dryslot Posted December 31, 2013 Share Posted December 31, 2013 No, its all how strong, and well alighned the lift is with the snowgrowth region....and how saturated the SG region is. Extremely cold, dry air masses can actually impede ratios in extreme instances. sugar Link to comment Share on other sites More sharing options...
40/70 Benchmark Posted December 31, 2013 Share Posted December 31, 2013 Right...and the long duration aspect might lead to 7-8 actual snow OTG, post-storm. Yup. Yawner in my book, but to each their own. Link to comment Share on other sites More sharing options...
ace0927 Posted December 31, 2013 Share Posted December 31, 2013 Ok, thanks. The post above seemed to imply that it did, that's all. Sorry for the confusion. that was my bad - didnt realize it ran the 0Z data Link to comment Share on other sites More sharing options...
40/70 Benchmark Posted December 31, 2013 Share Posted December 31, 2013 I think the most impressive, and memorable aspect of this whole event will be the thermometer readings as it transipres, when all is said and done. If you want to geek out, focus more on the thermometer, not the ruler. Link to comment Share on other sites More sharing options...

ctsnowstorm628 Posted December 31, 2013 Share Posted December 31, 2013 Going off the high ratio talk...it was 5F in VT for the 12/15 event and we saw 9" off 0.6" LWE...15:1 average which is slightly above the NNE average of 13:1. I'd say 13-17:1 is a decent first guess. Generally thinking 4-8" right now with more in SE MA. Temper expectations with this progressive flow. Banking on WAA and an inverted trough is not my cup of tea. Link to comment Share on other sites More sharing options...

40/70 Benchmark Posted December 31, 2013 Share Posted December 31, 2013 Guess I wasn't so crazy after all Are you referring to Forky's graph? "Snow ratio as a function of source layer temperature"...not 2m temp. Link to comment Share on other sites More sharing options...
Clinch Leatherwood Posted December 31, 2013 Share Posted December 31, 2013 Me neither. I think the extreme long duration nature has to do with the models trying to resolve the two surface "systems" and we'll see that condense a bit perhaps over the next 24 hours. But there should still be many OES posts....which I know you enjoy as much as PF upslope Link to comment Share on other sites More sharing options...
OceanStWx Posted December 31, 2013 Share Posted December 31, 2013 Guess I wasn't so crazy after all So much for a teachable moment. The source layer temp for BOS (most handy Bufkit I have right now) is -9 Thursday afternoon. That's all I'm saying. Not everybody knows that surface temps have nothing to do with snow ratio, I though some might like to hear the discussion. Seeing as it's not all that well received I'll refrain next time.

snowman21 Posted December 31, 2013 Share Posted December 31, 2013 Sorry, I thought people would see the map and think Boston CWA. I realized that after the fact and added the SLU disclaimer for clarification. And as I stated, I think we're primed for higher ratios too. I just don't think going wall to wall 20:1 is going to be the true outcome. What data is that based on? Just curious as to how it accounts for measurement issues both in terms of snowfall and gauge undercatch which would tend to inflate ratios.

It's the best measurement we have, gauge undercatch and compaction are a part of snowfall whether we like it or not. Link to comment Share on other sites More sharing options...

OceanStWx Posted December 31, 2013 Share Posted December 31, 2013 Is clearing every 6 hours considered inflating? According to the latest guidance, it sounds like it is considered unnecessary not inflating. I think because most Coops only measure once per day they are asking all snow measurement to work that way. But I didn't see anything that asks you to stop doing 6 hourly (or only 4 times or less per 24 hours). Because our paid observers at major airports still do 6 hourly.

powderfreak Posted December 31, 2013 Share Posted December 31, 2013 Not in BOS, but ORH and BDL with temps near 0 would be close Surface temps have nothing to do with it...in fact I often see ratios tank once you get below 10 degrees at the SFC. And you can get great ratios at 32 degrees. It's all mid level snow growth temps. And ratios are derived from the flake type in that area. Link to comment Share on other sites More sharing options...
