Straight-Line Wind Damage. Good friend and former WCCO-TV anchor and reporter Don Shelby called me yesterday - he has a place up on Lake Ida near Alexandria, said traffic was blocked off in Glenwood and Kensington, due to downed trees and powerlines. Click here to see the complete run-down of damage from Monday's severe storms here.
A Month's Worth of Rain On Monday. NWS Doppler radar rainfall estimates show some 3-4" amounts near Alexandria and Glenwood (where there were numerous reports of straight-line wind damage. 1-3" amounts were common from Detroit Lakes into the Brainerd Lakes area, resulting in flash flood warnings over much of northern Minnesota Monday night.
Tuesday Severe Threat. Severe storms are possible from the Quad Cities of Iowa to Milwaukee, Chicago, Detroit and Cleveland later today, according to SPC.
Drippy Dew Points = More Severe T-storms. Other than being annoying (and potentially dangerous, especially for people who work out in the heat or don't have access to A/C) this summer's extraordinarily high dew points have helped to fuel unusually severe and persistent thunderstorms, drenching much of Minnesota with tropical-like downpours. Here's a post from the local NWS office:
"Dew point often directly correlates to deeper atmospheric moisture and instability, two parameters that are conducive for severe thunderstorms in the presence of some type of weather front. Thus meteorologists often look at dew point as one of the key elements in forecasting severe weather potential. Indeed, the dew point during some of the area's severe weather events this year was quite high, over 9° above the 2011 summer average so far."
Dew Point Trend. Dew points linger in the low 70s today, but dip into the 50s Wednesday (meaning half as much water in the air). More humid air returns later this week, 65-73 degree dew points from Thursday into the weekend.
July Heat In Washington D.C. Was Unprecedented. Here's an article summarizing the record heat in our nation's capital, courtesy of the Capital Weather Gang, reporting for the Washington Post: "Relentless and punishing, July’s heat was unrivaled in 140 years of Washington, D.C., weather record-keeping. The July temperature averaged 84.5 degrees at Reagan National Airport — Washington’s official weather station — more than a degree above July 2010 and July 1993, which previously held the mark for hottest month. July’s heat piled onto a torrent of recent hot-weather records and attained all sorts of unenviable hot-weather milestones. The high temperature was at least 90 on 25 occasions, the most on record. When the July 29 temperature hit 104 degrees, it was the highest reading since 105 on August 17, 1997, and it tied for the fifth-hottest in the books. On July 22, the heat index — a measure of the combined heat and humidity — reached 121 degrees, the highest level since 122 on July 16, 1980. Amazingly, the month also had eight record days for warm low temperatures, including seven when the temperature failed to fall below 80 degrees. Four of those days came consecutively (from July 21 to 24), the longest such stretch on record by two days. Twice (July 23 and 24) the District tied for its warmest all-time low temperature of 84 degrees. And the heat was off the charts at other weather stations in the region."

Deadly Tornado Hits City In Russia's Far East. Click here to see the video clip from rt.com: "One person has been killed and twenty eight others injured as a powerful tornado hit the Russian far-eastern city of Blagoveshchensk. The tornado was so powerful that it tore the roofs from houses, turned over vehicles, flattened trees and smashed windows in several buildings. Local authorities have introduced a state of emergency in the city, Itar-Tass news agency reports. 200 people and 50 vehicles are already involved in the cleaning operation."
"Shawshank Tree" Damaged By Thunderstorm. AccuWeather has the details: "The oak tree that was made famous by the movie The Shawshank Redemption was severely damaged by wind Friday afternoon. A thunderstorm moving through the area Friday at around 2:30 p.m. EDT produced straight-line winds that damaged the tree according to Mansfieldnewsjournal.com. The tree had a rotten center that weakened it. The storm caused a power outage and damage to other trees. The power was restored by 6 p.m. EDT. The oak tree is near the location where Andy, portrayed by Tim Robbins, hid his treasure. Since the movie, based on a short story by Stephen King, many people visit the tree and take photos, according to Mansfieldnewsjournal.com."
Wettest European Cities. Planning a vacation or business trip to Europe? If you're heading to Zurich you'd be well-advised to pack an umbrella, with an average of 42.3" rain/year. Here's a list of Europe's Top 10 Wettest Cities, courtesy of NOAA and NCDC.

Paul's Conservation Minnesota Outlook for the Twin Cities and all of Minnesota:
In The Flood Zone, But Astonished By High Water. Here's an excerpt of a New York Times story focusing on the incredible duration and intensity of the flooding on the Missouri River: "DAKOTA DUNES, S.D. — Some skeptical locals offered a warning when developers transformed this mostly barren peninsula at the intersection of two rivers into an exclusive planned community, complete with million-dollar homes and a private golf course designed by Arnold Palmer. They call it “the Dunes” for a reason, the warning went — the rivers put the sand there, and the rivers could sweep it away. But, much like the developers, the new residents were not worried. A few even paid a premium to be closest to the flowing water of the Missouri and the Big Sioux. Now, a little more than two decades later, the stately homes on Spyglass Circle and Pebble Beach Drive have been evacuated and the 18th hole is under six feet of water, as miles of newly built levees strain to keep this community from surrendering to a historic flood. Many residents here at the southeastern tip of the state, where it borders Nebraska and Iowa, say they never imagined this chain of events."
Recent Floods Shatter U.S.'s False Belief In Taming Rivers. The New York Times has the story - here's a brief excerpt: "DAKOTA DUNES, S.D. — Skeptical locals offered a warning when developers transformed a mostly barren peninsula at the intersection of two rivers into an exclusive planned community, complete with million-dollar homes and a golf course. They call it “the Dunes” for a reason: The rivers put the sand there, and the rivers could sweep it away. Now, a little more than two decades later, stately homes have been evacuated and the 18th hole is under water, as miles of newly built levees strain to keep this community from historic flooding. And now, some people are using the high waters from North Dakota to New Orleans to revisit longstanding questions about whether the very government programs designed to safeguard people from floods actually encourage them to take chances."

Army Corps Battles Perceptions In Missouri River Flood. Here's a USA Today story revolving around the politics (and inherent unpredictability) of flood forecasting: "SIOUX FALLS, S.D. — Jody Farhat had a problem. It was June 3, and the Army Corps of Engineers' water management chief for the Missouri River basin had just received word that contractors building a private levee in Dakota Dunes had been delayed. They needed the corps to postpone stepping up water releases from Gavins Point Dam -- pivot point in the battle between upper and lower basin interests on the Missouri River -- for an extra day. "Don't feel we have much choice here," Farhat wrote other corps officials. Brig. Gen. John McMahon, commander of the corps' Northwestern Division, replied soon after: "Roger. Thanks. This is a smart 'political' move IF it's supportable from a (water management) perspective." The next day, another official jumped on the email thread: "You know the politics -- We'll do what we need to do." They agreed that news of the schedule change should, for now, stay with the corps. "Of course, nothing public," engineer Paul Boyd wrote."
Twilight Of The Glaciers. Here's an excerpt of an important story in the New York Times: "AN hour or so up ahead, at the higher elevations along the trail that leads over Siyeh Pass, huckleberries were ripening. Even a dawdling day hiker like me knows that huckleberries can quickly mean grizzlies in Glacier National Park. I indulged a nervous tic and patted around for the loud red aerosol can on my belt, whose label reads Counter Assault. It’s effective as a bear repellent, but even more reliable at making an urbanite feel faintly ridiculous.
I was in northwest Montana for the hikes and the huckleberries, but most of all to experience the namesake glaciers, which, I had recently learned, might be around for only another decade or so. Given that a century and a half ago there were 150 and now there are 25, the trip makes me an enlistee in the practice known by a somewhat prickly term: last-chance tourism."

Obstacles To Capturing Carbon Gas. An informative article from the New York Times (subscription may be required): "BRUSSELS — Can the world use fossil fuels and protect the climate too? That is the goal of carbon capture and sequestration, which is a process for trapping carbon dioxide before it reaches the atmosphere and then pumping it underground, or under the seabed. The process is already used by oil and natural gas companies like BP and Statoil at sites like In Salah, Algeria. There, the carbon dioxide that exists along with natural gas is captured and stored onshore in a saline aquifer. Despite a tiny leak from a faulty wellhead valve four years ago, and despite the need to reduce the quantities of carbon dioxide injected because pressure had built up in the saline aquifer faster than expected, BP of Britain and Statoil of Norway said, millions of tons of the greenhouse gas have been prevented from reaching the atmosphere. Oil and natural gas companies also have trapped large amounts of carbon dioxide in the minute pores and spaces in rocks at similar projects in countries like Norway and Canada. But efforts to make the process, known as C.C.S., a mainstay of efforts by the power industry to go green are hitting obstacles." (graph courtesy of NOAA).
