Meteorologists face two daunting challenges: predicting the weather and communicating those changes to the public. The forecast is rarely black or white - usually some nebulous shade of gray. The words we choose for the 7-Day Outlook help to communicate the extent and persistence of precipitation. "Rain" implies everyone gets wet, with puddles most of the day, while a "shower" suggests a 30-60 minute window of wetness.
"Partly sunny" means the same thing as "mostly cloudy"; a day with more clouds than sun. Meteorologists provide the big picture; smartphone apps pinpoint weather for your GPS location. The best forecasts are still man and machine working together.
A surge of steamy air ignites waves of T-storms today into Thursday night. 2-4 inches of rain falling on saturated soil up north may spark more flash flooding for central Minnesota and the Brainerd Lakes.
Humidity drops off on Friday with northwest winds blowing behind a cooler front. The weekend looks comfortable with 70s and a few pop-up showers each afternoon.
In the meantime, welcome to the jungles of Minnesota: steamy with tropical downpours.

Warmer Than Average July, Year To Date Third Warmest For Lower 48 States. Details via NOAA: "July’s reputation for sizzle didn’t disappoint, bringing record warm temperatures to Florida and New Mexico and much above-average temperatures across the South, the East Coast and Alaska. The average July temperature for the contiguous U.S. was 75.3 degrees F, making it the 14th warmest July on record, according to scientists from NOAA’s National Centers for Environmental Information. July precipitation averaged 2.87 inches (0.40 inch above average). From January through July, the average temperature for the Lower 48 states ranked as the third warmest on record at 54.3 degrees F, 3.0 degrees above average. Thirty-eight states were much warmer than average..."

This Is Where The First U.S. Offshore Wind Turbines Were Just Installed. Fortune has the story: "The first wind turbines to be installed off the coasts of the United States were constructed over the past few days about three miles offshore of Block Island, Rhode Island. While wind farms have been built all over the U.S. on land, the market for building wind farms in U.S. waters has stalled thanks to legal threats, lack of regulatory support, and push back from coastal property owners. At the same time, the “offshore wind” industry has boomed throughout Europe..."

NASA Has Some Wild Ideas For The Future of Flying. Grist explains: "NASA recently announced that it will start studying a bunch of cutting-edge aviation ideas — four of which could make commercial air travel much cleaner than it is today. The announcement comes after the EPA said that it’s going to crack down on airplanes’ greenhouse gas pollution. Think of NASA’s schemes as a window into what a cleaner future will look like.
- First up, fuel cells. They’ve been used in spaceflight programs since the 1960s, but they’re still too complicated to work elsewhere. NASA wants to develop more efficient fuel cells and use them to replace the standard piston engines found in most aircraft..."

Science Communication as a Moral Imperative. Dr. Jonathan Foley, Executive Director of the California Academy of Sciences has an Op-Ed at the MACROSCOPE; here's a clip: "...To all of these scientists and academic administrators, I say this: you are failing one of the most important moral imperatives of science in the 21st century. As scientists, we owe it to the world to do a better job communicating the wonders of science, and the incredible discoveries being made by our field, to everyone around us. And in this moment of history, when addressing scientific issues has never been more urgent and important, we have a special duty to share our knowledge, expertise, and passion with the wider world. It is part of our social compact as scientists..."
