PENNSYLVANIA — A strong cold front is moving into Pennsylvania Friday afternoon and evening, October 16, bringing a line of storms that will sweep quickly from west to east. Ahead of the front, temperatures will climb to 75 to 80 degrees or higher, with dew points of 64 to 69 degrees. That warm, humid air will add to the instability needed for strong storms. Damaging wind gusts are the main threat as the squall line moves through.
Zone 2 Faces the Strongest Storms
The strongest part of the squall line is expected in Zone 2, which covers central and eastern Pennsylvania. That area includes Williamsport, Sunbury, Harrisburg, Lancaster, York, and Gettysburg.
Zone 2 also stretches east to Pottsville, Reading, Allentown, Scranton, Stroudsburg, Norristown, and Philadelphia. The strongest wind shear and instability are expected to overlap here.
Gusts of 45 to 55 MPH, Isolated 60 MPH
In Zone 2, scattered wind gusts of 45 to 55 mph are expected. Isolated gusts of 60 mph or greater are also possible.
These winds could lead to tree damage and a few power outages. Holiday lawn decorations, trash cans, and outdoor furniture should be tied down or brought inside.
Zone 1 Sees Weaker Storms
Zone 1 covers much of central and western Pennsylvania, including State College, Altoona, Johnstown, Clearfield, DuBois, and Coudersport. Areas near Towanda and Wellsboro in the north are also included…
