Springtime Snow in Eastern USA

A warm spring across the eastern United States, bursting with blossoms
of crocus, daffodils, and cherry blossoms, was interrupted by a quick
but impressive reset to winter weather in late April 2022. On April
18-19, a strong winter storm brought snow, rain, hail, and fierce winds
to parts of the Mid-Atlantic and most of the Northeast, knocking out
power, making roads impassable, and creating flood conditions in many
locations. The storm dumped up to 18 inches (46 cm) of snow in parts of
the Catskill Mountains of New York State and set records in parts of
New York and Pennsylvania. According to the National Weather Service,
14.2 inches (36 cm) fell in Binghamton, New York, smashing it’s
previous two-day April snowstorm record of 13.6 in (34.5 cm) set in
2007. More than 300,000 homes across the Eastern U.S. were reported
without power as of mid-day on April 19.

The storm turned deadly near Annapolis, Maryland, where temperatures
had reached 86˚F (30˚C) on April 13. Although the storm didn’t bring
snow to this area close to the Chesapeake Bay, temperatures plunged 33
degrees, heavy rain interspersed with hail drenched the region, and
strong winds battered the city. The soil-soaking storm combined with
fierce gusts of wind caused a tree to fall on a house just outside of
Annapolis, killing one man and injuring two other people.

By April 20, when the Moderate Resolution Imaging Spectroradiometer
(MODIS) on board NASA’s Aqua satellite acquired a stunning false-color
image of the snow-struck region, skies had cleared, temperatures had
warmed, and gentle popcorn clouds dotted the sky around the Great Lakes
and over the heaviest snow in New York. High temperatures in
Binghamton, New York, which had plunged from 73˚F (22.8˚C) on April 13
to 36˚F (2.2˚C) on April 19, had risen to 46˚F (7.8˚C) by April 20,
and—except for lingering snow—spring had once again returned to the
Eastern United States.

This image was created by using MODIS bands 7, 2 and 1. In this
combination, vegetation appears bright green, clouds are bright white,
water looks inky-blue, and snow appears electric blue. Where the sky is
clear, the blue snow stands out in vivid contrast to the surrounding
clouds, lakes and rivers, and spring vegetation.

The image centers on New York (north) and Pennsylvania (south of New
York) and includes parts of New Jersey, Delaware, Maryland, and West
Virginia along the lower border. Three large areas of snow sit in New
York, with the heaviest east of Lake Ontario. Snow in Pennsylvania sits
primarily east of Lake Erie and along the highest elevations of the
Appalachian Mountains. Snow in the Appalachians continues through
western Maryland and West Virginia.
