cyclone77 Posted January 5, 2015 Share Posted January 5, 2015 Pouring tiny flakes here. Probably a few tenths or so. Gonna bump from 4-6 down to 3-5". May end up on the low end of that unless flake size can pick up. Link to comment Share on other sites More sharing options...

cyclone77 Posted January 6, 2015 Share Posted January 6, 2015 One thing's for sure, anything <20DBZ produces flakes about the size of a gnat. Need to get into the heavier bands to get bigger flake size I'm guessing. Not even a half inch yet here. Link to comment Share on other sites More sharing options...

Thundersnow12 Posted January 6, 2015 Author Share Posted January 6, 2015 Ah that was fast. Didn't think to look yet. Too cold closer to the sfc but fairly nice DGZ between 800mb-900mb and then another one above that warm layer. Link to comment Share on other sites More sharing options...
The_Global_Warmer Posted January 6, 2015 Share Posted January 6, 2015 Maybe the winds are crushing the flakes. Link to comment Share on other sites More sharing options...
extremewx52 Posted January 6, 2015 Share Posted January 6, 2015 Also,a majority of the lift is actually at the top of the DGZ and above. Would like to see the best lift focused within the DGZ. This may also be contributing to the lower ratios. Link to comment Share on other sites More sharing options...

Jonbo Posted January 6, 2015 Share Posted January 6, 2015 So far the Des Moines metro area has had the highest snowfall reports (as of 6:35pm). Hopefully these amounts can (try to) continue down into SE Iowa and east. Link to comment Share on other sites More sharing options...
