On February 11, 1887, at least 6 tornadoes ripped across the state of Pennsylvania during this rare February outbreak.  Since 1950 only 6 other tornadoes have occurred in the state of PA in the month of February. 

The Weather Bureau’s Monthly Weather Review (MWR) reported 17 tornadoes across Parts of Indiana, Ohio, Pennsylvania, New York, and Maryland this day.  Thomas Grazulis only lists one Ohio tornado and one Indiana Tornado in Significant Tornadoes.  The focus of this Funnel Feature will be on the Pennsylvania Tornadoes. Those are the ones I have done the most research into while working on the Central Pennsylvania Tornado Database.  

The tornadoes were spawned between 11am and Noon and were probably embedded in a Quasi Linear Convective System (QLCS).  In other words, these were twisters embedded within a squall line.  One of these tornadoes, the Tyrone Tornado, unfortunately, proved to be deadly, killing 5 Hungarian immigrants.  This is an interesting event to look into because details on some of these tornadoes aren’t available as the newspapers only paid attention to the more significant tornadoes.   

Due to lack of details, 3 of these tornadoes cannot be rated, although it is likely the Mercer and Tionesta tornadoes were likely Significant (F2 or stronger).  

Neshannock, PA to Mercer PA

Rating: F-Unknown Path Length: 9 Miles Path Width: 880 yds Fatalities: 0 Injuries: 0 County: Mercer

Per the MWR this tornado struck at 11am and moved from Neshannock to Mercer.  It was described as “Very Destructive” but since no real damage description was given and cannot be found in the newspapers, a rating can’t be applied.

Tionesta, PA

Rating: F-Unknown
Path Length: 6.5 Miles
Path Width: 880 yds
Fatalities: 0
Injuries: 0
County: Forest

Per the MWR this tornado also hit at 1100 AM and was described as “very destructive” and “the worst storm since 1851”.  As with the Mercer County tornado, since no real damage description was given and cannot be found in the newspapers, a rating can’t be applied. The path plotted here is based on Finley’s Pennsylvania Tornadoes 1811-1888.  

Greensburg, PA

Rating: F2 (minimal)
Path Length: 3 Miles
Path Width: Not known
Fatalities: 0
Injuries: 0
County: Westmoreland

Per the Monthly Weather Review, the tornado occurred around 11:00 although newspapers say it occurred between 10:30 am and 11:00 am. It was “Very destructive”.  Additional Details from newspapers.

  • The tornado tore part of the roof off the new Lutheran Church.
  • Windows were blown out of the courthouse. 
  • The new jail smokestack was cracked for at least 20 feet from the base, and houses were unroofed. 
  • Trees were blown down and fences were “carried away”. 
  • The reports of a derrick being blown over at the Sisters of Charity Farm (on the NW edge of town near present-day Seton Hill University) was likely caused by straight-line winds. 

The path plotted here is just a best guess, and it may have been longer.
