41 F. high in the Twin Cities Saturday.
48 F. average high on March 28.

March 29, 1986: Record warmth with July-like temperatures. The Twin Cities hits 83.

Tornado Magnet
We live with risk; a dark potpourri of natural disaster threats that vary across the USA. Overall weather and climate risk is greatest in the southern USA, which hosts both tornado alley as well as hurricane alley. The safest major U.S. cities: San Diego, Albuquerque and Honolulu, but even here the risk from tremor, storm and wildfire isn’t zero.

People living in Moore, Oklahoma have to be wondering what’s going on. Last Wednesday’s EF-1 tornado strike was tame compared to the three monstrous (EF-5) tornadoes that have struck the suburb of Oklahoma City since 1998. The town is only 22 square miles in size, but according to meteorologist Brad Panovich it’s been struck by 12 tornadoes since 1950. An accident of geography? I wonder if the heat island of OKC might play a role spinning up more (major) tornadoes over Moore. Very odd.

A week ago today the southwest suburbs were treated to 9 inches of snow. Today the sky above our heads is warm enough for rain showers. 50s return by tomorrow; 60s midweek with a stray thunderclap before we cool off next weekend.

4 of the last 5 springs have been historically wet in Minnesota. Will history repeat itself again in 2015?

I doubt it.

There have been fewer tornadoes nationwide through the month of March than in the past 10 years. In Oklahoma, two years after deadly tornadoes ripped into the state’s midsection, there could be a second straight year of an uneventful tornado season. It’s part of what forecasters are calling a ‘tornado drought.’ (AP Photo/Kim Johnson Flodin, File).

Windblown Sunday. A fast-moving clipper sparks 35 mph wind gusts in the Twin Cities, but over central and western Minnesota winds may gust as high as 40-50 mph.

Sustained Winds Peak This Afternoon. Our suite of models show sustained winds reaching 22-30 mph by early and mid afternoon today, gusts as high as 40 mph in the Twin Cities. Source: Ham Weather.

Flirting With Spring Again Next Week. Temperatures top 50F today with windblown showers, but it starts to feel like spring again Monday into Thursday with a streak of 60s before temperatures cool down by the weekend. A few claps of thunder are possible Wednesday along the leading edge of cooler air.

Spring Fever Returns Next Week. GFS guidance suggests low 70s Wednesday; 60-degree plus weather likely Monday into Thursday of next week. Numbing cold and snow showers over the Northeast give way to moderating temperatures in the coming days; record to near-record warmth continues across the southwestern USA. GFS guidance: NOAA and HAM WEATHER.

Expanding Drought. 99% of Minnesota is abnormally dry, over 88% of the state in moderate drought. Unusually dry conditions stretch from the Dakotas to Wisconsin, with severe (perpetual) drought deepening across California, where it promises to be a long, dry, abnormally warm year. Pockets of extreme to exceptional drought are showing up from Oklahoma City to Wichita Falls, Texas.

Warmer Bias Returns in March. Dr. Mark Seeley provides perspective on a statewide basis; here’s an excerpt of WeatherTalk: “…It appears that March will wrap up bringing higher temperatures and more moisture the last few days of the month. Most observers will report a mean monthly temperature from 4 to 7 degrees F warmer than normal (mean values), and total precipitation that is less than normal. Extremes for the month were 78F at Browns Valley on the 15th and -40F at Cotton on the 5th, with the highest monthly precipitation value of close to 2 inches at Lanesboro…”

7 Years of Rain in Chile Desert Kills At Least 9. Here’s more information and a video, courtesy of weather.com: “Thunderstorms brought the equivalent of 7 years of rain to Chile’s Atacama desert region and caused deadly flooding Thursday.  Antofagasta, Chile, where the annual average precipitation is 0.13 inches, saw 0.9 inches of rain in 12 hours. “The Atacama Desert is an extremely arid region and has been for millions of years. As a result, the terrain is hard and rocky because rainfall isn’t frequent or abundant enough for either weathering rocks into sand or supporting the kind of ecosystem that would help turn rocks and minerals into soil. Without soil and plant cover to help absorb rainfall, it just runs off instantly as torrents of water,” weather.com senior meteorologist Nick Wiltgen said…”

Moore, Oklahoma: Tornado Magnet. The Washington Post’s Capital Weather Gang has a good summary of Wednesday’s tornado outbreak, and speculates on why the southern suburbs of Oklahoma City have been struck so often in recent years: “…Other than the fact it lies in the heart of tornado alley, there is no clear reason why Moore keeps getting hit by tornadoes. Studies have shown urban environments can sometimes enhance rain from thunderstorms downwind of cities (and Moore is just south of Oklahoma City), but little work has been done to determine if cities impact tornado formation...”

AccuWeather Rips National Weather Service For “Late Tornado Warning”. I had no idea AccuWeather was issuing their own warnings. You can read their write-up about the recent Moore EF-1 tornado and how they approached the storm here.

Advanced Warnings Questioned After Tornado. More complaints from Moore residents highlighted in the Norman Transcript.

Overshooting Tops. This high-resolution visible image from NOAA was taken as an EF-1 tornado formed over Moore, Oklahoma. If you look carefully you can see a line of knobs on top of the overshooting thunderstorm anvil tops, marking zones of extreme upward motion, where upward motion extended into the stratosphere.

Let’s Give Them Something To Tweet About – – Why Periscope Matters. Dave Pell at NextDraft takes a look at how the addition of live video streaming with Periscope in Twitter may turbocharge self-publishing. All those cat videos. Here’s an excerpt: “…That’s where Periscope comes in. Except in rare cases, these streamed events will not be global or even national in nature. But they will be live, we’ll know exactly who’s watching with us, and the content will be pushed through the same pipes that support our conversations around it. Live fodder for discussion and the discussion itself all on the same social network. To paraphrase the great Bonnie Raitt, Twitter had to give us something to Tweet about…”

Climate Stories…

Media Contributing to “Hope Gap” on Climate Change. Another reason why denial is in vogue with some people – a sense of malaise and hopelessness. There are solutions and we will figure out cleaner ways to keep the lights on and add new jobs. Here’s an excerpt from Climate Central “…Perhaps more provocatively, the results of the detailed analysis also suggest that newsrooms on both sides of the warming pond are struggling to produce stories about climate change in ways that are engaging for their audiences. Instead, they’re fueling senses of hopelessness on the issue. “I don’t find their major findings surprising,” Anthony Leiserowitz, director of the Yale Project on Climate Change Communication, said of the study, with which he was not involved. “We find in our audience research that even the alarmed [those most concerned about climate change] don’t really know what they can do individually, or what we can do collectively. We call this loosely ‘the hope gap,’ and it’s a serious problem...” (Photo: Lori Ryan).

Miami Beach at 100: The Sea Is Rising, So Are The Condos. Fusion has an interesting story – here’s an excerpt: “This past fall, the City of Miami Beach—one of America’s most famous beach resorts since it was founded 100 years ago this month—faced the King Tide. King Tide is an unscientific term for a particularly strong high tide. For Miami Beach residents, that typically means flooding, and lots of it. The city’s main arteries typically shut down for days at a time as 88,000 residents wait for the water to drain…”

Will Climate Change Drown The Party on Miami Beach? Rent, don’t buy. Here’s a link to a good video explainer from Fusion: “Miami Beach has been dubbed ground zero for the consequences of climate change, where rising sea levels are a constant threat to the city. Fusion’s Nicolas Ibarguen took a look into the stark future Miami faces as climate change takes root.”

Keeping Global Warming at 2C Rise May Not Be Enough, Says Climate Expert. Tech Times has the story; here’s a clip: “…Experts claim that the 2°C limit may still lead to shifts in rainfall patterns, the increase in sea levels and extreme natural events, such as heat waves, floods and droughts, especially in the tropics, high mountain areas and even the polar regions. Petra Tschakert, lead author of the IPCC Fifth Assessment Report, believes that the 2°C target may pose a threat to livelihoods and ecosystems…”
