  1. 1/20 18Z Total QPF ICON: (120H) in line with 12z GFS: 0.3 - 0.4 GFS AID: 0.5 - 0.6 GEFS: 0.6 Euro AI AIFS: 0.6 - 0.7 Euro : 0.9 - 1.1(+) through and more to come (144H)
  2. One consistent trend is this is more a Sun (PM) - Mon (PM) or even early Tue (AM) event.
  3. Final 12z - solid snowstorm on 8 of 9 outputs
  4. Good catch that was meant to be a 20 (2/12/2012) I will update
  5. 06z only goes to 144 00z (/20) was 1.0 (QPF) and now 0.7 - NYC
  6. Bottom-line guidance (recent assessment) Best single model for East Coast winter storms: ECMWF IFS Best long-range track sanity check: GraphCast / AIFS Worst use of AI: trusting snowfall maps or precip type Best blend: AI for where, physics for how much & what type
  7. GGEM 0.8 yields 8 inch at 10:1 and over a foot with >12:1 ratios.
  8. 12Z QPF Totals (NYC) ICON: 0.9 - 1.1 GFS: Trace GGEM: 0.6 - 0.8 GEFS: 0.5 - 0.6 UKMET: 1.00 - >1.00 Euro AI AIFS: 0.5 - 0.6 Euro: 0.7 - 0.8 GEPS: 0.9 EPS: 0.6 - 0.7
  9. It'll be interesting to see the GEFS mean (12z) Op vs Ensembles
