This work has resulted in a unique conceptual model of the ice habit and riming spatial distributions at the surface within the cyclone comma head. Changes in the height of the maximum vertical motion relative to the favored growth temperatures led to changes in ice habit throughout the comma head and two heavy snow bands. Cold type ice habits with a few plates and dendrites were observed with light riming as the surface low was located along or east of the Mid-Atlantic coast. As the cyclones move northward towards Long Island, moderately rimed dendrites, plates, and needles are generally observed. Heavily rimed needles and graupel are often observed near the warm front and cyclone center. Mainly needles with light riming and a snow-liquid ratio from 8:1 to 9:1 are observed 2 to 4 hours before two heavy snow bands. With the strongest frontogenetical ascent during snow band maturity, moderately rimed dendrites were observed with snow-liquid ratios from 11:1 to 13:1. Lightly rimed plates and a snow-liquid ratio of 8:1 were observed after the heavy snow bands. The WSM6, MORR, THOM2, and SBU-YLIN BMPs in the Weather Research and Forecasting model at 1.33-km grid spacing were validated in this study. A non-spherical snow assumption (THOM2 and SBU-YLIN) simulated a more realistic distribution of reflectivity than spherical snow assumptions in the WSM6 and MORR schemes. In heavier riming, the Doppler velocity in the WSM6, THOM2, and MORR schemes were ~0.25 m/s too slow with the SBU-YLIN was 0.25 to 0.5 m/s too fast.
