1246 PM EST SAT NOV 10 2018

...BANDS OF LAKE EFFECT SNOW WILL AFFECT JEFFERSON...LEWIS AND
NORTHERN OSWEGO COUNTIES...

A broken band of lake effect snow over much of Lewis County will
merge with an approaching band of snow showers along a cold front,
resulting in a brief snow squall moving from northwest to southeast
across much of the eastern Lake Ontario region and dropping a quick
inch of accumulation.

Winds in excess of 40 mph are possible with this snow squall,
producing blowing and drifting snow.

This includes Interstate 81 between exits 38 and 52.

Use extra caution if you must travel into or through this snow
squall. Rapid changes in visibility and potentially slick roads are
likely to lead to accidents. Consider delaying travel until the
squall passes your location.
