  1. https://www.weather.gov/wrh/hazards?obs=true&wfo=gyx&hazard=true&hazard_type=all&hazard_opacity=80&tab=legend Choose the obs tab and zoom and increase the density
  2. Either maybe something convective went through and it was heavily rimed flakes/graupel or maybe nucleation is getting poor at times and you’re getting supercooled droplets in the cloud layer freezing in the cold dome.
  3. Whatever…it’s a term Will and Ekster coined 2 decades ago with SW flow aloft. Overrunning, SWFE, isentropic lift…same diff.
  4. In the end it just comes down to a number. The liquid equiv will be what it is. By the end of the week the pack will look the same whether it started as big dendrites or little plates and needles.
  5. Those are pretty rare. ASOS struggles to go below 1/4SM. They just report it as M1/4SM. Manned obs can go lower with 3/16, 1/8, 1/16, or 0.
  6. SWFE on roids + cold temps. You get a dense amount of crystals and grow them large. That does a real number on the vis.
  7. You can really see the midlevel bands from ENX over SNE. That would probably explain the intervals of regular growth and big growth.
