50 F. record low for Sunday, July 28, set in 1981. We will come close.
15 F. temperatures will average 15 F. cooler than normal today.
Sunday still looks like the nicer, sunnier, milder day of the weekend.
72 F. high in the Twin Cities Friday.

July Wind Chill (doing a calendar double-take)
Here's a horrific bit of weather trivia: July is
the only month where snow hasn't been reported at an official Minnesota
reporting station. The city elders don't like to share that fun nugget.
Roger Kormendy from Prior Lake writes "So for a
few days our weather is being influenced by “Canadian Air” as
meteorologists around here and probably across the country refer to. My
question is, do Canadian meteorologists refer to air invading from the
south as “American Air”? Great question. We could use some lukewarm
American Air right now.
Forget about glancing blows of fresh air. We're
talking CANADIAN OCCUPATION here; a "cut-off" low - a swirl of unusually
chilly air breaking off from the main belt of westerlies. Typical for
October, but late July? Not so much. I'm predicting a few 30s tonight up
in Tower & Embarrass, the Twin Towns of Cold.
After a brisk, bracing, invigorating start
(buying any of this weather-spin?) clouds build this afternoon. A stiff
wind means only the brave & foolish will be in the water. Sunday
looks sunnier; a notch milder. You'll only need 2 T-shirts instead of 4.
Deep breaths.
80s return the latter half of next week - but not a 90 in sight.
30s Sunday Morning Minnesota Arrowhead.
If skies clear and winds ease a bit temperatures will drop into the 30s
over Minnesota's Arrowhead late tonight, maybe mid-30s Embarrass and
Tower. Map above: NOAA.
Warming Trend Next Week. No
worries - think of this as a mid-summer intermission from heat and
humidity. Although no searing heat is brewing anytime soon we will see a
rerun of 80s by the middle of next week. The best chance of showers and
T-storms: Tuesday, again Friday of next week.
Short-Term Chill; Longer-Term Warm Bias? In spite of
the chill outside your window today some of the longer range models are
showing a warm bias for autumn, continuing the recent trend of
(milder) falls across Minnesota and the Upper Midwest. In today's
edition of
Climate Matters
we update Dorian, Flossie (which sounds like a bunny rabbit), and the
implications of a buckling of the jet stream into a very strange, almost
unheard-of July "cut-off" low.
Obama Signs Disaster Declaration For Counties Hit By Solstice Storm.
City Pages has the details; here's an excerpt: "
Last
week, both members of congress -- along with Gov. Mark Dayton, Sens.
Amy Klobuchar and Al Franken, and four other U.S. reps -- asked President Barack Obama
to issue a disaster declaration for the 18 counties in Minnesota
hardest-hit by the solstice storms. Yesterday, he did. The presidential
signature means that now, the feds can step in with more funds to help
clean-up and rebuild infrastructure and public property. Preliminary
assessments peg the tab for recovery at $17.8 million, a good $10
million higher than initial estimates..."

Unusual Tornado On July 22. I thought this was especially interesting, an excerpt of Dr. Mark Seeley's always-excellent
WeatherTalk Newsletter: "
The
NOAA-National Weather Service Grand Forks Office reported on an
unusual tornado earlier this week that struck between Mahnomen and
Zerkel (Mahnomen County). This storm was unusual in several aspects:
firstly it struck between 1:50 AM and 2:30 AM on July 22nd (Monday), a
very rare time of day for tornadoes in our region (less than 2 percent
of all tornadoes occur at that time of day); second, wind speeds were
estimated to range from 110-120 mph (EF-2 strength), unusually strong
for an overnight storm; thirdly, the storm path was nearly 18 miles in
length (though intermittently on the ground), a relatively long storm
path for an overnight storm. Thankfully this tornado did not cause any
deaths or injuries, but it did damage a home, a number of farm
structures, along with some farm equipment. It also caused a good deal
of tree damage, especially around Roy Lake. This was the 6th confirmed
tornado of the year so far in Minnesota. You can read more about the
2013 tornado season in Minnesota at the MN State Climatology Office web
site.....

It's 90 Degrees In Siberia And People Are Sunbathing. Even more incredible, there's a publication called the "Siberian Times". Who knew?
The Atlantic Wire has more details
:
"Your mental image of Siberia is probably a snowy, wind-whipped
expanse, perhaps with a cluster of buildings to house those banished
from Russian society. Not this week. This week, Norilsk, the
northernmost large city in the world, the second largest city north of
the Arctic Circle, and the site of one of those gulags, hit a balmy 32
degrees Celsius — about 90 Fahrenheit. It's normally in the mid-60s. The
online outlet The Siberian Times ("up-to-date information in English
from across Siberia's six time zones") featured a photo of people
sunbathing on the shores of Lake Baikal in its report on what may be a new record high..."
Here's what we're monitoring:
* Tropical Storm Dorian
has weakened over the last 24 hours, packing 50 mph sustained winds.
It's running into drier air with increasing wind shear, preventing the
storm from strengthening to hurricane status for at least the next 4-5
days as it pushes toward Cuba.
* Tropical Storm Flossie
expected to weaken into a tropical depression before drifting over
Hawaii; capable of torrential rains and significant flooding by Tuesday
of next week.
Dorian: An Unimpressive Tropical Storm.
A combination of dry air becoming entrained in its circulation and
increasing wind shear is causing Dorian to weaken, a trend which is
expected to continue into the weekend, in fact Dorian may lose tropical
storm strength. That doesn't mean we can discount the storm altogether.
Wind shear is forecast to weaken slightly as it approaches the
Caribbean, and with the storm moving into an area of warmer sea surface
temperatures some strengthening is still possible next week.
Latest Numbers.
T.S. Dorian is moving briskly toward the west-northewst, on a track
which should still take the storm north of St. Martin, The U.S. Virgin
Islands and Puerto Rico by Sunday. Heavy rain squalls are possible from
St. John to San Juan, but the core of the storm should stay 50-150 miles
north of the islands. More serious flooding is possible Monday and
Tuesday as the storm brushes Haiti and the Dominican Republic.
Short-Term Track: High Confidence.
The models are (amazingly) aligned, showing the track of Dorian over
the next 5 days, posing the greatest risk to the southern Bahamas and
Cuba in a Monday-Tuesday time frame next week.
Long-Term Track: Low Confidence.
After pushing near Cuba by Monday or Tuesday, the models are
(literally) all over the map with where Dorian may go next. An
increasing number of solutions take Dorian into the Gulf of Mexico,
which would probably be the most threatening solution for the U.S. Water
temperatures are unusually warm in the Gulf, and Dorian might
strengthen significantly if it takes a more southerly rouute. Just as
many models veer the storm to the north, possibly soaking Florida with
heavy rains the middle or end of next week before pushing out into the
Atlantic. Confidence levels are still very low regarding the long-term
path of Dorian, and even whether this storm poses a significant risk to
facilities in the U.S.
Sputtering Along.
The combination of dry air and wind shear will probably conspire to
keep Dorian a modest tropical storm, at least looking out 120 hours. A
few of the models even weaken Dorian to a tropical depression or
tropical wave beyond 60 hours, a scenario which is very believable
looking at the data.
Timing Dorian.
Based on guidance from NOAA NHC Monday looks like the wettest day for
Puerto Rico; minor flooding can't be ruled out, but right now this does
not look like a significant/deadly storm scenario. More serious flooding
is possible from The Domincan Republic to Cuba and the Bahamas by
Tuesday and Wednesday of next week.
A Hawaiian Soaking.
Tropical Storm Flossie is expected to weaken as it pushes westward
across the Pacific, reaching tropical depression strength before
impacting the Hawaiian Islands in a Tuesday-Wednesday timeframe next
week. Soaking/flooding rains and subsequent flash flooding can't be
ruled out in Honolulu by the middle of next week.
Summary: our goal
is to set expectations, and although Dorian is fairly unimpressive
(today) we need to continue to collectively monitor this storm, and
possible implications for the U.S. Florida stands the best chance of
soaking rains from Dorian by the middle of next week; a solution that
brings Dorian into the Gulf of Mexico could threaten much of the Gulf
Coast with a much more significant storm or possible hurricane. Again,
it's too early to make a long-term determination of impacts or possible
U.S. landfall at this time. Flossie will probably spark considerable
flash flooding over Hawaii by Tuesday-Wednesday of next week. I'm
tempted to get on a plane and personally coordinate preparation efforts
on Waikiki Beach, but - alas - there's a high probability that won't
happen. I'll keep you in the loop with updates - hopefully Dorian's
long-term track will emerge from the meteorological noise within the
next 48-72 hours.
Ex-WCCO Anchor Don Shelby Mulling A Run For Congress. Hot Dish Politics at

Former
WCCO news anchor Don Shelby is reportedly mulling a run against
three-term Republican Rep. Erik Paulsen next year, potentially putting
in play a suburban Minneapolis

Drinking Coffee May Reduce Risk Of Suicide In Adults. Another eyebrow-raising article; here's an excerpt from The
Harvard School of Public Health: "
Drinking
several cups of coffee daily appears to reduce the risk of suicide in
men and women by about 50%, according to a new study by Harvard School
of Public Health (HSPH) researchers. The study
was published online July 2, 2013, in The World Journal of Biological
Psychiatry. “Unlike previous investigations, we were able to assess

Cancer Risk Increases With Height. Here's a clip from the "Well" blog at
The New York Times: "
A
woman’s cancer risk appears to increase with her height, a new study
shows. An analysis of 20,928 postmenopausal women showed that the taller
a woman is, the greater her risk for a number of cancers, including
breast, colon and skin cancer, among others. The finding,
published in Cancer Epidemiology, Biomarkers & Prevention, is not
expected to change screening recommendations and shouldn’t alarm those
with a tall stature. Instead, say scientists, the association between
height and cancer may help guide researchers to study hormones and
growth factors that influence height and may also play a role in cancer..."

Which U.S. City Has The Worst Drivers? O.K. Boston
would get my vote, and I've heard some crazy stories from my father
about driving in Detroit (at least in a German-built vehicle). The
answer didn't surprise me too much, come to think of it.
Slate has the cautionary tale - here's an excerpt : "...
Still,
the Allstate report is both a useful indicator and a good way to
winnow down the candidates. We can safely assume that the city with the
worst drivers is somewhere in Allstate’s bottom 50. Phoenix,
Indianapolis, and Denver, therefore, are off the hook, along with a raft
of others. One notable escapee is San Diego, the city with the most drunk driving arrests.
Let’s also ignore cities with populations below 150,000, because data
on those places is limited. Plus, few people have ever said, “Hayward,
California has the worst drivers!” We’ll add Boston back into the mix,
based on opinion surveys. (You’re not getting off that easy, Boston.)
That leaves 39 candidates..."

Climate Stories...
Global Warming And The Future Of Storms.
The Guardian has the story, co-authored by St. Thomas climate scientist John Abraham. Here's an excerpt: "...
I asked Dr. Emanuel to summarize the present understanding of hurricanes, and he responded with the following insights:
• The incidence of high-intensity tropical cyclones
(Safir-Simpson categories 3-5) should increase, and the amount of
rainfall in these storms should increase, upping the potential for
freshwater flooding. These changes will not necessarily occur where
tropical cyclones develop and thrive today. "Indeed," wrote Emanuel,
"it is likely that there will be decreasing activity in some places,
and increasing activity in others; models do not agree on such regional
changes."
• Though experts disagree on this point, Emanuel's work suggests
that weak events (tropical storms and Cat 1-2 storms) will become more
frequent.
• "Very little work has been done on the problem of storm size,"
wrote Emanuel, "what little research has been done suggests that storm
diameters may increase with global temperature. This can have a
profound influence on storm surges, which are the biggest killers in
tropical cyclone disasters..."

Desert Storm: Battle Brews Over Obama Renewable Energy Plan.
National Geographic Daily News has the story; here's the introduction: "
America's
deserts are stark, quiet places, where isolation and the elements have
long kept development at bay. To outsiders, these arid expanses may
not seem like prized land. But they are poised to play a key role—and perhaps, to serve as a battleground—in President Obama's plan to double U.S. electricity from wind, solar, and geothermal sources
by 2020. To help ramp up that amount of clean energy, the White House
has urged approval of an additional 10,000 megawatts of renewable
energy production on public lands. Estimates vary on exactly how many
households would be served by the expansion, but the Obama Administration says
the 25 utility-scale solar facilities, nine wind farms, and 11
geothermal plants it has approved on federal lands so far will provide
enough juice to power 4.4 million homes. One thing is for certain: The
new drive for large-scale solar will require land..."

Fossil Fuels To Dominate World Energy Use Through 2040. Meteorologist Andrew Freedman has the story at
Climate Central; here's an excerpt: "
Global
energy consumption will grow by 56 percent by 2040 with fossil fuels
remaining dominant energy sources. Along with that growth will come
increased carbon dioxide emissions and a continued reliance on coal,
oil, and natural gas for transportation and electricity generation,
according to a new report published Thursday by the Energy Information Administration (EIA). The International Energy Outlook,
which is released every two years, shows that strong economic growth
in developing countries will be the dominant force driving world energy
markets during that period. “Rising prosperity in China and India is a
major factor in the outlook for global energy demand. These two
countries combined account for half the world’s total increase in
energy use through 2040,” said EIA administrator Adam Sieminski in a
press release. The EIA is the Department of Energy’s statistical and
analytical agency..."
Former CIA Director: Fixing The U.S. Energy Strategy. Here's a clip of an interesting Op-ed at livescience.com: "...The
key to reducing the political and economic cloud of questionable
fuel-vending nations is to reduce overall demand - and, thus, the market
price and profits - for oil. While we can't take millions of
conventional-fuel vehicles out of the U.S. fleet overnight, there may be
cheap and effective ways to accelerate the use of alternative fuels and
increase energy independence. In particular, Woolsey believes in the
potential for a market for ethanol and methanol derived from U.S.
natural gas. With the current price of natural gas sitting around
one-fifth that of oil, developing methanol-based fuels to add them as a
choice at the pump could potentially take enough demand away from oil to
drive prices down to $60 per barrel or less....

Mohave Mirrors: World's Largest Solar Energy Ready To Shine.
National Geographic has the story; here's the intro: "
More than six years in the making, the Ivanpah plant is now slated to begin generating power before summer's end. It was designed by BrightSource Energy
to use more than 170,000 mirrors to focus sunlight onto boilers
positioned atop three towers, which reach nearly 500 feet (150 meters)
into the dry desert air. The reflected sunlight heats water in the
boilers to make steam, which turns turbines to generate
electricity—enough to power more than 140,000 homes.."

Buffet Says Coal's Decline In U.S. To Be Gradual But Permanent. Bloomberg Businessweek has the story; here's the introduction: "
Coal
use in the U.S. will continue to fall though the slide will be gradual

years,” billionaire Warren Buffett said at an event in Indiana this
week. “Coal will gradually decline in importance, and of course when
natural gas prices get low enough you have a big switch over,” Buffett
said July 22, according to a recording posted online by WFYI, a public
radio station in Indianapolis. “Coal plants are producing about 38
percent of all the electricity in the United States now,” Buffett said.
“You can’t scrap that. That takes years and years and years to replace.
It will be happening gradually...”
