August 24, 2006: Tornadoes and large hail strike southern Minnesota. One person died and 37 were injured when a strong tornado began 4 miles west-southwest of Nicollet in Nicollet County, and moved almost due east for 33 miles to near Waterville in Le Sueur County. Many storm chasers captured the tornado on video. The largest hail reported was grapefruit-sized at New Prague in Scott County.
August 24, 1934: Early cool air invades southern Minnesota. Rochester and Fairmont have lows of 34 degrees.
Clearing, Trending Cooler. Tropics Heating Up
I don't know much. Just ask my wife. But here is what I suspect: 1). Skies will clear today with a cooling trend into Friday morning. 2). Sunday looks like the nicer, drier day of the weekend. And 3). I will never (ever) own real estate along the Gulf Coast. Ever. Because I'd wind up spending way too much time watching The Weather Channel. Worrying about massive, Texas-size storms with names.

Life is too short.
The
ECMWF (European) model, which provided an 8-day heads-up with
Superstorm Sandy in 2012, is trying to bring a tropical storm (Hermine?)
into Florida by Sunday.
Gulf of Mexico water temperatures are unusually warm; high-octane fuel
for hurricane intensification, and this storm MAY strike the Gulf Coast Tuesday of next week. Let's hope it steers clear of Louisiana.
A wet start gives way to lukewarm sunshine today, with highs near 80F. A whiff of autumn Thursday leads to a slow weekend warming trend; a juicy warm front may spark numerous showers and T-storms Saturday. Sunday looks better - potentially lake-worthy.
The atmosphere is shifting gears as we limp into fall.

Tropical Briefing.
Aeris meteorologist Kristin Clark takes a look at the tropical wave
(99-L) that may intensify into a tropical storm or hurricane in the days
to come. NOAA's GFS model keeps killing the storm, but the ECMWF
(European model) pulls it into Florida as a tropical storm, with
possible strengthening in the Gulf of Mexico early next week. Check out
her report here.
Let's Hope This Doesn't Verify.
And I seriously doubt it will, but we should pay attention to all the
models, looking for trends. The European has been fairly consistent for 2
days now, pulling "Hermine" into southern Florida Sunday, then out over
the bathwater-warm waters of the Gulf of Mexico, where significant
intensification is possible. Models tend to do a much better job with
track than intensity, so take everything with a huge grain of salt until
we get within 48-72 hours of landfall. ECMWF solution valid next
Tuesday at 1am, courtesy of WSI Corporation.
Getting Better Organized?
As of late last night the convection circulation associated with 99-L
was becoming slightly more concentric, but it still has a long way to go
before reaching tropical storm strength. Conditions are favorable for
strengthening, especially as it (possibly) enters the Gulf of Mexico
early next week. Source: NOAA.
Spaghetti Plot.
Here are the various tropical model solutions for 99-L, keeping the
core of the storm north of Puerto Rico and Hispaniola. Confidence
levels are still low; people living along or near the Gulf Coast and
Florida should pay attention. I don't even want to imagine a scenario
where this storm pushes more heavy rain into Louisiana.
Tracking Aftershocks in Italy. Using the (free) Aeris Interactive tool you can track tremors, worldwide. Here is what we were looking at last night; a peak magnitude of 6.2 of the Richter Scale.
Taste of Autumn for Day 1 of the Minnesota State Fair.
Expect a stiff northwest breeze, a mix of clouds and sun and afternoon
highs in the low 70s. In the shade it may border on chilly (for some)
but most of us will find it refreshing. Temperature plot: Aeris
Enterprise.
Another Cool Correction - Mellowing Out Next Week.
I'm not yet convinced temperatures will hold in the 60s on Saturday
(possible if it rains long and hard enough) but Sunday should be the
drier, brighter, milder day of the weekend, with a good shot at low 80s
returning by the middle of next week. ECMWF forecast: WeatherBell.
Heat Lingers for Much of USA into Early September.
We should see fairly frequent cool frontal passages over the next 2
weeks; no sign of significant heat building close to home anytime soon.
That said, I doubt we've seen our last 90-degree day of 2016.
47th Anniversary of Hurricane Camille. WBRC.com in Birmingham has a good recap of this monstrous, Category 5 storm: "Wednesday marks
the 47th anniversary of Hurricane Camille making landfall along the
Mississippi Gulf Coast, devastating the coastline and the Pine Belt.
Camille made landfall as a Category 5 hurricane just after 11 p.m. in
Pass Christian with winds of 175 mph.
Other estimates placed the winds near 190 mph with gusts of 230 mph. The
exact speed will never be known since Camille destroyed all of the
weather sensors along the coast at landfall. Storm surge reached 24 feet
along the Mississippi Gulf Coast, which was the highest storm surge
ever recorded before Katrina. Camille is the second of only three storms
to ever make landfall as a Category 5 in the United States, the others
being the 1935 Labor Day hurricane in the Florida Keys, and Hurricane
Andrew in 1992..."

5 Reasons Some Were Unaware of One of the Biggest Weather Disasters Since Sandy. Dr. Marshall Shepherd explains at Forbes: "...The American public is somewhat conditioned to perceive a named or higher-category storm as more of a threat. The meteorological conditions that produced the Louisiana floods never received an official “name.” One NOAA Weather Prediction Center discussion actually referred to it as ”sheared inland tropical depression” or a monsoon depression. While this is meaningful to the meteorological crowd (maybe), this certainly is not going to resonate with the average citizen. Whatever it “was,” more rainfall fell in parts of Louisiana than some cities in California have seen in three to five years..." (File image: NOAA).
Why Obama Must Pay Attention to the Louisiana Floods. Here's an excerpt of an Op-Ed from Eric Holthaus at Newsweek: "...Words matter. And since Obama has staked a big part of his legacy on climate change, he owes it to the victims of the flooding in Louisiana, and the potential victims of future climate-related disasters, to address the clear and present threat of climate change directly in Louisiana. The President not only has the ability to improve the lives of the victims of this tragedy, by motivating attention and donations to help their plight, but to save countless future lives as well. To intentionally avoid this responsibility is unforgivable. To be a true leader, you have to change the status quo; when you're trying to lead on climate you have to change the status quo much faster than "normal" politics might say is possible..."

California Firefighters Stretched Thin As Blazes Sweep State. The Associated Press reports: "California's
state fire department is stretched thin just as the bone-dry state
enters the peak of its wildfire season, with vacancy rates exceeding 15
percent for some firefighters and supervisors. The vacancy rate is more
than 10 percent for some fire engine drivers, according to statistics
provided to The Associated Press. A five-year drought and changing
weather patterns have transformed what once was a largely summertime job
into an intense year-round firefight, said California Department of
Forestry and Fire Protection spokeswoman Janet Upton..."

America's First Offshore Wind Farm May Power Up a New Industry. Justin Gillis reports at The New York Times: "...By global standards, the Block Island Wind Farm
is a tiny project, just five turbines capable of powering about 17,000
homes. Yet many people are hoping its completion, with the final blade
bolted into place at the end of last week, will mark the start of a new
American industry, one that could eventually make a huge contribution to
reducing the nation’s climate-changing pollution. The idea of building
turbines offshore, where strong, steady wind could, in theory, generate
large amounts of power, has long been seen as a vital step toward a
future based on renewable energy. Yet even as European nations installed
thousands of the machines, American proposals ran into roadblocks,
including high costs, murky rules about the use of the seafloor, and
stiff opposition from people who did not want their ocean views marred
by machinery..."

11 Reasons To Be Excited About The Future of Technology. Medium has an uplifting, optimistic preview of what's to come: "In the year 1820, a person could expect to live less than 35 years, 94% of the global population lived in extreme poverty,
and less that 20% of the population was literate. Today, human life
expectancy is over 70 years, less that 10% of the global population
lives in extreme poverty, and over 80% of people
are literate. These improvements are due mainly to advances in
technology, beginning in the industrial age and continuing today in the
information age. There are many exciting new technologies that will
continue to transform the world and improve human welfare. Here are
eleven of them..."
