...SNOW SHOWERS ACROSS THE WESTERN SOUTHERN TIER WILL PRODUCE 
LOCALLY HEAVY SNOW LATE THIS AFTERNOON...

Snow showers will move across the Western Southern Tier through 630 
p.m. These will produce brief bursts of heavy snow, lowering 
visibility below a half mile at times and causing slick travel 
conditions. Snow showers will be brief, with any snow accumulation 
less than an inch. However, rapidly lowering visibility and slippery 
spots will impact those traveling through the area. Motorists should 
exercise caution.

 This includes the following highways...
 Interstate 90 between exits 61 and 58.
 Interstate 86 between exits 4 and 33.
