  1. A lot of people confuse true DD with very light snow. It can get tricky in the mountains too because at cold temps even with weak lift you can squeeze out some snowflakes even with barely the hint of a cloud. But DD is simply ice fog. I think the Inuit term for it was pogonip. But as you know it’s difficult to freeze tiny water droplets because of their curvature. You need really cold temps to get them to spontaneously freeze. That’s why it’s usually around -30 or colder and in valleys so it can saturate and go immediately to ice form instead of supercooled droplets.
  2. I like big cold…I just worry about my birds and plants. There’s just something about going out in a calm -20° or colder airmass and breathing it in. 0°F is cold, but when you push -30 it’s on another level.
  3. I don’t think anyone had DD from that airmass in SNE. Wasn’t it really windy? I remember ORH doing -10° or something in that. DD is basically the frozen form of fog…a cirrus cloud at the sfc.
  4. That was more of a shallow cold. 850s were relatively warm. 04 had -25C 850s in S NH with snowfall.
  5. Heh. That reminds me of 1/14-15 2004 where we had a synoptic snowfall a few degrees below 0F. Yakutsk dropped in behind it.
  6. We’re trying to get @radarmanpond hockey tournaments into May
  7. Yeah let’s get those airmasses inside d7 without a moderating trend. But yeah, looks cold overall and potentially active either way. Although the 6z goofus had some creative ways to screw AEMATT despite cold and high QPF.
  8. Op/details/6z gfs aside… That was kind of a fun run to loop through seeing those massive, sprawling 1040+ highs sandwiched around shortwaves trying to barge through the cold. @WxWatcher007 would get his -35° at SLK under one of those highs.
  9. Wow. You only got down to 38°? Let’s get those forsythia buds swelling.
  10. Yeah I think we’re going to get some action in the extended as well.
  11. Sometimes I wish everything goes black and winter ends.
  12. Cold cut pattern sounds like it should be a meme here
  13. Whatever. It was in jest anyway. But like Will said, can’t totally rule it out.
