MD 1372 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR CENTRAL PA INTO PORTIONS OF UPSTATE NY
Mesoscale Discussion 1372
NWS Storm Prediction Center Norman OK
1254 PM CDT Sat Jul 01 2023
Areas affected...central PA into portions of Upstate NY
Concerning...Severe potential...Watch unlikely
Valid 011754Z - 012000Z
Probability of Watch Issuance...20 percent
SUMMARY...Thunderstorm clusters may produce locally strong gusts
through the afternoon.
DISCUSSION...Thunderstorm activity is expected to gradually increase
in intensity and coverage through the afternoon as convection
develops within broad large-scale ascent downstream from a Canadian
midlevel trough. Vertical shear remains weak over the region, but is
forecast to gradually increase, with effective shear magnitudes
around 25 kt by late afternoon. A moist boundary-layer with
dewpoints in the upper 60s to low 70s F is contributing to modest
destabilization (1000-1500 J/kg) across the region. This parameter
space should support briefly organized cells/clusters and sporadic
strong gusts will be possible as convection spreads east/northeast
through the afternoon/early evening. The overall severe thunderstorm
risk is expected to remain modest, and a severe thunderstorm watch
is not currently expected.
