Tracking roving bands of snow showers

Don't expect them all the time, and even some sunshine in between, but this weekend's wintry feel is real.

Good Saturday morning to one and all. I hope you find this weekend very restful. I know that's what I'm hoping for myself ;-)

The cold air continues to flow into the region today. Expect temperatures to struggle to the 30s during the day, and near 20 at night.

As far as the snow showers are concerned, we're in a little bit of a lull pattern, as a wave of them have already worked through the region, and another is getting ready to make the march off the lake shores and rotate down in. That process will take a while, so we can track it on the radars below. Here's how the NAM is advertising the wave coming in later tonight:

NAM - Saturday Evening NAM - Early Sunday

It may not look like much (and for a bunch of us in valleys it may not end up BEing much), but in the cold air regime we'll be in, the snow ratio of the precipitation will be highly inflated. Normally, it's about 10-to-1, which means 1" of liquid water precipitated out of a cloud results in 10" of snow on the ground. However, it's possible we can get to 20- or 30-to-1 today and tomorrow, which means 1" of snow can fluff up out of around 0.03" of liquid.

I like the NAM when it comes to snowfall, as it has a better grid-space resolution than the GFS (essentially they're showing the same thing if you're curious, just the GFS is all blocky in appearance)

This map demonstrates the fickle nature of a snow-band coating. Whenever they come across they look pretty, but fade quicly. Only the ridgetops really have a shot at anything sticking, and even at that it's the WV mountains only that are looking at the shoveling. This is why this can be a great ski weekend. All the lowland roadways leading to the resorts are just fine, and once you hit the slopes it's a winter wonderland with fresh powder to go around.

The possibilities for snow end on Sunday, and we'll be staring down our next weather maker for early next week.

GFS - Early Tuesday GFS - Late Tuesday

This one is a rain maker at first, owing to the nice surge in temperature we'll feel on Monday. Following the passage of the front, we'll be in line to receive snow showers off the back-end of the system. Keep in mind though, this particular part of the pattern has been failing us this season. We'll have to see just how well Lake Michigan gets involves as to whether or not we can another good dressing of white around here.
