2021: Nearly as Many Billion Dollar Disasters as Record 2020 Season – Drought Spells Trouble for Hydropower – Can Grid Handle Renewable Revolution?

Maps Still Don’t Look Like Late October. NOAA’s GFS model roughly 2 weeks out shows a massive ridge of high pressure over the western US and much of western Canada, which suggests another warming trend by the third of fourth week of October. At this rate I wouldn’t be shocked to see a few more 70s within 2 weeks or so. World Meteorological Organization Sharpens Warnings About Both Too Much and Too Little Water. Inside Climate News reports: “The global supply of fresh water is dropping by almost half an inch annually, the World Meteorological Organization warned in a report...

Dangerous Air: Wildfire Smoke and Dangerous PM2.5 Increasing Plains to West Coast Since 2016

A magnificent meteorological mirage…Paul Douglas Exposure To Wildfire Smoke Is A Health Risk What happens in Vegas doesn’t stay in Vegas, and the recent swirl of western wildfire smoke didn’t stay in California. New research shows an average of 8-10 weeks of smoke every year in Minnesota between 2016 and 2020. This past summer was Exhibit A, both eye-opening and eye- watering. A few nearby towns experienced air quality worse than Beijing or New Delhi. Which has me thinking about masks and air filtration systems at home and in our vehicles. PM2.5 pollution is especially dangerous, responsible for over 4...

Ranking Severity of Southwestern Drought – Every Season Trending Shorter, Except for Summer

  You Might Want To Get Your Boat Out Soon I’m increasingly baffled by the definition of “nice weather”. A 3-day, 3-inch rainstorm would qualify as great weather news amid the worst drought since 1988. ”If you wait a few more weeks you may not be able to get your boat off the lift – and it may have to stay in all winter!” joked Dan Hause at Bayside Marina in Excelsior yesterday. On second thought, maybe he wasn’t joking water levels are down 2 feet on Lake Minnetonka, lower than any time since Hause started monitoring lake levels in...

Water Stress Increases Need for Reliable Weather Data to Power US Agriculture

“If there is magic on this planet, it is contained in water”, wrote Loren Eiseley. As a meteorologist, that quote has stuck with me over the years. But a warmer, more volatile climate is putting Earth’s hydrological cycle on fast-forward. The wets are trending wetter, the dries are drier. We are faced with too much water – or not nearly enough. The western US is enduring a 1200-year “Megadrought”, made worse by climate change. Cities are running out of water; fires and thick palls of smoke have become a daily fixture on local weather maps; all while a 7-8% increase...

Oklahoma New Lightning Capital of USA – Shifting Tornado Alley Impacting Insurance Rates – Will Improved GFS Model Catch Up With ECMWF?

ECMWF vs. GFS Accuracy Since 2007. The data is the data.Graphic courtesy of blog.weather.us and meteorologist Ryan Maue. Will a New GFS Model Upgrade Close the Gap with The European Model? Here’s an excerpt of an article I wrote for Aerisweather: “Are you with Team GFS or Team ECMWF, the “European Model”? I hate to pick sides, but as a meteorologist I defer to the weather model that, consistently, is most accurate. Of course I’m rooting for the “American Model”, the GFS or Global Forecast System, to win. But here’s the thing: if you’re sanding a table or building a...
