would likely shut down some roads and make travel dangerous on roads that remain open.

I want to stress this is *NOT* the most likely scenario. It’s just a possible scenario, and one we want you aware of. Make sure you keep up with the weather Sunday and be prepared for forecast changes, just in case.

Next Week Outlook

High pressure will build in on Monday and Tuesday. There could be some icy spots on the roads Monday morning. Then we will be sunny and cold on MLK Day, Monday with high temperatures in the mid 40s. Tuesday will stay sunny with highs in the 50s. A cold front will move across Alabama on Wednesday with scattered showers and highs near 60°. We will dry out on Thursday and turn colder with highs in the 40s. We’ll see a few more clouds and perhaps a flurry Friday as things get cold again as we head into the end of the week.
