Heatwaves across the US and mild and muggy nights continue to dominate the dog days of summer. However, the Northern Hemisphere is heading towards the fall season, and a shift in the weather is expected soon.
The autumnal equinox begins on September 22 this year and marks the beginning of autumn. The season will see more than just a shift in weather. It will instead witness a range of fall festivals — from leaf-peeping to football. But those who wish to engage in outdoor fall activities must be careful. The weather could suddenly change from pleasant to damp and drizzly. Thus, it is important to check the expected overall weather patterns when heading out.
Forecasters have been conducting analyses of ongoing weather patterns by looking at various computer models. They come up with a seasonal outlook on the basis of past observations. So, insights into the expected trends between September and November are provided.
The climate phenomenon La Niña is emerging as one of the bigger factors that will impact the United States as a whole this autumn. The event takes place when the waters close to the equator of the Pacific Ocean are abnormally cool. It modifies the weather patterns thousands of miles away, including across the country. This is the second consequent autumn that La Niña has influenced.
Paul Pastelok, AccuWeather Senior Meteorologist, stated that although we usually see La Niña occur between the late fall and the winter season, this year it seems as though it will arrive early just like it did in 2020.
La Niña’s return is a signal of not just other high-impact weather events across the country but also that of another above-average hurricane season. And although meteorological autumn starts on September 1, residents from Boston to Chicago may not witness fall-like weather immediately.
