40/70 Benchmark Posted October 3, 2019 Author Share Posted October 3, 2019 I don't think speed of movement is that big of a deal. Its all about dynamics because most of the snow usually falls in a 6-12 hr window, anyway. How impactful if is that extra 6-12 hours of shreded returns? This is why we continue to get huge events amidst the compressed background flow. Now, if you want to argue that the fast flow will make phasing more difficult, maybe, but I don't think we are there yet. Link to comment Share on other sites More sharing options...

Kinda helped to screw up the winter on the east coast in general (with just mild to middling events at best). The heck has been causing this "fast flow"? Expand The fast flow can be a good thing or a bad thing in relation to track. It depends on the degree of phasing and percise location and overall speed of trough axis.

TalcottWx Posted October 3, 2019 Share Posted October 3, 2019 i think Dorchester sees 250" of snow this winter. Just my unbiased opinion. Link to comment Share on other sites More sharing options...
raindancewx Posted October 4, 2019 Share Posted October 4, 2019 I have a pretty snowy winter for the US generally this year. Our mountains here won't have snow on them from mid-October to mid-June like last year, but the mountains never really stopped dropping into the teens/20s this Summer here, there were frosts in populated towns in July on some nights. The entrenched night time dryness favors high snow ratios out here, even by mountain standards, even though the precipitation signal (for totals) isn't great. Ski visits and resort level snow were the best since 1997-98 out here, with 140-180% of normal values at that level, including early openings and late season extensions (Nov 16-Apr 10 or so, v. the more typical Nov 23-Apr 3). I have a sharp gradient between Northern Maine and Boston for anomalies this year, essentially the reverse of last year, with Boston seeing more relatively, and Maine seeing less relatively as you head North. US should be much drier than last year, but I think the storms that come through will often be extremely powerful. Something like +30% by Boston v. -30% by Caribou if I remember correctly, for snowfall. Link to comment Share on other sites More sharing options...

USCAPEWEATHERAF Posted October 4, 2019 Share Posted October 4, 2019 One huge impact factor for determining snowstorms of major magnitudes and snow that falls on the Cape and Islands is the Banana High Pressure, it is a real factor, more real than I imagined.
