U.S. Winter Outlook: Wetter South, Warmer North

Planners Should Take Note of Weather Pattern Predictions

As we move into the fall/winter meetings and events season, the weather can become increasingly unpredictable. This can negatively impact meetings and events in a number of ways. Weather events can cause flight delays or cancellations that can disrupt the agenda of a meeting or event. They can also create safety hazards for attendees and staff and of course damage hotels and venues to the point where they can no longer host meetings.

Here is a rundown of what weather meeting planners can expect around the country this year.

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 National Oceanic Atmospheric Administration’s (NOAA) U.S. Winter Outlook just released 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, Ph.D., 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 (NIDIS), continue to monitor extreme, ongoing drought conditions that have persisted through the southern and central U.S. and worsening drought in Hawaii. Earlier this year, drought resulted in catastrophic wild fires on Maui, though the island has recently reopened for groups.

“According to the Oct. 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.”

Temperature

  • 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.

Precipitation

  • 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.

Drought

  • 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. 

NOAA’s seasonal outlooks provide the likelihood that temperatures and total precipitation amounts will be above-, near- or below-average, and how drought conditions are anticipated to change in the months ahead. The outlook does not project seasonal snowfall accumulations as snow forecasts are generally not predictable more than a week in advance.

NOAA’s Climate Prediction Center updates the three-month outlook each month. The next update will be available November 16.

Seasonal outlooks help communities prepare for what is likely to come in the months ahead and minimize weather’s impacts on lives and livelihoods. Resources such as drought.gov and climate.gov provide comprehensive tools to better understand and plan for climate-driven hazards. Empowering people with actionable forecasts, seasonal predictions and winter weather safety tips is key to NOAA’s effort to build a more Weather- and Climate-Ready Nation.

Help Attendees Beat the Heat

A blistering heat wave has gripped the Western United States, leaving a trail of suspected heat-related deaths and shattering temperature records. To ensure attendee health and safety during a heat wave at trade shows and conferences, planners should implement the following measures.
