The 2023-2024 U.S. Winter Outlook map for precipitation shows wetter-than-average conditions are most likely across the South and Southeast and parts of California and Nevada. Drier-than-average conditions are forecast for parts of the northern tier of the United States.

This year, El Nino is in place heading into winter for the first time in four years, driving the outlook for warmer-than-average temperatures for the northern tier of the continental United States, according to NOAA’s U.S. Winter Outlook released today by the Climate Prediction Center — a division of the National Weather Service. 

“These outlooks provide critical guidance on the upcoming season for many industries and sectors of our economy, from energy producers to commodities markets to agricultural interests to tourism,” said Sarah Kapnick, NOAA chief scientist. “With a strengthening El Nino and more potential climate extremes in an already record-breaking year, we’re lucky to have scientists like those at the Climate Prediction Center helping to build a Weather and Climate-Ready Nation by providing critical operational seasonal climate predictions.”
From December through February, NOAA predicts wetter-than-average conditions for northern Alaska, portions of the West, the southern Plains, Southeast, Gulf Coast and lower mid-Atlantic and drier-than-average conditions across the northern tier of the U.S., especially in the northern Rockies and High Plains and near the Great Lakes.

“An enhanced southern jet stream and associated moisture often present during strong El Nino events supports high odds for above-average precipitation for the Gulf Coast, lower Mississippi Valley and Southeast states this winter,” said Jon Gottschalck, chief of the Operational Prediction Branch of the Climate Prediction Center.

NOAA forecasters, in collaboration with the National Integrated Drought Information System continue to monitor extreme, ongoing drought conditions that have persisted through the southern and central U.S. and worsening drought in Hawaii.

“According to the October 17 U.S. Drought Monitor, a third of the country, including Puerto Rico, is in drought,” said Brad Pugh, operational drought lead with NOAA’s Climate Prediction Center. “During late October, heavy precipitation is likely to result in drought improvement for the central U.S. El Nino with its enhanced precipitation is expected to provide drought relief to the southern U.S. during the next few months.”

The 2023-2024 U.S. Winter Outlook map for temperature shows the greatest chances for warmer-than-average conditions are in the northern tier of the continental United States. Warmer-than-average temperatures are favored across the northern tier of the U.S. and much of the Far West.

The greatest odds for warmer-than-average conditions are in Alaska, the Pacific Northwest and northern New England.

Near-normal seasonal mean temperatures are most likely for a region from the south-central Rockies to the southern Plains.

Remaining areas fall into the category of equal chances for below, near, or above-average seasonal mean temperatures.
Wetter-than-average conditions are most likely in northern Alaska, some areas of the West from parts of California to the south-central Rockies, the southern Plains, Gulf Coast, Southeast and lower mid-Atlantic. 

The greatest odds for drier-than-average conditions are forecast in portions of the northern Rockies and central Great Lakes region, especially for Michigan and northern Ohio and Indiana.

Much of the central portion of the U.S. falls into the category of equal chances for below, near, or above-average seasonal total precipitation.
The U.S. Drought Outlook map for November 2023 through January 2024 predicts drought improvement in the South, lower Mississippi Valley, Texas and parts of the Midwest. 

Drought is likely to persist in portions of the desert Southwest, in parts of the Pacific Northwest eastward along the northern tier to the Great Lakes, and across Hawaii. Drought development is expected in the interior Pacific Northwest. 

Widespread extreme to exceptional drought continues to persist across much of the South, and portions of the central U.S.

Drought conditions are expected to improve across the Southeast, the Gulf Coast (including the lower Mississippi Valley), and Texas due to the expected wetter-than-average forecast.

Drought conditions are expected to persist for the northern Rockies, northern Great Plains, and portions of the desert Southwest this winter.

Drought development could occur in the interior Pacific Northwest given the chance for drier-than-average conditions.

Drought is likely to persist or develop across Hawaii.
