Colorado, Wyoming, Nebraska, Kansas, South Dakota, Texas and Oklahoma Face Historic March Heat Surge as Expanding Western Ridge Sends Record-Breaking 90s Surging Into the Northern Plains
UNITED STATES — A rare and intense March heatwave is sweeping across the western and central United States, setting hundreds of temperature records and pushing conditions more typical of late spring or even summer into the heart of March.
New data from March 20, 2026, shows a stunning number of locations either breaking, tying, or approaching daily, monthly, and even all-time temperature records. The most extreme heat is concentrated across Colorado, Wyoming, Nebraska, Kansas, Texas, Oklahoma, and New Mexico, with the warmth expanding northward into the Northern Plains.
Widespread Record-Breaking Heat Across the West and Plains
The map highlights an overwhelming cluster of magenta and red markers, indicating locations that have either tied or broken monthly and daily high temperature records.
- Colorado, Wyoming, and Utah are among the hardest-hit regions, with dense clusters of record-breaking temperatures.
- Kansas, Nebraska, and Oklahoma are also seeing widespread daily record highs fall.
- Across Texas and New Mexico, numerous stations are pushing into extreme heat levels for March.
Some of these records are not just daily milestones — they are challenging long-standing March benchmarks, with a few locations even nearing all-time record highs for this time of year.
Heat Expands Toward the Midwest and Mississippi Valley
The warmth is not confined to the West. A large zone stretching into the Missouri Valley, Iowa, Arkansas, and parts of Illinois and Missouri is seeing temperatures within a few degrees of records.
- Yellow markers across these regions indicate areas within 3°F of record highs, meaning additional records could fall with even slight warming.
- Cities across the central U.S. are experiencing temperatures far above seasonal averages, signaling an unusually strong early-season heat event.
South Dakota and Northern Plains Enter the Heat Zone
Perhaps most striking is how far north the heat is pushing.
Forecast trends show temperatures surging into the 90s as far north as South Dakota, an extremely rare occurrence for March.
This northward expansion highlights the strength of the ridge dominating the central U.S., allowing summer-like heat to penetrate deep into the Northern Plains.
Why This Heat Event Is So Unusual
This event stands out for several reasons:
- Timing: March typically brings transitional weather, not widespread summer-level heat.
- Geographic Spread: The heat spans from the Southwest through the Plains and into the Midwest.
- Record Intensity: Many locations are not just breaking daily records but also monthly and potentially all-time records.
- Consistency: Several records were set over consecutive days, indicating a persistent and powerful pattern.
Meteorologists are describing this as a “historic roaster” across the central United States — a phrase that reflects both the intensity and the widespread nature of the heat.
What Comes Next
The heat is expected to peak and expand further north and east, with additional records likely over the next 24 to 48 hours.
- More 90-degree readings are expected across parts of the Plains.
- Areas currently near records could tip into record-breaking territory.
- The unusual warmth may also set the stage for future severe weather patterns, as strong temperature contrasts develop.
A March to Remember Across the Central U.S.
From the Rockies to the Plains, this event is rewriting the record books.
With hundreds of locations already impacted and more records likely, this March heatwave is shaping up to be one of the most significant early-season warm events in recent history.
Residents across affected states are urged to stay aware of rapidly changing conditions as this historic heat surge continues to unfold.
