tuanis Posted November 20, 2015 Share Posted November 20, 2015 Weird sucker hole around JOT. Maybe caused by already marginal temps ticking up a degree or two due to warm lake influence, thus limiting accums? Link to comment Share on other sites More sharing options...
DaveNay Posted November 20, 2015 Share Posted November 20, 2015 No real accumulation to speak of, but the minimal amount of flakes which have fallen so far have not melted. Looking like sugar is spilled all over the driveway, just enough to sparkle in the streetlight. No rain or ground temp issues here. Still nothing 4 miles south Link to comment Share on other sites More sharing options...

I don't know, it's sort of a weird look for it to be lake influence. It could be a relative min in qpf in that area, but would have to check.

mimillman Posted November 20, 2015 Share Posted November 20, 2015 FWIW, HRRR had this starting as rain in most of LOT cwa. At least on the precip maps that is. Link to comment Share on other sites More sharing options...
kevlon62 Posted November 20, 2015 Share Posted November 20, 2015 Went from a few stray flurries to light snow in the last five minutes in Crystal Lake. Link to comment Share on other sites More sharing options...
michsnowfreak Posted November 20, 2015 Share Posted November 20, 2015 Interesting to note that all of the 18z models ticked SE. In fact, the GFS and RGEM not only keep us all snow, but sets the initial frontogenesis band overhead (versus NW of here). I will take the 18z gfs and RUN! Solid 1" QPF for DTW and All snow.

SchaumburgStormer Posted November 20, 2015 Share Posted November 20, 2015 Still nothing 4 miles south I can confirm the snow stops about 2 miles south of me. Headed south to Decatur for the weekend and drove right out of the flurries. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted November 20, 2015 Share Posted November 20, 2015 For whatever reason, a band of dry air is stuck over east-central Iowa and it's killing us. Heavy snow had no problem spreading eastward to the north and northeast from Waterloo to Dubuque into northern Illinois, where widespread 2-3 inches has already fallen, but here in Cedar Rapids we got a quick burst a couple hours ago and then it just stopped and hasn't started up again.

Powerball Posted November 20, 2015 Share Posted November 20, 2015 I will take the 18z gfs and RUN! Solid 1" QPF for DTW and All snow. Even the 18z NAM verbatim was all snow (granted just barely). Only the areas below 950mb were above freezing, and that's by less than 1*C. Link to comment Share on other sites More sharing options...

That's because the main FGEN axis was to your north, leading to faster saturation. That was always supposed to be the case. Link to comment Share on other sites More sharing options...

The initial round of snow may melt during dryslot before main storm hits Well even then, if that main round comes roaring in with 1-2" per hour rates and muffin-sized flakes for 2-3 hours (very much plausible based on the progged Omega values in the DGZ and the increasing instability shown), that lull may ultimately be a non-factor. This is all assuming we stay all snow and we do experience a lull of course. Link to comment Share on other sites More sharing options...

cyclone77 Posted November 20, 2015 Share Posted November 20, 2015 Top down sat underway. Should be snowing in another hour or so. Once it starts it's gonna pick up quickly. Point has 8"/2" tonight/tomorrow for 10" total, with 8-12 in the zone for the county. Sounds about right. I gotta drive in this early tomorrow morning around 6am. Should be an interesting drive lol.

ilstormchaser Posted November 20, 2015 Share Posted November 20, 2015 Rap is ticking the heavy snow band slowly Southward for the Peoria area. It will be interesting to see if this trend continues. If it actually continues this trend and the 0z models are showing it, ILX may have to upgrade to a warning for their Northwest and far Northern counties.

wxman1952 Posted November 20, 2015 Share Posted November 20, 2015 I'm north of the heavier projected snowfall area for lower MI, but I'd rather be north than south incase of a north jog in the storm track. Happy storm watching everyone Link to comment Share on other sites More sharing options...
