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...

Ripening Fall Colors – Using Satellite Wind Lidar to Improve Hurricane Forecasts – Summer Wildfire Smoke Emitted More CO2 Than India Does In a Year

Fall Color FinderMinnesota DNR Falls Colors Peaking Over Minnesota Arrowhead The outlook for the next few weeks calls for a blizzard of color, caravans of determined leaf-peepers, and backyard workouts involving rakes. The leaves are leaving, but not before a crescendo of color, nature’s exclamation point, coming at the end of the hottest summer on record for Minnesota and the nation. Colors are peaking over the Minnesota Arrowhead, but the most vibrant hues of magenta, rust and lemon may be 2 weeks away in the metro area. Trees are stressed from the ongoing drought, so colors may be more muted...

30% of USA Impacted by Extreme Heat – Timeline of Most Disruptive Weather – Odds Favor Milder Than Average Autumn for Much of Nation

File image near Pequot LakesPete Schenck So Why Do We Call This Season “Fall”? Today at 2:21 pm the sun’s direct rays will fall on the equator, marking the official start of autumn. Which is all fine and well, but if you look at the 90 warmest days of the year, on average, “Meteorological Fall” really started back on September 1. The term “fall” may be a contraction of Middle English expressions like “fall of the leaf” or “fall of the year”. And if anyone asks, sex drives apparently peak in the fall. More people go from “single” to “in...

Consensus of Climate Models Predicts Mild Bias Into December

  A Handful of Cooler Fronts In Sight – Mild Bias into December? The only predictable thing is change. our weather patterns are changing, with longer growing seasons and fickle winters with brief, concentrated polar blasts. Wets are wetter and dries are trending drier. I am cautiously optimistic the pattern that brought us a hot and dusty summer is finally easing. But pulling out of the drought will take months, not weeks or days. Think dimmer switch, not on-off. NOAA’s climate models show a mild bias lingering into December, and I have every reason to believe Minnesotans will enjoy a...

NOAA Climate Models Predict Milder Autumn – Tracking Fall Warming Trends Over the Years

Septembers Tend To Be Quiet in Minnesota Ah, September. The biggest weather-related questions are: 1). When will we check out a kaleidoscope of dazzling fall color? and 2). Shorts or jackets? June brides should consider the month of September, when Mother Nature is (usually) on her best behavior. This summer we all got a front row seat to the New Normal: wilting drought, fire and smoke from Minnesota westward to the Pacific. Tornadoes in unlikely places (New Jersey) and epic floods from the Gulf Coast to the East Coast. I’m hoping we all get a nice, long break before frozen...

Category 3 “Larry” Brushes Bermuda – Most Climate-Safe US State?

Paul Douglas Minnesota May Benefit From Slow Warming A recent study suggests that Vermont is the most “climate-safe” state in the US. That may be so, but I suspect Minnesota will get its fair share of climate refugees in years to come. How so? Californians worried about wildfires and months of choking smoke. Arizonans concerned about hotter hots and water shortages. Residents of the Gulf Coast unable or unwilling to put up with a parade of increasingly intense and wet hurricanes. Minnesotans will still wrestle with snow, ice and polar pops, but in the Pantheon of Weather Extremes slapping on...

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...

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.

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...

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....
