I'm thoroughly enjoying the Mosquito Olympics, now playing out in my buggy backyard (available on ESPN7). If the rains keep up I'm going to need a low-flying helicopter to cut my lawn.
Welcome to monsoon season in Minnesota. Rainfall for the last 30 days is already 3-8 inches above average for portions of central Minnesota, and the rains just keep on coming. Once again, for the umpteenth time in recent memory, weather systems are stalling, and when weather gets stuck you need to pay close attention.
A stalled frontal boundary snaking across Minnesota will ignite more heavy T-storms again today; heaviest rains on the cooler north/west side of the front - but the MSP metro may see tropical downpours capable of 1-2 inches, enough for standing water and garage-worthy grad parties.
Have a Plan B and hope for the best.
A ripple of low pressure keeps gulley-washers in the forecast into Monday but Wednesday's storm may steer showers and storms south of the metro. We slowly warm late next week with spotty weekend T-storms. Right on cue.
I'm still betting on a wetter than average summer, statewide, but El Nino may keep us warmer and drier the latter half of 2014.
Keep the faith.

Global Warming and the Vulnerability of Greenland's Ice Sheet. Climate models have consistently underestimated the rate of ice melt in Greenland (and the Arctic). Here's an excerpt of a story at The Guardian: "...This work is important because in the past decade or so, it has been found that Greenland is losing ice, lots of ice, to the world’s oceans. As a consequence, Greenland is one of the significant contributors to sea level rise. The level our oceans will rise to in the next decades and centuries depends strongly on how fast the Greenland ice sheet will melt. This study is novel because of the way it combined measurements with mass-conservation calculations. The method allowed far better resolution of the thickness of Greenland glaciers and the shape of the valleys beneath the glaciers. The shape and depth of these valleys is important for moderating the speed of ice flow to the oceans. In fact, in the paper, authors state, “the overall state of mass balance of the ice sheet is affected by considerable uncertainties in bed topography and ice thickness...”
