Cold Rain Ends As Slush Tonight (plowable far north metro)

Posted by: Paul Douglas under Lions Updated: April 16, 2014 - 8:16 AM


Our tormented April limps on: brief, wondrous spasms of warmth, interrupted by extended spells of wind chill & fat flakes. By the time mid-April rolls around Minnesotans do NOT want to hear about "shovel-able snows".

With a higher sun angle and temperatures above 32F in the metro most roads should remain wet, in spite of a sloppy mix. We can't rule out a coating of slush in the metro area, especially early this morning, with an inch or two north metro. If you're driving north up I-35 travel conditions should get progressively worse; mainly snow north of Monticello, Princeton and North Branch. Some 3-7+ inch amounts are possible by evening from central Minnesota and the far northern suburbs of MSP into northern Wisconsin.

Keep those driveway stakes in a little bit longer.

I expect a "snow sandwich"; precipitation starting as a coating to 1 inch of slush this morning, changing to rain, then back to snow at the tail-end of the storm by this evening. Winds reach 25 mph, creating treacherous travel up north, along with enough snow to build a respectable slush-man from Brainerd and Duluth to Hayward.

Lovely.

Any primal screams today give way to contented sighs next week, with highs in the 60s again next week, with definite hints of spring as early as Easter Sunday.

Easter egg hunts may be muddy this year; rain is likely Saturday into Easter Sunday. Good news for your greening garden.


Latest WRF Run. Latest guidance shifts the heaviest snow band well north of MSP today and tonight, a few inches for St. Cloud and Brainerd, with as much as 8-12" from near Crosby and Aitkin to Duluth by Thursday morning. Source: HopWRF.


On Edge. There's little doubt that the heaviest amounts of snow will fall north of MSP later today and tonight. Today's storm should pull enough warm air aloft for mostly rain midday and afternoon from the Twin Cities on south to the Iowa border, but even in the immediate metro a cold rain probably ends as an inch or two of slush. Northern suburbs may pick up a few inches of slush, with the heaviest amounts far north metro, where some 3-7" amounts can't be ruled out by Thursday morning. More details on the Winter Storm Warning from NOAA.


A Light At The End Of Our Cold, Snowy Tunnel. April is a volatile, fickle month - everything from blizzards and floods to tornadoes. After another winter tantrum later today and tonight skies begin to clear Thursday. ECMWF guidance suggests 60s by Easter Sunday, with a rerun of spring much of next week. That would be nice. Graphic: Weatherspark.


Precipitation Needed To End Drought. Here are the latest numbers from NOAA NCDC; as much as 20" or more of rain necessary to break the drought from California's Central Valley southward to San Diego.


Tornado Season Is Off To A Slow Start, But There's No Predicting What's Next. Matt Lanza has a very good summary of the (relatively) quiet start to tornado season, nationwide, and what may be driving the low numbers. Here's an excerpt from his story at FiveThirtyEight Science: "Tornado season has started quietly this year, continuing a trend that began in 2012. Through March 31, the United States had only 70 reported tornadoes even though the first quarter has averaged more than 170 a year over the last 10 years. April has remained quiet, with 36 preliminary tornado reports as of Sunday. Oklahoma hasn’t seen an intense tornado1 since May 31, the longest such stretch on record. The small tornado seen there on Sunday was the first of any kind since Aug. 7..."


March Was 4th Warmest on Record Globally. Here are a couple of excerpts from a post at Climate Central: "...March 2014 was the fourth-warmest March on record globally, according to recently released NASA data, making it the 349th month — more than 29 years — in which global temperatures were above the historic average...This warm March follows on the heels of the announcements that this winter was the eighth warmest globally and that 2013 was anywhere from the fourth- to the seventh-warmest year on record, depending on which data set is used."

If El Nino Comes This Year, It Could Be A Monster. Wired.com has the story; here's the introduction: "Attention, weather superfans: El Niño might be coming back. And this time, we could be in for a big one. Official NOAA Climate Prediction Center estimates peg the odds of El Niño’s return at 50 percent, but many climate scientists think that is a lowball estimate. And there are several indications that if it materializes, this year’s El Niño could be massive, a lot like the 1997-98 event that was the strongest on record. “I think there’s no doubt that there’s an El Niño underway,” said climate scientist Kevin Trenberth of the U.S. National Center for Atmospheric Research. “The question is whether it’ll be a small or big one...”


A Significant El Nino Brewing? It's still early, but leading indicators suggest a substantial warming of equatorial Pacific Ocean water for the latter half of 2014. Data from the Australian Bureau of Meteorology show temperatures nearly 2F warmer than average in the Pacific by autumn: "All international climate models surveyed by the Bureau indicate that SSTs in the equatorial Pacific Ocean will continue to warm during autumn and winter. Almost all models indicate El Niño thresholds will be exceeded during the southern hemisphere winter."


Earth Dodges A Huge Magnetic Bullet. We've seen a number of close calls. If a Category 4-5 X-Class solar flare ever reaches Earth's surface we won't be talking (or communicating) much about weather annoyances. We'll have much bigger problems to contend with, possibly a widespread loss of satellite communication and the power grid. Here's an excerpt from Electronic Products: "I'd say electronic engineers have not been terribly worried about a solar event upsetting their designs. But maybe they should be worried. According to University of California, Berkeley, and Chinese researchers, a rapid succession of coronal mass ejections sent a pulse of magnetized plasma barreling into space and through Earth's orbit on July 23, 2012. Had the eruption come nine days earlier, when the ignition spot was aimed at Earth, it would have potentially wreaked havoc with the electrical grid, disabled satellites and GPS, and disrupted our increasingly electroniclives..."

Asian Air Pollution Strengthens Pacific Storms. Smog spiking storms hundreds, even thousands of miles downwind from the source? Here's an excerpt of a BBC article: "Air pollution in China and other Asian countries is having far-reaching impacts on weather patterns across the Northern Hemisphere, a study suggests. Researchers have found that pollutants are strengthening storms above the Pacific Ocean, which feeds into weather systems in other parts of the world. The effect was most pronounced during the winter..."

Fujitsu 3-D Tsunami Simulator Predicts Watery Disasters As They Unfold. Real-time predictions of tsunami impacts? Here's a clip from vr-zone.com: "Fujitsu’s collaboration with Touhoku University led to the development of a 3D tsunami simulator for high-precision tsunami forecasting....The 3D tsunami simulator can recreate how a tsunami flows inland in very accurate detail, showing the flow of water as it interacts with the general topography of the area it is going to affect. It can also simulate waves as it breaks and forms, and as it flows through obstacles like urban buildings and local coastal geographic features..."


Tornadoes And Hurricanes And Earthquakes - Oh My! Surviving A Disaster In Your Home. I picked up a few timely tips and valuable suggestions in this Living Green Magazine article from Ross Bishop; here's an excerpt: "...The lesson is, when the infrastructure goes, the one constant is that life can be extremely difficult. And even a little preparation can make a great deal of difference. Electricity is usually the first thing to go, and our lives today are very electric dependent. No electricity means no furnace, no lights, and no computer. It also means that the refrigerator won't run and that you won't be able to recharge your cell phone. Natural gas is more reliable, so you may have the stove for cooking (even if you have to light it by hand), and you may have hot water...."

The lesson is, when the infrastructure goes, the one constant is that life can be extremely difficult. And even a little preparation can make a great deal of difference.

Electricity is usually the first thing to go, and our lives today are very electric dependent. No electricity means no furnace, no lights, and no computer. It also means that the refrigerator won’t run and that you won’t be able to recharge your cell phone.

Natural gas is more reliable, so you may have the stove for cooking (even if you have to light it by hand), and you may have hot water. The furnace however, needs electricity.

A flood, hurricane or earthquake will put your water supply at risk. Even though you may have water, it may not be safe to drink. Depending on where you live, this may not happen very often, but the consequences are dire. You can go without food for a month if pushed, but without water, you’ll die in a matter of days.

Twin Cities Crack The Top 10 Greenest Cities In America. I found this interesting, and couldn't help noticing that St. Paul is slightly ahead of Minneapolis on the list, but nowhere close to Madison and Anchorage. Anchorage? Here's an excerpt from EcoWatch: "When a website creates a list with the title, “Greenest Cities in America,” it’s easy to think you know which ones will be included and why. NerdWallet’s list of that name does contain a couple overlapping municipalities with lists on the top solar cities or the most bike-friendly communities, for example, but it’s mostly comprised of cities that deserve far more recognition for their sustainable, environment-focused efforts. California is typically associated with being green, but not under the definition provided by NerdWallet, an informational finance site..."

Turns Out, You Can Make Solar Panels Work In Cloudy Cities. Here's another article that made me do a double-take; an excerpt from The Atlantic Cities: "Solar panels have always made sense in cities that get a lot of sun, at least intuitively. But in recent years, scientists have figured out ways to make them more useful for perpetually gloomy cities like London and Seattle. The solution comes down to organic photovoltaics. Unlike traditional solar panels, made of silicon, OPV cells are made of organic semiconductors, which can be 3D-printed or coated over large areas, as seen in the video below...."


What Riding On Airforce One Is Really Like. Here's an excerpt of an interesting behind-the-scenes story from The Washington Post: "...It turns out that riding Air Force One is, in lots of ways, like flying commercial. You need to get there hours early. You send your items through a metal detector and get wanded down. The inside of the cabin is, well, the cabin of a plane, but with some much nicer touches, like real towels and hand lotion in the bathroom..."

New Leak Points To Major iPhone 6 Design Overhaul. BGR has the latest on what may be coming next from Apple; here's an excerpt: "...Apple is rumored to launch at least one bigger iPhone model later this year, with various reports suggesting that a 4.7-inch iPhone 6 would hit stores first, at some point in late Q3. An even bigger 5.5-inch iPhone version has also been detailed in many reports, with recent ones implying that certain manufacturing issues may prevent Apple from launching it at the same time with the 4.7-inch iPhone..."

Amphicruiser: Amphibious 4WD Based On Toyota Land Cruiser. And who wouldn't want to be seen in one of these pulling up to Big Island on Lake Minnetonka on a busy Saturday afternoon? Here's a clip from Gizmag: "We wanted it to be as solid on water as the Land Cruiser is on land." That's Dutch Amfibious Transport co-founder Dirk-Jan de Jong talking about his company's heavy duty amphibious 4WD, the Amphibicruiser. Built around a Toyota Land Cruiser engine, it's a fully fledged on and offroad cruiser that can be driven up a river or out to sea with next to no training..."


World's First Cannabis Vending Machine Unveiled In Colorado. The Times of India has the mind-numbing details: "A dispensary in Colorado is making the most of the state's recent legalization of cannabis by introducting the world's first marijuana vending machines. The machine, called ZaZZZ, will work in a similar way to cigarette machines but includes new technology that requires would-be tokers to scan their driving license (or other, similar documentation) before they can access the goods..."


Weather Service: Please Disregard Our Giant Biblical Flood Warning. Yes, even NOAA has occasional issues with their web sites, as described in this clip from Mashable: "NOAA, meet Noah. The website for the National Weather Service (NWS), which is part of the National Oceanic and Atmospheric Administration (NOAA), suffered a major malfunction on Thursday leading to the false appearance of a biblical flood warning spanning from Canada (which the NWS doesn't even have responsibility over) south to Florida, and west to Michigan. The malfunction, which began around midday ET and was fixed by 3:15 pm ET, affected local NWS websites — key conduits for disseminating life-saving watches and warnings..."

Climate Stories....

Tracking Temperature Anomalies Since 1968. A friend shared this site with me yesterday, a fascinating look at national temperature trends over the last 50 years. Check out the Enigma Climate Data Engine for yourself: "Every day, the Global Historical Climatology Network collects temperatures from 90,000 weather stations. Dating back as far as the late 1700's, the records provide an incredible source of insight into our changing climate."


Climate Change Doubling Big Power Outages, Group Says. A story at The Columbus Dispatch caught my eye; here's an excerpt: "...The study from Climate Central says that severe weather caused 80 percent of the major outages from 2003 to 2013. A major outage is defined as one that affects at least 50,000 people or interrupts at least 300 megawatts; 1 megawatt can power about 1,000 homes. “Heat waves are hotter, heavy rain events are heavier, and winter storms have increased in both frequency and intensity,” the report says. “To date, these kinds of severe weather are among the leading causes of large-scale power outages in the United States.” The number of major outages was double that recorded during the prior 10-year period, though the author notes that reporting requirements have changed, which might be driving some of the increase..."

Canadian Economy Will Lose Billions To Climate Change: Report. Extreme droughts and floods, similar to what hit Calgary in 2013, may become the norm in the coming decades. Here's a clip from thestar.com: "A new report on the financial implications of climate change notes that while natural catastrophes are estimated to cost Canadians $21-$43 billion per year by 2050, popular economic measures like GDP fail to capture the escalation, discouraging preventative investment. The TD report follows a recent and alarming warning by the United Nations Intergovernmental Panel on Climate Change that governments are ill-prepared for a warming world. If action is not immediately taken, the UN report projected risks could become unmanageable..."

Rising Sun. Why don't we hear more about the ongoing solar power revolution in the popular media? Here's an excerpt of an Op-Ed from Paul Krugman at The New York Times: "...In fact, it’s possible that solar will displace coal even without special incentives. But we can’t count on that. What we do know is that it’s no longer remotely true that we need to keep burning coal to satisfy electricity demand. The way is open to a drastic reduction in emissions, at not very high cost. And that should make us optimistic about the future, right? I mean, all that stands in our way is prejudice, ignorance, and vested interests. Oh, wait..."
