Valid 272306Z - 280030Z The severe weather threat for Severe Thunderstorm Watch 631 continues. SUMMARY...Isolated damaging winds and a conditional brief tornado threat will continue into early evening. Storms will gradually weaken east of the Hudson Valley. No additional watches are expected. DISCUSSION...Over the last 2 hours, marginal supercell structures have generally evolved into small linear segments. The impacts of a less unstable airmass to the east and outflow from the south have likely contributed to a modest decrease in storm organization. The strongest activity in the Hudson Valley vicinity will still be capable of isolated wind damage into early evening. A brief tornado remains possible given some SRH enhancement on the KENX VAD, though low-level thermodynamics have limited mesocyclone intensity late this afternoon. With time, a gradual weakening trends is likely to be observed as storms move into southern New England. Additional watches are not expected this evening. ..Wendt.. 08/27/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BOX...BTV...OKX...ALY...BGM...
