An additional EF-0 tornado was confirmed from last week's storms on August 20. We have the latest report in the article below.
MOUNTVILLE, Pa. —
The National Weather Service in State College, Pa., has just confirmed another EF-0 tornado that touched down on the evening of Aug. 20, 2026.
Above: Today's forecast from the WGAL News 8 Storm Team.
According to a survey conducted with assistance from Millersville University students, the tornado formed at 4:37 p.m. northwest of Habecker Church Road and tracked south-southeast through several cornfields, producing a narrow path of damage.
Peak winds were estimated at 65 mph, with the tornado carving a path about 0.3 miles long and up to 75 yards wide at its maximum extent.
Survey teams noted the tornado began to dissipate as it crossed Habecker Church Road, where the damage path briefly widened and grew less defined.
Investigators also found evidence suggesting a second, narrower vortex developed east of the main circulation and merged with it near the road crossing, which can typically happen with evolving tornadoes.
The tornado appears to have lifted before cycling (or reforming) again, producing additional damage to the northeast as it moved into a residential area.
No injuries or fatalities were reported.
The tornado marks the fourth confirmed in the Susquehanna Valley on Aug. 20. The other three happened in:
The National Weather Service extended thanks to Millersville University students who assisted with the ground survey.

Survey Summary:
A brief EF-0 tornado occurred at 4:37PM EDT on August 20, 2026.
The tornado began northwest of Habecker Church Rd and carved out a
narrow convergent swath of damage in several cornfields as it
moved south-southeast. The tornado began to occlude as it crossed
Habecker Church Rd, after which the path briefly widened and
became a bit less defined. Interestingly, there may have been a
second even more narrow vortex that developed to the east of the
parent vortex (to the left from a storm-relative standpoint) and
joined up with the main circulation near Habecker Church Rd. The
tornado likely lifted as it cycled and subsequently produced more
damage to the northeast as it crossed a residential area.
We would like to thank students from Millersville University for
their assistance in this damage survey.
