hawkeye_wx Posted February 26, 2015 Share Posted February 26, 2015 My melted down rain gauge catch was 0.41, which means the ratio was garbage again. Because of the wind, 0.41 is probably low, too. The NWS keeps predicing ratios like 12, 15, 18, or even 20 to 1 for these cold storms, but it NEVER pans out. We definitely got a little more real fluffy snow this evening after I brought the gauge in and took a final measurement, so I'll likely have to add a bit.

I was thinking 15:1 shouldn't be a problem, even with potential for smaller flakes between better bands. I'm guessing LSRs here were right around 10:1 since flake size was pretty crappy even in the better bands. On the plus side the snow is fairly dense, and shouldn't settle at all over the next several days. Link to comment Share on other sites More sharing options...
Geos Posted February 26, 2015 Share Posted February 26, 2015 Up to 2.7" with more returns moving onshore. Link to comment Share on other sites More sharing options...
cyclone77 Posted February 26, 2015 Share Posted February 26, 2015 As is often the case this final band is comprised of fatty dendrites giving a nice snow globe action. Could fluff up quickly if band lasts long enough, but looks fairly transient. Nice to see some beefy flakes though, finally. Link to comment Share on other sites More sharing options...
RCNYILWX Posted February 26, 2015 Share Posted February 26, 2015 I wouldn't be too surprised if the midnight shift issues a Lake Effect Snow Advisory for Cook and NW Indiana given how impressive the snow bands have already been. Thermodynamics will improve overnight and 00z NAM and our local WRF-ARW only slowly pivot the low level lift and convergence eastward into the late morning and afternoon.

Sent from my SM-G900V Honestly I've been thinking advisory amounts for the lakeshore counties from the system/lake enhanced snow (less sure about the lake snow by itself). It's kinda muddled given the system snow and a lake effect snow advisory probably wouldn't have been the best headline to go with for tonight.

It's kinda muddled given the system snow and a lake effect snow advisory probably wouldn't have been the best headline to go with for tonight. I think had the decision been made earlier, WWA would have been way to go. But since no headline was put out and things are transitioning to pure lake effect, that was my main reasoning, and it seems based off the latest AFD, mid shift is leaning that way.
