NEJeremy Posted December 9, 2016 Report Share Posted December 9, 2016 GFS screws us so hard. And it's been consistent today so I think we're done for. *slow claps for Chicago*on to the next storm around the 17th. Although, today the runs got rid of the storm around the 17th for Nebraska. I'm saying we stay under 6" total here in December Quote Link to comment Share on other sites More sharing options...
ToastedRavs Posted December 9, 2016 Report Share Posted December 9, 2016 Looks to be trending a little south each run Ever so slightly, I agree. But, also dragging in some warmer air too each run. That R/S line creeps into S. IA and even somewhat close to Chicago. Even if some don't switch over, that's going to bring the snow ratios closer to 10:1, a wetter snow cutting back on totals.

WBadgersW Posted December 9, 2016 Report Share Posted December 9, 2016 Nice 1-1.5" increase on the GFS. Up to 11" Hopefully things get ironed out tomorrow. Still lots of different scenarios. Quote Link to comment Share on other sites More sharing options...

Stormgeek Posted December 9, 2016 Report Share Posted December 9, 2016 Not sure what the GFS was smoking on the 00z. I don't think there is any way MSP gets that ongoing band at the end of the event. As much as I want it, I don't think 6 inches is doable, assuming no other shifts/changes as the energy comes on shore. Quote Link to comment Share on other sites More sharing options...

East Dubzz Posted December 9, 2016 Report Share Posted December 9, 2016 Some of the people around me (including me hometown) will be pleased with that run of the NAM, but I think a lot of us are going to want to pretend that run just didn't happen.

Tom Posted December 9, 2016 Author Report Share Posted December 9, 2016 RPM model shifted south with the 1st wave and looks to lay down a solid 3-5" through 6:00am Sunday for N IL. Looks sorta similar to the NAM as I wonder if the northern stream becomes the dominant one.Here is LOT's take.. http://www.weather.gov/images/lot/WxStory/FileL.png?rand=24680 Quote Link to comment Share on other sites More sharing options...
Tom Posted December 9, 2016 Author Report Share Posted December 9, 2016 I'd imagine NWS offices to issue WSW's after the 12z suite of runs if trends continue. Excited to see another snowstorm over the weekend. Although, holiday shoppers are not going to like it as well as retailers. LOT saying the snow ratios should be around 17:1 with the 1st wave. Should be some nice fat/fluffy flakes falling outta the sky! Quote Link to comment Share on other sites More sharing options...

CentralNebWeather Posted December 9, 2016 Report Share Posted December 9, 2016 0z NAM looked good for some in Nebraska for the 2nd wave, now 06z nothing. Hopefully it comes back at the 12z but not holding my breath. NWS Hastings even mentioned this during their morning discussion and how they don't trust models that are this changeable so for now dry forecast. NWS Hastings "The12z/18z/00z NAM runs each bring a swath of 1-4" into parts of thefcst area...but the 06z came in dry." Quote Link to comment Share on other sites More sharing options...
Tom Posted December 9, 2016 Author Report Share Posted December 9, 2016 RPM model had a pocket of 10"+ for the northern counties of N IL and just south of Madison for the southern tier of counties near the IL border. Solid 6-10" for N IL/S WI/N IA from what I could tell. Quote Link to comment Share on other sites More sharing options...
