MD 0919 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR PORTIONS OF NEW ENGLAND
Mesoscale Discussion 0919
NWS Storm Prediction Center Norman OK
1137 AM CDT Fri Jun 02 2023
Areas affected...portions of New England
Concerning...Severe potential...Watch unlikely
Valid 021637Z - 021830Z
Probability of Watch Issuance...5 percent
SUMMARY...Thunderstorms with marginal severe wind threat possible
through the afternoon. Watch issuance unlikely.
DISCUSSION...Thunderstorm development is expected to continue
through the afternoon across portions of New England amid a modestly
unstable air mass. Daytime heating and dew points in the mid 50s to
low 60s have resulted in MLCAPE values around 500-1000 J/kg. An
increase in cumulus across convergence near the higher terrain has
been observed, with a few cells developing. Forcing from a weak
shortwave will help further increase thunderstorm coverage through
the afternoon. Storm mode will likely be a mix of clusters, given
weak shear profiles and best flow largely behind a cold front well
to the north. Sounding analysis shows inverted V profiles with drier
air in the low-levels, suggestive of potential for a few microbursts
and marginal threat of severe wind. Given the more sporadic and
isolated nature of this threat, a watch is not being considered.
