Weather Roller Coaster: Unusual August Temperatures Bring Hazy Sunday and Summer Heat

Cooler temperatures are expected to creep into the Lehigh Valley after a brief return to heat and humidity. A cold front will move through the area, followed by Canadian high pressure, resulting in below-average temperatures through the end of the month. The upcoming pattern of cooler temperatures is described as "a little unorthodox for this point in August." However, the influence of tropical disturbances in the Atlantic could potentially impact the weather pattern.
