Intense thunderstorm drops 2 inches of rain in northeast Denver
Moisture streaming northeastward across Colorado has triggered another round of heavy thunderstorms.
FRISCO — With rain gages picking up anywhere from 1 to 2.5 inches of rain over northeastern Denver, the National Weather service has issued a flash flood warning for Denver International Airport and surrounding areas.
Flooding is expected in northern Aurora, northeastern Commerce City, Brighton, Denver International Airport’s terminal concourses and Barr Lake.
The flash flood watch is in effect through 9:30 p.m. The NWS is urging people to move to higher ground: “Act quickly to protect your life.” Small creeks and streams will overflow, with danger spots along highways, especially at underpasses.

Peak intensity of rainfalls during storms is increasing.
Rising temps are drastically changing rainfall patterns
FRISCO — After carefully analyzing 30 years of rainfall data in Australia, scientists said they tracked a clear pattern of intensifying peak rainfall during storms that will lead to increased flash flood risks in Australia’s urban catchments.
Civil engineers from the University of New South Wales Water Research Centre analyzed close to 40,000 storms across Australia, finding that warming temperatures are dramatically disrupting rainfall patterns, even within storm events. Continue reading

Hikers, motorists warned about overflowing streams and rivers
Subtropical moisture streaming into Colorado is triggering more flood concerns.
Flooding is possible in southwest Colorado, parts of the high country, as well as many Front Range streams.
FRISCO — With more subtropical moisture streaming into Colorado from the Southwest, parts of the state are under flood watches and flood warnings at the start of the weekend, including:
- South Boulder Creek near Eldorado Springs,
- Cache La Poudre River near Greeley affecting Weld County.
- South Platte River at Henderson affecting Adams County.
- South Platte River near Kersey affecting Weld County.
- South Platte River near Weldona affecting Morgan County.
- South Platte River near Balzac affecting Logan, Morgan and
In the high country, the Eagle River is expected to come close to overflowing this weekend, with a flood advisory for the weekend. Other rivers running high include the Roaring Fork between Aspen and Glenwood Springs and the Colorado River from the Eagle/Grand County line to the Utah border. Continue reading

Months of record-high temperatures are amplifying the impacts of California’s dry spell.
Sizzling temps kill snowpack, bake soil
FRISCO — The California drought is all the worse because of warmer temperatures, U.S. Geological Survey scientists said this week in a new study that reinforces previous findings.
The research focused on a one-year span, from Oct. 2013 to Sept. 2014, showing that, if the air temperatures had been cooler — similar to the 1916-2012 average — California’s critical winter snowpack would have been bigger, leading to more runoff and lower soil moisture deficits in the summer.

Extreme storms can happen outside expected times
FRISCO — A new study led by Colorado-based scientists seems to reinforce the old saying that, when it comes to the state’s weather, there’s no such thing as normal.
The research aimed to track seasonal and geographical patterns of extreme weather events, especially the monster storms that create headaches for emergency responders and resources managers. But pinpointing those trends is not easy the weather experts found. Continue reading

FRISCO — There’s been lots of speculation and some early research on a possible link between soaring temperatures in the Arctic and extreme weather in North America and Europe, but the jury is still out, according to scientists with the National Oceanic and Atmospheric Administration.
NOAA’s James Overland was part of an international team that took a close look at possible connections and concluded that more research is needed.
“We are in the pre-consensus stage of a theory that there are links between the rapid warming of the Arctic and some severe weather events since 2007,” said Overland, lead author of the new study, “The melting Arctic and Mid-latitude weather patterns: Are they connected?” Continue reading

Population growth in warm zones is a big part of the equation
FRISCO — Extreme heat kills more people than any other type of extreme weather, and that mortality could increase significantly in coming decades as the Earth warms under a blanket of heat-trapping greenhouse gases.
Americans’ exposure to extreme heat could increase four- to six-fold by 2050, a new study concludes, explaining that it’s not just the heat — the country’s population is growing especially fast in the hottest regions of the country. Continue reading
