The Weather BlogDaily weather updates
Is this going to be another one of THOSE winters, where snow lovers grovel, beg & plead for a few lousy inches of Minnesota powder? Not sure, and it’s probably a little early to panic. December is, in theory, the second snowiest month of the year. 1981-2010 climate data shows an average of 11.5 inches of snow falls this month. So far the metro area has picked up 3-4 inches.
84-Hour Snowfall Potential. NOAA’s 12 km NAM shows the heaviest snow bands with Friday’s clipper from eastern North Dakota and northern Minnesota into the U.P. of Michigan. Amounts will be enhanced by lake effect into the weekend. Snowfall prediction by Sunday morning courtesy of Tropicaltidbits.com.
Geminid Meteor Shower Peaks. Details from IMO, The International Meteor Organization: “The Geminid meteor shower is the favorite of most meteor observers as it usually provides the strongest display of the year. On the peak night (December 13/14) between the hours of 1:00 and 2:00am local standard time (LST), an observer located in mid-northern latitudes under clear skies has the opportunity to view at least 75 Geminid meteors. If you watch from a rural setting far from city lights then your counts could exceed 100. If watching from urban locations you will be limited to around 50 meteors during this period. The Geminids are one of the few annual meteor showers that are active all night long…”
- One out of five falls causes a serious injury such as broken bones or a head injury.
- Each year, 2.8 million older people are treated in emergency departments for fall injuries.
- Over 800,000 patients a year are hospitalized because of a fall injury, most often because of a head injury or hip fracture.
- Each year at least 300,000 older people are hospitalized for hip fractures.
- More than 95% of hip fractures are caused by falling, usually by falling sideways.
- Falls are the most common cause of traumatic brain injuries (TBI).
- Adjusted for inflation, the direct medical costs for fall injuries are $31 billion annually. Hospital costs account for two-thirds of the total...”
Praedictix Briefing: Issued Wednesday, December 13th, 2017
- Multiple major wildfires continue across parts of southern California Wednesday morning, with over 262,000 acres consumed since last week.

- The Liberty Fire burned 300 acres and is 100% contained. The city of Murrieta has more information.
- Elevated fire danger continues today across southern California, with wind gusts up to 40 mph expected. Critical fire danger is expected Thursday, as wind gusts increase to 50 mph. Red Flag Warnings and Fire Weather Watches are in effect through Thursday across these areas.
- In the Great Lakes region, a clipper system will bring the potential of heavy snow today into Thursday to some areas. Detroit is expected to see over a half a foot of snow. Winter Storm Warnings are in effect.
Ongoing Wildfires. Four major wildfires continue to burn across southern California this morning. The Thomas Fire has grown to 236,000 acres burned and is 25% contained. Here was the situation on the fire from the Cal Fire incident report last night:
Extreme fire behavior oscillating between wind – and plume – driven runs will continue to hamper control efforts. Firefighters will remain engaged in structure defense operations and scout for opportunities to establish direct perimeter control. Fire will continue to threaten the communities of Santa Barbara, Carpinteria, Summerland, Montecito and surrounding areas. Fireline construction to the north of these communities will continue. Improvement of the Camino Cielo for use as a control line will continue. Contingency groups will improve existing fuel breaks in Santa Barbara County, particularly in the areas of Windy Point and Foothills. Direct line construction, where possible, will continue on the northern side of the fire as well as the establishment of secondary line. In previously burned areas, continued mop -up operations will occur in order to expedite repopulation efforts. The area between Fillmore and Ventura along Highway 126 will remain in patrol status. Strengthening of firelines around the Ojai Valley area will continue, as communities will remain threatened by resi dual hot spots. In the east, outlying areas of Fillmore will remain threatened. Fire personnel will work to construct direct fireline with the support of aerial resources where possible on the east side of the fire. Scouting for establishment of indirect fireline will continue where needed.
Elevated Fire Danger Continues Today. Santa Ana winds continue across southern California today, with low humidity values and wind gusts up to 40 mph. This will lead to another day of elevated fire weather concerns across the region. Elevated fire concerns extend into the Sierra as well, mainly due to low humidity values being transported west from the Great Basin. Wind speeds will generally be around 10 mph in the Sierra.
Critical Fire Danger Thursday. The weather pattern changes as we head into Thursday as a system moves into Arizona. However, this will strengthen the winds across southern California Thursday. Wind gusts will be up to 50 mph across the region and that – combined with low humidity values – will lead to critical fire weather conditions.
Red Flag Warnings And Fire Weather Watches. Due to the continued fire weather conditions – including gusty Santa Ana winds and low humidity values – Red Flag Warnings are in effect for:
- The Los Angeles/Ventura County Mountains, Santa Monica Mountains and Santa Clarita Valley through Friday morning. In these areas, winds will gust to 40 mph today and to 50 mph Thursday.
- Parts of the Sierra Nevada (including Yosemite) and Kern County Mountains through this evening. In these areas, the main concern is the low humidity values that would allow fires to quickly spread.
Fire Weather Watches are in effect Thursday into Thursday Night for the Los Angeles and Ventura county coasts, the San Fernando Valley, the Colorado River Valley and parts of San Bernardino, Riverside, Orange and San Diego counties. Wind gusts are expected to be between 40-50 mph tomorrow, with occasional gusts to 65 mph across southern California.
Latest Information From The National Weather Service – Los Angeles. Here is more information on the Red Flag Warning areas and expected fire weather over the next couple of days from the National Weather Service office in Los Angeles: “Gusty northeast winds are expected to continue through much of this week, especially over Ventura and Los Angeles Counties. Relative humidities will continue to remain in single or low teens as well with poor overnight recoveries. The gusty offshore winds, very low relative humidity, unseasonably warm temperatures, and extremely dry fuels will allow the extreme fire danger to continue. The greatest concern will be for the mountains of Los Angeles and Ventura Counties, the Santa Clarita Valley, and the Santa Ana wind prone areas of the Ventura County valleys and Oxnard Plain. Gusts up to 30 to 40 mph can be expected through Wednesday, then increase to 40 to 50 mph by early Thursday. These conditions will bring the potential for large fires, rapid fire growth, and extreme fire behavior if ignition occurs. Although there are no Red Flag Warnings issued for Santa Barbara County, there will be local north to northeast winds 15 to 25 mph around the hills above Montecito over the next couple of evenings bringing some elevated fire concerns.”
Smoke Impacts Continue. Poor air quality is once again expected today across the region due to the smoke from the Thomas Fire. This is the near-ground smoke forecast for Noon today.
Heavy Great Lakes Snow. A clipper system moving through the upper Midwest and Great Lakes over the next 24 hours will produce the potential of heavy snow as it moves through. Snow accumulations of 6-9” will be possible from Green Bay, WI, across central Michigan, including Detroit, by Thursday morning. Areas like Detroit, Cleveland and Pittsburgh will likely see impacts to the evening commute due to the snow.
Advisories And Warnings. Due to the potential of heavy snowfall amounts as this clipper moves through, Winter Storm Warnings have been issued for parts of Michigan, including Detroit.

California Wildfires By The Numbers. The most expensive year on record for wildfires? CNN.com has the story.
Unfettered Building, Scant Oversight Add to Cost of Hurricanes In U.S. Reuters investigates: “…Across the country, newer construction in flood-prone areas generated more than $9 billion in claims for structural damage on the cash-strapped flood insurance program between 2000 and 2015. Flood-management authorities say that some of those claims probably never would have been filed had proper building controls and accurate flood maps been in place. “You look at the media images and you see new subdivisions, new strip malls and new buildings with water up to the rooftop. Those are red flags in my mind. Those shouldn’t be happening,” said Paul Osman, floodplain program manager for the Illinois Office of Water Resources. Controlling construction inside flood-prone areas is critical to keeping flood insurance affordable and reducing post-disaster costs, federal officials say…”

The Loss of Arctic Sea Ice Cover Could Affect Millions Worldwide. Turns out what happens in the Arctic doesn’t stay in the Arctic. A story at Futurism connects the dots: “…Far from just being bad news for polar bears or vulnerable island chains, melting Arctic sea ice caps can affect areas a long way from the Arctic region, bringing not only higher sea levels, but also severe drought. This may be the case for California, which could see its already extreme lack of water getting worse in the coming decades, according to researchers at the Lawrence Livermore National Laboratory. In a study published on November 5 in Nature Communications, climatologist Ivana Cvijanovic and her team found that shrinking glaciers in the Arctic can modify atmospheric temperatures over the tropical Pacific. In turn, this heat imbalance can push rain-rich clouds away from California towards Alaska and Canada...”

Alaska Weather Service Cuts Balloon Launches Due to Staffing. U.S. News has an update on a development that may, in theory, impact forecast accuracy thousands of miles downwind, over the Lower 48 states: “Workers at 13 Alaska sites are supposed to release balloons twice a day that collect data on temperature, pressure and wind, but the National Weather Service has reduced weather balloon launches in rural Alaska, affecting the quality of forecasts. Launches have been limited in recent years by staffing shortages and by an overtime policy change in August, the Fairbanks Daily News-Miner reported . The Weather Service has launched 28 percent fewer balloons at six of the remote sites in order to keep employees to a 40-hour work week. The loss of any input data affects weather models, but the degree it hurts the accuracy of forecasts isn’t easy to quantify. The Weather Service supplements data from weather balloons with data from satellites, Weather Service Alaska Region Director Carven Scott said…”
How The Way We Think About the World Failed. No, more stuff does not equal more happiness or contentment. Here’s an excerpt of an eye-opening post at Eudaimonia and Co: “…Only a minority of people feel their lives are better today than they might have been fifty years ago. In response, the intellectuals I follow tweeted something like: “these foolish people! Don’t they know how good they have it! They should be happy!! What’s wrong with them?!” Their words dripped with the strange hallmark of what passes for thought today: hubris, arrogance, pride, and derision. Fascism, authoritarianism, and tyranny can only really arise when our institutions fail, and among the most important of these is the way we think. It’s no overstatement to say today that thought itself has failed — witness daily the constant, perpetual surprise outrage of pundits and intellectuals, whose inability to explain or predict the world anymore is expressed in a furious anger which soon turns to disdain...”

216 Companies on the Fortune 500 List Were Founded by Immigrants or Their Children. Here are a couple of clips from Quartz: “…Of the companies that made the list in 2017, 43% were founded by an immigrant or the child of an immigrant, according to research from the Center for American Entrepreneurship. The share of immigrant founders in technology is even higher, 45%—though there are immigrant entrepreneurs are represented in every sector… People born in other countries and their children have continued to feed the Fortune 500 list in more recent decades. Apple founder Steve Jobs, the son of a Syrian immigrant, and Russia-born Sergey Brin from Google—and its parent Alphabet—are among the most famous. But there are other relatively new companies with immigrant ties. Marc Randolph, one of Netflix’s founders, is the son of an Austrian immigrant. Sol Barer, a German immigrant, helped start biotech firm Celgene…”
How Tech Companies Could Keep the Workforce Alive. Think your job is safe from automation and AI? A story at The Atlantic caught my eye: “…Jobs in industries such as food services, transportation, and retail trade are at high risk of being automated, forcing workers to gain new skills to compete for well-paying jobs. From Google’s self-driving cars to Apple’s communication technology to Amazon’s retail model, automation is becoming more and more pervasive. As communities across the U.S. witness growing gaps between the skills that workers have and the ones that employers need, workers will need training. Debate about how to prepare workers for the future has largely focused on what educators and employers are doing and could do more of...”

Google’s True Origin Partly Lies in CIA and NSA Research Grants for Mass Surveillance. Lovely. Quartz has the story: “Two decades ago, the US intelligence community worked closely with Silicon Valley in an effort to track citizens in cyberspace. And Google is at the heart of that origin story. Some of the research that led to Google’s ambitious creation was funded and coordinated by a research group established by the intelligence community to find ways to track individuals and groups online. The intelligence community hoped that the nation’s leading computer scientists could take non-classified information and user data, combine it with what would become known as the internet, and begin to create for-profit, commercial enterprises to suit the needs of both the intelligence community and the public. They hoped to direct the supercomputing revolution from the start in order to make sense of what millions of human beings did inside this digital information network. That collaboration has made a comprehensive public-private mass surveillance state possible today…”
For the Good of Society – and Traffic – Delete Your Map App! So says the author of a story at nymag.com: “…Bayen points out that this is sort of a gigantic version of the prisoner’s dilemma. “If everybody’s doing the selfish thing, it’s bad for society,” says Bayen. “That’s what’s happening here.” Even though the app makes the route quicker for the user, that’s only in relation to other drivers not using the app, not to their previous drives. Now, because everyone is using the app, everyone’s drive-times are longer compared to the past. “These algorithms are not meant to improve traffic, they’re meant to steer motorists to their fastest path,” he says. “They will give hundreds of people the shortest paths, but they won’t compute for the consequences of those shortest paths...”
Family Sends the Most Awkward Christmas Cards for 15 Years, and It’s Too Funny. After seeing this post at Bored Panda I have to agree: “If you think you’ve already seen the funniest family Christmas card of the season, think again. Every year since 2003, the Bergeron family has been ringing in the holidays by producing the most clever and hilarious greeting cards we’ve ever seen, and just like the snow outside, they’re showing no signs of stopping. Mike Bergeron, his wife Laura, and their two daughters known online as ‘Gigi’ and ‘Juju’ have made an annual tradition out of the refreshingly original photoshoots, and each December, they choose a new knee-slapping theme. Whether they draw on pop culture, local culture, or embarrassingly awkward family cards of yore, they always seem to pull it off as a team. Special credit is due, of course, to the JC Penney Portrait Studio, which has seen them all the way from ‘white trash Christmas’ to a full drag ensemble...”
Andrew Zimmern Heads Up Minneapolis Food Hall. GoMN has the tantalizing details: “Minnesota’s culinary king has signed on as the first tenant of The Dayton’s Project – a $250 million makeover of the historic Dayton’s building on Nicollet Mall that, when finished, will include offices, retail stores, a gym, a library and the food hall. According to a press release from developers, The Dayton’s Food Hall and Market will be a “mix of well-known food vendors, local treasures, fresh food purveyors, and food makers creating a market that will be the first of its kind in the Twin Cities…Zimmern is hoping to create a food adventure similar to many European food halls and markets, where visitors can sample food from local vendors and shop for things like fresh meat and seafood, artisanal cheeses and fresh baked goods from local purveyors…”

Climate Change to Affect City and State Credit Ratings. Here is an excerpt from an Op-Ed from San Antonio’s Express-News Editorial Board: “Cities and states, take note. Climate inaction could lower your credit rating. A recent report from Moody’s explains how the rating agency will assess climate change risk for states and cities. Risk indicators include economic activity along the coast, potential for hurricane and other extreme-weather damage, and the number of homes in a floodplain. Moody’s didn’t identify cities in its report, but Texas is one of the states deemed most vulnerable to climate change. Not surprising since Texas has tremendous economic activity along the Gulf Coast and is prone to all sorts of extreme weather across the state. Hurricane Harvey, which slammed into the Coastal Bend before dumping more more than 50 inches of rain on Houston, has caused an estimated $180 billion in damages. Many of the properties damaged were not in designated floodplains, raising questions about whether our mapping and flooding expectations are accurate in light of climate change…”

Warm Arctic is ‘New Normal,’ Scientists Say: Here’s a summary and link to relevant stories from Climate Nexus: “The Arctic is experiencing “unprecedented” warming with a rate of sea ice decline not seen in at least the last 1,500 years, a new government report shows. The National Oceanic and Atmospheric Administration’s annual Arctic Report Card, released Tuesday, shows that the region is warming around twice as fast as the rest of the planet. The report also shows that thicker ice lasting through multiple melt seasons only made up 21 percent of total Arctic ice this year, as opposed to 45 percent in 1985. The report states that the Arctic “shows no sign of returning to the reliably frozen region it was decades ago.” (AP, Washington Post $, The Guardian, BBC, Axios, USA Today, NPR, InsideClimate News, Earther, Mother Jones, The Hill)

EXTREME WEATHER: More perspective and context from Climate Nexus Hot News: How much did climate change affect California’s wildfires? Depends on where you are (Vox), why are California’s wildfires so historic? For starters, a diablo is at work (Washington Post $), a year punctuated by tragedy (WSJ $), this city in Alaska is warming so fast, algorithms removed the data because it seemed unreal (Washington Post $), from floods to fires, US weather went to extremes in 2017 (USA Today)
Did Climate Change Worsen the Southern California Fires? A warmer, drier climate was one of multiple reasons why the fires have been so bad, according to a story at The Atlantic: “…The answer isn’t as clear-cut as it was this summer, when drought- and heat-stoked fires raged across the Rockies and Pacific Northwest. Instead, a mix of forces are driving the fires in Southern California, and only some of them have a clear connection to global warming. “These fires are not immediately emblematic of climate change,” said John Abatzoglou, an associate professor of geography and climate at the University of Idaho, in an email. “Yes, California did have the warmest summer on record. But the big anomaly here is the delay in the onset of precipitation for the southland that has kept the vegetation dry and fire-prone.” In other words, late-fall and winter rains would normally end California’s fire season in November. Because those rains haven’t yet arrived, the blazes continue…”
Judges Push Trump Lawyers in Kids’ Climate Suit Hearing: From Climate Nexus Hot News: “Federal judges expressed doubt on Monday at the Trump administration’s attempt to toss out a lawsuit brought against the US government by a group of 21 young people suing over climate change. The three-judge panel of the 9th Circuit Court of Appeals in San Francisco heard arguments from the Trump administration, which had made a rare request for the appeals court to halt the Juliana v. United States case, which is scheduled to go to trial in February. While administration lawyers argued that the “unprecedented” case would create a “constitutional confrontation” if allowed to proceed, multiple outlets report that the judges’ line of questioning seemed to indicate that they will allow the case to move forward. “If we don’t stop climate change, I might not have a home when I’m older,” 10-year-old plaintiff Levi Draheim, a Florida resident, told the court. “That’s why our case has to go to trial.” (San Francisco Chronicle, Washington Post $, Reuters, Bloomberg, InsideClimate News, Buzzfeed, ThinkProgress, Mashable, Mercury News, Vox, Climate Liability News, Washington Examiner, The Hill, KQED)
