Stubborn atmospheric blocking pattern brings days of thunderstorms for High Plains, Rockies

·2 min read

A week of strong thunderstorms along the High Plains will continue into Saturday as the severe weather threat stretches from Montana into West Texas.

It's the latest chapter in a stubborn weather pattern that looks to keep active weather around that area of the U.S. for several days.

A Rex block pattern this weekend over the Great Lakes will result in "trapping" an overall area of disturbed weather over the Rockies, according to the FOX Forecast Center. This will continue to bring daily chances for showers and storms into the weekend, mainly during the afternoon and evening hours.


On Friday, severe weather alerts were issued for millions from Wyoming to the Lone Star State. Large amounts of hail covered the ground in communities in New Mexico, Texas and Colorado.

In Encino, New Mexico, hail stones of 3.5" in diameter broke windshields, while in Hereford, Texas, spotters reported several inches of accumulated hail as a thunderstorm passed through.

In Colorado Springs, two people were struck by lightning on a golf course, according to the Colorado Springs Fire Department. Medics were called to the Valley Hi Golf Course around 3:40 p.m. for a report of two injured in a lightning strike. They arrived to find one person who had suffered an apparent direct hit and a second person who may have been indirectly struck. Both had stable vital signs when taken to a local hospital.

Thunderstorms triggered the issuance of Tornado Warnings in eastern Colorado on Saturday afternoon.

At least one twister was spotted in rural areas around Converse County.

There were no initial reports of injuries or damaged from the tornado.


The forecast for Sunday still has lingering thunderstorms with an area of low risk for severe thunderstorms drifting a little farther south into western Kansas and the Oklahoma Panhandle. Again, large hail and damaging winds are the likeliest threats, but an isolated tornado can't be ruled out.

Daily thunderstorms remain in the forecast for the Rockies as well. With the Omega block locked in, this pattern looks to stick around for the foreseeable future.
