>Good morning everyone. I did run the GFS again this morning just now, and I will tell you my findings.
We’re focusing in on the November 25th event first. So, the GFS is playing it out somewhat like this: Light to moderate snow. All precip in North Illinois ONLY, moderate-heavy snow in Wisconsin.
In future runs, this precip spreads in to Michigan.
Why am I mentioning this? Because the thickness is right and the cold front has already passed. This is a fine opportunity for snow to form.
Since the GFS has been hinting at precip for the last 3 days, I’m believing it more and more with each model run.
Alrighty. Moving on to our November 23rd event. If nothing comes out of it, this will be its final update.
The GFS would only display very light precipitation in North Illinois on November 22ND. ONE DAY EARLIER.
Anyways, That precip will be rain, because the thickness is above the maximum level needed for snow.
Conclusion: Light rain on Nov. 22nd, Sticking snow possible on Ill. Wis. borders, snowstorm possible in Wisconsin moving into Michigan.
