NORTH LIBERTY, Iowa - People across the Midwest reported seeing a bright fireball streak across the sky Thursday evening ... and it was caught on camera in North Liberty.

The fireball, a possible meteor, was spotted at about 5:40 p.m. Thursday. Reports indicated that it was seen across many Midwestern states, including Iowa, Illinois, Minnesota, Missouri, Wisconsin, Nebraska and South Dakota.

Contamination from commercial products such as nonstick cookware and stain repellents could reduce the reproduction of tree swallows nesting in Minnesota and Wisconsin, according to a new U.S. Geological Survey study.
USGS scientists and partners found that tree swallow eggs exposed to elevated levels of these products, known as perfluoroalkyl substances (PFASs), were associated with a decreased chance of hatching. PFASs are common environmental contaminants that have been used in products such as water and stain repellents, nonstick cookware, surfactants such as detergents and wetting agents, and polymers (plastics). The report was recently published in Archives of Environmental Contamination and Toxicology.
"Even though PFASs seem to be declining in the environment, hot spots still remain," said Christine Custer, USGS Upper Midwest Environmental Sciences (UMESC) scientist and lead author of the study. "These high concentrations are localized, however, which fortunately reduces the potential for harm to swallow populations throughout Minnesota and Wisconsin."
Between 2007 and 2011, scientists compared hatching rates among tree swallow nests located at eight different study locations with different PFAS-contamination levels and sources in Minnesota and Wisconsin, including Lake Johanna and Pigs Eye Lake in the Twin Cities metropolitan area—two areas known for PFAS contamination. They tested an egg sample from each studied nest for PFAS concentrations and compared those results to how well the rest of the eggs hatched.
The USGS-led study suggested that tree swallow hatching rates declined at high PFAS concentrations (as high as 150-200 nanograms per gram of wet weight), which are lower than the concentrations that have affected other bird species in laboratory studies. This difference may be due to behavioral effects or other factors not accounted for in the laboratory studies. It could also mean that tree swallows are especially sensitive to these toxins.
PFASs can enter the environment through contaminated groundwater and surface water runoff from plants that manufacture or use PFAS products, from household waste water that passes through treatment plans, and from airborne chemicals settling on the ground. The Mississippi River downstream of St. Paul, Minn., may have been contaminated by a landfill used to dispose of PFAS-filled waste products.
Because of global exposure to humans and wildlife, selected PFASs were phased out of production starting in 2000.
This study was led by the USGS in collaboration with the U.S. Environmental Protection Agency, the State University of New York at Albany and the U.S. Fish and Wildlife Service.

Drought - State of Minnesota, [Golden Valley region]

Description
The metro area started the summer with heavy rains wiping out much of the drought. Now because of the lack of rain since, "severe" drought has made its way back to parts of the north metro. "The worst of the drought stretches from the St. Cloud area through the northern Twin Cities metro right down the Mississippi River through Winona," said climatologist Pete Boulay. Boulay reported the worsening drought outlook Thursday. "They're about 4 inches short at the airport. If you live in Anoka, Washington, Ramsey Counties you're about five inches short of normal," he said. "If you live down in Winona, they're missing eight inches of rain." It's turned lush lawns into crunchy fields. The more brown underneath Frank Rothanburg's shoes, the less green in his pockets. "There's no work with all the grass being dead. There ain't nothing to do," said Rothanburg. He estimates his Anoka company, Superb Lawn Care, has lost $40,000 over the summer. "We've got places we haven't mowed in three weeks now because they're just so burnt up," he said. And it's not just rain that's missing. "We've only seen maybe between 10 or 12 tornados for the year. And that's well below normal," said Boulay. And according to Rothanburg, even watering every other day isn't helping. He is now hoping "Mother Nature" steps in. "Nothing's helping. We need rain bad," said Rothanburg.

Drought worsens in Midwest, South; affects crops

DES MOINES, Iowa (AP) — The combination of heat and scarce amounts of rain intensified the drought in several agriculturally significant states, contributing to declining crop conditions in parts of the Midwest and South.
However, the U.S. Department of Agriculture said in a separate report Thursday the expected record corn harvest and third-largest soybean crop are on track, since areas that aren’t seeing as severe a drought will produce enough to make up for the driest regions.
Crops in states such as Kentucky and Tennessee look better than they did a month ago, the USDA said, while Iowa and Missouri are suffering from the heat.
‘‘The fringes of the corn belt are producing enough to offset Iowa’s loss,’’ said Chad Hart, agriculture economist at Iowa State University.
This week’s national drought monitor, which tracked conditions from Sept. 3 to Tuesday, shows nearly 50.7 percent of the contiguous United States is now in moderate drought or worse, up from just over 50 percent the week before.
The report said in Iowa, the nation’s largest corn producer, severe drought spread to nearly 42 percent of the state — up from 32 percent a week ago. All but two of the state’s counties, both in east-central Iowa, are experiencing some level of drought or abnormally dry conditions.

More than half of USA in a drought

Drought is at its largest percentage since April.

Drought covers more than half of the country and is at its largest percentage since early April, according to this week's U.S. Drought Monitor, a weekly federal website.
As of Tuesday, 50.7% of the contiguous USA is in a drought.
Hot, dry weather over the past week led to worsening drought in the central USA: In the Midwest, where temperatures have been as much as 10 degrees above normal over the past week, drought expanded in parts of Missouri, Iowa, Illinois, Indiana, Minnesota and Wisconsin, according to the monitor.
For example, since July 1, La Crosse, Wis., has received only 2.4 inches of rain, the driest July 1-Sept. 10 period on record for that location.
