Forecasters are watching a developing “super” El Niño in the equatorial Pacific and assessing what it means for Wyoming’s winter weather. Cheyenne National Weather Service meteorologist Mike Natoli says the pattern will likely bring reduced wind speeds statewide and a split in precipitation.
What the forecast means for Wyoming
Between now and late spring, the southern half of the state can expect higher‑than‑average precipitation, while the northern and especially the northwest corner should see below‑average snowfall. Natoli notes that even the northern areas may fare better than last winter’s historically sparse snowpack.
The jet stream is expected to shift further south, pulling storm systems up from Colorado. Those storms typically dump more snow on the eastern slopes of the mountains than on the western faces, which could benefit ski areas such as Hogadon on Casper Mountain, the Snowy Range west of Laramie, and Pine Creek near Cokeville.
Potential relief for drought‑stricken basins
Improved snowfall and rain could aid the North Platte River Basin in southern Carbon County and the Laramie River Basin in the far southeast, both of which suffered some of the worst conditions last year. Natoli expressed cautious optimism that these basins may see modest improvement.
Overall, the most reliable El Niño impact for Wyoming this winter is a slight reduction in wind speed. While the state will remain windy by its standards, residents may notice a calmer atmosphere compared with the previous year.
Understanding the “super” label
NOAA describes this El Niño as one of the strongest on record, with sea‑surface temperatures already 5.4 °F above average. Climate experts warn that human‑caused warming is amplifying the event, potentially shifting rainfall and temperature patterns worldwide.
Natoli cautions that the intensity adds uncertainty: “The strength of this El Niño may be surpassing any we have observed in the past, which could cause some unexpected things.” Nonetheless, the forecast suggests a mix of relief and continued challenges for Wyoming’s agriculture and recreation sectors.
