Strong thunderstorms threaten Logan County with hail, high winds Sunday evening

Hail as large as one-half inch and winds near 50 mph threatened northwestern Logan County through 8:15 p.m. Monday, putting anyone on the road or trying to finish outdoor plans on a short clock. The same alert covered northeastern Weld County, while a separate warning for north central Morgan County remained in effect until 7:30 p.m.

The National Weather Service’s Denver/Boulder office said a few severe storms were possible across northeast Colorado through the afternoon and evening. Isolated to scattered storms were expected to develop along the I-25 corridor by mid-afternoon and move east across the plains through early evening, a track that put western and central portions of the region in the path of the first storms to strengthen.

Forecasters said very large hail was expected from any severe storms, and some cells could also produce high winds and a tornado threat. The weather service urged residents to stay weather aware and move cars to a garage if time permits, a reminder that hail can turn a routine evening commute into a costly scramble within minutes.

The Logan County and Morgan County weather pages also showed active severe-weather monitoring for both counties, underscoring that the threat was being watched closely as storms developed. That matters in a part of Colorado where damaging weather has a long track record, especially in early June.

National Weather Service event summaries include the June 8-9, 2020 Northeast Colorado severe thunderstorm event, which produced wind gusts from 60 to 80 mph and a few localized gusts up to 100 mph. Damaging winds extended into Logan County during that storm, and another event summary lists a June 18, 2018 hail event in Morgan County. Colorado Climate Center severe-weather climatology, which compiles tornado, thunderstorm wind and hail reports from 1955 through 2025, shows how often northeast Colorado has faced this kind of severe setup.

For Logan County residents, the most immediate step was simple: get vehicles protected now, watch the sky closely through the evening, and expect the worst storms to be the ones that can turn hail and wind into damage fast.
