Warmer and drier weather expected in Louisiana this winter

NOAA Winter Outlook 2017-2018

Forecasters at NOAA's Climate Prediction Center said Thursday the odds are greater than average for La Niña conditions, which in the Pacific Northwest means a cooler, wetter winter.

Scientists from NOAA's Climate Prediction Center said there is a 55 percent to 65 percent chance of La Nina weather conditions developing before winter begins - the second straight La Nina winter.

NOAA says that one of the biggest factors this winter will be the emergence of La Nina, a cooling of the waters in the Pacific Ocean off of South America.

Warmer-than-normal conditions are most likely across the southern two-thirds of the continental USA and along the East Coast, including North Carolina, as well as across Hawaii and in western and northern Alaska.

The average winter temperature at Long Island MacArthur Airport is 33.1 degrees, with an average of 10.96 inches of precipitation, which includes melted snow, according to Jessica Spaccio, climatologist with the Northeast Regional Climate Center at Cornell University.

NOAA is predicting warmer-than-normal temperatures across the southern two-thirds of the continental U.S., East Coast, Hawaii, and Western and Northern Alaska. The rest of the country, including Chicago, falls into the "equal chance" category, which means they have an equal chance for above-, near-, or below-normal temperatures.

For the United States, La Nina would reduce precipitation across much of the South, with limited increases in the far north.

Winter Outlook and the weather lies in the hands of a possible La Nina.

Keim says the last few weeks of dry and warm weather are a precursor of this coming winter according to NOAA.

Pastelok expects Arctic blasts to freeze the northern Plains this winter with temperatures sinking to subzero levels on a regular basis.

Drier-than-normal conditions are most likely across the entire southern U.S. However, it won't spell bad news for ski season, as ski resorts will receive enough snowfall to create good conditions, but not so much that people struggle to get to them, he said.
