Warmer than average winter expected?

If you like warmer winters rather than cooler winters, this outlook might make you happy. We are expecting La Nina to develop during the winter months.

La Nina is when an area of water near the equator in the Pacific Ocean becomes colder than normal. This abnormality causes the polar jet stream to not sit where it normally does and that causes weather patterns to differ. Below is where the jet stream sits during La Nina and where it normally sits during an ENSO-neutral year. During an ENSO-neutral year we see typical winter impacts. What that means is colder weather is expected across the north centeral and north eastern US while warmer weather is normally seen in the southern US as well as above normal precipitation.

During a La Nina year, our region usually sees a warmer winter and drier conditions. Below are the NOAA outlooks for months of December, January and February. The Climate Prediction Center is anticipating our region to be warmer than average as well as drier than average for those three months.
