I thought I’d save a few forecast graphics now, to see how they hold up when the snow event is over. First, here’s the one from NWS Boston. I can’t say I much like their color scheme, as it gives a reverse visual impression (IMHO) to what the numbers say.
The probability map color scheme makes more visual sense to me:
This is from the NWS Facebook Page:
…MAJOR Blizzard Expected for Boston and New York City…
Total accumulations of 18 to 24 inches are expected for southeast Maine, eastern and southeast Massachusetts (including the Boston metro area), northern Connecticut and all of Rhode Island. Further south across eastern New York to Northern New Jersey, total accumulations of 8 to 15 inches are expected, including the New York City metro and Long Island. Light snow will develop by Friday morning, becoming heavy late in the day into the evening commute. The heaviest snowfall, particularly along the Interstate 95 corridor, will fall Friday night into Saturday. North-northeast winds gusting up to 60 mph will lead to blizzard and white-out conditions, creating life-threatening travel conditions. Damage to trees and structures with scattered power outages are anticipated.
In addition, moderate to major coastal flooding is expected from Portland, Maine to the east facing coastline of Massachusetts.
Take a look at HPC’s Day 1-2 QPF. Although all eyes are on New England with the impending major winter storm, the East Coast is expected to get a good amount of rainfall over the next day or two. To see more information about this, visit our QPF page: http://www.hpc.ncep.noaa.gov/qpf/day1-2.shtml
