Puns aside, I'm not always a fan of highly anomalous features trying to deliver. Potential to squash a storm event in increases.

bwt3650 Posted November 27 Share Posted November 27 It is so refreshing to see this look coming up in December. Even if we somehow don't get much, just nice to see the ridge out west.

These last two winters were extremely harsh on my attitude, but hopefully we can cash in. Next thing to work on for the surface, are Scooter highs...but that is more in the 1-5 day period. 1 Link to comment Share on other sites More sharing options...

No. Some snow accumulation maps accurately convert modeled liquid precipitation to snow at a 10:1 ratio. StormVistaWx does not. So it's in a different category altogether from other so called clown maps. Hopefully this is understood when people consider what they would take in terms of fantasy snowfall. 1 Link to comment Share on other sites More sharing options...

This is a relatively simple and hopefully non-controversial point. Link to comment Share on other sites More sharing options...

I don’t take them seriously either way. So it’s not really an interesting detail to parse to me. But I’ve def heard the SV maps have a reputation for being overdone. But then again, 10 to 1 is often overdone for various reasons too whether models overdo QPF or snow growth is bad or temps are marginal. Sometimes they’re underdone on occasion when snow growth is good. Link to comment Share on other sites More sharing options...

This is a relatively simple and hopefully non-controversial point. Which is dumb, that's not how snowfall or accumulations work. Snowgrowth and cloud processes are extremely important as is the degree of lift into the snowgrowth zone, wind, type of snowflakes (well that goes with snowgrowth) and thermal profile. These factor greatly into the snowfall ratio which also isn't a constant throughout the storm, the snowfall ratio is going to vary and sometimes greatly. You can't just assume ptype and multiply by 10 and none of these fancy algorithms factor in what's most important. Link to comment Share on other sites More sharing options...

Whether a 10-1 ratio is correct is irrelevant to the point. When a snow map shows "total snowfall at 10:1", the primary model parameter in question is QPF, not accumulated snow. The secondary model parameter, which is often calculated by 3rd party algorithm, is ptype. If a model correctly predicts QPF and ptype, a snowfall map that multiplies liquid equivalent by 10 and displays it as total snowfall at 10:1 would be absolutely correct. It just might not be an accurate prediction. Some 3rd party maps do this task pretty well. StormVista does not. Link to comment Share on other sites More sharing options...

Sometimes they’re underdone on occasion when snow growth is good. A factor of 2 is a big difference IMO when people still post SV maps on this board and then you start referencing those maps. Go check how StormVista compares to Pivotal or TropicalTidbits or whatever others are out there in terms of snowfall. Yes 10:1 is an arbitrary starting point. But if you don't get that part right, your starting point makes it hopeless to even be in the right ballpark. Link to comment Share on other sites More sharing options...
