  1. I’m about 4 miles NW of you and have about 150’ elevation. It is 4 degrees warmer here. Looks like we set up an inversion, which also tracks because the air quality got worse in the last few hours too.
  2. Temp bounced a bit, though it is really pretty irrelevant. 31.8 00z HRRR is ok, but flips to sleet in DC earlier (22z).
  3. The precip is just so light at that point, though. We can add some fluff, but the last 6 hours of the Nest is 0.1-0.15” liquid.
  4. 0.7” QPF, though I’d use the 3km at this range. 4-6” is looking good. NAMs don’t have much on the back.
  5. Yeah, it’s a transfer. You can see the 12z Euro does the same, just with a different, more southerly orientation that helps us out some.
  6. We get the 700 wind vector pointed at us, but it is not a nice moist fetch off the ocean, it is a very long route over NYC and the coming in from the north. Just not much left by the time it gets here. 06z Monday to 06z Tuesday. Not much after either.
  7. Our worst-case scenario seems to be the 00z NAM Nest dry front side and the 00z 12km NAM dry backside. That’s about a 3” storm for many of us along 95.
  8. And on queue, the NAM 3km is very dry on the front side again. 0.2” QPF by 00z Monday.
  9. The caveat is that after a few runs of the 3km NAM being dry, I’m not sad to see 0.6” qpf on the other mesoscale model prior to 00z.
  10. 12km NAM holding serve with a very wet front side. 6” WAA thump.
  11. Say what you want about the GFS, but this is pretty good precip field consistency in our area.
  12. 6 hr precip 12-18z Monday on the RGEM. Actual numbers irrelevant, but the placement...
  13. At 700 the low is more elongated SW to NE, which helps. I can't say what the cause of that is, though.
  14. I'm looking at the initial vort that comes around the base of the trough at ~hr 54. That makes more progress in the 18z run than it did at 12z. It is subtle, but might be helping.
  15. I don't know. It is better to compare it to the other front-end projections, not the 12km NAM since we know that one is often wet.
  16. 700 frontogenesis - NJ is the winner in the NAM run.
  17. Nest is still drier on the front end. 0.2-0.4" QPF by 00z Monday.
  18. The 11:35am 5-min ob. I actually made it to 33.7 at home.
  19. The Euro and NAM continue to be the models with more impact from the energy moving through Canada and New England.
  20. Para GFS (v16) is drier and colder than the OP. 0.75-1" QPF total. Kucera 6" near DC, closer to a foot by the PA border.
  21. The GFS is a bit on an island with the 00z to 12z Monday period. Most of the models have a pause or lighter precip. The GFS has significant (0.5"-1.0") precip during that timeframe. The struggle is of course that this is the most likely period to have thermal troubles.
