Areas affected...much of Delaware into far southern New Jersey

Concerning...Severe potential...Watch unlikely=20

Valid 130443Z - 130615Z

Probability of Watch Issuance...5 percent

SUMMARY...A cluster of storms over eastern Maryland may persist for
a couple hours as it moves across Delaware and into southern New
Jersey, producing locally strong to severe gusts.

DISCUSSION...Several storms near Chesapeake Bay have congealed into
a rather impressive cluster given an environment of modest
instability and weak shear. Surface analysis shows ample moisture in
place with 70s F dewpoints, and temperatures aloft are relatively
cool as seen on point forecast soundings. The cluster is near a warm
front, and aided by southerly winds around 20 kt just off the
surface. A severe gust of 54 kt was recently measured at KMTN around
04Z.=20

Given the size of ongoing mass of storms, and continued inflow of
moisture and uncapped airmass, MLCAPE around 1000 J/kg, a continued
risk of isolated severe gusts is possible across DE and perhaps into
far southern NJ.
