The National Weather Service has issued a Severe Thunderstorm Watch until 8PM for the Lehigh Valley. Please keep your eyes to the sky.
According to the National Weather Service, a Severe Thunderstorm is:
A thunderstorm that produces either of the following: winds of 50 kts (58 mph) or greater (these speeds can result in structural or tree damage), hail ¾" in diameter or larger, or a tornado. Lightning frequency is not a warning criteria for issuing a severe thunderstorm warning. Severe thunderstorms can result in the loss of life and property. They can also produce a tornado with little or no advanced warning. A table of hail sizes can be found in this glossary, under the definition of hail.
