Mesoscale Discussion 2251
NWS Storm Prediction Center Norman OK
0214 PM CST Fri Dec 06 2024

Areas affected...portions of western New York

Concerning...Heavy snow 

Valid 062014Z - 070115Z

SUMMARY...Lake-effect snow rates approaching 2 inches an hour are
possible into the evening hours.

DISCUSSION...A lake-effect snow band is ongoing across portions of
Lake Ontario, which is impinging on Oswego County NY and is
producing heavy snow based on the Fulton/Oswego County Airport ASOS.
Some slight backing of the low-level winds from northwesterly to
westerly, as shown by surface observations, will support a longer
fetch of moisture across Lake Ontario. These backing winds may help
intensify the ongoing snow band, as well as encourage this band to
take on a slightly more west-to-east orientation over the next
several hours. While at least one inch/hr rates are likely in the
immediate term, snowfall rates approaching 2 inches/hr may be
possible later this afternoon and evening.
