900 PM EDT.
* Primary threats include...
A couple tornadoes possible

SUMMARY...Thunderstorm intensity has recently increased from central
New York across eastern Pennsylvania, in the vicinity of a warm
front moving northward/northeastward across the region. Deep-layer
shear is forecast to increase with some increase in low to mid-level
flow as well. This increased shear could support some more organized
storm structures capable of producing tornadoes as these storms
continue eastward. Damaging gusts are possible as well, particularly
as storms trend towards a more linear structure over time. Another
round of storms is possible later this evening, and some severe
threat will accompany these storms as well.
The tornado watch area is approximately along and 60 statute miles
east and west of a line from 30 miles northwest of Albany NY to 20
miles south southwest of Wilmington DE. For a complete depiction of
the watch see the associated watch outline update (WOUS64 KWNS
WOU7).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.
