Soggy Remains of “Ida” Threaten Mid Atlantic with Severe Flooding – Climate’s Role in Rapid Hurricane Intensification

GFS 2-Week Jet Stream Forecast No Rush Into Autumn. I still suspect September will wind up milder than average with more 80s, possibly another shot at 90 degrees – and with any luck showers and storms will become a bit more frequent in the weeks to come. Inland Flooding Potential from “Ida”NOAA and Praedictix August 29, 2021 file image of Hurricane IdaNOAA and AerisWeather In the History of Hurricane Names, “I” Stands for Infamous. They come at the midpoint of the hurricane season when ocean water temperatures are warmest, capable of fueling the most intense hurricanes. A little interesting trivia...

Louisiana Left Reeling from “Ida” – Hurricane Strength Was No Surprise to Forecasters – Mandatory Fire Evacuations in Tahoe Basin

Paul Douglas Why September May Offer Year’s Best Weather ”September tries its best to have us forget summer” wrote English philosopher Bernard Williams. I love all the seasons (and the fact that Minnesota HAS 4 seasons) but September is my favorite month of the year. Days are still lukewarm, lakes warm enough for one or two more dips. Severe storms are rare as the noisy blur of summer fades into comfortable days with cotton-ball cumulus and low humidity. That is all fine and good but Minnesota is still too dry and dusty. According to the local DNR “As of this...

Hurricane Henri Approaching the Northeast
August 26

Querying for Historical Tropical Cyclone Data with the AerisWeather API

As Hurricane Henri approached the Northeastern US this past weekend, I wondered how often a tropical cyclone has come within 50 miles of New York City, Boston, or other cities. How many were hurricanes? To answer these questions, we can use the Tropical Cyclones Archive endpoint within the AerisWeather API. This endpoint provides access to the complete AerisWeather historical archive for tropical systems, with data from the late 1800s for the Atlantic basin and the mid-1900s for the Pacific basin. When using the tropical cyclones archive endpoint, we find that 21 tropical cyclones have tracked within 50 miles of New York...

Flood Potential in the Middle of a Drought – USA’s Water Haves and Have-Nots?

Twin Cities National Weather Service A Risk of Flash Floods During a Drought ”Papa, tell me the story about the year we had floods during a drought?” Well Jordan, the year was 2021, and it was bone-dry. Parts of Minnesota were on fire. Farmer were worried, even the trees were stressed and losing their leaves early. And yes, we went from drought to flood in the meteorological blink of an eye. Strange? You bet. But I’ve seen rainbows after a tornado, rain the middle of a blizzard. Nothing surprises me much anymore. Excessive Rainfall/Flooding PotentialNOAA Nothing to See Here –...

NOAA Weather Radio: Cheapest Life Insurance Around – Anatomy of a Deadly Flash Flood in Tennessee

Cheap Life Insurance: NOAA Weather RadioPaul Douglas My NOAA Weather Radio Alarmed Me During the wee hours of Tuesday morning I was momentarily convinced we were under attack. Alarms blaring, a strobe light flashing in our bedroom. After unplugging the alarm clock it dawned on me that my NOAA Weather Radio was going off – for the first time in months. I’ve never been happier to see continuous lightning and hear rolling thunder, which sounded like artillery shells going off. 1-2 inches of rain soaked much of central and southern Minnesota and Wisconsin from a “meso-convective system”; a 200- mile-wide...

Deadly Flooding Legacy of “Henri” – Southwest USA’s Most Important River is Drying Up

At the end of the rainbow is a billboard?Paul Douglas Putting a Few Dents In Our Drought Mother Nature is extra-loopy this summer. Now that it’s late August the pattern looks like something I’d expect to see in early June: waves of warm fronts lapping north, each one accompanied by an outbreak of mostly nocturnal thunderstorms. There is a very good chance red blobs will freckle the Doppler today, again Friday, again Saturday night, followed by clearing on Sunday. I’m cautiously optimistic many thirsty lawns and fields will pick up 1-2 inches of rain today, but your results may vary....

Drought Deepens and Expands – Will Henri Strike New England for First Time in 30 Years?

US Drought Monitor Bringing Back Dusty Memories of 1988 Drought My 91 year old father (Volker) just flew in to meet his new great grandson (Jordan). He was immediately struck by the stress that trees, lawns and crops are experiencing from drought increasingly reminiscent of 1988. My father lives near Philadelphia, where they have been dodging floods and Kansas-size tornadoes. “With rainfall now it’s all or nothing” he observed. That is not far off the mark. The latest US Drought Monitor* shows severe to extreme drought in the metro, with a swath of exceptional drought over the Red River Valley....

Drought Intensifies – Water Shortages – “Grace” Threatens Cancun and “Henri” May Brush New England

All sharing options ECMWF Predicted Rainfall by Saturday Eveningweatherbell.com A Little Rain and Trickles of Canadian Air I’d rather track rainbows and unicorns on my Doppler, but there is something to be said for acknowledging reality. Whether it’s a virus or a rapidly changing climate, ignoring data and trends is often a precursor to pain. I’m a charter member of the common-sense, keep-your- eyes-wide-open party. Because you can’t fix what you can’t measure – or acknowledge. Since April 1 parts of Minnesota are the driest on record, according to the Minnesota State Climatology Office. It took us 5 months to...

Water Shortages Grow Across Southwestern USA – Top States for Wildfires – Natural Disasters Are…Political?

Precipitation Rank Since April 1 (1=driest on record)Minnesota DNR It’s Probably Best To Make No Assumptions The best assumption is to make no assumptions. This summer is proving to be an inflection point, a teachable moment on how climate flavors the weather.With water restrictions on the Colorado River many can’t assume water will come out when we turn the spigot. With conga lines of wildfires marching across the west throwing off massive smoke plumes we can’t assume skies will be blue and air will always be healthy to breathe. People take pictures of Lake Mead near Hoover Dam on Aug....

How to Display Individual Tropical Cyclones

The tropical season is upon us, with the seasonal peak just a few weeks away. As tropical storms and hurricanes form, our JavaScript SDK’s tropical module is perfect for displaying their track, latest position, and forecast. The Tropical Cyclone Demo displays many of the Tropical Module’s capabilities, showing users how AerisWeather can display tropical cyclones in real time. As we approach the seasonal peak in the Atlantic basin, there are often multiple active systems that may have overlapping tracks and five-day forecasts, such as this weekend, with Tropical Storm Fred and Tropical Storm Grace:   As seen, displaying tropical cyclones on a map can highlight overlapping...
