Throughout history, extreme temperatures have captured human attention for their dramatic impact on both the environment and society.

In every state, records of the most intense heat or cold serve as benchmarks of nature’s extremes, often reflecting the unique conditions of the region. These temperature milestones are not just meteorological curiosities, they affect agriculture, infrastructure, and daily life.

While these events may be rare, their consequences can be lasting, prompting emergency planning. The dramatic increase in temperature often occurs during extraordinary weather events influenced by global and regional weather patterns. Regardless of what caused them, these record-breaking moments stand out as reminders of Mother Nature's power. Understanding when and how these extremes occur helps us better prepare for future events in an era of ever-changing climate patterns.

"Tropical Storm Agnes unleashed its fury on Pennsylvania in 1972 by claiming the lives of 48 people in the state and causing damages worth a $2 billion. According to the Evening News, the Susquehanna River, which has a normal volume of 23 billion gallons a day, began overflowing rapidly into Harrisburg as its volume increased to 650 billion gallons two days after the state experienced its most torrential downpour."
