...AN AREA OF HEAVY SNOW WILL AFFECT NORTH CENTRAL ERIE AND NIAGARA
COUNTIES...

At 800 AM EST, a line of snow showers dropping south from Lake 
Ontario this morning will produce a burst of snow which will reduce 
visibility to below a half mile at times. Although this will only 
produce a half inch to an inch of snow, it will result in slick 
travel conditions for this morning commute. 

The snow will move into the Niagara Falls area and Grand Island 
through 9 AM. Motorists should be prepared for poor travel 
conditions, and allow some extra time for the morning commute.

Locations impacted include...
Niagara Falls, North Tonawanda, Lockport, Amherst, Grand Island,
Newfane, Pendleton, Lewiston, Youngstown, Middleport, Sanborn, Fort
Niagara State Park, Wilson, Barker, Cambria Center, Pendleton Center,
Ransomville, Rapids, and Gasport.
