Long Overdue Spring Fling! (Fargo flood update; brief winter relapse late next week?)

72 F. high in the Twin Cities Saturday.
63 F. average high on April 26.
56 F. high on April 26, 2012.

31.7" snow in the metro area since March 1.

3 days of 70+ temperatures? The last time that happened was October 1-3, 2012.



Welcome Spring Fling

Minnesotans EARN their springs. 2013 could be a poster child for crazy extremes: from 5-inch snows to 70s in 4 days? Impressive. Time to clean up the yard, drag out the lawn chairs, remove stubborn doggy deposits and banish my coats and long johns to cold storage.

The icing on the cake? I may rest my 21 foot Malibu on the surface of my icy lake....and try to be patient.

With highs over 70 today, Sunday and Tuesday ice should break up on metro lakes next week. I can only hope Governor Dayton enjoys ice fishing - I'm not at all convinced ice will be off the Park Rapids Lakes by May 9.

Always have a viable Plan B, right?

Today will be the day you've been day-dreaming about since November: blue sky, 71-74F, a gentle southwest breeze, no humidity, few bugs & allergies under control. About as good as it gets.

A weak cool front ignites T-storms by Sunday night but most of the weekend looks dry. A warm front surges north Tuesday; highs near 80F. Soak it all up because a temperature tumble arrives midweek; 40s by Wednesday.

Expect shorts, t-shirts & random convertible sightings this weekend, but keep a heavy jacket handy.
I almost forgot: the ECMWF hints at rain by Wednesday - mixing with wet snow next Thursday.

I'm not joking.

Warm Into Tuesday, Then Another March-like Slap? Expect low to mid 70s today, a bit warmer Sunday, highs may reach 75-80F on Tuesday before dropping off a cliff by Wednesday behind a vigorous cold front. A blocking pattern causes next week's storm to stall, a southern surge of moisture may produce rain changing to wet snow next Thursday - although it's way too early for specifics. Some improvement is likely by next weekend. Deep breaths.

A Very Un-Maylike Weather Map. The ECMWF model map valid next Thursday evening shows another surge of chilly, Canadian air stalling over the Plains, pulling Gulf moisture right up the Mississippi River Valley into Minnesota and Wisconsin. There may be enough cold air in place for rain mixing with or changing to some wet snow by late Thursday or Thursday night. Timing and amounts are very much up in the air. The "Euro" also shows an unusually strong storm over Florida, forecast to churn up into the Carolinas with heavy rains, high winds and possible coastal flooding. Odd for early May. Map: WSI.

Back On Track. After a possible wintry relapse late next week the GFS shows slow moderation next weekend, 60s returning just in time for the 2013 Fishing Opener. Ice will be off most lakes from the metro to Mille Lacs by then, but Park Rapids and northern lakes? Probably not. Ice fishing anyone?

Watching The Red River Carefully. Flood Warnings are posted for the Red River now, a Flood Watch for northwestern Minnesota and northeastern North Dakota for rapidly melting snow and ice dams causing sudden rises in streams and rivers. The NOAA forecast for Fargo (upper right) shows a crest near 38 feet next Thursday, just 2 feet shy of the all-time record set in 2009.

Latest Flood Conditions. NOAA has a slick interface that allows you to see, at a glance, which streams and rivers are near or above flood stage - click on the individual marker and you get details; a prediction of when the river will crest, and how high.

Major Flooding At Wahpeton. The Red River is forecast to crest in Wahpeton later today, about 1 foot above major flood stage, but well shy of the previous record of 19.4 feet. Source: NOAA.


Effects Of Midwest Flooding Will Be Felt For Months. NBC News has a good overview of the problems, including a wild swing from not enough water in the Mississippi River a couple months ago to severe flooding in recent days; here's an excerpt: "...To the north, a damaged lock may keep a stretch of the Illinois River closed to commercial shipping traffic for weeks, the U.S. Army Corps of Engineers said. Flooding has halted the transport of corn and soybean barges at certain terminals on the river, Reuters reports. The disruptions could cause significant disruptions in the flow of grain and corn in the second-highest soybean producing state. Reuters reports almost 60 percent of U.S. grain exports are transported on the Mississippi River and its tributaries. Grain prices at export terminals at the Gulf of Mexico climbed this week to the highest level in at least a month due to the disruptions..."

Up To 375 Flood Gauges To Turn Off Because Of Fund Cuts. Doyle Rice from USA Today has a head-shaking story, another victim of "The Sequester". Coming at a good time huh? Here's an excerpt: "Just in time for the spring flood season, the federal sequester is threatening to shut off funding for hundreds of stream gauges used by the U.S. Geological Survey to predict and monitor flood levels across the country. "The USGS will discontinue operation of up to 375 stream gauges nationwide due to budget cuts as a result of sequestration," the USGS notes on its website. Additional stream gauges may be affected if USGS partners at state and local agencies reduce their funding support..."

NOAA's National Weather Service Completes Doppler Radar Upgrades. New "dual-pol" Doppler upgrades do a better job calculating precipitation types and rainfall and snowfall amounts - so sensitive they can even detect the debris signature from a tornado on the ground. More details from NOAA: "This week, the National Weather Service completed the dual-polarization technology update in Brownsville, Texas – concluding the 122 NWS radar site upgrades throughout the country. This new advanced technology is helping federal weather forecasters more accurately track, assess and warn the public of approaching high-impact weather. Dual-polarization is the most significant enhancement made to the nation’s federal weather radar system since Doppler technology was first installed in the early 1990s. Dual-pol radar sends and receives both horizontal and vertical pulses, which produces a much more informative picture of the size and shape of the objects in the sky. This provides meteorologists the ability to distinguish between rain, snow, hail and non-weather items like wildfire smoke plumes, birds and insects. Conventional Doppler radar only has a one-dimensional view making it difficult to tell the type of precipitation or object in the sky..."

In Pictures: Top 10 Greenest Buildings In the U.S. Here's a clip from an interesting story at gizmag.com: "The American Institute of Architects announced its top ten green buildings in the US for 2013 on Monday (Earth Day, uncoincidentally). It's a diverse list, containing a cheese factory, senior citizens' apartments, school buildings, and a smattering of LEED certificates. There's only one net zero building on the list, though it's worth remembering that it's much easier to build a net zero home than it is a net zero office or factory. Step inside for a short profile of each of the buildings, or head straight to the gallery for the architectural eye candy..."

Least Stressful States In The USA? Minnesota didn't make the Top 10 Stressful states, and it didn't make the Bottom 10 (most stressful states). Want less stress? Move to Iowa. Hawaii I get, but Iowa? Here's an excerpt from an article at gallup.com

WASHINGTON, D.C. -- Hawaii residents remained the least likely in the U.S. to say they felt stressed on any given day in 2012, at 32.1%. West Virginia residents, on average, were the most likely to report feeling stress, at 47.1%.

Climate Stories...


The Drought-Stricken Midwest's Floods: Is This What Climate Change Looks Like? Here'san excerpt from a story at The Atlantic Wire: "...In other words, a warmer atmosphere from climate change likely yields greater extremes in weather. This syncs with the draft report issued by the government's National Climate Assessment Development Advisory Committee last year. That report predicted the following for the Midwest: "longer growing seasons and rising carbon dioxide levels will increase yields of some crops, though those benefits will be increasingly offset by the occurrence of extreme events such as heat waves, droughts, and floods." That prediction was meant to be borne out over the next several decades. What it predicted, though, has already been seen over the course of six months..." (photo: AP).

As CO2 Concentrations Near Ominous Benchmark, Daily Updates Begin. Scientific American has the story - here's an excerpt: "...Scientist Ralph Keeling wants this generation to remember when atmospheric concentrations of carbon dioxide reached 400 parts per million, because of humans. "I hope that many people out there in the decades to come will say, 'Gosh, I will remember when it crossed 400,'" he said. That's why Keeling and his employer, the Scripps Institution of Oceanography at the University of California, San Diego, have launched a website that will provide daily updates on atmospheric CO2 concentrations, measured at Hawaii's Mauna Loa Observatory..."

CO2 On Trial: If Things Had Worked Out Better. Here's an excerpt of an important article, an explanation of how climate science has been turned into a perverse mock "trial". Michael Tobis argues that we need to grow up, and recognize our limits in this story at medium.com: "...The fact is that we are entering an age of new and unprecedented limits. We can still have a happy future, human achievement and human dignity can continue its broad historical progress, and we can still have a lot of fun. But we have to recognize new limitations. The emergence of limits is unfortunate. It's costly. It's ill-timed. But preserving a stable environment is an ethical responsibility like none that has preceded it. We need people to understand not only that CO2 is a global problem, but that it's just the first in a series, as we make the transition from an open frontier world to spaceship earth. As a brand of soap, this is a hard sell. We have to sell the idea of a widespread set of changes in behavior, a new set of ethical constraints, and a substantial increase in the complexity and scale of governance. There are serious risks and costs involved, but avoiding this responsibility will yield something much worse..."

Global Warming Accelerated Last 15 Years. Here's an excerpt from Doug Craig's terrific Climate of Change blog at Redding.com: "...And a new study of ocean warming published last month in Geophysical Research Letters by Balmaseda, Trenberth, and Källén reached several conclusions:

• Completely contrary to the popular contrarian myth, global warming has accelerated, with more overall global warming in the past 15 years than the prior 15 years. This is because about 90% of overall global warming goes into heating the oceans, and the oceans have been warming dramatically.

• As suspected, much of the 'missing heat' Kevin Trenberth previously talked about has been found in the deep oceans. Consistent with the results of Nuccitelli et al. (2012), this study finds that 30% of the ocean warming over the past decade has occurred in the deeper oceans below 700 meters, which they note is unprecedented over at least the past half century..."

Obama Campaign Launches Campaign To Shame Climate Skeptics In Congress. Here's the intro from a story at The Guardian: "The campaign group formed to support Barack Obama's political agenda has launched an initiative to shame members of Congress who deny the science behind climate change. In an email to supporters on Thursday, Organizing for Action said it was time to call out members of Congress who deny the existence of climate change, saying they had blocked efforts to avoid its most catastrophic consequences. The email linked to a video mocking Republicans who reject the science on climate change. "Right now, way too many lawmakers in Washington flat-out refuse to face the facts when it comes to climate change," Jon Carson, executive director of Organizing for Action wrote in the email. "We're never going to make real progress on this issue unless members of Congress get serious..."
