Mesoscale Discussion 1640 NWS Storm Prediction Center Norman OK 0654 PM CDT Mon Jul 15 2024 Areas affected...Central New York and Northeast Pennsylvania Concerning...Severe Thunderstorm Watch 540... Valid 152354Z - 160130Z The severe weather threat for Severe Thunderstorm Watch 540 continues. SUMMARY...The environment remains conducive for severe thunderstorms across central New York and northeast Pennsylvania to persist for another couple of hours. Wind will be the most common threat. DISCUSSION...Two quasi-linear bowing segments are ongoing across the severe thunderstorm watch: one in northeast Pennsylvania and another in central New York. Both of these bowing segments are moving east-northeast within an unstable airmass (CAPE around 1000 J/kg) and have a history of producing wind damage. Despite deep-layer shear decreasing with eastward extent, the organized nature of the convection will allow a wind damage threat to persist for another couple of hours. ..Marsh.. 07/15/2024 ...Please see www.spc.noaa.gov for graphic product...
