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....

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...

Tracking “Fred” – Racial Realities of Urban Heat Island – Key Takeaways of Latest UN IPCC Climate Report

Scientists React To Latest IPCC Report Every IPCC climate report becomes a little more dire with time as scientists draw a straight line from a doubling of planet-warming greenhouse gases since 1850 to an increase in weather extremes. During a WCCO Radio interview Tuesday, St. Thomas climate scientist John Abraham reacted to the report. “It’s unequivocal, humans are causing the warming. We are now seeing the impact on our weather. It is too late to avoid climate change, but what we’re trying to do now is avoid the worst of climate change” he said. The uptick in weather disasters is...

Drought Intensifies Western Third of USA – Some Improvement Intermountain West

Driest Meteorological Summer, To Date, Since 1982 I’m enjoying my time here in Bakersfield, California, between the heat, drought, smoke and occasional wildfires”. [checks notes]. Wait, I recall living in Minnesota, which has a vast constellation of lakes. Water shouldn’t be an issue, right? Wrong. Dr. Kenneth Blumenfeld, Sr. Climatologist at the Minnesota DNR, informs me that since June 1 the metro area experienced the driest weather since 1982; the 5th driest since 1871. Short-term moisture deficits are very significant, he confirmed. It’s very hard to dig out of a drought, especially during summer months, when precipitation is spotty, hit-or-miss,...

NOAA NHC Predicts Above Average 2021 Hurricane Season – Populations Booming in Flood-Prone Areas of the World

Topsoil MoistureUSDA More Dog Days To Come. Although Minnesota won’t be as (smoking) hot as the central Plains, I see a fairly steady run of 80s and a few 90s into the third week of August. Then again the Minnesota State Fair is coming, which is good for a few more 90s, right? The canals that used to bring water to the fields of Caywood Farms have gone dry due to the drought.

Nuisance Flooding Set to Increase – Tiny Satellites May Revolutionize Hurricane Forecasting – A Summer of Pyrocumulonimbus

File: July 15, 2021NASA Earth Observatory A Summer of Fire-Breathing Smoke Storms. NASA’s Earth Observatory explains the difference between cumulonimbus and pyrocumulonimbus: “In 2000, atmospheric scientists from the U.S. Naval Research Laboratory (NRL) first reported that smoke plumes from intense wildfires could spawn towering thunderstorms that channeled smoke as high or higher than the cruising altitude of jets. These pyrocumulonimbus, or pyroCb, events wowed scientists at the time. Prior to that discovery, only explosive volcanic eruptions and extreme thunderstorms were thought to be capable of lofting material so high. Though the workings of these smoke-infused storm clouds have come into...

Uptick in Flooding is Extreme, Global, and Linked to Continued Warming

Image credit: United Nations Climate Change Twitter Feed. All weather, like politics, is local. Increasingly, climate change hits home when it…hits home. Muddy, waist-deep water in your living room has a way of focusing one’s attention. The symptoms of a warmer, wetter world are hitting home with greater frequency and ferocity, becoming more apparent over time – harder to dismiss and deny. On July 29, 2021, the Chinese city of Zhengzhou (population 12 million) received a staggering 8” of rain in one hour. 24” of rain fell in one day – a year’s worth of rainfall.   Historic flooding in...
