NWS Storm Prediction Center Norman OK
0650 PM CDT Mon Jun 17 2024
Areas affected...central Pennsylvania
Concerning...Severe potential...Watch unlikely
Valid 172350Z - 180045Z
Probability of Watch Issuance...5 percent
SUMMARY...Thunderstorms with the potential for strong to severe wind
will persist across central Pennsylvania.
DISCUSSION...A line of thunderstorms has developed along a remnant
outflow boundary across central PA. Ahead of this line of storms,
temperatures are in the mid 80s to 90s with mid to upper 60s
dewpoints. The downstream air mass is further characterized by
MLCAPE around 500-1000 J/kg and steep low-level lapse rates. Weaker
mid-level lapse rates are noted along with generally weak flow
aloft. Nonetheless, this environment will support instances of
strong to severe wind over the next couple of hours, should this
line maintain intensity and progress eastward.
