A short forecast discussion for Western/Nortwestern WI

Will put the detailed forecast on hold until this evening.....For the most part snow still looks good,however with the latest computer model runs am going to cut snowfall amounts back down into a dusting to as much as an .050 in some areas..See forecast below for areas that may see that..Forcing does not look that great on the short term models as it did yesterday,also this system has little moisture to work with...Looks like the best and strongest forcing will remain over in MN ..Looks like a dry slot will build into my FA which will also keep snow totals down to a dusting maybe and 0.50 at best..Also the best moisture appears to say out over MN and avoids WI....So thinking is now..A dusting at best that is if we are lucky...Nevertheless most areas should see there first snowflakes of the season on Saturday
.Sunday night into Monday looks like a more of an interesting system...This could bring a better chance at accumulating snows from points around St.Cloud MN to Rice Lake,and Bruce WI.....While mixed rain and snow points South of that line.....If this system goes as planed we could be talking anywhere from 1 to 5 inches of snow..This system does have more going for it,however models are fighting with each other as to how the WAA sets up and where it sets up..This morning the NAM has the 540 line in my far Southern Counties GFS brings the 540 line more north into my Central parts of my central FA..So for now will run with my thinking above,however that may very well change.....We will really dig deeper into tonight...After that system the rest of the new work week looks murky as models are in argumentative mood with each other...So we will hold off on until Sat or even Sunday night to issue a forecast beyond Tuesday......
This whole forecast become one big headache for forecasters...
