baroclinic_instability Posted December 9, 2012 Share Posted December 9, 2012 Snowier pattern foreseen for ANC anytime soon? We managed about 3-4" last night, I am not complaining. The pattern is definitely more favorable than what we had seen the last 1.5 months, but then, that isn't hard. Link to comment Share on other sites More sharing options...

baroclinic_instability Posted December 9, 2012 Share Posted December 9, 2012 Now that's how you break a bad streak. Quite an impressive overachiever up there. Interesting how this whole thing trended a bit south from a few days ago...which it seems we always assume the opposite will happen. Good stuff. Indeed, the southward shift was interesting. Worth noting not all cyclogenesis events end up farther W/NW. In this case the ejection point of the small scale tropopause undulation meant the difference. It is sometimes easy for us to think models can nail those things 3 days out, but those sub synoptic scale features are difficult for even the best models to handle.

baroclinic_instability Posted December 9, 2012 Share Posted December 9, 2012 Heavy snow here this morning and 23F, hopefully we get a couple inches to lock the coming inversion in place. I don't want my cold air escaping lol. The SLC/UT Valley inversions are prolly the most awful inversions I can think of. Nothing like pollution to ruin a nice new snowfall.
