Strong Thunderstorm & Gusty Winds in Poughkeepsie NY, June 6, 2024

On June 6th, 2024, a large stacked cyclone was in place over Ontario Canada with a negatively tilted trough extending southeastward from this feature over the Great Lakes. In southern NY, a warm front passed through the area early in the morning, followed by a cold front during the evening. Within the warm sector ahead of the cold front mild to moderate instability and forcing from the approaching front allowed a broken line of thunderstorms to develop over central NY before traveling eastward into the Hudson Valley. While speed shear (or increase in winds with height) was not particularly high, there was a decent amount of directional shear with height. Winds at the surface were out of the south with these winds veering to westerly by a altitude of 3 km. These wind profiles favored cyclonic updraft rotation and transient supercell characteristics within the valley.
I intercepted one of these cells right next to Shadows on the Hudson in Poughkeepsie around 5pm local time. Heavy rain ahead of the updraft made viewing the storm structure difficult, but the storm did produce some nice cloud to ground lightning bolts along with sub-severe wind gusts estimated to be around 40 mph .
