A strong squall line pushed across the tri-state
area Friday morning, with rare wintertime Severe Thunderstorm Warnings issued
for parts of New York City and New Jersey. Gusts were recorded
between 40 and 70 MPH across the region, including 58 MPH in
Brooklyn, NY and 69 MPH in Barnegat, NJ.
February severe storms are quite uncommon but
not unprecedented. A total of nine severe thunderstorm warnings
have been issued for New York City since record-keeping of warnings began in
1986. The last February severe thunderstorm warning in New York City was on
Feb. 25, 2016. And only three severe warnings in the month of
February contained a hail signature, until Friday's warning became the
fourth.
While Friday's squall has pushed offshore,
another squall arrives Saturday — but this time the wintry kind! A snow
squall will develop across the Great Lakes tonight and pass through
the Tri-State by midday tomorrow.
By definition, a squall is a quick-moving,
narrow line of heavy precipitation and strong wind. Impacts from
Saturday's winter-like squall line will be different from Friday's summer-like
squall.
A summertime squall line contains
strong-to-severe thunderstorms. Some produce downpours, frequent
lightning, pea-size hail or greater, and damaging winds of 58+ mph. Downed
trees, power lines, and rapidly deteriorating travel conditions are
the main impacts. Friday's squall certainly contained summer-like characteristics.
A wintertime squall line, contains a burst
of heavy snow and gusty winds of 40+ mph. Snow can accumulate quickly because
of the intense snowfall rates, typically of 1" or greater per hour.
Reduced visibility and hazardous driving conditions are the biggest impacts
from a snow squall. Those impacts are in the forecast across northwestern New
Jersey and the Hudson Valley on Saturday.
However, no matter the season, all squalls
are fast-moving. Squall lines typically move at 40 to 60+ MPH and last about
15-to-30 minutes.
