Survey Summary:
A team from the National Weather Service in Pittsburgh identified
a coherent swath of likely tornadic damage that began along
Stanton Ave in the Highland Park neighborhood of Pittsburgh and
continued to along Campania Ave in the Lincoln-Lemington-Belmar
area. Damage was sporadic along this path, suggesting the
circulation occasionally weakened below tornadic intensity along
this track, possibly owing to variability in terrain. The most
concentrated damage was observed along Lemington Ave, where a
couple trees were down, small and large limbs were snapped, and
shingles were removed from homes. There is no evidence that
power poles in this area were damaged by wind, which puts an
effective upper bound on wind speed estimates here. Debris lofted
by the tornado (likely leaves and small twigs) was noted in data
from KPBZ radar, which continued in the air downstream for
several miles as strong, non-tornadic wind surged eastward into
the Penn Hills area. This narrow tornado was embedded within a
broader swath of 40-60 mph non-tornadic wind, as evidenced by
threshold tree litter. Pending additional information, this
tornado will be rated EF0 with maximal wind of 70 mph.
