NWS Storm Prediction Center Norman OK
0833 PM CDT Thu Aug 24 2023
Areas affected…Northern Indiana…Northern Ohio…western
Pennsylvania…western New York
Concerning…Severe potential…Severe Thunderstorm Watch likely
Valid 250133Z – 250300Z
Probability of Watch Issuance…80 percent
SUMMARY…A Severe Thunderstorm Watch downstream of WW656 is likely
shortly.
DISCUSSION…A broken line of severe storms continues to move
southward out of Michigan and across Lake Erie. Consensus within
hi-res guidance is for this line to continue to track southward into
portions of northern Indiana, northern Ohio, western Pennsylvania,
western New York within the next couple of hours. Downstream of this
line, there is a gradient of MLCAPE around 1500-3500 J/kg and deep
layer shear 35-45 kts. The environment will continue to be
supportive of severe storms and risk of damaging winds along with
isolated embedded circulations and a tornado or two. A downstream
watch will be needed shortly.
