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.
