TBSS, ProbSevere, In Pennsylvania

Strong isolated thunderstorm developed in northern Pennsylvania with a decent three body scatter spike off the KBUF radar. ProbSevere peaked at 80%, but for wind, with no more than 6% for hail, before the TBSS appeared.

As the TBBS began to appear, ProbWind continued to be the primary key for ProbSevere.

MRMS MESH was less than enthusiastic, with a peak around .40 inches for hail size. Which is a primary driver for the ProbHail.

Sampled from 0.5 to 1.8 degrees, it is possible to see this storm was low-topped, with little vertical extent, but a prominent TBSS through 1.3 degrees.

Here's a loop of the storm, along with the decent response from GLM, which was more robust in coverage than the ENTLN, although flash rates were similar through the course of the storm.
