NWS Storm Prediction Center Norman OK
1039 AM CDT Sat May 25 2024
Areas affected...portions of eastern Ohio into western Pennsylvania
and far southwest New York
Concerning...Severe potential...Watch unlikely
Valid 251539Z - 251815Z
Probability of Watch Issuance...20 percent
SUMMARY...Thunderstorms should increase in coverage and intensity
through the afternoon. Damaging gusts and some hail may accompany
the strongest storms. The severe threat should be isolated and a WW
issuance is not currently anticipated.
DISCUSSION...Thunderstorms are gradually increasing in coverage and
intensity ahead of a surface trough over eastern OH, with agitated
CU becoming apparent ahead of the storms. Strong diurnal heating and
modest warm-air/moisture advection amid modest lapse rates is
boosting MLCAPE to 1500 J/kg via tall, thin vertical profiles (per
latest RAP forecast soundings). These forecast soundings also depict
small low-level hodographs, but with mid-level elongation. As such,
stronger multicell clusters and line segments that can become
established may contain hail (with a couple bouts of severe hail
possible). Damaging gusts may also occur with the stronger storm
cores. The severe threat should remain isolated though, so a WW
issuance is not expected.
