Overview
|
June 22nd was a highly unstable day, and became the busiest and most widespread severe weather day of the year so far. A thunderstorm wind gust/squall estimated at 60 mph occurred at the NWS Office in State College. This squall lasted almost 2 minutes, and was accompanied by pea size hail at the office. Numerous large hail reports also came in from many locations in and around the rest of State College. Many trees were downed, as the storms were mainly bow echoes, with occasional rotation present. Numerous reports of large hail also came in from across Central PA. |
 Balloon Sounding from KLWX (Washington DC). See the Positive Area (a.k.a. "B+" or "CAPE") is almost 2800 J/kg! That is Highly Unstable. |
