What the Radar Record Shows for Wyoming Storms
By StormAuditor Editorial Team · Published 2026-08-27 · Updated 2026-08-27
Based on public NOAA and National Weather Service records, published under StormAuditor's methodology and data-source standards. Radar-derived hail sizes are estimates unless attributed to a ground report.
Wyoming logged 8,525 storm events across 23 counties in 12 months, with gusts to 109 mph and radar-estimated hail to 7.03 inches. Here is what warnings, reports, and radar show.
A wind gust reached 109 mph in Wyoming on March 12, 2026. That same day logged 710 separate wind events, the busiest storm day of the past year. Ground stations alone did not tell that story. Wyoming's observers are spread across huge distances. The public record leans on three streams of evidence: National Weather Service warnings, spotter and public reports, and radar. Here is what those streams show for the state, day by day and county by county.
Wyoming's storm file, in three kinds of evidence
The trailing 12 months produced 8,525 recorded storm events across 23 Wyoming counties. Wind accounts for 8,177 of them. Hail adds 892. Flood events number 56, and tornadoes 29.
Each event type carries a different kind of evidence. Warnings show where forecasters saw a threat forming. Reports confirm what a person actually observed on the ground. Radar covers the space in between, and in Wyoming that space is enormous. A storm can cross an entire county here without passing a single weather station.
Wind dominates the record
Five gust days stand out in the data. The top reading hit 109 mph on March 12, 2026. December 9, 2025 brought 102 mph. Two separate days, April 22, 2026 and December 17, 2025, each reached 100 mph. February 17, 2026 peaked at 99 mph. For context, the NWS severe threshold for wind is a 58 mph gust. Every one of these days cleared it by a wide margin.
Winter carries much of that load. December 17, 2025 alone generated 669 wind events, and December 19 added 297 more. January 16, 2026 logged 279. High-wind season in Wyoming runs through the cold months, not just thunderstorm season. Contractors who only check summer dates can miss the state's biggest wind days entirely.
Hail shows up on radar first
Radar-estimated hail (MRMS MESH) reached 7.03 inches over Wyoming on June 22, 2026. That figure is an algorithm's read on a storm core, not a measured stone on the ground. It still flags a day worth researching. Other radar-estimated peaks include 3.89 inches on June 8 and 3.43 inches on June 2. Radar estimates for August 12 and July 3 came in at 3.34 and 3.18 inches, all in 2026. Each of those radar-estimated sizes sits above the 2.00-inch mark the NWS uses for significant severe hail.
One day mixed everything at once. June 20, 2026 produced 270 events spanning hail, tornado, and wind, the most varied hazard day in the 12-month file.
Where the events cluster
Carbon County leads the state with 1,750 events in 12 months, and 1,613 of those were flagged at NWS severe criteria. Laramie County follows at 1,224 events, with 1,067 at severe levels. Albany County recorded 1,114. Behind them sit Platte (590), Campbell (440), Converse (372), Fremont (362), and Goshen (289). The heaviest activity tracks the state's southeastern quarter and the I-80 corridor, where Carbon, Albany, and Laramie counties absorb storm after storm.
In the recent detail window, Uinta County posted 15 screening-level events with wind to 74 mph, and Fremont County reached 75 mph. Laramie County's detail file includes hail to a radar-estimated 1.50 inches.
How StormAuditor estimates it
StormAuditor's SAWE-2 wind engine and SAHE-2 hail engine blend NWS warnings, ground reports, and MRMS radar into one address-level estimate of the record. Every output is an estimate of what that record shows, never a measurement at your roofline. The full approach is documented at /methodology/wind and /methodology/hail.
Using this record as a property owner
Start with the date, not the damage. If a hailstorm or windstorm may have crossed your property, pin down the candidate date first. Then pull what the record shows for that day at your address. An address lookup turns a statewide storm day into a location-specific estimate.
Adjusters and contractors face a specific Wyoming problem: a gust that the record supports at one ranch may have no nearby station reading at all. Radar-derived estimates and warning polygons become the working evidence. Treat them as a starting point for date-of-loss research, then compare against inspection findings.
Keep the thresholds straight. StormAuditor screens events at 45 mph wind and 0.75-inch hail — screening thresholds, nothing more. NWS severe criteria sit higher, at 58 mph gusts and 1.00-inch hail. A screening-level event is a reason to look closer, not a conclusion.

Limitations
These figures estimate the public weather record; they do not establish what happened at any single address. MESH hail sizes come from radar algorithms and can run larger or smaller than stones on the ground. That is especially true at extreme values like the June 22 reading. Wind maxima reflect the strongest supported value in the state, which may sit far from your property. Warning polygons show forecast concern, not confirmed impact. Read the full discussion at /limitations before relying on any single number.
Frequently asked questions
What was Wyoming's strongest recent wind gust?
The 12-month record shows a top gust of 109 mph on March 12, 2026. That day also produced 710 wind events statewide, the year's busiest storm day.
Did Carbon County, Wyoming have storms this past year?
Yes. Carbon County recorded 1,750 events in the trailing 12 months, the most of any Wyoming county. Of those, 1,613 were flagged at NWS severe criteria.
Was there hail in Laramie County, Wyoming?
The recent detail window shows radar-estimated hail to 1.50 inches in Laramie County, along with wind to 56 mph. Over 12 months, the county logged 1,224 events, second in the state.
What hail size counts as severe in Wyoming?
NWS criteria set severe hail at 1.00 inch or larger, and significant severe at 2.00 inches. StormAuditor screens smaller events, down to 0.75 inch, as screening-level activity worth a closer look.
How do I research a specific Wyoming storm date?
