  1. Quite a few control freaks in this thread. Best not fret over something that is entirely unpredictable and will always be..
  2. Norfolk is part of Northern VA as much as it sits on the Pacific Ocean.
  3. The GFS showed essentially the same thing for a few straight runs on Fri and then lost it.
  4. posts in an obs thread but doesn't bother adding location
  5. that and zero orographic influence keeps the sustained banding away
  6. Maybe they're like Va and put it down 5 days before a forecasted storm that never materializes.
  7. I remember close to 6" of sleet in NoVA in one storm that year
  8. Must have picked up on what's looking like this early wave break
  9. HRRR is worthless for predicting band placement until it's inside 18 hours
  10. If low-level northeasterly flow holds longer than modeled, you can sustain snow or sleet even as the mid-levels warm, which models often don’t resolve well until you’re inside ~24–36 hours.
  11. Compare 850 winds and 850 0°C line at hour 42 on both runs, plus where the strongest fgen/omega sits. If the better lift shifts north or the 850 flow turns more S/SE, that’s your “colder run, warmer result” culprit.
  12. That’s the classic CAD/overrunning trap: the cold air is stubborn near the ground, but 850–700 mb winds can crank WAA over it. So you don’t dislodge the high, you just ride precipitation over it and introduce a warm nose. The surface map looks invincible, and meanwhile sleet is doing victory laps.
  13. NAM too dry? That would be a first..
  14. 2/2 and 2/3, right? Next week will be canceled before the first sleet pellet falls.
  15. Will you be issuing a Traveler's Advisory?
