But I'm not really seeing this in models HRRR/RAP show this...but doesn't appear to hinder snowfall accumulations much. Link to comment Share on other sites More sharing options...

Robust This would be the only way the immediate lakeshore turns over to snow early, if the system wraps up stronger than expected. 2 Link to comment Share on other sites More sharing options...
Stebo Posted October 31, 2019 Share Posted October 31, 2019 Part of the reason why the city stays warmer through the day on the GFS is the TROWAL noses in and keeps them above freezing at surface to 925mb until 21z even near 0 at 850mb. Link to comment Share on other sites More sharing options...

hawkeye_wx Posted October 31, 2019 Share Posted October 31, 2019 Our temp has fallen to 29º, so the snow is now accumulating on the pavement. 1.5-2.0" has fallen in the CR area. This morning, it had looked like 1.5-2.0" would be our total, but some decent bands got going early. The snow should continue to pivot through the area all night. 1 Link to comment Share on other sites More sharing options...

Snow is beginning to stick to paved areas here as well, as we've dropped to 30. Closing in on an inch on non-paved areas. Flakes are larger now. The first 4hrs had very fine flakes.

hlcater Posted October 31, 2019 Share Posted October 31, 2019 2.3” measured just a few minutes ago. Snow is coming down at a moderate but sufficient clip. We will oberperform model forecasts if this keeps up. 3” looks like a lock and 4” might be attainable. 3 Link to comment Share on other sites More sharing options...
CoalCityWxMan Posted October 31, 2019 Share Posted October 31, 2019 Already starting to stick to all surfaces now. Ripping out there 1 Link to comment Share on other sites More sharing options...
cyclone77 Posted October 31, 2019 Share Posted October 31, 2019 A little under 1.5" so far. The accumulation rates have been very slow all evening. Mostly due to very small flake size for 4hrs, and the showery nature of the better rates. Kind of typical for a long-duration event. Still another 10-12hrs of steady snows to go, so 4-5" still looking good. Rates should get better later on when the showery stuff pushes east, and we get more into the deformation zone. 2 Link to comment Share on other sites More sharing options...
Hoosier Posted October 31, 2019 Author Share Posted October 31, 2019 PIA is reporting freezing rain. I wonder how many times that has happened before November. 1 Link to comment Share on other sites More sharing options...
Hoosier Posted October 31, 2019 Author Share Posted October 31, 2019 It looks like area to watch for maximum tree impact is a zone just inland to the west of Lake Michigan... possibly including ORD area. That area sort of combines the factors the best -- winds a bit stronger than areas farther west and temps not dropping below freezing as quickly.

A-L-E-K Posted October 31, 2019 Share Posted October 31, 2019 Today looks like a rainer/white rainer imby with a 1-2 hr window of rip city on the back end with the lake enhanced defo. DAB+ to 2 was a good call here and see no reason to change. Office should manage 3-5 and commute to ge home and go trick or treating gonna be a challenge later 2 Link to comment Share on other sites More sharing options...

cyclone77 Posted October 31, 2019 Share Posted October 31, 2019 3.0" here and still snowing nicely, with a nice enhanced band about to move in from the west. Should have no problem clearing the 4" mark. The snow pack is pretty dense due to the wet nature, and the smaller flakes much of the event. 2 Link to comment Share on other sites More sharing options...
