  1. Normal 850 temps are 0 in mid-march for DCA, as opposed to about -4 in Jan. So they need to be below normal to support snow as long as the BL is saturated and/or isothermal
  2. Well maybe that big 50/50 will stick and manage to cool those waters a good bit
  3. @psuhoffman I’m not even sure its solely the pacific anymore like I thought it was back in Dec-Jan. Someone raised a good hypothesis earlier in this thread - what if [X factor] is responsible for amping waves out of the W too much too soon, instead of digging or sliding to the S of us? It makes sense if we consider the warmer gulf waters + carribean high supplying warm moist air to any wave that rolls over the rockies. So one of the two things has to happen - laws of physics - a) move further N/W across the baroclinic boundary that was/is being pushed north, or b) amplifies into a huge monster which isn’t good for us either because we don’t want an early phaser for a MA snow. What would it take for a third thing to happen? C) hold a ridge over the west, cool the Caribbean waters a tad, and get something to slide S of us.
  4. I’d say wait till the ens but I have a feeling they will move towards the op esp since op gfs seems to have latched onto a new idea
  5. 18z gefs seem to be weakening the epo ridge while intensifying ao/nao. Is there an analog for that?
  6. Could be that the models are underestimating the block and or overinitializing current conditions with the old pattern still in place.
  7. Ops seem to want to slow the vorts down and amp them, while many ensemble members kick them out faster and less amped.
  8. Both 12z op runs of the globals didn’t turn out good scenarios today. Hope this isn’t a sign of a trend.
  9. Sleet mixed in with rain. Pellets on deck. Ashburn, 40
  10. Obviously an op run without ensemble support is less credible than one with support. But it is still very much one of the possibilities that we cannot rule out. If it holds back and amps too much, this will be a miss for us.
  11. Let’s hope the ens are more correct and the op is wrong
  12. Yeah, that was just one of the many possibilities on the table. Something that could not be said all winter.
  13. Maybe noise, but gefs trended slightly east with the vort at 120
  14. You know it's getting real when Wes pops in. Good to see you in here.
  15. 2 ft area wide. But the usual disclaimers keep expectations in check yada yada lol
  16. Good set of runs so far tonight, curious as to what the euro will do but I’m going to bed now.
  17. Wacky evolution for sure. Probably won’t play out as depicted but hopefully moving closer to the right solution for us
  18. That march 7-8 cutter is going to play a crucial role both upstream and downstream.
  19. On march 6? That’s to be expected, imo. That cutter should absorb into and reinforce the 50/50, while the w trough begins to kick east on the 10th. Gfs moved towards the euro/cmc today
  20. Don’t know about you, but that doesn’t scream cutter to me.
