Hoosier Posted February 18, 2012 Share Posted February 18, 2012 12z NAM would be nice here if it wasn't trying to warm the surface to the upper 30s. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted February 18, 2012 Share Posted February 18, 2012 The Euro still appears to be the strongest with the piece of energy swinging through the area. Still a nice, but brief, band of snow from southeast Iowa to Chi/Mil. Link to comment Share on other sites More sharing options...

Hoosier Posted February 18, 2012 Share Posted February 18, 2012 Does anyone know how accurate those wunder maps are? It seems like they were too widespread with snow coverage when I looked at them a couple times before. Link to comment Share on other sites More sharing options...
snowstormcanuck Posted February 18, 2012 Share Posted February 18, 2012 Does anyone know how accurate those wunder maps are? It seems like they were too widespread with snow coverage when I looked at them a couple times before. I agree. They don't factor out non-accumulating WTSN. That's one of the problems I've found.

daddylonglegs Posted February 18, 2012 Share Posted February 18, 2012 Impressive. I'm not too pumped about this storm (or for that matter, any storm this year)...its just flipping back from all the previous winters with huge monster storms. This area, on average, just doesn't see foot+ snowfalls every year. Its pretty rare. I would be interested in seeing how common 6+ inch snowfalls are...I would guess we must avg about 1 per year...

Powerball Posted February 19, 2012 Share Posted February 19, 2012 GFS and GGEM look interesting. Maybe 1-3" Tuesday morning before changing over to a cold rain... It's still crap when all said and done. In any other winter season, this would be a decent winter storm for a lot of us. Link to comment Share on other sites More sharing options...

If there's a blizzard in the extended range, it will be crap. Don't count on anything except nothing! Link to comment Share on other sites More sharing options...
Geos Posted February 19, 2012 Share Posted February 19, 2012 Looks like the SREF, NAM, CMC, and EURO all has some type of snow event for far northern IL, central MI, and part of Wisconsin, maybe NE IA too. Link to comment Share on other sites More sharing options...

Thundersnow12 Posted February 20, 2012 Share Posted February 20, 2012 Just looking at the 0z NAM and its soundings, looks like a decent shot at a several hour period of fairly moderate snow across eastern IA/northern IL during the early morning hours tuesday. Wet bulb temps are still below 0 as precip moves in and with the good UVV's, could even cool the column a bit more to keep snow going till around 15zish. Evaporative cooling should also play a role at onset to favor all snow at the start. Right now I'd like cycloneville for a quick inch or two. After 15z or so the BL quickly warms and any leftover precip would switch over to rain. Link to comment Share on other sites More sharing options...
snowstormcanuck Posted February 20, 2012 Share Posted February 20, 2012 Given that the sfc low passes so far to the NW and the sfc winds are brisk from SW, I was surprised to see 0z NAM soundings supportive of snow for Tuesday. Even the RGEM ptype plots at least indicate a slushy mix. I guess it's keep an eye on worthy. Climo with these type of storms though doesn't have me too impressed.

Powerball Posted February 20, 2012 Share Posted February 20, 2012 Wow, GGEM does show a pretty decent 3 hour burst of snow for a lot of people with this. Even here, we're predomintately moderate snow before switching over to light rain/drizzle. Link to comment Share on other sites More sharing options...
Thundersnow12 Posted February 20, 2012 Share Posted February 20, 2012 FWIW the RPM model had 1-2" west of I-355 in northern IL, more as you go west. Link to comment Share on other sites More sharing options...

I caught the whole weather segment and Tom's cake at the end! That was cool! Looked like I-88/I-290 was the dividing line between rain and snow. NMM High resolution model is really generous with the moisture in the early morning. Link to comment Share on other sites More sharing options...
