853 ACUS11 KWNS 142221 SWOMCD SPC MCD 142220 NJZ000-NYZ000-PAZ000-142345- Mesoscale Discussion 1263 NWS Storm Prediction Center Norman OK 0520 PM CDT Fri Jun 14 2024 Areas affected...Middle Atlantic Concerning...Severe Thunderstorm Watch 415... Valid 142220Z - 142345Z The severe weather threat for Severe Thunderstorm Watch 415 continues. SUMMARY...Locally damaging winds and marginally severe hail are expected with convection early this evening. DISCUSSION...Weak mid-level short-wave trough is ejecting across the Middle Atlantic early this evening. This feature appears to be aiding a broad corridor of convection that extends from the lower Hudson Valley, arcing southwest across central NJ where convection has recently intensified, possibly due to coastal boundary interactions. Surface temperatures are seasonally warm ahead of this activity, even near the coast where readings remain in the 80s. Modest buoyancy extends across the Delmarva into southern New England and this will contribute to new updrafts forming along the leading outflow as the aforementioned complex advances east this evening. Locally damaging winds are the primary risk along with marginally severe hail. ..Darrow.. 06/14/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OKX...PHI...BGM...
