Lessons Learned From The June 21 Mega-Storm. Last Friday evening's bow echo, severe winds and flooding rains were a subtle (yet blunt) reminder that damage from severe thunderstorms can be even more extensive than a tornado touch-down. The latest edition of Climate Matters is here: "It wasn't a tornado, but hurricane force winds combined with a saturated ground that led to widespread damage and the largest power outage in Minnesota's history. Friday night's storm was the equivalent of a 15-mile-wide EF-0 tornado, and WeatherNation Chief Meteorologist Paul Douglas says it serves as a reminder that you need to take severe thunderstorms seriously."
Bow Echo. Click to activate loop. Here is a loop (GR2) of the severe thunderstorm that swept across the metro area Friday evening, becoming more severe as it pushed east of Lake Minnetonka toward South Minneapolis, whipping up a 70-80 mph gust front in the process.
Thundery Holding Pattern. Once again weather systems are creeping eastward across the USA, showers and T-storms, some strong to severe, will continue to flare up from the Midwest into the Great Lakes and New England. The southwest remains dry - nothing brewing in the tropics thru the 4th of July.
3 Dry Days In A Row? Don't get your hopes up too high. Our track record isn't very promising as of late, when storms and fronts seem to be spaced about 24 hours apart. Showers and T-storms linger into Wednesday, but ECMWF data (and other models) confirm a mostly-dry spell from Thursday into Saturday; probably the nicer, drier day of the weekend. A few showers are possible Sunday, temperatures on the cool side of average into the 4th of July holiday weekend. No big heat spikes for the 4th? Tell me you're really surprised.
1. Power plant clampdown
All eyes are on EPA, the federal agency in charge of writing and implementing what are likely to be some of the most controversial regulations in the president’s second term: limiting carbon emissions from both new and existing power plants. Heather Zichal, the White House energy adviser, suggested Wednesday that EPA is committed to moving forward with climate regulations for power plants, particularly from the fleet of coal-fired plants that have traditionally provided the bulk of the country’s electricity. Power plants are the biggest source of U.S. carbon emissions..."
Albertans have also learned that climate change delivers two extremes: more water when you don’t need it, and not enough water when you do. The geographically challenged have also become learned, once again, that water travels down hill and even inundates flood plains.
So climate change is not a mirage. Nor is it weird science or tomorrow’s news. It is now part of the flow of daily life."Photo credit: "This undated photo provided by the Calgary Flames shows the inside of the Calgary Saddledome in Calgary, Alberta. The Saddledome, home to the National Hockey League's Calgary Flames, was flooded up to the 10th row, leaving the dressing rooms submerged. The two rivers that converge on the western Canadian city of Calgary are receding Saturday, June 22, 2013 after floods devastated much of southern Alberta province, causing at least three deaths and forcing thousands to evacuate."
