Winter storm possibly biggest to hit Iowa in three years

News, Weather

December 21st, 2012 by Ric Hanson

The first major winter storm of the season left a wide range of snowfall totals across Iowa. Harry Hillaker is the State Climatologist. He says the heaviest snow, 13.8 inches, fell at the National Weather Service office in Johnston. Marshalltown reported 13 inches of snow, while the Des Moines Airport recorded 12.4 inches. Areas of northeast Iowa are also reporting high snowfall totals with 10 inches in Waterloo and up to 11 inches in Dubuque. Meanwhile, many areas of far northwest and southeast Iowa received just 1 to 3 inches snow. Hillaker says this blizzard may be the biggest winter storm to hit Iowa since December 8-9, 2009 — although that event was more widespread.

“A larger area of heavy snow occurred with that December 2009 storm,” Hillaker said. “We had a statewide average of 10.3 inches of snowfall. This current storm will probably end up being around 6 to 6.5 inches for a statewide average.” This storm, like the one in 2009, included high winds that helped knocked out power to tens-of-thousands of Iowans. The National Weather Service reported winds of 40 to 50 miles per hour across much of the state Thursday, with a 60 mile per hour wind gust recorded in Ottumwa. This blizzard could also be compared to a massive winter storm that blanketed Iowa in early January 1996 when nearly 14 inches of snow fell in Des Moines. Hillaker notes there was already a lot of snow on the ground when that storm hit.

“And it was a much colder storm. Temperatures were in the teens when the snow started, so it was a very dry, fluffy snow that drifted very badly compared with this current event as temperatures were near freezing and the snow was a bit stickier,” Hillaker said. The snow that’s on the ground across Iowa won’t be melting anytime soon as high temperatures are expected in the teens to low 30s over the next several days. The next chance for snow arrives early next week, including Christmas Day.

Carroll: 6 inches
Clarinda: 2.5 inches
Creston: 5.5 inches
Denison: 8 inches

First blizzard of the season blasts Iowa with snow, wind

News, Weather

December 20th, 2012 by Ric Hanson

Heavy snow’s already on the ground from the first major snowstorm of the season. Several counties in central Iowa report more than a foot of snow while a cluster of counties in northeast Iowa have nearly 11 inches. In Atlantic, we received 7-inches of snow outside the KJAN studios from 3-pm Wednesday through 7-a.m. today (Thursday).

National Weather Service meteorologist Kevin Skow says the blizzard is beginning to ease.  “At this point, the storm is starting to pull slowly away from the state but we still have widespread snow across most of Iowa,” Skow says. “That should slowly taper off during the mid-to-late morning hours from west to east.” If you think you heard thunder last night — you did, and there was lightning, too. That’s “thundersnow,” according to Skow.

“Thundersnow is not terribly uncommon with these very strong systems,” he says. “And you have very strong winds. It’s a very strong system and that’s what led to that thundersnow.” While the snow is starting to lessen in western and central Iowa, Skow says another threat will remain through this afternoon.

“The big story today will be the winds,” he says. “We’re expecting strong winds, 30-40 miles per hour or even 50 to 60 mph wind gusts which will blow that snow around and create hazardous travel conditions.” Snowfall totals show three deep areas in the state — near Council Bluffs, around Des Moines, and between Dubuque and Waterloo. The deepest report is 13-point-1 inches, just north of Des Moines.

(updated 4:54-a.m.) Midwest hit by its first major snowstorm of season

December 20th, 2012 by Ric Hanson

DES MOINES, Iowa (AP) – Forecasters are warning that the Midwest’s first major snowstorm of the season could cause blizzard conditions this morning from Kansas to Wisconsin. And there are predictions that some areas in a swatch stretching from northwest Missouri, into Milwaukee, Chicago and Michigan could get as much as much as a foot of snow. The conditions could threaten operations at Chicago’s O’Hare airport. A Blizzard Warning remains in effect until Noon today, for much of Iowa.

Heavy overnight snow has forced some school districts in Nebraska and Iowa to close. Drivers in Nebraska have been told to avoid treacherous roads. In western Kansas, some tractor trailers jackknifed or tipped. A clerk at a travel center in the town of Tribune says a stranded UPS driver had to spend the night with a family.

One meteorologist says the snow is a nuisance, but the moisture is welcomed by farmers in the drought-parched region. Some areas are more than 12 inches below normal precipitation for the year.

Some businesses in the KJAN listening area are either closed or will be starting late. Please see the “Cancellations” section under the “Community Hub” tab on KJAN. com for updates throughout the day. The snow will be tapering-off early this morning, with reports in western Iowa thus far ranging from 3-to 6-inches. Drifts of up to nearly a foot were common in the open areas, as well.

Midwest hit by its first major snowstorm of season

News, Weather

December 20th, 2012 by Ric Hanson

DES MOINES, Iowa (AP) — The first major snowstorm to hit the Midwest this season is sweeping across the region, shuttering schools and creating dangerous driving conditions. Forecasters are warning that heavy snowfall coupled with strong winds will create blizzard conditions Thursday from Kansas to Wisconsin. The weather is also threatening to cause delays at O’Hare International Airport in Chicago, the nation’s second-busiest airport, ahead of the busy holiday weekend.

Nebraska’s largest school district canceled classes because of heavy overnight snow, as did many districts across Iowa, where drivers are being told to stay off the roads because of whiteout conditions. The heaviest snow is expected across a swath extending from northwest Missouri into Milwaukee, Chicago and Michigan. As much as a foot of snow could fall in some areas.

Blizzard Warning remains in effect until Noon today (Thursday)
