December Puddles (50s by Monday; historic rain/snow storm brewing for west coast of USA)

Posted by: Paul Douglas Updated: November 28, 2012 - 11:20 PM

 

Amazing Grace

The Lord is my shepherd; I shall not want.

The measure of a person isn't what they have, but what they give, right?

My mom passed away yesterday. I wish you could have known her. Grace was a force of nature. She grew up dirt-poor, in a tent, during The Depression. She raised 3 kids, went on to become a prolific antiques dealer. She taught us the most important lesson: family comes first. "Do the right thing ... never give up" she'd say with a stern smile. I was in awe of her. I still am. Todd Nelson will be filling in while I'm with family.

The weather map is mercifully quiet. Roughly 3 weeks from the Winter Solstice it seems odd to be tracking rain; drizzle Saturday, a few heavier showers and T-showers Monday.

Expect highs from 45-50 F. over the weekend, then well into the 50s on Monday, before cooling down by midweek.

We thaw out late next week, but colder air building over Canada arrives by the second week of December. Any snow by mid-month will come in dribs & drabs; still no sign of The Big One. I'll keep searching.

My loss hasn't hit me yet. A word to the wise: take no one for granted. Do the right thing. Never give up. And give mom extra hugs.

Do it today.

 

Staggering Precipitation Amounts. WSI's high-resolution (12 kilometer) RPM model prints out about 4-5" for San Francisco and Portland, Oregon, but as much as 16-20" of precipitation for northern California. That's 1-2 hurricane's worth of moisture, which may translate into some 150-200" snowfall amounts for the Cascade and Sierra Range. If this forecast verifies some areas of the west will experience historic river flooding and an extreme avalanche risk.

 

December On Hold. The 6-10 day temperature trends show temperatures well above average across most of the USA, thanks to a persistent wind flow from the Pacific - Canadian air temporarily bottled up in Canada. Map above: NOAA CPC and Ham Weather.

 

Zonal Flow. Typical for late September or mid-October, a (persistent - vigorous) west to east wind flow from the Pacific is a bit more unusual heading into the first week of December. The NOAA animation above shows 500 mb winds (18,000 feet) thru Saturday.

 

Above Average. The first full week of December may bring highs consistently above freezing, in fact most of the days will probably feature highs in the 40s. 50+ F. highs are possible Monday, again late next week, based on latest ECMWF guidance.

 

NAEFS Guidance. Experimental long-range guidance for December 5 - 11 shows a continuing block, keeping Alaska bitter, with mild Pacific winds pumping 40s, 50s and 60s into the Lower 48 states.

 

Monday: Hints of Early April? A strong warm front may spark showers, even a stray T-shower Monday. South of the warm frontal boundary highs may reach the 60s in Iowa and Nebraska, 50s into southern Minnesota. Slightly cooler weather returns Tuesday, but temperatures recover into the 40s and 50s again by late next week as Pacific air continues to overwhelm the Lower 48. Map above: WSI.

 

Temperature Readjustment? The long-range 16-day GFS shows significantly colder air returning by December 12-13, a storm tracking just south and east of Minnesota capable of triggering some accumulating snow. My confidence level is still low, but it sounds right - with a sun angle as low as it is in mid-January it can't stay in the 40s and 50s much for an extended period, at least not in December.

 

Flu Outbreaks Predicted With Weather Forecasting Techniques. Outbreaks of flu tend to follow specific weather patterns - which is interesting. Predict the weather (accurately) and maybe you can predict when you'll come down with the crud? Lovely. Details from UCAR: "...In previous work, Shaman and colleagues had found that wintertime U.S. flu epidemics tended to occur following very dry weather. Using a prediction model that incorporates this finding, Shaman and co-author Alicia Karspeck, an NCAR scientist, used Web-based estimates of flu-related sickness from the winters of 2003–04 to 2008–09 in New York City to retrospectively generate weekly flu forecasts. They found that the technique could predict the peak timing of the outbreak more than seven weeks in advance of the actual peak. “Analogous to weather prediction, this system can potentially be used to estimate the probability of regional outbreaks of the flu several weeks in advance,” Karspeck says. “One exciting element of this work is that we've applied quantitative forecasting techniques developed within the geosciences community to the challenge of real-time infectious disease prediction. This has been a tremendously fruitful cross-disciplinary collaboration.”

Trees Are Shedding Leaves Later Than Usual. Here's a clip from EarthSky.org: "Scientists examined changes in the growing season over the Northern Hemisphere during 1982 to 2008 and found that end of the growing season has shifted to later in the year. Scientists regard changes in the growing season as an important indicator of the response of terrestrial ecosystems to climate change. The results of the research were published in the July 2011 issue of the journal Global Change Biology and were further reviewed by Climate Central on October 17, 2012. To measure the length of the growing season, scientists used NDVI (normalized difference vegetation index) data collected by satellites to estimate the “greenness” of vegetation growing across the Northern Hemisphere during 1982 to 2008. The NDVI calculates how much visible light is absorbed by vegetation. Healthy vegetation absorbs most visible light..."

 

Sandy Damage Rivals Katrina. Sandy wasn't as intense as Katrina, but it was 3 times larger, impacting an area 900 miles wide with tropical storm force winds or stronger. And it came ashore over a very heavily populated part of the USA. My hunch: Sandy will wind up costing over $100 billion. NBC News has more details: "Although Hurricane Katrina took more lives when it hit the Gulf Coast, the economic and housing damage brought by Hurricane Sandy was much larger with losses already topping $71 billion. NBC's Katy Tur reports."

 

Seas Rising Faster Than Projected, Low Areas Threatened. What, scientists were actually conservative with their estimates? But let's keep ignoring the elephant in the dining room (or in this case, on the coast). Reuters has the story; here's an excerpt: "Sea levels are rising 60 percent faster than U.N. projections, threatening low-lying areas from Miami to the Maldives, a study said on Wednesday. The report, issued during U.N. talks in Qatar on combating climate change, also said temperatures were creeping higher in line with U.N. scenarios, rejecting hopes the rate had been exaggerated. "Global warming has not slowed down, (nor is it) lagging behind the projections," said Stefan Rahmstorf, lead author at the Potsdam Institute for Climate Impact Research that compared U.N. projections to what has actually happened from the early 1990s to 2011..."

In Sandy's Wake, Lessons About Fire Safety More Relevant Than Ever. I know it's counterintuitive (during a flooding storm surge), but fire was a huge hazard with Sandy. More details from Benzinga: "...Many people still keep traditional candles as part of their hurricane or disaster preparedness kit. But these candles can create extra hazards if left unattended, even for a short time. In some cases, homeowners fall asleep with a candle burning and wake up to find the house burning around them. Battery operated candles are a much safer alternative and can also last much longer than regular candles..."

Turning To The Cloud In A Disaster. With Sandy I saw a number of people fleeing with photo albums and thumbdrives, even some lugging home computers filled with family memories. It was a reminder (to me) to back stuff up, the things that can't be replaced (like family photos and videos). The cloud is one good option, as Cisco explains: "Two weeks after Hurricane Sandy barreled up the East Coast, devastating parts of densely populated New York and New Jersey, the full costs of the megastorm are still being assessed. The "once-a-century" storm left more than 8 million homes and businesses without power, shutting down everything from oil refineries to transportation to the stock market. The disruption could shave a half percentage point off of GDP. Behind those statistics are millions of businesses, big and small, grappling with new questions disaster preparedness in an age of extreme weather. And, increasingly, they are concluding that the answers may lie in the cloud..."

 

"Ask Paul". Weather-related Q&A:

Last year it was a brown Christmas and that happens from time to time. When was the last time we had 2 brown Christmas in a row?

Mike

Chanhassen, MN

 

Mike - I asked my friend and contact at the Minnesota Climatology Working Group, Pete Boulay, about your question and here is his response: "The last time there was an inch of snow or less on the ground for two years in a row was Christmas 1976 and 1977. It also happened in 1957 and 1958 and 43-44, 30-31, 22-23,  and there was a three years in a row from 1904-06."

California City Building "Tsunami-Resistant" Port. Insurancejournal.com has the story; here's an excerpt: "...Port officials are hoping that tsunami is among the last of many that have forced major repairs in Crescent City, a tiny commercial fishing village on California’s rugged northern coast. Officials are spending $54 million to build the West Coast’s first harbor able to withstand the kind of tsunami expected to hit once every 50 years – the  same kind that hit in 2011, when the highest surge in the boat basin measured 8.1 feet (2.5 meters) and currents were estimated at 22 feet (6.7 meters) per second. Officials are building 244 new steel pilings that will be 30 inches (76 centimeters) in diameter and 70 feet (21 meters) long. Thirty feet (9 meters) or more will be sunk into bedrock. The dock nearest the entrance will be 16 feet (5 meters) long and 8 feet (2.4 meters) deep to dampen incoming waves. The pilings will extend 18 feet (5.5 meters) above the water so that surges 7 1/2 feet (2.3 meters) up and 7 1/2 feet down will not rip docks loose..."

California Confronts A Sea Change. The story from The Los Angeles Times; here's the introduction: "Governors Andrew Cuomo of New York and Chris Christie of New Jersey don't need to wait on gridlocked Washington to confront future risks from climate-change intensified storms. They can instead look at how California is already moving forward on common-sense adaptations, and do it themselves. With 3.5 million Californians living within three feet of sea level, and the best available science projecting a 3- to 5-foot rise in sea level for the state by 2100, doing nothing would be irresponsible. In Northern California, rising sea levels are projected to affect more than a quarter of a million people and threaten more than $60 billion in infrastructure in the San Francisco Bay/Delta region, putting power stations, water-treatment plants, roads, buildings and the San Francisco and Oakland airports (both built on filled wetlands) at risk. In Southern California, scientists point to the loss of 3,000 beachfront homes to major El Niño winter storms in the 1980s as suggestive of what climate change has in store..."

SGI Twitter Heat Map: Supercomputer Show Where The Angriest Tweeters Live. This is pretty cool, in a depressing sort of way. Silicon Graphics supercomputers can map, in real-time, where happy vs. angry tweets are sent from, worldwide. Here is a Huffington Post story showing how SGI leveraged this new technology tracking tweets during Superstorm Sandy: "...The Global Twitter Heartbeat tracks about 10 percent of the 500 million tweets posted daily -- that's approximately 50 million posts analyzed each day. Thus far, SGI has created heat maps illustrating people's feelings on Twitter about Hurricane Sandy and the 2012 election night. To see the project in action, watch the clip below, showing how U.S. tweets were affected as the so-called "Frankenstorm" barreled up the East Coast in late October. (Red patches represent negative sentiments. Blue patches are positive.)"

What Role Did Climate Change Play In Superstorm Sandy? PropertyCasualty360.com attempts to connect the weather and climate dots; here's an excerpt: "Superstorm Sandy, a “perfect storm” that was caused by an unusual combination of seasonal weather phenomena converging above the Northeast, has stirred some conversation in the media about whether the storm was caused, or made worse, by climate change. Scientists have long warned about the risk of a deadly hurricane over the Tri-State area, which would suggest Sandy could be an expected weather event. But recent studies, including a report co-authored by MIT climate scientist Kerry Emanuel in February 2012, note that climate change could combine with the  effects of storm surge to cause 100-year-flooding to occur every two decades in New York, suggesting that an event like Sandy may be more than just a long-expected storm..."

Climate Change Threat Looms Over Ski Industry. This may be relevant to Minnesota and Wisconsin resorts as well, as snowfall has become spotty and irregular in recent years - not the predictable snow we saw in the 60s, 70s and early 80s. The Boston Globe reports: "...Snow making will become even more important in the coming decades as New England’s natural snowfalls diminish, according to Scott’s study. Resorts are already spending millions of dollars to increase their capacity — Stowe Mountain Resort in northern Vermont spent $4.7 million this year alone — and by the 2020s, Vermont and New Hampshire resorts may have to increase their snow making output by as much as 50 percent. “Man-made snow is such an integral part of skiing on the East Coast,” said Greg Kwasnik, spokesman for Loon Mountain Resort in Lincoln, N.H. “People may not realize it, but man-made snow is what makes it all possible.” But snow making also depends on the weather cooperating — the temperature has to be in the low 20s or colder..."

Melting Permafrost A New Peril In Global Warming: U.N. The concern is methane - as permafrost melts methane is released, a greenhouse gas 20 times more powerful than carbon dioxide. This causes warming, which melts more permafrost, releasing more methane (etc etc). This is one of several "positive feedbacks" climate scientists are concerned about, as reported by Reuters: "Permafrost lands across Siberia and Alaska that contain vast stores of carbon are beginning to thaw, bringing with it the threat of a big increase in global warming by 2100, a U.N. report said on Tuesday. A thaw of the vast areas of permanently frozen ground in Russia, Canada, China and the United States also threatens local homes, roads, railways and oil pipelines, the U.N. Environment Programme (UNEP) said in the report which was released at the U.N. climate talks being held this week and next in Qatar. "Permafrost has begun to thaw," Kevin Schaefer, lead author at the University of Colorado told a news conference in Doha..." Photo: NASA.

 

Researchers Head To Coldest Place On Earth For Global Warming Insight. The Olympian has the story - here's a clip: "...For almost a month, the group will sleep in tents and toil for up to 15 hours a day in converted shipping containers. Temperatures hover around 5 degrees Fahrenheit and 90 mph winds create massive snowdrifts and whiteouts. The reason for enduring that misery would seem to be a contradiction. Their work will provide crucial insight into global warming. The NIU professors are researchers in a key part of a $10 million National Science Foundation project known as WISSARD, for Whillans Ice Stream Subglacial Access Research Drilling. It's a long-winded phrase for an effort aimed at studying ice sheet stability and subglacial life in West Antarctica. That's an important region for climate change. Scientific evidence indicates that relatively recent instability in the Antarctic ice sheet, which covers the land, is raising sea levels..."

U.N. Report Warns Of Widening Climate Gap. The Daily Herald has the story - here's the introduction: "A U.N. report on rising greenhouse gas emissions reminded world governments Wednesday that their efforts to fight climate change are far from enough to meet their stated goal of limiting global warming to 2 degrees Celsius (3.6 Fahrenheit). The report by the U.N. Environment Program, released just days ahead of a major climate conference, said the concentration of heat-trapping greenhouse gases like carbon dioxide in the atmosphere is up about 20 percent since 2000. Scientists say those emissions are contributing to climate change and that failure to contain them could have dangerous consequences, including rising sea levels inundating coastal cities, dramatic shifts in rainfall disrupting agriculture and drinking water, the spread of diseases and the extinction of species..."

Climate Change: Natural Disasters Made History In 2011. The story from irinnews.org; here's a clip: "Many of the worst natural disasters of 2011 were also the most severe the affected countries had ever experienced, revealed the Global Climate Risk Index (CRI) 2013, which was released in Doha on 27 November. Brazil, Cambodia, El Salvador,Laos and Thailand appear in the CRI’s 10 most-affected countries; all recorded their severest natural hazards-related catastrophes in 2011. Floods and landslides claimed the lives of more than 1,000 people and caused almost US$5 billion in direct losses in Brazil, said the index, which is produced by the NGO Germanwatch. Thailand is listed as 2011’s most natural disaster-affected country. The country experienced its worst flooding ever that year, triggered by the landfall of Tropical Storm Nock-ten. The flooding led to losses worth $43 billion, making it one of the most costly natural disasters of the world..."
