Mesoscale Discussion 1083
NWS Storm Prediction Center Norman OK
0530 PM CDT Thu Jul 02 2020
Areas affected...Southeast New York into Maine
Concerning...Severe potential...Watch unlikely
Valid 022230Z - 030030Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated damaging winds remain possible with ongoing
thunderstorms. A watch is not likely given the isolated nature of
the threat.
DISCUSSION...Thunderstorms that have developed along a surface
trough, and in the vicinity of a surface low in place across
southern ME, continue to move to the south within a northerly flow
regime featuring 30-35 knots of effective bulk shear. These storms
have already produced a couple instances of damaging winds across
eastern NY and pea sized hail has been noted in ME. Given the
mentioned shear and 500-1000 J/kg of MLCAPE, storm organization
remains possible for the next 1-2 hours before storms move offshore
or into a more stable air mass to the south. Given low-level lapse
rates around 8 C/km in place across the region, isolated damaging
wind gusts should continue to be the primary threat. An instance of
severe hail can not be ruled out, but given a more linear storm move
across southern ME and outflow-driven storms in NY, the hail threat
appears to be low. Given the isolated nature of the wind threat, a
watch is not likely.
