Tea Cup Size Hail Tonight: Rare In Pennsylvania



Tonight, Pennsylvania saw a rare weather phenomenon. Hail 3.00” in diameter or the size of “tea cups”. According to the National Climatic Data Center, since 1950 (when records were first kept by them), there was only 11 previous reports on file of 3.00” diameter hail or larger. Tonight, there were three reports of 3.00” diameter hail in Carbon County, Pennsylvania.

The largest hailstone to ever occur in Pennsylvania was back 1956 in Beaver County when 4.50” hail was reported. There are three reports of 4.00” diameter hail on file which were received in 1980 and 2010. There is also one report of 3.80” diameter hail that was received in 1994. The other 6 of 11 were 3.00” hail reports which were reported in 1960, 1967, 1974, 1983, 1996, and 2010.

Tonight’s reports occurred in Summit Hill around 7:06 p.m. Two reports were received in the community of Lansford around 7:06 p.m. and 7:10 p.m.

Of course, hail was not the only problem this evening. Damaging wind gusts caused numerous trees and power lines to come down in parts of the Lehigh Valley and the Poconos. Whether any brief tornado occurred within the swath of damaging winds will be considered by the National Weather Service if any reports of significant damage are received.

Tens of thousands have been left in the dark from Southwestern Pennsylvania into Southern New York by the large hail and damaging winds…and even a few suspected tornadoes that we know of in Central Pennsylvania.
