  1. Haha- I wouldn't mind kicking it out of the thread, but I meant also out of SNE. I have an irrational fear it will effect the larger storm.
  2. When has it been established the eps tends to be amped
  3. "As you learned earlier, meteorologists compensate by implementing a technique called ensemble forecasting, which gauges the sensitivity of a computer model's prediction to the way it's initialized. Specifically, meteorologists make minor changes to the initialization of a lower-resolution version of a specified operational model called the control member. For example, the control member in the GEFS has lower resolution than the operational GFS model. At any rate, the control member is run using this slightly different initial state. Then meteorologists tweak the initialization of the control member yet another time, in a slightly different way, and run the control member again using this new initial state. This process of "tweaking" the initial conditions of the control member is repeated a number of times (for some models, several dozen times), yielding a set of ensemble members. If all or most of the ensemble members come up with basically the same numerical prediction for a specific forecast day, meteorologists have a relatively high degree of confidence in that day's forecast. If, however, the tweaked model runs predict several noticeably different scenarios for the day in question, then forecasters have a fairly low degree of confidence in the numerical prediction."

  4. Well, it's tricky to explain effectively. Essentially we use ensembles because we don't understand the uncertainty of our chaotic atmosphere. Taking into account this uncertainty, the model runs several times with slightly perturbed conditions in order to create the individual members in order to best account for all possibilities. That's how we get the ensemble mean. The ensemble control forecast is the ensemble member run from the unperturbed, coarse-resolution initial conditions. Essentially the control run is useless in conclusion
  5. Next metfan will be posting individual member runs of the ensemble. It'll be like AccuWeather in 2007 here
  6. Really? Posting the control of the ensembles? Good lord
  7. Yes - agree with that. Makes a ton of sense. Our average Temps will rise. But a 1040 hp nosing in from our north will always drag cold air down in front of an approaching noreastern. Temp increases won't change our patterns. But they may intensify the boundaries. I'm no scientific genius but that's the way I look at it anyway. Can't ignore the effect increased Temps would have on ocean sst though. Coastal locations may suffer a bit more and see a decreased seasonal window for snow imo..
  8. The Geography of our location should prevent snow averages from changing much and in my opinion global warming could only intensify and increase snow totals...
  9. I get the feeling the minute radar flips to light snow
  10. Oh certainly, I just looked at the calendar and realized we're a week away. God help us
  11. I only care if it shows snow for metfan in NYC to be honest
  12. You have to be bullish looking at these ensemble runs. I could care less about the individual op runs at this stage. Credit to guys like Ray etc who really called their shot with this pattern. Truly impressive.
  13. Do these NYC weenies have a return address?
  14. Miller B's are probably my favorite type of storm. One thing I miss, that we haven't had much of lately, clippers... I love the fact the snow sticks right away a lot of the time due to cold air
  15. OT... But just a reminder... If you haven't joined the subforum Facebook group and are interested... Here you go.. It's just a back up if the forum ever undergoes maintenance or the website has issues during events https://www.facebook.com/groups/Amwxsne/?ref=share
  16. I'd be OK with cutters, better than slowly bleeding out like yesterday
