Hello NSCO community! I wanted to go ahead and catch us up on our monthly climate summaries. March across Nebraska featured a highly dynamic pattern, with sharp temperature swings, persistent dryness, and significant fire weather concerns dominating much of the month. Early in the month, conditions were cool and dreary, particularly across eastern Nebraska, including Omaha and O’Neill, where low clouds, drizzle, and even freezing drizzle kept temperatures in the 40s and lower 50s. Western locations such as Scottsbluff and North Platte saw slightly warmer conditions at times, but overall moisture remained limited. As the month progressed, a strong warming trend occurred, with locations like Kearney and Valentine frequently climbing into the 70s and 80s. By mid-to-late March, an extraordinary and historic heat event pushed temperatures into the mid to upper 90s across parts of central and southern Nebraska, including areas near Grand Island, marking some of the warmest March temperatures on record. This heat, combined with extremely low humidity, often dropping into the teens or even single digits, led to widespread critical fire weather conditions and multiple Red Flag Warnings. Major wildfires, including the Morrill and Cottonwood fires, burned large areas of land and had statewide impacts. Precipitation throughout the month remained below normal overall, with only brief periods of light rain or drizzle, allowing drought conditions to persist and worsen.
From a synoptic and upper-air perspective, March was largely controlled by various ridging and troughing patterns that drove these temperature extremes. Early in the month, weak shortwave troughs and low-level warm-air advection supported widespread cloud cover, drizzle, and fog across much of the state. As the pattern evolved, a strong upper-level ridge became the dominant feature, particularly during mid-March, when 500 mb heights rose significantly, promoting subsidence, clear skies, and intense surface warming. At 850 mb, temperatures surged well above normal, often exceeding 20°C, which enhanced boundary-layer mixing and allowed the extreme warmth to reach the surface. This ridge also suppressed precipitation and dried out the atmosphere. Later in the month, the pattern became more active again, with shortwave troughs embedded in southwesterly flow at 500 mb and increased jet support at 300 mb helping to reintroduce precipitation chances. Surface features followed suit, with warm air advection ahead of ridges and strong cold fronts driving abrupt temperature drops of 20–30°F in some cases.
At the surface, several notable features defined the month. Multiple cold frontal passages swept through Nebraska, often producing strong northerly wind shifts with gusts reaching 35 to 50 mph, especially across central and eastern portions of the state. These fronts were critical in transitioning from extreme warmth to cooler conditions, but often lacked sufficient moisture to produce widespread precipitation. Ahead of these fronts, dry, warm, and windy conditions created ideal fire-weather conditions, particularly across western Nebraska and the Sandhills. In addition, persistent surface high pressure and downslope flow at times contributed to warming and drying, while occasional surface lows and shortwave disturbances helped generate isolated showers or thunderstorms, mainly later in the month. Gravity wave influences were less dominant but may have contributed to localized wind enhancements during strong frontal passages.
Precipitation across Nebraska during March was generally limited and highly variable. Early in the month, widespread drizzle and light rain produced minor accumulations, especially across eastern Nebraska, with totals generally under 0.25 inches. Mid-month conditions turned much drier, with little to no measurable precipitation during the peak heat and fire weather period. Late in the month, a more active pattern allowed for modest precipitation totals, generally ranging from 0.25 to 0.75 inches across central and eastern Nebraska, with localized higher amounts possible. Northern Nebraska, including areas near Valentine, saw brief periods of rain mixing with light snow overnight.
Temperature and Precipitation Extremes (March 2026):
Maximum High Temperature: Upper 90s°F, south-central Nebraska (near Grand Island/Hastings region)
Minimum High Temperature: Low to mid 40s°F, eastern Nebraska, early month
Minimum Low Temperature: Upper 20s°F, northern Nebraska, late month
Maximum Low Temperature: Mid to upper 40s°F, statewide during warm periods
Maximum Precipitation: ~0.75 inches, central/eastern Nebraska late month
To wrap things up, March 2026 was a classic example of early-spring variability across the Central Plains, but with an added extreme twist: record-breaking heat and widespread wildfire impacts. The month transitioned from cool, moist, and cloudy conditions to exceptionally warm, dry, and dangerous fire weather, before finally shifting toward a slightly cooler and more active pattern by the end of the month. Looking ahead into April, the pattern suggests continued variability, with periodic chances for precipitation offering some hope for drought relief. However, fire weather concerns may remain elevated, especially during warm, dry, and windy periods. As fuels remain dry across much of Nebraska, it will be important to monitor fire risk closely, while also watching for the increasing potential for severe weather as the spring season progresses.
