Expect stormy weather, including hail and strong winds, in metro Denver and across the Eastern Plains on Sunday afternoon as an upper-level disturbance centered over Arizona pushes into the state.
“We could see a few severe storms, probably starting after 1 p.m., with the highest threat extending from Denver to the Wyoming border,” said Scott Entrekin, a meteorologist with the National Weather Service in Boulder.
The storms could become severe enough to produce large hail, up to 2 inches in diameter, with damaging winds and possibly a tornado, he said.
Low-level moisture increased sharply overnight and temperatures are expected to approach 80 degrees.
“We have enough ingredients so that whatever storms do develop will go severe,” Entrekin said.
Southeastern Colorado, extending up into Cheyenne and Kit Carson counties, is expected to see the most intense activity. But northeast Colorado, from the metro area to the Kansas and Nebraska borders, is forecast to see thunderstorms that will send those enjoying the holiday outdoors scrambling for cover.
Storms are expected to last through midnight, after which things will calm down. Memorial Day also looks like an unsettled day for weather, with severe storms possible north of Denver to the Wyoming border, Entrekin said.
