Four Texas cities set record highs in a single three-day span in late September, capping a month that delivered both desperately needed moisture and flooding rain across the Plains. McAllen, Waco, Tyler and Houston all logged new temperature marks between September 20 and 23, while a surge of tropical moisture at month's end pushed saturated soils over their limit and washed out roads in parts of Kansas.

The rain itself cut two ways. Parts of the Plains had spent months waiting for meaningful precipitation, and September finally delivered it in batches. But the closing surge arrived too fast on ground that could no longer absorb it, turning a moisture blessing into a flooding risk and slowing some fall harvest operations.

For winter wheat growers and ranchers, the trade-off still leans positive. The same storms that stalled combines recharged soil moisture profiles in areas where dryland wheat and pasture had been under stress. That moisture matters most now: wheat going into tillering with a full profile faces winter on far better terms than wheat entering dormancy drought-stressed.

Where did the heat records fall?

McAllen, Texas, carried the most remarkable statistic of the month. Its streak of days at or above 100°F began in late July and was still running through the end of September — a stretch approaching ten weeks of triple-digit heat.

The other records landed in quick succession:

• McAllen hit 103°F on both September 20 and 21, setting records on consecutive days.
• Waco reached 101°F on September 20, a record for the date.
• Tyler recorded 100°F on September 22, another daily record.
• Houston notched a record high of 99°F on September 23.

The heat did not dominate the entire region — September mixed warm days with cooler ones across the Plains — but the intensity and persistence of the South Texas warmth stood out against that variability. Some of the month's rain arrived with thunderstorms, including severe storms that impacted parts of the Plains, adding wind and hail risk to the moisture picture.

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

The bigger story for planning purposes sits in the Pacific. El Niño is strengthening, and forecasters now expect a very strong event through this fall and winter. Some forecasts show the likelihood of a historically strong El Niño, in records dating back to 1950.

That framing matters for Plains producers because strong El Niño events historically reshape the region's cold-season precipitation patterns. A wetter southern track and a drier northern tier are the classic signature, and the current outlook tracks that template closely.

What does the October forecast hold?

The near-term outlook splits the Plains neatly in two:

• 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.

Temperature anomalies look persistent. Above-normal readings are forecast to continue through December for Nebraska and northern Kansas, extending the warmth theme well past the record-setting days of September.

On precipitation, the three-month outlook calls for above-seasonal-norm moisture across the southern and central Plains. For wheat country, that points toward a winter of adequate to surplus topsoil moisture — good news for establishment, though it raises the usual watch items around waterlogged fields, disease pressure in thick canopies and delayed spring fieldwork if the pattern holds into the new year.

What should farmers watch next?

Harvest progress is the immediate variable. Operators in areas where heavy rain slowed fieldwork will need drying windows before crops come off, and washed-out roads in parts of Kansas add logistics friction to the harvest queue.

Beyond that, the El Niño trajectory is the number to track. If the event verifies as historically strong, the southern Plains wet pattern could deepen through winter, while Nebraska's northern half may need to manage a dry start to its moisture year. The next monthly update arrives in November, and it will show whether October's forecast precipitation materialised across the wheat belt — and whether McAllen's triple-digit streak has finally broken.
