38 F. average high on March 9.
57 F. high on March 9, 2015.
Trace of rain fell yesterday (drizzle).
March 10, 2012: The record high of 66 degrees at the Twin Cities is the first of 8 record highs in a 10-day span.
March 10, 1948: Bitterly cold conditions, especially for March, occur in Minnesota. A low of -44 is reported at Itasca.
Springy Next 7 Days - One More Slushy Smack?
I apologize. I may have inadvertently angered the weather gods with my "winter is over" comment the other day. It's the kind of black and white statement that invites atmospheric retribution.
We just enjoyed/endured the 8th warmest meteorological winter on record in the Twin Cities. Open water in December. 10 subzero nights (typical for Kansas City). One real "storm" on Groundhog Day. 70F on Tuesday was the 3rd earliest on record at MSP.
The same El Nino signal pounding California and flooding some parishes in Louisiana with a tropical storm's worth of rain keeps us mild the next 7 days. 60F is possible Friday and Saturday before light showers arrive on Sunday. Models spin up a more impressive storm next Wednesday; probably warm enough aloft for heavy rain (and strong winds) but I can't rule out a little slush or a light mix late next week as temperatures cool off.
NOAA's GFS model hints at a few stronger/colder slaps of Canadian air within 1-2 weeks but the ECMWF model keeps the coldest air to our north.
Spring break is coming early this year - but hold off on gardening a little while longer.
3 PM Friday. Here is why I'm concerned, widespread 60s, even a chance of 70F over western and southwestern Minnesota Friday afternoon. NAM guidance hints at 63 F in the metro - just mild enough to break out into a spring-fever-sweat. Source: AerisWeather.

Warmest Winter on Record for the USA. Following the warmest year on record (2015), which broke the previous record for warmth (2014), when there was no El Nino to blame - or thank. It must be another coincidence. Here's an excerpt from NOAA NCDC: "The strong El Niño that was present in the Equatorial Pacific interacted with other climate patterns to influence U.S. weather conditions during winter and February. The December-February average temperature for the contiguous U.S. was 36.8°F, 4.6°F above the 20th century average, surpassing the previous record of 36.5°F set in 1999/2000. The exceptionally warm December boosted the contiguous U.S. winter temperature. The February temperature for the contiguous U.S. was 39.5°F, 5.7°F above the 20th century average, ranking as the seventh warmest on record and warmest since 2000..."
It's Official: This Was America's Warmest Winter on Record. More perspective from Eric Holthaus at Slate; here's a clip: "...NOAA blames the recent warm weather on a record-strength El Niño “and other climate patterns,” most notably, global warming. As a whole, this winter in the lower 48 was about 4.6 degrees Fahrenheit warmer than the 20th century average: a sharp contrast to the previous back-to-back frigid polar vortex winters, especially in the Northeast. But that doesn’t mean there was a lack of wintry weather: New York City, for example, had one of its warmest and snowiest winters on record, an odd combination to say the least..."
Extreme Weather Disasters Since 2010. A short window of data, but an interesting overview of state and national trends in recent years, courtesy of Environment America: "Every year, weather-related disasters injure or kill hundreds of Americans and cause billions of dollars in damage. Many of the risks posed by extreme weather will likely increase in a warming world. Scientists have already noted increases in extreme precipitation and heat waves as global warming raises temperatures and exacerbates weather extremes. The stories shared on the map show how global warming is affecting our lives as individuals. The negative impacts of global warming are felt differently by different people, depending their age, health and circumstances. For some, record heat can be life-threatening, while large snow storms can leave others trapped inside..."

Highest Ever Annual Rise in Carbon Dioxide Levels Reached. New Scientist has an update; here's the intro: "It is not just temperature records that are falling. The average carbon dioxide level recorded at Mauna Loa, Hawaii, during February 2016 was 404.02 parts per million – 3.76 ppm higher than the average for February 2015, according to preliminary figures. That is the biggest ever increase over a 12-month period. The previous 12-month record at Mauna Loa was 3.70 ppm, from September 1997 to September 1998..."
Darkening Greenland Ice Sheet Melts Faster. Here's an excerpt from Climate Home: "Greenland is getting darker. Climatology’s great white hope, the biggest block of ice in the northern hemisphere, is losing its reflectivity. According to new research, the island’s dusty snows are absorbing ever more solar radiation, which is likely to accelerate the rate at which the icecap melts. The Greenland icecap covers 1.7 million square kilometres and contains enough ice to raise sea levels by seven metres. Right now, the rate of melting is on the increase, and meltwater flowing off the icecap could be raising sea levels by 0.6mm a year..."

Climate Scientists Step Up Search for "Holy Grail" of Million-Year-Old Ice. The Guardian has a story focused on getting an even longer ice core record; here's a clip: "Somewhere deep below the ice in Antarctica lies a time capsule. It’s the holy grail of climate science and promises to reveal the past and future of Earth’s atmosphere. And right now, scientists are meeting in Hobart to work out a plan to dig it up. The time capsule is ice that froze 1.5m years ago, capturing tiny bubbles of air, bringing a sample of the ancient atmosphere through time to the present day. There are already dozens of ice cores from Antarctica and Greenland. They are tubes of ice, sometimes several kilometres long, drilled from the ice sheet, which reveal a timeline of what the atmosphere was like over hundreds of millennia..."

Engineers typically design systems to withstand reasonable worst-case conditions based on historical records; for example, an engineer builds a bridge strong enough to withstand floods based on historical rainfall and flooding. But what happens when the worst case is no longer bad enough?
"If we don't adapt the systems, they will break," said Duane Verner, an urban planner who works with Clifford.
