December 2 2020
The storm that cleared out today left us with chilly air and a thick fresh blanket of snow from western Maryland and into the Ohio Valley. The next storm will come from the Gulf of Mexico and arrive on Friday. This will bring our region heavy rain! To give you some perspective, here is the rainfall forecast from the European ECMWF Model:
Storm Forecast: Heavy Rain
But before winter lovers get completely bummed, there are signals of colder air I want to show you.
To do that, we must first look at the snow on the ground reported this morning.
The snow that fell, overachieved. The top total in Garrett County was 10 inches in McHenry. But there was a large region on the other side of the mountains with 4 to 6 inches of snow. When we get our next source of cold air, it will be supported by whatever snowpack is left over.
USA Snow Coverage
Snow reached northern Georgia, the mountains of Tennessee and North Carolina, and up to the Great Lakes. While some of this will melt over the next two days, the northern snowpack will hold on.
Why is this important?
The next storm will track south of Baltimore. Under normal conditions in the winter, this would be a colder snow track. But the air in place is not cold enough. There will be COLDER air racing in to catch up to the storm.
As of now, the modeling supports this to develop a snowstorm ‘after’ passing us and reaching New England.
But, we need to watch that cold air. There will be marginal cold that can provide a mix with snow at the very end of the storm on Saturday. But I do not think the models are handling this well. I also think the snow pack will play a role with the cold air available, and the speed it arrvies.
Here’s a look at the Surface Low coming out of the Louisiana Gulf region, and reaching the East Coast. I’ve highlighted the leading edge of the COLD AIR, which is represented by the 540 dm Thickness Line. This is often used in the winter for where the atmosphere can support frozen precipitation.
