- Blog Post by: Paul Douglas
- October 20, 2012 - 3:31 PM
52 F. high in the Twin Cities yesterday.
57 F. average high for October 19.
49 F. high on October 19, 2011.
Getting Better. Friday's rain, coupled with partial clearing and light winds overnight created thick fog and low stratus, which is gradually eroding statewide. Expect intervals of cool sun this afternoon - highs poking into the 50s. Visible loop courtesy of WeatherTap.
50 Shades Of Gray. No wait, that's something different. WeatherNation TV meteorologist Bryan Karrick snapped this photo of a ragged, showery sky Friday afternoon.
.21" rain fell on the Twin Cities Friday, the biggest 24-hour rainfall since August 15.
4.15" rainfall deficit since September 1.
70+ F. highs expected on Sunday, 60-degree highs thru the first half of next week.
30s a week from Sunday? A much colder front is 5-6 days away.
Warmer, drier bias lingering into February for Minnesota? Latest winter outlook from NOAA below.
“This is one of the most challenging outlooks we’ve produced in recent years because El Niño decided not to show up as expected,” said Mike Halpert, deputy director of NOAA’s Climate Prediction Center. - from a NOAA update below.
21 of 28 counties served by the La Crosse, Wisconsin National Weather Service have been declared Natural Disaster Areas due to the growing drought. Details below.
"...Their paper, “The Republicans Should Pray for Rain: Weather, Turnout, and Voting in U.S. Presidential Elections” confirmed the conventional wisdom that weather does affect voter turnout, bad weather benefits Republicans and most interestingly, two presidential elections in the last 60 years may have had different results had the weather been different..." - excerpt from a story focused on the impact of weather on presidential elections over the years, details and links below.

Deer-Hunting Opener Outlook? Don't bet the farm on this one (or any long-range weather forecast, for that matter), but I'll dial up the GFS details for the first weekend of November below.
Indian Summer Alert. A distractingly nice weekend is on tap, more typical of early or mid September than late October. Expect upper 50s to near 60 today; temperatures may top 70 tomorrow, with highs at or above 60 thru the first half of next week, according to the ensemble of models above. Graph: Iowa State.
One Wild Weather Ride. After peaking near 70 Sunday, again Tuesday of next week. Next Wednesday looks like the best chance of significant rain, even a few heavier T-storms in the area. After a mild Friday the floodgates open, cold air sweeping into Minnesota next weekend. The ECMWF (European) model has highs in the 30s a week from Sunday!
Today's Weather Map. The WRF model shows showery rains from Detroit and Flint to Buffalo, a soaking rain for upstate Maine, lighter, showery rains for Seattle and Portland by 4 pm today. Much of the USA stays dry today.
Elusive El Nino Challenges NOAA's 2012 U.S. Winter Outlook. The on-again, off-again El Nino warming of Pacific Ocean water is looking shaky, the odds now close to 50/50, basically a coin-flip. So NOAA has tweaked the winter outlook from December thru February - here's an excerpt of a longer explanation: "The western half of the continental U.S. and central and northern Alaska could be in for a warmer-than-average winter, while most of Florida might be colder-than-normal December through February, according to NOAA’s annual Winter Outlook announced today from the agency’s new Center for Weather and Climate Prediction in College Park, Md. Forecasters with NOAA’s Climate Prediction Center say a wavering El Niño, expected to have developed by now, makes this year’s winter outlook less certain than previous years.
“This is one of the most challenging outlooks we’ve produced in recent years because El Niño decided not to show up as expected,” said Mike Halpert, deputy director of NOAA’s Climate Prediction Center. “In fact, it stalled out last month, leaving neutral conditions in place in the tropical Pacific.” When El Niño is present, warmer ocean water in the equatorial Pacific shifts the patterns of tropical rainfall that in turn influence the strength and position of the jetstream and storms over the Pacific Ocean and United States. This climate pattern gives seasonal forecasters confidence in how the U.S. winter will unfold. An El Niño watch remains in effect because there’s still a window for it to emerge..."
Meteorological Mirage or Reality: Heading Into a Stormier Pattern? When the NAO (North Atlantic Oscillation), a measure of the capacity for the atmosphere to become stuck in a blocking pattern, goes negative, odds of significant storms tend to rise, especially east of the Mississippi. A strongly negative signal in late October and early November may signal a better chance of Gulf moisture reaching Minnesota. I hope it's not wishful thinking.
Drought Brings Pleas To Cut Back Water Use. Bill McAuliffe at The Star Tribune takes a closer look at Minnesota's growing drought and the potential need for water restrictions; here's an excerpt: "With rivers and rainfall approaching record low levels, state officials said Thursday they want homeowners to eliminate "nonessential" water use, such as lawn watering and car washing, and have told farmers to abide strictly by irrigation permits. In parts of the state, some residential wells have run dry or had flow reduced by commercial and residential neighbors, said Dave Leuthe, deputy director of Ecological and Water Resources at the Department of Natural Resources. Continued lack of rain could prompt the DNR, under terms of a drought action plan, to require specific water conservation targets for users, particularly cities. In recent weeks it has suspended 50 permits for surface water use by businesses, golf courses and parks departments across the state, though many have backup water sources..."
Infographic map details above: "The map below is based on data released each Thursday at 8:30 a.m. Eastern Time. The drought monitor combines numeric measures of drought and experts' best judgment into a weekly map. It is produced by the NDMC, the U.S. Department of Agriculture and the National Oceanic and Atmospheric Administration and incorporates review from 300 climatologists, extension agents and others across the nation. Each week the previous map is revised based on rain, snow and other events, observers' reports of how drought is affecting crops, wildlife and other indicators."
Minnehaha "Falls". Lakes, rivers and streams are at historically low levels across much of Minnesota; here's a photo from Jeff Wheeler at The Star Tribune that sums up the state of our weather: "Step into Minnehaha Creek this fall and your feet won’t even get wet.And the thundering waterfall? Just a drip.With little rain, flow dwindled in late summer, and the dam that releases water from Lake Minnetonka into the creek was closed Aug. 20 to maintain the lake’s level.(Dam closings have happened before.) Contrast the gravel-bed look of today with June 2011, left,when heavy rain caused streams to swell near flood levels. The dangerous,muddy conditions didn’t keep tourists from venturing near the falls."
Drought Killing Young Trees Over Southeastern Minnesota. Here's an excerpt of a post from the La Crosse, Wisconsin office of the National Weather Service: "...Drought impacts include:
- River flows are well below normal. The flows were less than 20 percent of normal along the Bloody Run, Cedar, Little Cedar, Mississippi, Root, Turkey, Upper Iowa, Volga, and Zumbro South Fork.
- Record low ground levels have been established within the past month near El Dorado, IA in Fayette County (17.33 feet below ground on September 23, 2012 - the previous record was 17.11 feet on February 6, 2009) and Fort McCoy Military Reservation in Monroe County (9.15 feet below ground on October 12, 2012 - the previous record was 8.62 feet on October 7, 1987).
- Some young trees have died. Young and recently planted trees died in Winona County in southeast Minnesota and Monroe, Adams, and Juneau counties in Wisconsin.
- 21 of our 28 counties have been declared Natural Disaster Areas. This includes: Allamakee, Chickasaw, Clayton, Fayette, Floyd, Howard, Mitchell, and Winneshiek counties in northeast Iowa; Fillmore, Houston, and Mower counties in southeast Minnesota; and Adams, Clark, Crawford, Grant, Jackson, Juneau, La Crosse, Monroe, Richland, and Vernon counties in western Wisconsin."
72 Hour Rainfall Forecast. WSI's RPM model (through Monday evening) shows the heaviest rains and mountain snows over the far west, a couple feet of snow possible for the Cascade Range of the Pacific Northwest. A little light rain spreads across the Upper Midwest by Monday, harbingers of larger storms to come by the middle of next week.
QPF. NOAA HPC's 5-day rainfall outlook shows significant rain from the Great Lakes into northern New England, some 2-4" rainfall amounts from northern California into the Pacific Northwest.
Low Water Levels on Lake Superior. Here's a post from the Marquette office of the National Weather Service, via FB: "You may have heard that the Great Lakes water levels are below normal. According to the U.S. Army Corps of Engineers, as of October 17, 2012, Lake Superior was at 600.69 feet, which is 1.41 feet below the long-term average of 602.1 ft and 0.1 feet below the all time record low for October of 600.7 ft set back in 1925. The other Great Lakes are also below normal and very near the all time record lows for October. Mean levels are calculated by averaging the best available guage data at report generation and are subject to change."
Will The Weather Determine The Next President? Here's an excerpt of a fascinating post at ThorntonWeather.com: "Looking back at presidential elections from 1948 to 2008, the study takes into account the weather in 3,000 U.S. counties. They in turn looked at key areas of the nation and how weather, good and bad, affected voter turnout. In the end, the study determined that precipitation is the key weather condition to affect voter turnout.
In part, the study says:
We find that rain significantly reduces voter participation at the polls by a rate just under one percent per inch. Snowfall also decreases turnout, but only in rural counties. Moreover, we show that the estimated number of voters lost due to precipitation significantly benefits the Republican Party’s vote share and GOP incumbents particularly.
According to the study, if there was an inch of rain more than normal in a given area, nearly 1 percent fewer voters turned out and the Republican presidential candidate received an extra 2.5 percent of the vote. For every inch of snow above normal, overall voter turnout was depressed by 0.5 percent and the Republican candidate’s vote share increased by 0.6 percent."
A Chilly Hunting Opener? The extended GFS model shows highs in the 30s and 40s the first weekend of November, with a few tenths of an inch of precipitation. 850 mb temperatures range from -2 to -7 C, cold enough for wet snow, or possibly a rain-snow mix. Although I don't see a heavy snow accumulation for the metro (yet) I could envision some slush on the ground for tracking up north. Stay tuned...
Could A Hurricane Ever Strike Southern California? With warming oceans the idea isn't as far-fetched as it might sound at first blush. Tropical storms have struck San Diego and L.A. before, a long time ago, so the odds aren't zero, but California residents probably shouldn't lose much sleep over this. Here's an excerpt of a NASA JPL story: "There's an old adage (with several variations) that California has four seasons: earthquake, fire, flood and drought. While Californians happily cede the title of Hurricane Capital of America to U.S. East and Gulf coasters, every once in a while, Mother Nature sends a reminder to Southern Californians that they are not completely immune to the whims of tropical cyclones. Typically, this takes the form of rainfall from the remnants of a tropical cyclone in the eastern Pacific, as happened recently when the remnants of Hurricane John brought rain and thunderstorms to parts of Southern California. But could a hurricane ever make landfall in Southern California? The answer, as it turns out, is yes, and no. While there has never been a documented case of a hurricane making landfall in California, the Golden State has had its share of run-ins and close calls with tropical cyclones. In fact, California has been affected by at least a few tropical cyclones in every decade since 1900. Over that timeframe, three of those storms brought gale-force winds to California: an unnamed California tropical storm in 1939, Kathleen in 1976 and Nora in 1997. But the primary threat from California tropical cyclones isn't winds or storm surge. It's rainfall -- sometimes torrential -- which has led to flooding, damage and, occasionally, casualties..."

The storm eventually turned westward away from land, but still brought rainfall to parts of Southern California and high surf." Image credit: NASA/NOAA/NRL
Study Shows How Prayer, Meditation Affect Brain Activity. I'm always on the lookout for stories, photos and commentary that make me do a double-take. Here's one that fits the bill from Huffington Post: "How does prayer and meditation affect brain activity? Dr. Andrew Newberg, MD is the Director of Research at the Myrna Brind Center for Integrative Medicine at Thomson Jefferson University Hospital and Medical College and he has studied the neuroscientific effect of religious and spiritual experiences for decades. In a video that recently aired on "Through the Wormhole" narrated by Morgan Freeman on the TV channel Science, Dr. Newberg explains that to study the effect of meditation and prayer on the brain, he injects his subjects with a harmless radioactive dye while they are deep in prayer / meditation. The dye migrates to the parts of the brain where the blood flow is the strongest, i.e,. to the most active part of the brain..."
"The Lost Wheels" on TPT Almanac. If you missed the live show Friday evening on KTCA, Channel 2, you can watch the replay here. I babbled on about the drought, but the highlight of the show (for dear old dad) was seeing my oldest son play lead guitar for an up and coming Twin Cities band. Am I a little biased? Yep, but I know good music when I hear it. You can hear some of the tracks on their new CD, "Chipper" at their home page. Hey, I'm hoping Walt supports me in my old age!

Land of 9,000+ Lakes
It's all "weather-hype" until the water stops coming out of your faucet. Based on DNR warnings I sense we're close to water restrictions, and no wonder. With a 4-5" shortfall since September, many towns have missed the equivalent of 2 month's worth of rain.
Lake, river & stream levels are approaching historic levels. After a wet spring rainfall went over a cliff. Record summer heat increased evaporation, accelerating water loss and drying out Minnesota's topsoil.
Recent rains have helped a little over far western Minnesota, but NOAA's revised winter outlook shows a dry bias lingering into February.
So as excited as I am about a welcome rerun of Indian Summer, I'd be thrilled to be tracking a sloppy, southern "storm". Skies clear today, 60s likely much of next week; 70 F not out of the question. Some light rain is expected Monday, Wednesday, again next weekend - before it cools off in time for a chilly Halloween. At this rate drought may be the Big Story into 2013.
Today's weather blog includes a Hunting Opener Outlook (guess), and why Republicans may be praying for a wet, stormy Election Day.
Yes, there seems to be a real correlation between weather and voter turnout.

Eyes On The Earth. NASA has impressive on-line tools to be able visualize Earth's morphing climate, including real-time global tracking of carbon dioxide and carbon monoxide (showing huge plumes of pollutants sweeping across China into the Pacific). The map above shows global temperatures from Friday. By downloading a JAVA applet you can manipulate all these data sets in 3-D. Very cool.
Why The Chill On Climate Change? Here's an excerpt of a thoughtful (on the money) Op-Ed at The Washington Post: "...Why does it matter that nobody is talking about climate change? Because if you accept that climate scientists are right about the warming of the atmosphere — as Obama does, and Romney basically seems to as well — then you understand that some big decisions will have to be made. You also understand that while there are some measures the United States could take unilaterally, carbon dioxide can never be controlled without the cooperation of other big emitters such as China, India and Brazil. You understand that this is an issue with complicated implications for global prosperity and security. A presidential campaign offers an opportunity to educate and engage the American people in the decisions that climate change will force us to make. Unfortunately, Obama and Romney have chosen to see this more as an opportunity to pretend that the light at the end of the tunnel is not an approaching train."
Climate Change: Journalism's Never-Ending Fight For Facts. Here's an excerpt of a story at The Guardian's Environment Blog: "The debate about climate change is dogged – possibly even defined – by its interminable, intractable tug of war over the "facts". A hand grenade is lobbed into no-man's land triggering a volley of return fire. But, when the dust settles, can anyone truly claim to have advanced their position? Of course, the art of "manufacturing doubt" has long been in the playbook of those hoping or needing to divert attention away from evidence. We saw it a generation ago with smoking, just as we see it today with climate change. But knowing how this blatant tactic is deployed doesn't make it any easier to nullify or deter. Compounding the problem is the speed at which "facts" can now spread unchallenged across the internet. Rebutting or contextualising inaccuracies takes expertise and, above all, time and energy..."

The Sad History Of Climate Policy, According to David Brooks. Here's a clip from an important Ezra Klein Op-Ed at The Washington Post's Wonkblog: "...So, to summarize: Addressing climate change by pricing carbon — an idea Brooks supported then and supports now — was a bipartisan project in 2003. It became a partisan project because Al Gore thought it was important enough to make a documentary about. Republicans began opposing efforts to price carbon, in part because they hate Al Gore. That left funding renewables research as the only avenue for those worried about climate change. Funding renewables research means funding some projects that won’t work out, and some that might make Al Gore rich. This led to bad publicity that tarnished the whole program. The passivity of Brooks’s conclusion is astonishing. This isn’t a story of overreach, misjudgements, and disappointment. It’s a story of Republicans putting raw partisanship and a dislike for Al Gore in front of the planet’s best interests. It’s a story, though Brooks doesn’t mention this, of conservatives building an alternative reality in which the science is unsettled, and no one really knows whether the planet is warming and, even if it is, whether humans have anything to do with it. It’s a story of Democrats being forced into a second and third-best policies that Republicans then use to press their political advantage..."

A Rogue Climate Experiment Outrages Scientists. An attempt at geo-engineering climate (without any permission?) Scientists gone rogue? Here's a clip from a New York Times article: "A California businessman chartered a fishing boat in July, loaded it with 100 tons of iron dust and cruised through Pacific waters off western Canada, spewing his cargo into the sea in an ecological experiment that has outraged scientists and government officials...Marine scientists and other experts have assailed the experiment as unscientific, irresponsible and probably in violation of those agreements, which are intended to prevent tampering with ocean ecosystems under the guise of trying to fight the effects of climate change..."
Interior Department Creates Climate Change Committee. Here's the intro to a story at Human Events: "The Obama administration is creating an advisory committee on climate change to advise the federal government on future operations. The Interior Department announced the new bureaucracy in a recent federal registry notice along with a call for nominations by Nov. 19 to seat the 25-member board. The notice specifically states membership will be comprised of state and local government employees, non-governmental organizations, Native American tribes, academia, individual landowners and business interests...."
Extreme Global Warming Caused Devastating Die-Off. The Christian Science Monitor reports; here's a snippet: "Feverishly hot ocean surface waters potentially reaching more than 104 degrees Fahrenheit (40 degrees Celsius) may have helped cause the greatest mass extinction in Earth's history, researchers say. "We may have found the hottest time the world has ever had," researcher Paul Wignall, a geologist at the University of Leeds in England, told LiveScience. The mass extinction at the end of the Permian Era about 250 million years ago was the greatest die-off in Earth's history. The cataclysm killed as much as 95 percent of the planet's species. One key factor behind this disaster was probably catastrophic volcanic activity in what is now Siberia that spewed out as much as 2.7 million square miles (7 million square kilometers) of lava, an area nearly as large as Australia. These eruptions might have released gases that damaged Earth's protective ozone layer..."
