The National Weather Service in Iowa must be tossing the Euro because parts of western iowa with no advisories.

I forgot what office mentioned it in their AFD, but the majority AFO’s are favoring the NAM as it’s historically better with these types of systems on predicting the WAA. Ultimately, they are expecting the warm air to push further north than what the other global guidance is showing.
 

All while my local office mentions this “low track is favorable for a classic CWA wide warning snowfall” :lol::rolleyes: (except for Calhoun & Jackson counties of course, but to hell with them, IWX or DTX can have them) lol.

Ratios will be everything with this system. Pretty impressive when it nearly doubles totals.
 

18z Euro 10:1 IMG_6667.thumb.jpeg.b92a6178aa711b6c77f06b0a1f2540cc.jpeg


vs. 18z Euro Kuchera Ratio (also note the higher totals for DTX on 10:1 vs Kuchera and the limited but notable lake enhancement from Milwaukee down to the southern ORD burbs.) Detroit concrete special incoming.

Lmao. What fools would pick the NAM. Especially when it's not fully sampled and the NAM injested bad data.

Same old frustrations with that office for Calhoun cnty :arrowhead:  Its only slighty less so for me up here. Their northern tier has a 6+ event and they can't produce a map, just a one line statement, lol.

Yeah, I wouldn’t make a map either. Contradicts their verbiage lol.

Well I hope this isn't a start of a trend of weaker and drier but would fit trends for this winter. How depressing. This looked solid for days. 

I wouldn’t put much stock into the NAM quite yet, especially with that disorganized look. Just doesn’t make sense, almost like it took in bad data.

The trend started about 12-18 hours ago

It's definitely odd but guess we will see what rest of 0z shows

I usually don't put much stock in 18z runs because no new data is input into model

I think that’s a thing of the past. Pretty sure 18z runs especially at this range are as good as anything. 
 

There’s no change for me to my call of 5-8” with locally 10” in best lake enhancement. You tend to see a drying trend especially with these less dynamic systems around 48-60 hours from an event. If you look to the east in northern Virginia and DCA, exactly this happened before gradually adding back some moisture in the past 12 hours.

Would be fitting for this winter. Thought we were finally going to catch a break. Apparently not. Watches will be getting downgraded to advisories if this continues.
