* At 423 PM EDT, a severe thunderstorm was located near Lockport,
  moving east at 15 mph.

  HAZARD...60 mph wind gusts and quarter size hail.

  SOURCE...Radar indicated.

1.5 “ hail being reported in Lockport. That’s ping pong ball sized hail, about as big as it gets around here. Waiting to see some pics from there.

SUMMARY...An organized cluster of thunderstorms will spread across
   the St. Lawrence River through much of the Adirondacks vicinity,
   along with continuing development across and southeast of Lake
   Ontario by 5-7 PM EDT, accompanied by the risk for potentially
   damaging wind gusts.

   DISCUSSION...Moderate southeasterly low-level inflow of moist air
   characterized by CAPE in excess of 1000 J/kg is maintaining vigorous
   thunderstorm development along the leading edge of an
   east-southeastward advancing, convectively driven surface cold pool.
    This continues to be aided by large-scale forcing for ascent
   associated with a 30-50 kt westerly mid/upper jet streak, and will
   overspread the upper St. Lawrence Valley through much of the
   Adirondacks region by 22-23Z.  As the temperature gradient across
   the gust front increases at least a bit further, potential for
   damaging wind gusts probably will also continue to increase during
   the next hour or two.

   Farther to the southwest, thunderstorms which initiated along the
   trailing outflow boundary, and preceding lake breezes across the
   Lake Ontario vicinity, may also begin to consolidate while spreading
   into the unstable environment to the southeast of the lake.  This
   too may gradually pose increasing risk for damaging wind gusts
   near/north of the Finger Lakes region through the Mohawk Valley by
   early evening.

Yikes!

No severe weather needed...especially in the Mohawk Valley! They've had enough.

Some small rotation on that cell too. Has to be some crazy looking clouds. If I left now I'd probably miss the good stuff.

Nah those storms are back building and training right over Lockport. Gonna be some massive flooding there soon. They get plenty of flooding with a garden variety thunderstorm that last 20 minutes let alone a training storm like this that’s going to last over an hour or two with 2-3” of rain falling an hour.

That storm just went through here with winds that had to be gusting to 50 mph. A few bb sized hail storm also mixed in. I have a couple of small trees in my yard and I thought they were going to snap off.
