Mesoscale Discussion 1804

Areas affected...portions of eastern Pennsylvania...the DelMarVA and
into western New Jersey/southern New York.

Concerning...Severe Thunderstorm Watch 591...

Valid 031853Z - 032000Z

The severe weather threat for Severe Thunderstorm Watch 591
continues.

SUMMARY...Gradual upscale growth into bands and clusters  is
possible through this evening. Damaging gusts are likely across
WW591.

DISCUSSION...The severe risk continues with scattered storms ongoing
across WW591 as of mid afternoon. Remaining inhibition has largely
been negated and additional storm development/intensification should
continue across much of the mid Atlantic. A few stronger cells have
emerged over eastern PA and northern MD/VA over the last couple of
hours. Early indications are that these storms may gradually evolve
into more organized clusters or linear segments with time owing to
the modest mid-level shear. Recent HRRR guidance also suggests
continued intensification is possible this afternoon. Damaging gusts
(some to as much as 60-70 mph) are possible with the strongest
storms should they begin to consolidate. Additional storms may also
develop through the day with at least an isolated severe risk
possible with any longer-lived clusters.
