Valid 131300Z - 141200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Organized severe thunderstorms are not expected.
...NY/PA...
a fast-moving and well-defined shortwave trough is indicated over
WI. This feature will track across the Great Lakes and affect parts
of PA/NY later this afternoon and evening. Strong low-level warm
advection and lift will aid in the development of showers and
isolated thunderstorms over southern Ontario and parts of
central/western NY/PA. While lightning activity will likely be
sparse, strong low-level winds and steepening mid-level lapse rates
could result in gusty showers and thunderstorms with isolated severe
winds possible.
...FL...
A few afternoon thunderstorms are expected today over central/south
FL, along and ahead of a surface cold front. Weak winds aloft
should preclude severe storms.
