Areas affected...parts of eastern Pennsylvania...New
Jersey...Delaware and eastern Maryland and southern New York
Concerning...Severe Thunderstorm Watch 107...
Valid 012037Z - 012230Z
The severe weather threat for Severe Thunderstorm Watch 107
continues.
SUMMARY...Storms may rejuvenate along the front as it moves into
eastern Pennsylvania and southern New York, with additional develop
possible ahead of the front from the Delmarva into New Jersey.
Damaging winds are likely, with a risk of isolated tornadoes and
large hail by early evening.
DISCUSSION...Showers and embedded thunderstorms continue to move
rapidly east with the cold front, with a relative decrease in severe
wind gusts compared to earlier in the day, due in part to limited
moisture. East of the ongoing central PA/NY activity, temperatures
continue to warm, with a recent trend of a few stations reporting
rising dewpoints across southern NJ and far southeast PA.
Satellite imagery shows increasing CU over parts of MD, though this
activity is currently shallow. Over the next 1-2 hours, additional
storms are expected to form from the Delmarva across far eastern PA
and into NJ, as lift increases. Some storms may become supercells,
and the tornado risk will also increase through early evening
coincident with strengthening low-level shear and cooling aloft. Any
increase in dewpoints will also increase the probability of a
tornado. Activity may become linear as the cold front overtakes any
activity ahead of it, with both damaging winds possible across
southern NY and New England.
