A surge of tropical moisture at the end of September dumped heavy rain on saturated Plains soils, triggering flooding concerns, washing out roads in parts of Kansas and slowing fall harvest — while simultaneously rebuilding soil moisture for stressed winter wheat and pastures.

The downpours capped a month that brought several needed batches of rain to parts of the Plains. Some of that moisture arrived with thunderstorm activity, including severe storms that struck portions of the region.

For growers, the trade-off is direct: flooded fields and washed-out roads delay combines and grain movement, but the moisture banked in the soil profile positions drought-stressed winter wheat and grazing land better heading into fall and winter.

Where did the heat set records?

While the northern and central Plains cycled between warm and cooler days in September, Texas heat stood out. McAllen recorded a stretch of 100-plus-degree days that began in late July and was still running through September, including record highs of 103 degrees Fahrenheit on both September 20 and 21.

Other Texas cities posted records in the same window:

• Waco soared to a record 101 degrees on September 20.
• Tyler hit a record 100 degrees on September 22.
• Houston notched a record 99 degrees on September 23.

The persistence of triple-digit heat into late September adds pressure on late-season crop water demand, livestock heat stress and irrigation costs in South Texas.

How strong is El Niño, and why does it matter?

Globally, El Niño is strengthening, and forecasters expect a very strong event this fall and winter. Some forecasts even show the likelihood of a historically strong El Niño — a designation measured against records dating back to 1950.

For Plains producers, El Niño winters typically shift precipitation patterns, and the outlook already reflects that: the December forecast keeps above-normal temperatures in place for Nebraska and northern Kansas, while precipitation over the next three months should run above seasonal norms across the southern and central Plains.

What does the October outlook show?

The October forecast splits the region:

• Above-normal precipitation is expected for the Southern Plains.
• The northern half of Nebraska should see below-normal precipitation.
• Above-average temperatures are forecast for southern Texas, Nebraska and much of Kansas.

The temperature signal extends beyond a single month. Forecasters expect above-normal temperatures to continue through December for Nebraska and northern Kansas, while precipitation over the next three months should stay above seasonal norms for the southern and central Plains.

For winter wheat growers, the setup cuts both ways. Ample soil moisture from late-September rains plus a wet-leaning three-month outlook supports stand establishment in the southern and central Plains. But sustained above-normal temperatures across Nebraska and northern Kansas can push fall growth, affect vernalization timing and raise the risk that tender growth takes a harder hit when cold air finally arrives.

Separating condition reports from forecasts

The September flooding, harvest delays and record heat are observed, harvested-conditions-style facts. The El Niño intensity and the October-through-December precipitation and temperature patterns are forecasts — outlooks that carry uncertainty and can shift as the event develops. Producers weighing input purchases, wheat planting decisions and grazing plans should track monthly updates rather than anchoring on a single seasonal map.
