FORT WAYNE, Ind. (WFFT) — A La Niña watch has been issued for our upcoming winter in the Northern Hemisphere.
Currently, ENSO-neutral conditions are occurring along the equator in the Pacific.
That means that sea surface temperatures are about average along South America and central Pacific ocean.
Below-average temperatures are normal along Australia.
These conditions are forecasted to continue through the summer by the Climate Prediction Center, National Centers for Environmental Prediction and the National Weather Service.
You can read more about the forecast here.
However, changes are forecasted for the fall and winter of 2020.
There's a 50 to 55% chance that La Niña will develop by the end of the year.
A La Niña Watch means that conditions are favorable for this to occur in the next 6 months.
La Niña conditions happen when sea surface temperatures are 0.5 degrees Celsius cooler than average in South America.
The La Niña pattern happens every 3 to 5 years.
But this ocean pattern affects the weather patterns across the globe.
In northeast Indiana and northwest Ohio, we actually see a change in our weather here.
During the fall, we see warmer and drier conditions.
The winter tends to be wetter than normal.
Some years, we see colder than average temperatures and other years we see warmer than average temperatures.
