Above Average Fair Weather Lasts All Week

Today brings more sunshine, less wind and temperatures a few degrees milder; kissing 80F by mid-afternoon with low humidity. We'll heat up close to 90F again by Labor Day Weekend. "Idalia" may hit the Gulf Coast of Florida north of Tampa as a tropical storm or hurricane Wednesday. Check the blog for more details. -Todd Nelson

Tropical Depression TEN From Saturday

The National Hurricane Center starting issuing advisories for Tropical Depression TEN midday Saturday for a wave that was located just east of the Yucatan Peninsula. This storm will continue to lift northeast over the next few days and will likely intensify before making landfall along the Florida coastline as Tropical Storm or a Hurricane "Idalia" around midweek.

Heavy Rainfall Ahead

Regardless of how strong this storm gets, heavy rain will be one of the main concerns here. Widespread 3" to 6" or more will be possible from Florida through the Mid-Atlantic States, which could be problematic in terms of flooding.

Gusty Winds Expected

This system could potentially reach the Florida coastline as a Tropical Storm or a Hurricane with strong winds. There could be more issues along the Florida coastline as the storm intensifies and moves in midweek.

Atlantic Basin Climatology

Our recent uptick in the Atlantic tropical activity coincides with climatology, which suggests that things ramp up pretty quickly during the 2nd half of August and into September. This is when the sea surface temperatures are typically the warmest in the Atlantic Basin. Note that the actual peak of the season is on September 10th, which is less than 3 weeks away. With that being said, the next several weeks could be pretty active in the Tropics.

Minnesota State Fair Weather

"It's time once again for the "Great Minnesota Get Together." Weather plays quite a role in the State Fair experience. Who doesn't remember braving the heat with the crowds on one of the busier intersections on a sweltering afternoon? A quick rain burst will send people scurrying for cover, and folks savor balmy days in the 70s with just a bit of a breeze. Below are some State Fair weather facts and notable weather events that have happened in past Minnesota State Fairs. Quick History of the Minnesota State Fair The Minnesota State Fair has been held at its current site since 1885. Before that it was held at a variety of locations including Fort Snelling. There were some years when the Fair was not held because of war, disease, or for logistical reasons. These years are: 1861 (Civil War), 1862 (Civil and Indian War), 1893 (Columbian Exposition), 1945 (fuel shortage because of WWII), and 1946 (outbreak of Polio.) In 2020 the fair was not held due to COVID 19. Beginning in 1975, the fair has a 12-day run each year ending with Labor Day. Thus since 1975, the Fair begins on a Thursday in August. Before 1975, the Fair was held for shorter durations (eleven days from 1972 to 1974, ten days from 1939 to 1971, eight days from 1919 to 1938 and six days from 1885 to 1918). The 2023 Minnesota State Fair runs from August 24-Sepember 4."

Above Average Fair Weather Lasts All Week
By Paul Douglas

Yesterday I got my steps in at the Minnesota State Fair while clutching food with both greasy hands. Exercising with food - smart. Followed by a walk of shame to the newly renovated Ozempic booth, which was doing a brisk midday business. Maybe I dreamt that last part? Hmm. The weather felt like fall with clouds and a cool breeze; a non-issue for once.

Today brings more sunshine, less wind and temperatures a few degrees milder; kissing 80F by mid-afternoon with low humidity.

Here comes a quiet week with sunshine and 80s, a few degrees warmer than average. I still think we'll see a few 90s by Labor Day weekend, which sounds appropriate. The metro's 27 days at/above 90F will rise into the 30s by mid-September.

Hurricane season peaks in the coming weeks along with sea surface temperatures, and "Idalia" may hit the Gulf Coast of Florida north of Tampa as a tropical storm or hurricane Wednesday.

I'm heading back out to the fair today, and my wife will have me on a leash again. Hey wait, is that even legal?

Moon Phase for August 27th at Midnight

2.8 Days Until The Full "Blue" Moon

"Aug. 30 at 8:36 p.m. CDT - The second full moon occurring within a calendar month is usually bestowed this title. Although the name suggests that to have two Full Moons in a single month is a rather rare occurrence (happening "just once in a . . . "), it actually occurs once about every three years on average. There is actually a second and more arcane definition of a Blue Moon, apparently conceived by an almanac editor based in Maine back in the 1930s, but we will not get into this here. In addition, the moon will also be at perigee at 12:00 p.m. EDT., at a distance of 221,942 miles (357,181 km) from Earth. Very high tides can be expected from the coincidence of perigee with full moon (referred to as an astronomical spring tide). Finally, a full moon occurring very late in August or very early in September is sometimes bestowed with the title of Fruit Moon or Barley Moon. This will be the case with this second August full moon in 2023."

Climate Stories

(NOAA/The Minnesota Star Tribune)

"Years After the Blob, the Pacific Still Doesn't Look the Same"

"In late 2013, a mass of warm water now known as the Blob appeared in the northeast Pacific—a massive marine heatwave that cooked coastal ecosystems from Alaska to California. Later, bolstered by an El Niño, the vast and potent heatwave wreaked havoc on marine ecosystems: thousands of seabirds died, while blooms of harmful algae poisoned marine mammals and shellfish. The suddenly warmed water also brought an influx of new animals to the northeast Pacific: ocean sunfish appeared in Alaska, while yellow-bellied sea snakes popped up in Southern California. By 2017, the Blob had waned and many of these more tropical species had retreated. Yet not all. Some of the species that colonized new habitats during the heatwave have stuck around. And now, says Joshua Smith, a marine ecologist at the Monterey Bay Aquarium in California who documented in new research how the Blob triggered a range of subtle yet persistent shifts in the spread of marine species, "I'm starting to sort of question whether those communities will ever look the way they did."

"Climate change is coming for your olive oil, too"

"Inflation is finally easing. Americans are paying less for gas than they were a year ago. Furniture, television, and airfare prices have all fallen since last summer. Even the used car market is cooling off after its meteoric rise. But one unsuspecting staple in many American kitchens has become a prominent outlier: olive oil. The price of the already pricey liquid fat has soared to a record high this summer. It's the latest chapter in the annals of heatflation — when scorching temperatures harm crops and push food prices up. A yearlong drought and a spring of extreme heat in Spain, the world's largest olive oil producer, devastated the country's olive groves. Spanish olive oil production fell by a half — from an estimated 1.3 million to 610,000 metric tons — over the past year. Now fears are mounting over the very real possibility that the country's inventory will run out before the next harvest begins, in October."

"It's So Hot, Congress May Actually Pass a Law About It"

"What are we going to do about the heat? As devastatingly hot as this summer has been — and it has broken records and likely killed thousands of Americans — next summer will almost certainly be worse. Will Congress act? New federal legislation to attack the root of the problem by reducing carbon emissions isn't on the table, thanks to Republican control of the House. But that doesn't mean there's zero chance of any kind of heat legislation emerging this year. Republicans have proven open to funding ideas like better hurricane forecasting, the streamlining of flood insurance claims, and more seawalls — all things that get lumped into the category of adaptation to extreme weather or resilience. Could something similar be possible for heat? A handful of bills have been introduced — almost all by Democrats — that seek to adapt to heat in one way or another. Because adapting to hotter temperatures isn't as simple as erecting new levies, all the legislation seeks in one way or another to ensure everyone has access to a cooler environment. That might mean giving people money to keep their air conditioners running, funding cooling centers, or building shade outside."
