A few updates on this week’s system:
-Models, while not in agreement yet, are converging more to somewhat of an idea of where this low pressure is headed. If all pans out, the center of it will track from Missouri on Christmas Eve to around the Chicago/southern Michigan area by Christmas Day. That leaves a lot of wiggle room for where the heaviest snow would fall in our area. Right now, anywhere from central Minnesota south to Iowa and into Wisconsin would be game for picking up the heaviest snowfall amounts.
-This is appearing to want to shape up as a long-duration event. Some of the data suggests this getting underway Wednesday evening, with light to moderate snow falling through Christmas Eve and into Christmas Day. Worst case scenario, that could mean 24-48 hours straight snow, and even with light amounts of half an inch an hour…you do the math.
-Winds. There’s some concern of winds ramping up and blowing around some of this snow, especially on Christmas Day.
Bottom line: Too many unknowns yet, but if this pans out to what it’s looking like, we could be facing a rivalling Dec 8/9th storm. What I can tell you is that, if you’re traveling, start preparing now for the possibility of very difficult travel come midweek, both driving and flying.
I understand this is a big holiday with lots of people wanting and trying to get home, and we don’t control the weather even though this may seem like we’re punishing you. We’re not. You’ve all been very good this year. Things can change, for better or for worse, so stay tuned, keep checking back, and at least bask in the glory that we’ll for sure have a White Christmas (cue the Bing Crosby song).
