I went back through model runs in the 48 hour leadup and compared to the obs map above. Thought this was a clear NAM winner. Feel like it's had a good season. Very clear banding signatures that happened. Euro was good too. The old EE rule and ignoring all the other model noise would have given us the best handle of this particular storm. Most guidance wanted to jackpot southeast MA, but between mid-level processes generating bands further northwest and initial boundary layer issues southeast, jackpot ended up in the 495 corridor and extended further north than most expected. RGEM was spastic and more wrong than right. GFS was a national embarrassment, pretty much ignorable. Ok with SLP track, but qpf depictions and thermals were a joke.

JC-CT Posted March 15, 2018 Share Posted March 15, 2018 BOX stole Ray's snow. I bet they didn't have him in a warning! 1 Link to comment Share on other sites More sharing options...
powderfreak Posted March 15, 2018 Share Posted March 15, 2018 Another 3-4" at home last night (call it 3.5") and 7" at 1,500ft with 10" at 3,000ft. Totals currently around 18" at 750ft, 25" at 1,500ft and 32" at 3,000ft and still snowing hard up here. With various upslope and synoptic storms, there's been 58" at the mountain in the past 8 days. It looks obscene up here this morning. Grooming reporting fresh drifts over 5 feet overnight. They are going up to extricate a stuck snowcat too. When those things get stuck you know its getting deep. 2 Link to comment Share on other sites More sharing options...

However, during the event, I disagree (if perhaps this is a strawman argument) that 6-hour clear should be done, because as I was just describing, storm circumstancial melting/settling/or even sublimation - though that would rarefied, should be considered part of the event. Strongly agree with this but folks just go on and on and on measuring all the time..... Link to comment Share on other sites More sharing options...

tamarack Posted March 15, 2018 Share Posted March 15, 2018 14 hours ago, rgwp96 said: No it came from your old area fayson lakes . I believe the actual road was cliff trail Cliff gets up to about 870', highest point in Fayson Lakes. If there was any elevational advantage for that storm, Cliff Trail would be the place. The moist and dense 2.5" of snow during the day yesterday settled the overall depth to 3" less than I'd seen earlier at 7 AM. 34" is still a nice pack for mid March - I think this Saturday we strap on the snowshoes and prune apple trees.

powderfreak Posted March 15, 2018 Share Posted March 15, 2018 This is no upslope fluff anymore like yesterday. This is a dense 10". Had to be .75-1" QPF. Surf on top of it not in it. I saw JSpin had under 10:1 ratios so that makes sense. Link to comment Share on other sites More sharing options...

I agree with ctvalley the 2.9 might be a bit low in this area although downtown would not surprise me....4 to 5 will do it the upslope is astonishing and the retention once above 800-1k this time of year too Link to comment Share on other sites More sharing options...

I just built myself a whiteboard. It is slightly elevated off the ground by a couple long legs made from something similar but smaller than a 2x4 flipped tall side vertical. It does seem to make a difference vs the top of my black impreza. Next step will be to get some powered refrigeration under that baby just like an ice rink lol Link to comment Share on other sites More sharing options...

Isn't that the point of making it 6hrs? To allow for some compaction? I've said it before, but I don't like penalizing 1"+/hr rates on the tail end of large, long duration storms. In LES land...if you pull 20" in 12hrs, clear, and then another 20" in 12hrs, but the depth only increases another 6"....does that mean you should have 40" or 26"? If both 12hr samples had the same rates with the same amount is it fair to report it as 20" for the first 12hrs and only 6" for the last 12hr?

If both 12hr samples had the same rates with the same amount is it fair to report it as 20" for the first 12hrs and only 6" for the last 12hr? Tip is right about one thing, measuring as close to the end of the snowfall as possible is ideal (and recommended by the way). But if you think about this all in an impact sense, what makes more sense: plows waiting until the snow stops and removing snow, or plows nearly continuously keeping roads clear? I would argue a plow operator is much closer to observing the 6 hourly snowfall amounts than the 24 hourly. It's one thing we've discussed internally about the 6" in 12 hours vs 9" in 24 hours warning criteria. If anything the lighter, longer duration 9" in 24 hours is more impactful because road crews are out longer. 1 Link to comment Share on other sites More sharing options...

Not a whiteboard, but I had other flat surfaces to ensure that that depth was representative, which it was and always is. Very protected area...depth was a pretty uniform 24"+.

powderfreak Posted March 15, 2018 Share Posted March 15, 2018 Every time you think it's going to stop it seems to pick back up again. Just snowing moderate snow all morning but with wind visibility is under 1/4 at times. Very windy too. Been snowing for over 48 hours straight at this point. 2 Link to comment Share on other sites More sharing options...
