MD 2071 CONCERNING HEAVY SNOW FOR WESTERN NEW YORK STATE
Mesoscale Discussion 2071
NWS Storm Prediction Center Norman OK
0347 PM CST Fri Dec 23 2022
Areas affected...western New York State
Concerning...Heavy snow
Valid 232147Z - 240245Z
SUMMARY...Heavy lake-effect snow and localized blizzard conditions
to continue this evening. Rates of 2 in/hr possible.
DISCUSSION...As of 21:45 UTC, regional radar showed a well-developed
lake-effect snow band ongoing across the eastern shores of Lake
Erie. A post-frontal arctic airmass with strong southwesterly flow
is evident on the Buffalo VAD/VWP with a well-defined 60-70 kt
low-level jet parallel to the lake axis. Strong convergence and warm
lake temperatures will continue to support banding and heavy snow
across the eastern shores through this evening. Rates of 2 in/hr
will be possible within the primary band close to the lake shore
where convergence and convective effects are strongest. In addition,
the strong winds aloft will continue to support strong surface gusts
greater than 50 mph through this evening. Localized blizzard
conditions are expected along the immediate lake shore where heavy
falling and blowing snow will support zero visibility.
