2013: 6th warmest year on record, globally, to date.Source: NOAA.

341 July was the 341st consecutive month with global temperatures warmer than the 20th century average.

 

 

Late August Heat Wave

 

Earth continues to run a low-grade fever: July the 341st month in a row of global temperatures warmer than the 20th century average. NOAA says it was the 6th warmest July, worldwide, since 1880.

The warming has been anything but uniform. I'm seeing more random heat "spikes", surges of intense heat and humidity that come on suddenly.

One such hot front is brewing for next week, and if ECMWF (European) model guidance can be believed, next week could wind up being the hottest of the year for much of Minnesota. Yes, very unusual for late August, considering the sun is now as high in the sky as it was in late April.

Then again "unusual" is the new normal.

Today will be a breath of fresh (Canadian) air, dew points dropping into the 40s behind a welcome cool front. Comfortable weather lingers Friday, but a sticky wave of overheated air returns Saturday, sparking a few T-storms. By Sunday we may be sizzling in the mid-90s. Low to mid 90s are predicted for much of next week. Our on-again, off-again summer will be in high gear; bad news for schools with no A/C.

For 4 weeks we were stuck under a cool, northwest flow. Next week a heat bubble stalls out directly over Minnesota.

 

Wednesday Severe Storms. The leading edge of cooler air set off a squall line over the south metro yesterday afternoon, reports of 1"+ hail from Henderson to Lakeville to Hastings. Over 2.5" of rain fell at Chippewa Falls, Wisconsin, with a few reports of funnel clouds east of Eau Claire. A complete damage report from NOAA here.

 

Next Week: Mostly 90s? I'm looking for continuity from model run to run, but the ECMWF is consistent, showing highs in the low to mid 90s much of next week. After a 36 hour break in the dew point department (comfortable 40s today!) expect a dew point near 70 F. from Saturday afternoon into most of next week. Something to look forward to.

Summer's Coming Late This Year. Yes, we had a spell of real summer in early July, then a surge of September that lasted the better part of  4 weeks. Now it's time for Summer, Part 2, starting Saturday afternoon, extending into next week, with 90s possibly spilling over into Labor Day. The map above shows predicted highs next Tuesday, courtesy of WeatherBELL. 100F heat isn't out of the question over the Dakotas, even far southwest Minnesota.

 

Dog Days of Late August. Here is the latest 6-10 day temperature outlook from NOAA's Climate Prediction Center, showing a sizzling bulls-eye over the Northern Plains and Upper Midwest; temperatures as much as 15-20 F. warmer than average for late August. Map: Ham Weather.

 

In Search Of Normal. Here is a Ham Weather map showing normal highs for August 22. Temperatures over the Upper Midwest may run as much as 15-20 F. warmer than average from this weekend into much of next week.

 

Flashback To February 1985. That's the last time the planet had a cooler than average month. In today's Climate Matters I take a look at #341, put July (and the year to date) into context: "Just how long has it been since the world had a below average month? You have to go back to February 1985! WeatherNationTV Chief Meteorologist Paul Douglas goes over the data that made July the 341st consecutive month above the 20th century average."

 

Atlantic Basin Primed For An Above-Normal Hurricane Season. Yes, it's very quiet out there - and we have yet to see our first hurricane of the season in the Atlantic. Based on a variety of factors (less Saharan dust, warmer water temperatures, low wind shear) I suspect September will be a lot busier than August has been. More details from NOAA's Climate.gov: "Andrea, Barry, Chantal, Dorian, Erin*... who’s next? Probably plenty more, according to NOAA’s updated Atlantic hurricane season outlook. With five named storms already in the books this summer, the 2013 hurricane season is shaping up to be above normal, and there is a possibility that it could be very active during the peak of the season from mid-August through October. An additional 9-15 named storms are likely, of which 6-9 are predicted to become hurricanes, with 3-5 reaching major hurricane status. Among the climate factors behind the heightened activity? Heat. These maps show the tropical cyclone heat potential of the tropical Atlantic Ocean ramping up between May 24 (bottom) and August 4 (top). This “hurricane heat potential” depends not just on the surface temperature, but on the depth of the warm water..."

 

National Hurricane Center Gives Storm Surge Modeling A Major Boost. Here's a clip from an interesting story at The Washington Post's Capital Weather Gang: "The National Hurricane Center (NHC) is running an improved version of its old, reliable storm surge model on faster computers to help emergency managers update hurricane evacuation plans. When a storm threatens any place in the U.S. NHC forecasters will use the improved, faster-running model to predict its surge. Hurricane forecasters know those who might be in a hurricane’s path tend to focus on the storm’s wind speed, which define its one-to-five category.  “The categories put a focus on wind; people are absorbed by wind,” says Jamie Rhome, the NHC’s storm surge lead, but “water is what kills the vast majority of people. Evacuations are done for surge...”

More Active Pattern Eastern Pacific. The map above shows predicted model tracks for a developing tropical storm off the coast of Mexico. It should pass west of Cabo San Lucas, and there's a small, outside chance that some of the moisture from this system could push into far southern California.

July: 341st Month/Row Of Warmer Than Average Global Temperatures. Meteorologist Andrew Freedman has the story at Climate Central; here's a clip: "The year-to-date has been the sixth warmest on record globally, and July was also the sixth warmest such month since global surface temperature records first began in 1880, according to new data released on Tuesday by the National Oceanic and Atmospheric Administration (NOAA). The figures show that July 2013 was the 37th straight July, and the 341st straight month, with warmer-than-average global temperatures — a more than 28-year timespan that reflects the significant warming observed worldwide since the 1970s. That means that no one under the age of 28 has ever experienced a month in which global average surface temperatures were cooler than average (based on the 20th century average)..."

 

Can We Trust Google With The Stratosphere? A planetwide constellation of nearly stationary, high-altitude balloons sharing the Internet (and Google!) with the entire world? It sounds like science fiction, but now I'm not so sure, after reading this article at The Atlantic; here's an excerpt: "The challenge is simple. Simple enough for a child to explain. In fact it's a child's voice, over a rolling piano and elegant animation that introduced Google's bold new step into the future: Project Loon. "For each person that can get online, there are two that can't... What if there was a way to light up the entire world? And make all of the world's information accessible to all of the world's people?"  It's a challenge that Google aims to answer -- with a soaring, international balloon armada, beaming Internet to the parts of the world that don't have it....The proposed delivery system has thus far escaped similar scrutiny, which is too bad, because the very mechanics of Project Loon highlight serious legal, diplomatic, and government tensions, which Google is either ignoring, unaware of, or operating in spite of. And yet, that said, it's not Google's job to enforce regulatory oversight; breaking ground means new rules have to be invented, too..." (Photo credit: Google).

 

Tesla's A Threat To The Auto Industry, But Detroit's Reacting All Wrong. LinkedIn has the story - here's a clip: "A recent flurry of articles, such as this one on Forbes, reported Steve Girsky’s disclosure of GM’s new secret team, tasked with studying EV maker Tesla and its CEO Elon Musk. There is probably no one better than Girsky, GM’s current vice chairman and a former leading automotive analyst on Wall Street, to study and understand the threat and opportunity that Tesla represents for the car industry. Tesla’s $15B+ market cap demonstrates that the stock market is betting on Tesla’s potential to take a significant share of the broader car market, not just luxury cars. If those analysts are right, GM shouldn’t be the only company worried about Tesla’s future plans. The entire car industry should probably study Tesla, to understand if and how it plans to take such market share from all current incumbents. Assuming they will all learn the same underlying secret, what car will they make after they finished their collective hypothetical study?..."

Climate Stories...

Editor: Awaiting A Climate Change Tipping Point. Here's the intro to an Op-Ed at The Concord Monitor: "One of these days, the tipping point will be reached. No, not the tipping point that leads to a continued warming of the globe. That one, unfortunately, is probably behind us. The even more elusive tipping point is the action, event or increased collective concern that finally prompts Americans to make combatting climate change a national goal akin to winning a world war. Hurricane Katrina didn’t do it, and neither have Hurricanes Sandy and Irene. So the notion that a slim book and a barnstorming state senator from Iowa will spur the nation to action seems far-fetched. But Sen. Rob Hogg’s book, America’s Climate Century, and his talks across the state this week should move the needle in the right direction. Hogg, who met with Monitor editors yesterday, makes the convincing case that for the next half-century or more “every aspect of our lives will be affected by human-caused global warming and its resulting climate changes, and by the actions necessary to stop climate change before it devastates the world...”

 

How Extreme Will Future Heatwaves Be? Choose Your Own Adventure. The Guardian has the story - here's an excerpt: "...Coumou & Robinson looked at the frequency of rare and extreme (3-sigma, meaning 3 standard deviations hotter than the average) and very rare and extreme (5-sigma) temperature events. 3-sigma represents a 1-in-370 event, and 5-sigma is a 1-in-1.7 million event. As shown in the video below from NASA, summer temperatures have already begun to shift significantly towards more frequent hot extremes over the past 50 years. What used to be a rare 3-sigma event has already become more commonplace..."

Climate Change Has Arrived In California (Op-Ed). Here's a snippet of a story at Yahoo News: "The report concludes that climate change is occurring throughout California, from the Pacific Coast to the Central Valley to the Sierra Nevada Mountains.

Among other findings, the report concluded that:

  • Warming temperatures have accelerated since the 1970s, with nighttime temperatures increasing much faster than daytime;
  • Changes in precipitation patterns have had the effect of decreasing water supplies, even when overall rainfall remains the same;
  • Carbon dioxide levels in coastal waters are harming species and having effects throughout the marine food chain;
  • Over the past century, water levels have risen along the California coast by an average of 7 inches (18 centimeters), and levels have risen by 8 inches (20 centimeters) at the Golden Gate; and
  • Annual acreage burned by wildfires since 2000 is double the rate of the previous 50 years, from less than 300,000 acres to almost 600,000..."
