Strong T-Storms In CNY Could Contain Supercells With Large Hail And Damaging Winds
The National Weather Service says we could see some powerful storms roll through Central New York this afternoon and evening and an isolated tornado cannot totally be ruled out.
Hazardous Weather Outlook issued from the National Weather Service out of Binghamton at 306 PM EDT Wed Apr 28, 2021, for the following locations.
...ISOLATED SEVERE THUNDERSTORMS POSSIBLE LATE TODAY...
Severe storms are possible in Northern Oneida, Seneca, Southern Cayuga, Onondaga, Tompkins, Madison, Southern Oneida, Cortland, Chenango, Otsego, Tioga, Broome, Delaware, Sullivan, and Susquehanna counties.
A line of showers and thunderstorms have developed across western NY and moves through the region from late afternoon into the early evening. A few of the thunderstorms may become severe with damaging winds and perhaps some hail.
The National Weather Service says:
The instability, forcing, and especially the wind speed will offer a decent environment for upstream convection to carry into our region. With the 6km level exceeding 50 knots, storm mode may include supercells with large hail and damaging wind gusts. Perhaps even an isolated tornado cannot totally be ruled out especially towards southern Finger Lakes/western Twin Tiers, but primary threat will be for damaging wind gusts, with speed shear dominant and directional shear limited..
There will be a batch of convection roughly 4-9PM for Central NY to near PA border, but a second attempt may be made 9PM-midnight.
