Potential for Major East Coast Blizzard Next Week

Snow from the recent nor-easter was largely restricted to higher ground on the east coast and for inland areas. Therefore, the wait goes on for the first proper snowfall of the season for many, especially those on the east coast. It has been a few years since places like NYC experienced a proper snow storm / blizzard. There are tentative signs that the first major snow storm of the season may hit the east coast next week. The GFS produces a strong low across the mainland on the 16th, before producing a significant snow event for the east coast on Thursday 17th December. The snowfall accumulation maps for this model run suggest over 8″ (20cm) for NYC, and more inland for cities such as Albany.

Of course, uncertainty is very high as this is a long way off, in meteorological terms. However, the slightly increased risk of more significant low pressure developments during this period needs to be highlighted. The ECMWF does also have a similar area of low pressure which produces again, high amounts of precipitation, however the “warm sector” associated with the nor-easter is further north and as a result most of the east coast experiences rain / sleet as opposed to snow. This again highlighting the significant uncertainty. Keep an eye on local forecasts for next week, esp 16th to 18th, for any warnings which may arise.
