...Strong to severe thunderstorms possible later this afternoon
and evening...

A cold front crossing Ohio during the midday will push across
western and north central New York later this afternoon and
evening. This front will generate more showers along with the
likelihood of strong to severe thunderstorms.

Winds aloft will be dangerously favorable for any thunderstorm to
contain damaging winds of 60 mph or greater. For parts of the
Finger Lakes Region and sites east of Lake Ontario where there has
been at least partial sunshine through midday...winds aloft will
also support supercells that could include isolated tornadoes.

The severe weather potential will be greatest between 3 and 6 PM
for the far western counties...between 5 and 7 PM for the Finger
Lakes region...and between 6 and 9 PM for the Eastern Lake
Ontario region.

Along with the risk for widespread severe weather...there will be
heightened concern for flooding due to slow moving downpours and
very wet existing conditions. The threat of hydrologic issues will
be greatest over the western counties.
