T. August Posted March 4, 2015 Share Posted March 4, 2015 winterymix, that's snow depth. Try using "Sfc Snowfall". It's much better and more accurate. Link to comment Share on other sites More sharing options...

Angela T Posted March 4, 2015 Share Posted March 4, 2015 I am thinking this is not the high res 4k nam though. I would like to wait and see what it shows. Link to comment Share on other sites More sharing options...
MN Transplant Posted March 4, 2015 Share Posted March 4, 2015 Lol...gee whiz nam! Zero consistency I wouldn't say that necessarily. It is just that a very subtle shift for us means a huge difference. Which seems to be a case for us a lot, of course. Link to comment Share on other sites More sharing options...
Random Chaos Posted March 4, 2015 Share Posted March 4, 2015 12hr QPF at 45hrs (covering the entire sleet + snow period through then) is at 0.8 to 1.0" on NAM. Just needs to be colder at the start! Edit - adding image: Link to comment Share on other sites More sharing options...

Ravens94 Posted March 4, 2015 Share Posted March 4, 2015 By 12z tomorrow the NAM should be where other guidance is. moving south run after run. what a crappy model. GFS will probably wreck everyone. Link to comment Share on other sites More sharing options...

SLPressure Posted March 4, 2015 Share Posted March 4, 2015 Yeah, NAM not too bad actually. But again..NAM. Definitely backing down to the globals, little by little Yes. But it is showing the later onset of the heavier QPF. When the column is cold, we get the rates. Let's see the continuation with the rest of the 00z suite. Looking like Thursday day time as opposed to Thursday pre-dawn and AM. I just hope it all works out in our favor. Link to comment Share on other sites More sharing options...
