Strong El Niño Expected to Influence North American Winter Weather

Why it matters locally: A strong El Niño typically leads to warmer and drier winters in the northern United States, which could impact Pennsylvania's winter tourism and agricultural sectors.

Climatologists forecast a strong phase of the El Niño climate pattern, commonly referred to as a 'Super El Niño,' to significantly influence winter weather across North America. This pattern typically intensifies during the winter months, altering both precipitation and temperature across the region. Researchers predict this strong El Niño will increase the probability of winter precipitation throughout the Southern United States. The pattern also impacts hurricane season activity. Forecasters have identified several states as susceptible to considerable snowfall and extreme weather occurrences during the upcoming winter season.
