Hoosier Posted February 7, 2023 Share Posted February 7, 2023 Plenty of confidence now in a dynamically cooled setup allowing for a decent band of snow accumulations, as a negatively tilted shortwave moves through the area with fairly rapid surface low deepening (bombogenesis-like?). The main snow band looks to avoid the vast majority of posters here, but at least some will get in on it. With that being the case, I figured we could make this one an all-emcompassing thread as some decent rains look to occur on the warm side, along with a period of gusty winds given the robust deepening and relatively quick movement through the region. 2 Link to comment Share on other sites More sharing options...

Looks like the CR crew could cash in if things go perfectly. May see the grassy surfaces dust up some here in the QCA for a time Thu. Prob enough to bump MLI over the all-time futility mark unfortunately. Link to comment Share on other sites More sharing options...

hawkeye_wx Posted February 7, 2023 Share Posted February 7, 2023 The 00z Euro did become stronger and snowier compared to the 12z run. Of course, this will be very wet, low-ratio snow, and if the Euro is too cold by a degree this forecast will bust. This is the snowiest of all the models this evening. I would err on the low side. DVN, this afternoon, said not much snow south of Waterloo-Dubuque. That's certainly possible. I can't help but get a bit angry because we finally get a rare, strengthening low, loaded with moisture, tracking from St. Louis to Chicago (maybe once every few years track) and there is no f'ing cold air.... in early February. 19 times out of 20 this is a big snowstorm. 2 Link to comment Share on other sites More sharing options...
Hoosier Posted February 7, 2023 Author Share Posted February 7, 2023 As far as the wind, there is a zone of 925 mb winds of 50 to possibly 55 kts on Thursday. Assuming the system deepens about as progged, it should lead to a solid wind advisory event with some areas possibly approaching high wind warning criteria.

It should be noted that the Euro has >12" of snow for Marquette and Green Lake Counties, WI inside of 72 hours...and there are currently NO winter weather headlines in effect for those counties. 1 Link to comment Share on other sites More sharing options...

madwx Posted February 7, 2023 Share Posted February 7, 2023 This is a perfect storm to use positive snow depth change model outputs.

hawkeye_wx Posted February 7, 2023 Share Posted February 7, 2023 12z Euro is super juiced, with a very heavy burst of snow Thursday morning. Other models show considerably less precip and snow. I'm still thinking 3" of snow in my yard, at most. This stuff will be concrete. DVN is thinking a 4-6:1 ratio. 2 Link to comment Share on other sites More sharing options...
Hoosier Posted February 7, 2023 Author Share Posted February 7, 2023 12z Euro would certainly support a potential window of high wind warning criteria winds in parts of the LOT cwa (especially southeast 1/3 or so) and much of the IWX cwa. Link to comment Share on other sites More sharing options...

cyclone77 Posted February 7, 2023 Share Posted February 7, 2023 Looks like a solid rainer for the QC, probably 1-1.5". Think we'll see a burst of snow at the end Thu but good chance it's not measurable. Link to comment Share on other sites More sharing options...

The HRRR has always been on the east edge and hasn't budged. The western part of the watch area in Iowa is being deserted by the models. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted February 8, 2023 Share Posted February 8, 2023 Man, another system, more model frustration. Tonight, half the models show little, if any, precip in much of the Iowa winter storm watch that was just issued this afternoon. The GFS still hits my area hard, but other models are east and weak with the backside precip. I don't know what the NWS is going to do with the forecast.

I'd guess 3-5" in the main swath with isolated higher amounts. You guys are probably gonna be pretty much in that. I'd put the spine of the band from Oskaloosa up to about Prairie du Chien. Looks like the best chance at 5+ will be further north towards Prairie du Chien and into southwest WI where the storm maxes out. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted February 8, 2023 Share Posted February 8, 2023 The Euro has been the most bullish model with both total precip and snow in Iowa. Tonight's run pulled the rug out, cutting everything by at least half. I'm really getting tired of being teased by models this winter. 1 1 Link to comment Share on other sites More sharing options...

Nelson Posted February 8, 2023 Share Posted February 8, 2023 Liking 4-5" for the Madison area crew. Already been mentioned but too bad there isn't some colder air around. Moisture feed looks nice. 1 Link to comment Share on other sites More sharing options...
