. . . The LES band remained south of Y62 throughout the afternoon. However, animated imagery shows it was moving slowly northward, with extrapolated arrival at the station by dusk. Unfortunately, cirrus cloudiness moved into the region just as this was occurring. Since there was no radar coverage over the area, and since the low-level clouds were hidden more than 50% of the time by after about 2200 UTC, the evolution of the LES band cannot be analyzed effectively. All that can be said about this period is that heavier snow began at about 0250 UTC (09 Dec) at Y62. Surface winds at Y62 were southeasterly at 10 - 15 kts through 1250 UTC in advance of the approaching cold front, when they switched to southwesterly. Throughout the night, snowfall was categorized as S or S+, with most observations including the comment "SNOINCR" (i.e., an inch or more accumulation in the previous hour). Hourly water equivalents at Y62 show that the precipitation increased at the front got closer, so that part of the snowfall during the heaviest period may have been due to pre-frontal lift. The heavy snowfall trickled off to S- by 1550 UTC with hourly liquid equivalents after that time running in the 0.01" to 0.03" range. Sky coverage went to broken by late afternoon. Overnight snowfall at Y62 totaled 24.7", most of which fell in the six hour period from 0645 to 1245 UTC.
