MD 0150 CONCERNING SNOW SQUALL FOR PORTIONS OF WESTERN INTO EASTERN NEW YORK…EXTREME NORTHEAST OHIO…WESTERN INTO CENTRAL PENNSYLVANIA
Mesoscale Discussion 0150
NWS Storm Prediction Center Norman OK
1034 AM CST Sat Feb 17 2024
Areas affected…portions of western into eastern New York…extreme
northeast Ohio…western into central Pennsylvania
Concerning…Snow Squall
Valid 171634Z – 172130Z
SUMMARY…Snow showers should persist over the next several hours in
tandem with diurnal heating across much of central NY into PA. Brief
bursts of heavier snow may support very localized reductions in
visibility.
DISCUSSION…Boundary-layer heating is supporting the generation of
steep (i.e. 8 C/km) low-level lapse rates, which is encouraging the
generation and sustenance of scattered, low-topped convective snow
showers over portions of central NY into PA. A mid-level trough is
traversing the region, providing enough deep-layer ascent for
continued snow-shower development through the afternoon. Based on
reports over the last couple of hours, brief bouts of reduced
visibility (as low as a quarter to half a mile) have occurred. Given
the convective nature of these snow showers, brief and localized
bursts of heavier snow will remain possible through the afternoon on
an isolated basis, until the steep low-level lapse rates diminish
later today.
