  1. It's part of the fraud five for a reason, but every once and a while the backlash snow comes together.
  2. Some academic types have a very specific definition for sting jet, so we may overuse that phrase (I'm going to have to read more up on specifics) but this is impressive however you want to categorize it.
  3. Not really seeing any gravity wave signatures on pressure traces, could just be a good old fashioned isallobaric burst coupled with a good descending jet.
  4. Seeing a lot of sustained 30+ knots. Pretty impressive.
  5. There appears to be another wave just south of LI (can see it in low level WV imagery). I'll be interested to see if there is another burst of relatively higher wind gusts incoming.
  6. That's the rub. Models notoriously overforecast QPF in the dry slot, but what does fall will likely be more efficient like drizzle.
  7. I'd say that's about ballpark what I think of in my head, 0.3" power issues, 0.75" disaster area.
  8. We use the FRAM method, which more or less drops to 50% run off once precip rate is over 0.1"/hour.
  9. The radial idea I believe came from original load testing on utility lines. They were rated by the radius of ice accretion. So the formula for reporting to the NWS became: (thickness on one side + thickness on the other - thickness of the branch/line)/2. Because even if you had an inch of ice on your hypothetical branch, reporting 0.5" radial accretion is still the same amount of ice and weight on that branch. However, flat ice accumulates totally differently than on branches or lines.
  10. Will is right, flat ice to radial is 40%. Anecdotally that's what we hear from utilities. Around 0.3" you start getting power issues. And it wouldn't be that drastic a jump from 0.5 to 0.75" vs going all the way to an inch or more.
  11. Honestly I think the directive was updated recently to explicitly state elevated flat surface. So New England is kind of trying to increase our criteria closer to 0.75" for a warning. If we were doing a high level briefing for ice I think we would still produce radial ice maps for utilities to use though.
  12. Well the ASOS measurements are relatively new, so we're kind of standardizing them now. We have typically forecast radial and measured that way in New England. I think part of spotter training going forward needs to focus on stating your measurement method and the NWS will have to decide how to report it on an LSR (e.g. reporting flat but remarking that it was taken radial). NWS is supposed to forecast flat ice now. This was never how it was done regionally. So ice storm criteria of 0.5" is more akin to damage expected from radial accretion. If we issued ice storm warnings for flat ice that's like 0.2" radial. That's not going to be much damage.
  13. The math checks out. It's good to remind everyone that ASOS measures an elevated flat surface, so not your typical power line or tree branch radial measurement. That conversion would be more like 0.15" ice.
  14. From the very end of the Knife's Edge (we didn't hike it but walked over to the start of it just to peek) and that second one is actually Baxter Peak from Hamlin.
  15. Winter's over for the picnic tables, time for everyone else to cash in.
  16. I'm now looking up how feasible trips to Torngat and Gros Morne would be from Maine.
  17. I've always thought getting a cabin on a lake up in PQ for a week would be a very relaxing vacation.
  18. Moosehead is definitely starting to get into that zone where the trees are all a little smaller and you start to feel like you're getting towards the edge of the Earth. I can only imagine what the tundra of Quebec must look like.
  19. Definitely no weather equipment at the top permanently (maybe one off research projects at times). Closest you'll get is weather data from Chimney Pond ranger station, and even then I don't think any of it is online in a timely fashion.
  20. Those days of having family memberships to country clubs are even slipping away. Not many people have that kind of disposable income. I'd love to do it (and my wife is even on board with the idea!) but it comes down to $3000 plus monthly food vs. a vacation or two (or more likely preschool).
  21. High's in a decent spot on the ensembles.
