Mesoscale Discussion 0035
NWS Storm Prediction Center Norman OK
1245 PM CST Mon Jan 13 2025
Areas affected...south-central New York into far northern
Pennsylvania
Concerning...Snow Squall 
Valid 131845Z - 132045Z
SUMMARY...Snow squall activity will be possible through the
afternoon diminishing through the evening.
DISCUSSION...Radar across southern New York state this afternoon
shows several snow showers moving eastward along a surface cold
front. A few of these showers have had brief increase in intensity,
with visibility reductions to 1/2 mile reported. The thermal
environment is characterized by somewhat poor low-level lapse rates,
owing to cloud cover across the region. However, surface objective
analysis does indicated some 2-6 AGL lapse rates around 7 C/km right
along the front. The occasional snow squall will be possible, with
sudden visibility reductions to less than 1/4 miles and gusty winds.
This threat will subside with passage of the front, and as sunset
approaches with loss of daytime heating.
