"Like a 20 Minute Hurricane": 70+ mph straight-line winds hit metro (ripe for more flash flooding and severe storms into the weekend)
June 21, 2013 — 9:14pm
Ripe For More Flash Flooding. I'm increasingly concerned about a train-echo effect, a conga-line of thunderstorms forming along an east-west warm frontal boundary over southern Minnesota. More clusters of strong to severe storms are moving into the metro, a pattern which may be repeated much of the night. If this keeps up we could be faced with very serious flooding by Saturday morning. Stay alert, and if you live in a flood-prone area be ready to move. NWS Doppler at 9:13 pm.
Multi-Million Dollar Storm? That's a WAG on my part, but based on some of the photos I'm seeing, and the scope of the straight-line winds that blew thru, I suspect damage will run into the (many) millions of dollars from today's rain and wind. There's no evidence of tornadic winds, but straight-line winds were strong enough (60-80 mph) to bring down big trees. Photo from South Minneapolis (upper right) courtesy of Dominic Hanzely.

Big Trees Down. Walt Kruhoeffer sent in this photo from Uptown, the scene right outside his apartment window - big trees down, still no power.
Serious Flash Flooding These are Doppler radar estimates of rainfall amounts from the severe cell that pushed across the metro area between 6:30 and 8 pm, whipping up 70 mph (straight-line) winds. Ground already saturated from early morning storms made it easier for trees to topple over, and there are numerous reports of trees down across the metro area from this severe storm. NO EVIDENCE OF A METRO TORNADO. I suspect these were almost entirely straight-line winds from a small, compact, derecho-like severe storm.
Stay Home. If you don't have to travel this evening stay put. If power is out, chances are you're not reading this, but I'm worried about people stepping on downed power lines. I drove into this mess after appearing on TPT Almanac. It was like driving into a 15 minute hurricane, total white-out, like being in a warm weather blizzard, waves of wind buffeting vehicles, many drivers parked under bridges on I-394. I saw numerous (big) trees down, many roads blocked, too many power outages to count and street lights out. What a mess.
Ripe. With a vigorous warm frontal boundary draped over southern Minnesota we may see a "train echo effect" overnight. Much like the cars of a train passing over the same section of track, strong to severe thunderstorms may keep redeveloping over the same counties, each one squeezing out 1-2" rain. The result may be serious flooding, and a Flash Flood Watch remains in effect for much of Minnesota into Saturday. Take the flood risk seriously.
Flash Flood. Lee Huffman sent me this photo from the Loring Park, Minneapolis area this evening, about 2-3 feet of water overwhelming vehicles and people just trying to wade thru the instant-flood.
Incredible Rains. 2.2" of rain in 30 minutes in Maple Plain. That's 2 week's worth. It shows you how much water is floating overhead. Any rain from additional storms will immediately run off into streets, streams and basements. If you often experience spring flooding you may have a long weekend ahead of you.

Wednesday sure looked and felt like autumn under a gray sky with a cool breeze. We stand a better chance of spying the sun today with temperatures mellowing close to 70F by tomorrow. No more heat waves - and a welcome lack of downpours into Tuesday of next week. Meanwhile we're keeping an eye on "Matthew" in the Caribbean. Will this be our October surprise? Too early to say.
The big story is news that we had not one, but two mega-rain events this past summer, based on forensic data and investigation by the Minnesota Climate Office and DNR. These sprawling areas of flooding appear to be on the increase; we've experienced at least 7 of these events since 2000. Somehow we get a break in the puddle treadmill with cool sunshine the rule from today into the weekend. Good timing for the Ryder Cup. Have you heard it's in town town? I had no idea. I'm just gratified we were able to squeeze in a big, glitzy, high-visibility international event - in between floods.
A large area of low pressure centered over Ontario is responsible for this windy nonsense. While wind gusts won't be quite as strong as they were Monday, we'll still have a nagging breeze to combat as you meander about outdoors. The low clouds surrounding the storm system will also make an appearance again Tuesday with passing showers that will likely be present during the afternoon hours.

As the stubborn storm drifts east, a ridge of high pressure builds in allowing sunshine and dry weather to persist for several days. Golfers and golf fans will be appreciative of the downpour free forecast as the Ryder Cup comes to town this week. Check the blog for more updates. -Todd Nelson
An Octoberish wind develops over the next few days with high temps dipping into the 50s and 60s across the state. Clouds and a few spits of rain linger through Monday; Great Ryder Cup weather settles in Thursday. Dry and sunny! Check the blog for more details. -Todd Nelson
