  1. I should be specific about my vectors. Friction acts opposite to the real wind. The reduced speed reduces coriolis so the pgf (pressure gradient force) becomes dominant and the flow turns more ageostrophic over land. It’s basically an ekman spiral.
  2. What also happens is friction causes an ageostrophic component to the wind. When you have onshore flow the wind inland is turned to the left or cyclonic. That helps to create extra convergence just inland with onshore flow.
  3. In random 12z model news… The frenchy was a good hit for BOS and SE MA with some snow up here, and the chinese and korean were cape hits with some snow back to BOS but nada here.
  4. Yeah we don’t need that. 38 and sun I’m fine with.
  5. Pushing -40 in ME. Coldest I see so far is -38 in Masardis. Still dropping here. -11.5°
  6. Hopefully we get a nice break from the cold next week. Melt some snow and ice away.
  7. -10 but I’m one of the warmer spots in the area on my hillside.
