A strong storm system is rolling through the southern tier of states. From Texas to Georgia, they're seeing heavy rain and even some severe weather. Numerous flash flood watches are posted for areas of Louisiana, Mississippi, and Alabama. A powerful line of storms is also tracking through the deep south that has prompted severe thunderstorm watch boxes and plenty of severe thunderstorm warnings.
This vigorous low pressure system will eventually track up towards the mid-Atlantic region. Farther south the Carolinas and Georgia down to Florida will see heavy rains and thunderstorms. The snow should get really get going through the morning hours. By noon, as this forecast model shows, the heavy snow can be found from southeast Kentucky to western Virginia. The first image is at 6am on Sunday. Notice not much snow has developed yet.
By Sunday evening, the heavy snow will be tracking right through the heart of Virginia. Many airports in the mid-Atlantic will likely be seeing delays due to the snow. The storm system should exit the coast by Monday morning.
Check out the projected snowfall totals. You can see a bulls-eye of over one foot of snow in the deep purple over southwest portions of Virginia. What's causing this bulls-eye of heavy snow? That area lines up with the Appalachian mountains. Air going up over the mountain provides enhanced lift leading to heavier snow. Look at the Rockies to the west. Notice all the snow out there and the dotted areas of pinks. That's all thanks in large part to the Rocky mountains.
If you're paying attention closely, you may notice a batch of accumulating snow over Western Wisconsin. This map is all the accumulating snow up to Tuesday at 3pm. That means we have some snow on the way. Start the booing or cheering now! There are still some questions as to the exact timing and track of this upcoming low pressure system, but it looks strong enough it could drop several inches of snow across Western Wisconsin...enough to do some shoveling. The precipitation will start Monday evening, possibly with rain mixing in, then changing to all snow Monday night with snow tapering off later Tuesday. So for folks wanting snow, we may finally get our turn this week!
