Forecasters at the National Oceanic and Atmospheric Administration believe there is a 75 percent chance that La Niña will stick around through the winter, which will play a significant role in who will see snow and which communities will need to keep their gear in storage for another year.
Historical data shows how strong a La Niña is and can determine which parts of the country will be subject to abnormal weather conditions.
The state of a La Niña is determined by sea surface temperature anomalies in the central and eastern Pacific.
A moderate La Niña has anomalies that range from -1.0 °C to -1.4 °C, and when water temperatures are at least -1.5 °C below normal, a La Niña is considered to be strong.
Depending on whether the La Niña is weak, moderate or strong will have a dramatic effect on snow accumulations, freezing temperatures and all other aspects that accompany Old Man Winter.
Climate forecast models indicate the 2022-23 La Niña will likely stay in the range of either being weak or moderate through the country’s winter.
