Unprecedented Heat Wave Grips Western US

A remarkable heat wave impacted the central and western United States in mid-March, leading to a surge in record-breaking temperatures. Weather stations across the West reported more than 8,200 daily records and over 2,000 monthly records broken during this period.

Record-Breaking Numbers

Preliminary data indicates that seven states experienced their highest March temperatures on record. Specifically, 3,331 weather stations across the West set new daily record high temperatures on March 18th and 22nd. An additional 1,598 stations recorded their highest March temperatures ever.

Historical Context

Analysis of data from 247 U.S. towns reveals that the number of record highs this March surpasses any other month since 1950. The previous record was set in June 1952, with 771 record highs. In 429 locations, weather records extend back over 100 years.

State-Specific Records

The heat was particularly intense in several states. Arizona’s Yuma reached 109 degrees, exceeding the previous state record of 104 by five degrees. New Mexico saw temperatures reach 100 degrees in Tucumcari and Cavern City, surpassing the previous March high of 94.

Impact Across Multiple States

Iowa experienced unprecedented heat, with 20 stations recording temperatures above 91 degrees, culminating in a high of 97 degrees in Little Sioux. California reached a new state record for March with 112 degrees at Buttercup & Squaw Lake. Nevada, Utah, and Wyoming also set new March temperature records.

Early Spring Bloom

The unusually warm temperatures have triggered an early bloom for leaves in the central Plains and parts of the West. However, the spring bloom remains delayed in other regions of the country.
