...SNOW SHOWERS ACROSS THE WESTERN SOUTHERN TIER AND BOSTON 
HILLS WILL PRODUCE LOCALLY HEAVY SNOW LATE THIS EVENING...

Snow showers will move across the Western Southern Tier and the 
Boston and Wyoming Hills this evening. These will produce brief 
bursts of heavy snow, which will lower visibility below a half mile 
at times and cause 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 16.
