WEATHER UPDATE historical maximum amount of moisture, parts of the West would still be in drought after this El Niño ends. That is an important point. We can have a substantially wet season without solving the water shortage.
For producers, the timing matters as much as the total rainfall. Obviously, moisture arriving during winter can help recharge soils, but rainfall extending into spring is particularly valuable for pasture growth and the beginning of the growing season. The opportunity is there. The question is whether, and for how long, the favorable pattern lasts through 2027. There is another factor worth watching El Niño gets most of the attention, but it is not the only ocean pattern with a strong influence. The Pacific and Atlantic oceans experience temperature shifts that can last for decades. These longer cycles affect atmospheric patterns, and this helps explain why some decades experience more frequent drought while others are generally wetter.
The Pacific Decadal Oscillation, a longer-lasting pattern of ocean temperatures in the North Pacific, is one of the factors I am watching closely, and one of the offsetting factors alluded to above. Its current configuration may offset the typical El Niño pattern, especially across the Central and Southern Plains- meaning, not as wet as expected.
That does not mean El Niño will fail. It means the atmosphere is responding to several influences at once, and they do not always work together, so we cannot simply compare this event to any other. This helps explain why two El Niños of similar strength can produce very different winters. What happens next? The outlook through winter and into spring favors meaningful drought improvement across portions of the southern United States. The Southwest and Southern Plains have some of the better opportunities. The outlook is less encouraging for the Pacific Northwest and Northern Rockies, where El Niño has historically provided less frequent moisture.
And there is another concern beyond next spring. Many of the strongest El Niño events eventually transition toward La Niña, the cooler counterpart to El Niño, by the following winter. La Niña often favors drier conditions across portions of the southern United States and is the pattern we have been in six of the last seven winters. If that transition does indeed come later in 2027, the opportunity for sustained drought recovery could become shorter than many would like.
For now, the message is that we have a legitimate opportunity to improve drought conditions over the coming months, potentially substantially in some regions. But the longer-term drought problem will not disappear entirely despite headlines calling for a“ Super El Niño.”
The best approach is to take advantage of moisture when it arrives while recognizing that total recovery may take more than one season.
