[html]MD 1651 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EASTERN PA INTO SOUTHERN NEW ENGLAND
Mesoscale Discussion 1651
NWS Storm Prediction Center Norman OK
0227 PM CDT Thu Aug 04 2022
Areas affected...Eastern PA into southern New England
Concerning...Severe potential...Watch unlikely
Valid 041927Z - 042130Z
Probability of Watch Issuance...20 percent
SUMMARY...The threat for primarily isolated damaging gusts will
spread northeastward this afternoon.
DISCUSSION...Sporadic damaging winds and observed gusts up to 40-45
mph have been noted recently when convection spreading northeastward
across northeast PA into central/southern NY. Deep-layer shear
remains weak across the region, but unidirectional southwesterly
flow will continue to support occasionally vigorous redevelopment
along a northeastward-propagating cold pool. Moderate downstream
instability (MLCAPE of 1500-2000 J/kg) and steep low-level lapse
rates will continue to support a threat of localized damaging wind
gusts as storms spread toward southern New England through the
afternoon. With the threat still expected to be relatively
disorganized, watch issuance remains unlikely.
