Wild winds and spots of heavy snow marked the first nor’easter of the
winter season in mid-March 2023. From March 13-15, some high elevations
in New York, Vermont, Massachusetts, and New Hampshire saw 36 inches
(76.2 cm) of fresh snow with a few spots registering 40 inches (101.6
cm). Meanwhile, the storm brought wind gusts up to 60 mph (96.5 km/h),
downing powerlines and creating widespread power outages.

The chill didn’t last long, however. By March 17, most of New England
was enjoying temperatures over 50˚F (12.8˚C). The warm-up, combined
with showers scattered across the region, encouraged melting of the new
snow, especially in lower elevations.

On March 16, the Moderate Resolution Imaging Spectroradiometer (MODIS)
on board NASA’s Terra satellite acquired a false-color image of the
Northeastern United States and Southeastern Canada. In this type of
image, which uses MODIS bands 7,2,1, vegetation appears green, snow
looks electric blue, water looks deep blue, open land is tan, and
clouds can be white or—if they are cold, containing ice crystals—can be
tinted electric blue.

In this image, much of Canada lies under cloud cover, parts of which
stretch into the United States. Snow can be seen covering the ground
from the highest elevations of Pennsylvania’s Appalachian Mountains and
beyond the northernmost tip of Maine. In most areas, the snow does not
appear to be very thick, as it is tinted with the green of underlying
vegetation. Coastal regions, such as the hook-shaped Cape Cod,
Massachusetts, and southern states are snow-free.
