Conditions will be monitored for the need of a WW issuance pending continued favorable trends for more damaging winds. DISCUSSION...Pulse cells and smaller multicellular clusters are attempting to organize into a loosely organized MCS in far eastern NY. Given the potential for cold pool mergers, preceded by steep low-level lapse rates, it is possible that a more organized damaging gust threat could materialize over the next few hours. 25-35 kts of effective bulk shear (whose vectors are oriented roughly normal to the long-axis of the potential MCS) may also contribute to the organization of an efficient damaging-gust-producing thunderstorm complex. Should further convective organization occur, a WW issuance eventually may be needed. ..Squitieri/Hart.. 06/21/2024 ...Please see www.spc.noaa.gov for graphic product...
