High SN:H2O were observed in this morning early snowfall reports.
ORH - 23:1
CON - 24:1
BDL - 25:1
Ratios are well above normal.

12z Skew-T from GYX shows cloud-top ~-18°C...the cold edge of favored stellar dendrite growth region. Note the strong warm-air advection near 700 mb acting on the elevated moist layer where mixing ratios reach their maximum value.
