Dec 6-7th (It's not a clipper) Clipper

Earlier today, the CAMs were predicting a 6+" band along hw30 from central to eastern Iowa.  As the afternoon has progressed, these models have shifted northeast and dried out.  It looks more like 3-5 (hopefully still that much) across east-central Iowa.

Top down saturation complete.  Pixie dust has commenced here.

Summer is invading winter.  What happened to lake effect?

Part of the issue is that the water temps have come way down over the last month. As of a couple of days ago Lake Michigan water temps were just a smidge above average and dropping fast. Lake Huron was average but dropping fast and Erie and Ontario were both below average now. I know you only care about Lake Michigan but the way the water temps are dropping, it’s going to take a significantly cold airmass for heavy lake effect snow. Also there was 1.2% ice cover already too.

Where did CAD go all of a sudden?

[OrdIowPitMsp]

DAB+ here, 0.2” as of 6pm. Covers up the dirty snow at least.

I’ll take it

WHAT...SNOW EXPECTED. TOTAL SNOW ACCUMULATIONS RANGING FROM 2 TO 6   INCHES. THE HIGHEST AMOUNTS ARE EXPECTED IN THE VICINITY OF I-88.

Radar looks good 

[ChiTownSnow]

Seems to be progressing nicely.

[cyclone77]

A few tenths so far here after 2 hours.  Been extremely light so far, but better radar returns are incoming.

I have received 3 inches in a little over 3 hours.

It has begun. 

[cyclone77]

Took awhile but it's pouring pretty nicely now, smallish flakes.  Looks like a half inch or so.

Sleet/freezing rain/snow mixture here. Gunna b buried

Another inch in the last hour, now up to 4".

Saw that.  Gonna be a close call here, but thinking we should stay all snow.  

Flake size has increased finally with enhanced radar returns moving in now.  May really see it ramp up in intensity in the next hour or so.  Up to about an inch now.

If it stalls south of you, you are really going to see some good rates and big flakes from those nice reflectivities crossing the mixing line into the snow.
