About an inch so far. There seems to be a touch more moisture than forecast (doesn't take much with these temps) and the subtle forcing seems to be hanging around longer than forecast. Returns to the west looking decent so maybe add another inch or 2 by morning if we're really lucky. Keep the Swoop McClain ripples coming That's an inside comment that most here won't understand. Woke up to quarters gently falling from the sky. 1 1 Link to comment Share on other sites More sharing options...
Chicago WX Posted February 8, 2021 Share Posted February 8, 2021 I core sampled that 2.2" of snow. 0.05" liquid. So yeah...40:1. Still rocking cotton balls here... 8 Link to comment Share on other sites More sharing options...
RCNYILWX Posted February 8, 2021 Share Posted February 8, 2021 I core sampled that 2.2" of snow. 0.05" liquid. So yeah...40:1. Still rocking cotton balls here...Just called in your report to the office. Nice dendies here but only a dusting since we spent much of the night north of the band. The ultra high ratios you got might bode well for later. Sent from my SM-G965U using Tapatalk 3 Link to comment Share on other sites More sharing options...
OrdIowPitMsp Posted February 8, 2021 Share Posted February 8, 2021 Wound up with .2-.3” of new snow on just a trace of precip. NWS only mentioned a slight chance of flurries in the aviation discussion. Impressive what moisture can be squeezed out of this airmass. 1 Link to comment Share on other sites More sharing options...

purduewx80 Posted February 8, 2021 Share Posted February 8, 2021 Later this afternoon doesn't look too bad near and north of 290/88 up to the WI border, as long as moisture isn't an issue. Best frontogenesis-produced lift in the DGZ focuses in these areas for several hours. There is good right entrance region jet dynamics helping this along. Could be some of those 30:1+ ratios where the banding sets up. 4 1 Link to comment Share on other sites More sharing options...

janetjanet998 Posted February 8, 2021 Share Posted February 8, 2021 looks like around 2 inches of pure fluff on the north side of PIA if a bird farts there will be a blizzard so it may get interesting later in the week even with a moderate strength system with any wind 4 Link to comment Share on other sites More sharing options...

NEILwxbo Posted February 8, 2021 Share Posted February 8, 2021 Last night overperformed further south so hoping today’s wave will have the same effect further north. Should be a fun day either way with fat flakes already falling Link to comment Share on other sites More sharing options...
sbnwx85 Posted February 8, 2021 Share Posted February 8, 2021 I thought we were getting a surprise lake effect band before looking at radar. Hard to tell how much has fallen with what was already on the ground but I can tell the ratios are phenomenal. Might be closing in on an inch? The best banding looks like it was just to my south.

Ha. Easily 2in. Maybe a bit more. GFS seems to want to really push the storm track way south after mid week which is possible but other models are more generous bringing snow pretty north into IL. Nice band coming together across eastern Iowa and Western IL. Link to comment Share on other sites More sharing options...
McHenrySnow Posted February 8, 2021 Share Posted February 8, 2021 Just up here waiting impatiently, but happy to hear about the ratios. HRRR and RAP give me reason to be optimistic I can get at least an inch this afternoon. Temp is up to a balmy 8º. Link to comment Share on other sites More sharing options...
WeatherMonger Posted February 8, 2021 Share Posted February 8, 2021 ILX late morning update .UPDATE... Issued at 1036 AM CST Mon Feb 8 2021 Increased PoPs in the western third of CWA over the next few hours as snow moves in. The current forecast snow/liquid ratios of 19:1 in the northern part of our CWA may be too low, as precip reports from last night`s snow indicate snow/liquid ratios of 25:1 or greater. May increase the ratios, especially over the northern half of the CWA, resulting in incrementally higher snow totals, but that won`t change the thinking that a broad 1" of fluffy snow occurs with this system, with 1-2" south of the I-70 corridor where higher QPF is expected. Monitoring our far southeastern counties for the potential of light freezing drizzle around midnight this evening. No changes to the forecast yet, but model sounding suggest profiles may lose ice crystals around that time. However, ascent will be very weak, reducing confidence in the likelihood of any freezing drizzle occuring Link to comment Share on other sites More sharing options...
purduewx80 Posted February 8, 2021 Share Posted February 8, 2021 Lake effect is very close to the Chicago shore this morning. Some of the guidance yesterday suggested it could come into downtown w/ the synoptic snow this afternoon/eve, but it looks like there may end up being a mesolow that keeps it just offshore. Close call though. Cedar Rapids to metro Chicago should be in good shape for 2-4". Wouldn't doubt if there are some locations that pick up more than that looking at radar trends and obs in Iowa. 2 Link to comment Share on other sites More sharing options...

janetjanet998 Posted February 8, 2021 Share Posted February 8, 2021 REA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 1110 AM CST MON FEB 8 2021 UPDATE ISSUED AT 1105 AM CST MON FEB 8 2021 NARROW BAND OF STRONGER FORCING IS PRODUCING RESPECTABLE SNOW ACROSS CENTRAL IOWA WHICH IS DEVELOPING/MOVING RAPIDLY INTO EASTERN IOWA. VERY SHORT TERM GUIDANCE IS NOT HANDLING THIS WELL BUT GIVEN ARCTIC AIR IN PLACE HAVE ISSUED A WINTER WEATHER ADVISORY FOR THE I-80 CORRIDOR TO SOUTH OF HIGHWAY 20. THE OVERNIGHT SNOW HAD SLRS OF 25-30:1 WHICH PRODUCED AREAS OF 2-3 INCHES OF SNOW. THE SAME HIGH RATIOS SHOULD BE IN PLAY WITH THIS BAND OF STRONG FORCING. THUS EXPECT A SWATH OF 1-2 INCH SNOWFALL WITH A BAND OF 3 INCHES. Link to comment Share on other sites More sharing options...

cyclone77 Posted February 8, 2021 Share Posted February 8, 2021 Snow globe-ing here quite nicely as the enhanced band has arrived. Sure nice to see after the pixie fest on Sat lol. Looks like 2"+ of arctic fluff to fall. 3 Link to comment Share on other sites More sharing options...
purduewx80 Posted February 8, 2021 Share Posted February 8, 2021 this is where old-school meteorology gave us some clues for today. not too surprising that fgen forcing is more intense than modeled given this jet streak passing by (it gradually lifts NE from where it's shown below). shame it won't be in place longer than a few hours. That said, there is focus at 700mb through the night, so light snow may end up persisting all the way into tomorrow morning in the general areas its occurring now. 3 Link to comment Share on other sites More sharing options...
janetjanet998 Posted February 8, 2021 Share Posted February 8, 2021 either models are slow with developing the snow band (had nothing now) or they are completely missing it this morning so the question is are models just too slow with the system and the snow band developed faster and will move out faster resulting in the same amount of snow OR is this bonus snow that the models missed this morning and no change with the afternoon and overnight timing? 1 Link to comment Share on other sites More sharing options...
