WxUSAF Posted January 5, 2012 Share Posted January 5, 2012 Since this seems to be a widespread source of confusion...from an official meteorological reporting perspective, a trace of snow or rain is ONE observed snowflake/raindrop up to as many as can occur without .01" of liquid getting into the bucket or 0.1" of snow on the ground. You don't need a dusting or to be able to see it on the ground for a trace. Link to comment Share on other sites More sharing options...

You don't need a dusting or to be able to see it on the ground for a trace. I actually do know that, but since I would have been asleep for Schrödinger's snowflake, I would have needed something on the ground when I took the dog for a walk (6:00 am) to prove that I had actually received snow overnight. As such, no need to update my sig! Link to comment Share on other sites More sharing options...

Herb@MAWS Posted January 6, 2012 Share Posted January 6, 2012 Wow, congrats Bel Air. Trash can lid dusting here, nothing on ground. I am recording it as my 3rd "T" of this abomination of a snow season so far. A rhetorical question: How many "traces" = 0.01" ? Link to comment Share on other sites More sharing options...
Ellinwood Posted January 6, 2012 Share Posted January 6, 2012 Processed my sunrise pic from this morning (taken at 7:15am in Gaithersburg): We've been getting a lot of nice sunrises/sunsets this winter... it's been nice. Link to comment Share on other sites More sharing options...

WxUSAF Posted January 6, 2012 Share Posted January 6, 2012 Be careful...you're only 1 or 2 warmingista posts away from getting your snow weenie card revoked! Take heed! warmth consistently overperforms as well tho the cold shot was cold considering no snow cover anywhere Does it ever. Eh...it was chilly, but normally two days of ~-9 departures isn't exactly something to write home about. 5+ days of -9 departures is noteworthy. Just happens those were our first such departures since...October? September? Link to comment Share on other sites More sharing options...
