Areas affected...Parts of the Mid-Atlantic

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

Valid 141802Z - 142030Z

Probability of Watch Issuance...20 percent

SUMMARY...A few instances of marginally severe hail and damaging
gusts are possible across parts of the Mid-Atlantic through the
afternoon. A watch is not expected.

DISCUSSION...Isolated to widely scattered thunderstorms are evolving
eastward across parts of southern PA into eastern WV and western VA
this afternoon -- where a 1-inch hail report occurred earlier.
During the next few hours, this activity will generally
spread/develop eastward across the Mid-Atlantic region, where a
plume of diurnally steepening low-level lapse rates is developing.
Given around 30 kt of effective shear and the increasingly unstable
pre-convective environment, marginally severe hail and locally
damaging gusts are possible with any stronger multicell clusters or
transient supercells that develop. The overall severe threat should
remain too isolated/sporadic for a watch.
