If your normally close to the 528 thickness line, that is where you can see 20:1 snow ratios or better.

18z GFS nice hit for N IL/N IN...

18z NAM coming in pretty good for Saturday Clipper...Sunday Clipper has a 998mb SLP in SW MN @ 06z Sunday.

Yup, Lake Superior is a very deep lake carved out of ancient glaziers. Meanwhile, Lake Erie's average depth is 62ft and about 212 max depth. Lake Superior's avg depth is 82ft and max is 1,332ft. Lot more water by volume.

CFS continues with a brutal February for much of the nation. I does temper the west coast ridge for the 1st week or so in February, but then the ridge appears once again and in return reloads the cold in the central/eastern CONUS. It even has it deeply cold in the center of the nation into the 1st week of March!

12z Euro Monday and Tuesday night temps....

That strong PV over southern Hudson Bay will need to be watched as that can push systems farther south, even miss Chicago. Cold air has the tendency to push systems farther south so time will tell.

The trend for the Clipper to become more juicier on Sunday is on the rise. I think with time, models will come in juicier. Another Saskatchewan Screamer???

Wow, Euro has a 988mb SLP in SW WI!

12z Euro coming in pretty good for Friday's Clipper for E IA/N IL/S WI...maybe 2-3"

^ Nice intense lake plume, could it wobble to the west??? It's possible, look what happened 2 nights ago.

GFS would be ideally the best track for LehS for SE WI/NE IL. Still lots of time to track the Clipper on Sunday. Something tells me we are going to do real well by these Clippers. I think some places may crack 12" if LehS kicks in. This is a wound up potent Clipper.

Money, GGEM is also cold Sunday and Tuesday night, not as bad but still brutal...maybe knock down 10-15 degrees from the Monday night.

12z GGEM is just ridiculously cold for Monday night...showing -30 to -35F in MN/IA/IL...

Nebraska will have their fair share of storms starting in February. The 500mb pattern shaping up next month is prime for coast to coast storm systems and with plenty cold air entrenched.

12z GGEM...

GFS starting to show that active west/east storm track that is giving the Plains much needed moisture that was expected. February could bring some blockbuster storms across the Plains/Midwest/GL region. With a -PNA, not sure if the east coast gets too many snow storms in this type of pattern. Interior locations will probably do better.

12z GFS Snowfall...

12z GFS taking Sunday Clipper on an ideal track through C IL that hits NE IA/N IL/S WI with .25-.30 qpf totals. I noticed that the 528 line is in a prime location to produce very high snow ratios with this Clipper. This one may even be low end warning snows.

I started a new thread for the Clippers this weekend...

The Clipper Train continues to flex it's muscles into this weekend. 2 shots at some decent snow events this coming Friday night into Saturday and another Clipper on it's heals poised to hit the region Sunday. Discuss...

We should start a new thread for the Friday/Sat Clipper and Sunday Clipper...

From Skilling's Blog: "The greatest purely lake-effect snowstorm in the Chicago area was December 19, 1973, when 5-12 inches of fluffy snow fell in the city, but 15-28 inches buried areas of Lake County, IL north to Green Bay." Maybe we can have something similar to this sometime this year with all the cold air we have been having and more to come. Just need a perfectly placed High Pressure and a storm system to our storm track to our south to produce NNE fetch down the lake.

CFS showing extreme cold Jan 26-31 period...

00z GGEM coming in juicy for the Sat Clipper and another one on its heels for Sunday. Some places in N IL/S WI may end up having 8-12" of snow by the end of this weekend with high snow ratios.
