Friday is the earliest I feel comfortable mentioning any widespread sunshine for us. In the meantime, we're expecting clouds, fog, rain, and even a few snow showers. Yikes - a few snow showers! Don't get too excited yet. This is one model solution and even then it would be a light snowfall for the Northern portion of our viewing area.
Both GFS and NAM are indicating a good chance for rainfall beginning tomorrow night into Thursday. Forecast models have continued to move the rain chances farther north. The heaviest rainfall will be south of I-20.
NAM critical thickness values are indicating a brief changeover from rain to light snow showers across Marion, Winston, Cullman, Etowah, and Blount Counties. As you can see from the map, the most abundant moisture will remain south of the freezing line on Thursday. While this is something to monitor, I do not foresee any travel issues with this event. If we see any snowfall, it would likely be short-lived during the later morning and early afternoon for our northern counties.
For most of the the Fox6 viewing area temperatures will be well-above freezing during the time we have precipitation.
Through our weather graphics system, I have plotted where we "could" see some snowfall based on the NAM output.
Again, this is nothing to get alarmed about. This is a small chance for snowfall based on the output of one model. As part of the larger picture, I think we'll see more widespread rain Thursday - especially prior to 3pm. Clearing skies are expected late Thursday night with the return of sunshine on Friday. The weekend is looking drier and warmer with highs in the upper 50s to lower 60s.
Weekend Forecast: Mostly sunny with chilly mornings. Lows will be in the lower 30s with highs in the upper 50s to lower 60s. We should continue to see sunshine on the Martin Luther King, Jr. holilday Monday.
Fox6 will have a full rundown on your forecast coming up on our news at 5pm.
