Gazette Premium Content Plains threatened by same spring snowstorm that hits Rockies

DENVER (AP) — A powerful spring storm dropped more than a foot of sloppy, wet snow in parts of Colorado and Wyoming on Mother's Day, and forecasters warned that instability ahead of the cold front created conditions ripe for tornadoes and severe thunderstorms in the Plains states.

The National Weather Service issued a winter storm warning for most of northern Colorado and parts of southern Wyoming for all of Sunday and for Monday morning. Strong thunderstorms and tornadoes developed in Nebraska and were threatening to push south on Sunday. The storm also created high winds across the West.

Kyle Fredin, a meteorologist for the weather service in Boulder, said the weather pattern is typical for this time of year, and "it's going to be kind of the same thing pretty much through the end of June."

Several tornadoes were reported in southern Nebraska, blowing down outbuildings, damaging homes and knocking out power. Large hail and strong winds seen in the state were expected to head south into Kansas, and a tornado watch was issued for parts of Oklahoma.

The storm was expected to weaken as it heads northeast from the Plains, possibly bringing rain as it moves into the Great Lakes, the weather service said.

In Colorado, Department of Transportation officials said plunging temperatures and heavy, wet snow created icy road conditions, and multiple accidents were reported on several highways.

Southwest of Denver, a seven-car pileup Sunday evening injured a sheriff's deputy on U.S. 285 near the community of Doubleheader, The Denver Post reported (http://bit.ly/1uSsRFP ). Three others were hurt, but their injuries didn't appear to be life-threatening.

Weather was likely a factor in the crash, but its cause was still being investigated, sheriff's spokeswoman Jacki Kelley told the newspaper.

"The roads are just really bad out there," she said.

Snow amounts could vary greatly as temperatures continue to drop later Sunday. But up to 15 inches could fall at higher elevations and 4 to 9 inches could fall at lower elevations, including Denver and other cities along Colorado's Front Range.

"May snow certainly isn't unheard of here in Colorado, even down in the Denver metro area," said David Barjenbruch, another weather service meteorologist in Boulder. "If we see the total accumulations that we are anticipating from this storm, we are certainly going to see a top 10 May snow event for the Denver metro area."

Barjenbruch said a foot of snow had already fallen in the foothills of Larimer County northwest of Denver by Sunday morning, and workers along much of the Front Range can expect a "slushy, sloppy morning commute" Monday.

The weather service also warned that snow could be heavy and wet enough to snap tree limbs and power lines, causing power failures. Winds gusting up to 30 mph could reduce visibility, and slushy roads could be treacherous to drive.

Julie Smith, a spokeswoman for Denver International Airport, said crews have treated runways in anticipation of dropping temperatures Sunday night.

"At this point we are seeing some delays with our airlines while they are getting their deicing operations up and running, and we do expect the airlines to be fully deicing in the morning," she said.

Meanwhile, Denver officials plan to deploy up to 70 snowplows overnight to prepare for Monday's commute.

In southern Wyoming, the storm forced transportation officials to close a 150-mile stretch of Interstate 80 from Cheyenne to Rawlins on Sunday.

The weather service said mountainous areas in south-central Wyoming got up to 2 feet of snow, and the metro areas of Cheyenne and Laramie averaged 6 to 10 inches. Rob Cox, a weather service meteorologist in Cheyenne, said he expects more accumulation overnight, likely an additional 2 to 4 inches in some locations.

"There will be a lot of water after all this is said and done," he said, adding that there could be some localized flooding.

In the West, high winds at the bottom of the storm sent dust blowing across Arizona and New Mexico, and the Los Angeles area had been under "red flag" fire warnings, with authorities saying blazes could quickly spread out of control under low humidity, gusty winds and dry conditions.

The storm is the result of a low-pressure system moving east colliding with a cold air mass from the north. Spring-like weather was expected to return to the Rockies by Tuesday.
