According to the MN DNR, the fall color season is underway and happening fast. Parts of western and northwestern Minnesota are halfway through the season with peak not far behind. Fall colors will continue to rapidly change, so take a moment and enjoy the season while you can. Note that most leaves will vacate the premises in about 1 month and won't return until sometime in mid/late May...

Ophelia on Saturday

Tropical Storm Ophelia developed in the Atlantic on Friday and becomes the 11th named storm of the 2023 Atlantic Hurricane Season. Here's some information from Phil Klotzbach on Twitter: "Tropical Storm #Ophelia has formed off of the North Carolina coast - the 11th Atlantic named storm to form since August 20. The only season with more Atlantic named storm formations between August 20 - September 22 is 2020 (12 formations). #hurricane"

Tropical Storm Ophelia

According to NOAA's NHC - Ophelia makes landfall along the North Carolina coast early Saturday morning and will drift north through the Mid-Atlantic states through the weekend and early next week. Tropical Storm Warnings have been posted for the likelihood of strong winds, storm surge and very heavy rainfall. There could even been some isolated tornadoes and Ophelia moves inland.

Past Peak of the Atlantic Hurricane Season

The Atlantic hurricane season runs from June 1st to November 30th, but did you know that the typical peak is September 10th? This is when the Atlantic Basin has had the most hurricanes and named storms since records began. This is also when weather conditions are at optimal levels for these types of storms.

Showery Rain Lingers Into Monday Night
By Paul Douglas

Well that was fun. "We interrupt this drought for downpours, severe storms and a possible tornado - on the first day of fall". Makes perfect sense to me. Welcome to an all-or-nothing weather world. Is your preference droughts or floods?

According to Dr. Mark Seeley, parts of Minnesota are running a 7-12" rainfall deficit for 2023. Over 64% of Minnesota is in severe drought or worse, and the USDA rates 20% of the state's corn and soybean crop in poor or very poor condition. This rain certainly helps, and some 1-2" amounts are possible for a few lucky towns before showers finally taper early Tuesday. It'll put a dent in the drought, but it's not the soaking we need.

A dry sky is expected Wednesday into the weekend (T-storms over far northern Minnesota) with another warm front. Are you interested in a deal on warm fronts? You may be in luck. Models show 80s the first few days of October. Wut?

A brewing Super El Nino may spark 70s deep into October and a late start to winter across Minnesota. Follow the trends.

Climate Stories

(NOAA/The Minnesota Star Tribune)

"RATE OF CLIMATE-INDUCED EXTINCTION IS 'SHOCKING'"

"Researchers surveyed populations of the Yarrow's spiny lizard in 18 mountain ranges in southeastern Arizona and analyzed the rate of climate-related extinction over time. "The magnitude of extinction we found over the past seven years was similar to that seen in other studies that spanned almost 70 years," says John J. Wiens, a professor in the ecology and evolutionary biology department at the University of Arizona and senior author of the study in Ecology Letters. The Yarrow's spiny lizard native to the southwestern US and western Mexico can be spotted in oak and pine forests in 18 of Arizona's Sky Islands mountain ranges. Wiens and his group did initial surveys of the Yarrow's spiny lizard in these mountain ranges in 2014 and 2015. In 2021 and 2022, Wiens, along with Kim Holzmann, his former master's student and the new study's lead author, and Ramona Walls, a part-time researcher at the University of Arizona's BIO5 institute, resurveyed to investigate if there had been any changes in the lizard populations since then."

"Wildfire risk is soaring for low-income, elderly and other vulnerable populations in California, Washington and Oregon"

"As wildfires burn across the Western U.S., the people in harm's way are increasingly those least able to protect their homes from fire risks, evacuate safely or recover after a fire. In a new study, we and a team of fellow wildfire scientists examined who lived within the perimeters of wildfires over the past two decades in Washington, Oregon and California – home to about 90% of Americans in the U.S. West exposed to wildfires over that period. Overall, nearly half a million people in California, Oregon and Washington were exposed to wildfires at some point during the past 22 years. Alarmingly, about half the people exposed to wildfires in Washington and Oregon were considered socially vulnerable. While the number of people exposed to fire rose overall, the number of socially vulnerable people exposed more than tripled between the first and second decades."

"Australian Officials Declare the Arrival of El Niño During Blistering Heat Wave"

"Australian authorities declared the arrival of El Niño, amid dangerous heat waves that are raising the country's risk of widespread bushfires. The Australian Government's Bureau of Meteorology (BoM) announced the arrival of El Niño in an outlook after seeing a combination of conditions that include higher-than-average ocean temperatures. "Climate model outlooks suggest this El Niño is likely to continue until at least the end of the southern hemisphere summer 2023–24," the announcement said. El Niño is the warmer phase of a natural planetary cycle. It's associated with a band of warm ocean water that develops every few years off the equatorial Pacific, and that warm water can shift global weather patterns. Officials held off on declaring the global shift as it experienced several years of heavy rain and devastating floods. And now the country can expect especially hot and dry conditions. During El Niño, Australia also sees lower rainfall."
