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. Check the blog for more details. -Todd Nelson
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
Saturday starts off dry; temperatures more reminiscent of August. A few strong storms develop in western Minnesota later today along a cool front that will push across the rest of the state through the evening hours. Heavy downpours will be possible. Go figure. Check the blog for more details. -Todd Nelson
