Meteorology is a Steep Learning Curve – Insane Precipitation Extremes Across USA Last 12 Months

A Reminder why today’s rain is welcomeBrian Brettschneider The Profound Perils of Predicting Weather You can only learn so much out of a book. Exhibit A: predicting the weather. Meteorologists study calculus, physics and chemistry, but at the end of the day we learn by making mistakes. Lot’s of mistakes. It’s a painful (and public) learning curve. The technology has improved (Doppler radar, better satellites and models) and as weather has trended more extreme over time fewer people are falling victim. We have new ways to receive warnings (smartphones and social media) and our National Weather Service is arguably the...

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...

Origin of “Dog Days” – Smoky US Summers On Increase Since 2016

Welcome to the Dog Days of Summer We get a whiff of Dog Days this week as daytime highs flirt with 90 degrees through Friday. Dog Days have nothing to do with an urge to pant or beg for treats, and everything to do with Sirius, the dog star – brightest in the nighttime sky. Ancient Greeks thought the star added to the heat of the sun, resulting in unbearable August heat. Of course it doesn’t quite work like that. Hazy, smoky sunshine lingers much of this week with thicker smoke the farther north and west you travel away from...

It’s Early To Be Tracking Smoke – Will “Drone Boats” Improve Hurricane Forecast Accuracy?

Paul Douglas Smoke, Heat & Drought? Welcome to Fresno! A friend living in Los Angeles told me that Californians don’t trust air they can’t see. I get it now. Remind me to never take a baby blue sky for granted again. Sadly, what happens in Ontario and Manitoba doesn’t stay in central Canada. Unusually dry weather is fanning an outbreak of blazes – drenching thunderstorms have been few and far between upwind, and that’s manifesting itself in a smoggy, smoky sky more typical of Beijing or New Delhi during the winter months. India with Lakes (and much better Scandinavian food)....

Using Cirrus Clouds to Predict Tornadoes – 156F Land Surface Temperature Last Week in US – Warming Climate Making Heat Waves Worse

NOAA Daunting Challenges in Meteorology Remain The forecast can always be more accurate. The words we choose to communicate weather can always provide more clarity. Story-telling 101. Two reasons meteorologists get fired up every day. That, and every day is different. Patterns may be similar, but never identical. Another challenge: there are 803 cities and smaller towns in Minnesota. All weather, like politics, is local. The forecast for Willmar is (slightly) different than Litchfield. Media outlets focus on major population centers, providing the macro view. Phone apps and web sites offer a micro forecast of localized weather for specific zip...

6 AerisWeather Features to Convert Mobile App Users to Paid Subscribers

In 2020 alone, mobile apps from the App Store and Google Play Store grossed more than $111 billion from in-app purchases according to SensorTower – a nearly three-fold increase from 2016. With so many great mobile apps launching every day in a hyper-competitive market, developers need to understand what options they have in providing value to app users to remain relevant in the marketplace. We’ve all thumbed through poorly-designed apps and been interrupted by ads that completely disrupt the user experience, it’s unpleasant and distracting when done incorrectly. As an alternate means of monetization, weather-influenced apps are rapidly shifting their model to...

“Medicane” in the Mediterranean Sea – “Teddy” and Likely “Wilfred” Threaten U.S.

2 Weeks Out – Cut Off Low Out East? Minnesota and the western two thirds of the USA are forecast to run milder than average, with a closed low causing clouds and showers (and cooler than normal temperatures) over much of the east. Praedictix Briefing: Issued Thursday morning, September 17th, 2020: Tropical Depression Sally Sally Weakening. While Sally has quickly weakened over the past 24 hours as the system continues to move inland, it is still producing heavy rain across portions of the Southeast this morning. As of 4 AM CDT, the center of Sally was 50 miles southeast of...

Wildfire Map and Air Quality Map Now Available

Changes in air quality can have wide-ranging effects for people, especially for children and sensitive groups, but also for everyone when air quality drops considerably. In May, we announced the addition of the Air Quality endpoints to the AerisWeather API.  Today, as we continue to expand our Air Quality API and datasets, we are announcing a new air quality map layer within the AerisWeather Mapping Platform (AMP).  The layer displays Air Quality Index (AQI) badges for locations globally and allows users to quickly visualize areas of concern.  Additionally, large wildfires can negatively affect local and regional air quality. Therefore, we are...
