Mesoscale Discussion 1550

1139 AM CDT Sun Aug 23 2020

Areas affected...Central NY

Concerning...Severe potential...Watch unlikely 

Valid 231639Z - 231815Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated damaging downbursts possible over the next few
hours across central New York.

DISCUSSION...A few thunderstorms have developed near the central
PA/NY border over the past hour or so. Impetus for these storms
appears to be the modest ascent attendant to the weak vorticity
maximum moving northward/northeastward out of central PA. Strong
insolation downstream across central NY has resulted in air mass
destabilization and steep low-level lapse rates. Storm organization
and persistence will likely be mitigated by generally modest
vertical shear, but buoyancy is still be strong enough for updrafts
capable of water loading and isolated strong downbursts.
