We've been fine-tuning the forecast for this weekend. If you haven't heard, there is a threat for snowfall late Friday into Saturday. The forecast rumor-mill is probably a bit more interesting than the actually forecast. This particular system is very moisture starved which means little in the way of measurable precipitation. However, what we are lacking in moisture we are making up in cold air. The 540 thickness line makes its all the way to Florida this weekend.
The best chance for seeing a dusting of snowfall (mainly in the grassy areas) will be areas north of I-20. Many places will not even see any snowfall accumulate. If you are traveling to Northeast Alabama including Jackson and Dekalb Counties - it's possible you could see 1+" of snowfall because of the higher elevations.
Our RPM model is indicating the best chance of snowfall to occur between 3am and 7am Saturday. The most accumulation based on the model would be areas East of I-65. We are not anticipating travel issues since the window for snowfall will be very short-lived.
The threat for snowfall should end Saturday afternoon with clearing skies toward the evening. Highs on Saturday will reach the lower 40s with overnight lows Sunday morning falling into the mid 20s. Sunday looks primarily sunny with highs in the mid 40s.
We'll keep you updated.
