How Long Will It Stay Warm? Long Range Forecast Is Mild

1 Nov 2016, 8:59 am

October was a warm month in most of the country and the mild temperatures are expected to last for a little while longer. The 90 day forecast from the National Weather Service’s Climate Prediction Center covering November, December, and January has the thermometer staying above normal from the East Coast through the Deep South into the Southwest. Temperatures are forecast to trend closer to average across the rest of the nation.

Drier than normal weather will continue across most of the Southern U.S.  A slowly developing La Nina event, which is expected to become more evident over the next several months, is the reason for the dry forecast across the south. The Climate Prediction Center has reissued a La Nina Watch for the upcoming months. During La Nina periods, the Jet Stream is less active in the Southern U.S. This usually leads to less storms systems and below average precipitation. La Nina occurs when the waters of the Pacific Ocean show a general trend of cooling, which is the opposite of an El Nino. Above average precipitation is forecast for the Northern Rockies into Montana.

The La Nina event is expected to strengthen into 2017, which is forecast to bring colder than normal conditions into the deeper Winter months across the Northern Tier of the country. Wetter than normal weather is forecast as well in the north, due in part to a more active Jet Stream in this area during a typical La Nina. This could lead to above average snowfall from the Great Lakes into the Pacific Northwest. The Climate Prediction Center Winter Outlook, covering December, January, and February, expects the warm and dry conditions to continue in the South.

The next long range forecast update from the Climate Prediction Center will be in the middle of November.
