...AN AREA OF BRIEFLY HEAVY SNOW SHOWERS WILL AFFECT WESTERN 
WAYNE...WYOMING... CATTARAUGUS...SOUTHERN ERIE...LIVINGSTON... 
CHAUTAUQUA...NORTHERN ALLEGANY...GENESEE...MONROE AND ONTARIO 
COUNTIES...

At 341 PM EST, an area of briefly heavy snow showers was located 
along a line extending from near Rochester to the western Southern 
Tier, moving east at 40 mph.

Wind gusts near 40 mph combined with a few brief bursts of heavy 
snow will greatly reduce visibility at at times. Most roads will 
remain just wet, although a few slick spots are possible in the 
heaviest snow showers, especially across higher terrain.

Conditions can deteriorate rapidly in winter weather situations. Be 
prepared for greatly reduced visibility at times. Slow down and 
allow extra time when traveling.
