Typhoon Tip Posted December 4, 2020 Author Share Posted December 4, 2020 11 minutes ago, OceanStWx said: I can actually see what the 3km has for a rime factor (which is incorporated into its snowfall) in AWIPS. So in general it can be more realistic than your traditional 10:1 or Kuchera maps because it's trying to model microphysics. The reason lift below the DGZ is not great as Will is pointing out here is because lift from below is likely driving supercooled water into the DGZ. If there is supercooled water hanging around you'll rime your snowflakes and kill your ratios. If lift is smack in the middle of the DGZ you can produce pure dendrites and don't have to worry about riming as much on the way down. I almost wonder ... Sometimes in thunder-snow ... you get these 'pingers' that aren't really clear like sleet, but are mangle aggregated refrozen thumpers along side of the "normal" aggregates. - Its something I routinely noticed when amid the fall column out of a snowing thunderstorm - I'm wondering if it's similar to what you are describing... to being 'in the top half of a CB cloud' ... interesting - like aggregates are getting UVM blasted and caked into clusters - hail seeds if you will... 2 1 Link to comment Share on other sites More sharing options...

In convection is most likely riming that is producing that, but in certain events actual sleet has been observed. OKX did in Feb 2013. Link to comment Share on other sites More sharing options...

Could be worse, there’s zero hope where I live. Nothing but growing puddles and cold wind. Link to comment Share on other sites More sharing options...

Kitzbuhel Craver Posted December 4, 2020 Share Posted December 4, 2020 Don’t mean to be redundant but, quite warm out there at the moment... We need to rip a chunk out of the stratosphere for this to work out like some think. 1 Link to comment Share on other sites More sharing options...

I wonder if it has to do with it being daytime and models want to naturally keep temps up or slightly rise? 1 Link to comment Share on other sites More sharing options...

However, what landed on my wool jacket was opaque and quite irregular in shape, obviously flakes very heavily rimed, or half-melted and refrozen. 12-18? I'll have to look at GYX's "90%/most likely/10%" table again. An hour ago it had Farmington at 0/10/11". 1 Link to comment Share on other sites More sharing options...

Warmer, pastier and less areal coverage version of 2003? Only a day early. (That beast dropped 24" of 14:1 pow with blizzard criteria for about 12 hours.)
