Limits of Technology
By Paul Douglas
Technology will
save us from ourselves. A comforting thought, and it may even be true,
at least some of the time. I'm a techno-optimist but there are limits to
my exuberance.
Doppler radar, smart phone apps & social media
have created new ways to receive actionable weather intelligence - to
help make smarter weather decisions or take evasive action when severe
storms threaten. Yet many people don't heed the warnings until they can
SEE the tornado on the ground, or friends text/tweet them that the risk
is real.
Weather satellites update every 15 minutes, lulling
coastal residents into a false belief they can evacuate at the last
moment, if it turns out to be "a big deal" - not realizing the traffic
mess a mad-dash would create. Technology empowers. It can also lead to
overconfidence.
If I heard that "Bertha" was coming I'd probably
run for the hills, but Tropical Storm Bertha should stay out to sea. No
storms with names nearby; just a few T-storms sprouting by evening.
Soaking T-storms brush southern Minnesota late Tuesday and Wednesday,
then 80s return by late week.
We're on a time-delay. Now that it's August we're finally seeing the July we never had. Makes total sense.

Beatle Warning
Thanks
to my Aunt Kaye Kruse for the picture who attended Saturday night's
Paul McCartney concert last night at Target Field. It looked a little
sketchy early on, but rain/thunder dissipated before the concert got
underway.

Minneapolis Temperature Trend
Here's
a brief glance at temperatures over through mid August, which shows the
potential for a slight cool down (70s) by the second half of the week
ahead.
Sunday Weather Outlook
Not
a bad Sunday ahead... Very summer-like with warm temperatures and a few
spotty thunderstorms during the afternoon/evening hours. The image
below shows temperatures (80s) and weather conditions (spotty
thundershowers) by 5pm Sunday.
Duluth Aerial Lift Bridge
World's most inland seaport
Beach Day!
Yes,
it was a beach day!! I lived in Duluth for 4 years and we didn't get
too many days like that on Friday... The picture below was my view from
"Park Point" on Friday, which is the world's longest freshwater sandbar
(~6 miles long)!! I was trying to figure a way to bottle that up, so I
could open it sometime this winter.
Weather Outlook
Here's
the weather outlook through AM Monday. Note the week front sliding
through the Midwest - this will be responsible for a few spotty
showers/storms from PM Saturday through Sunday evening. Some of the
heaviest precipitation will be found along the Eastern Seaboard as a
front stalls there. Another area of abundant moisture will be found in
the Southwest where monsoonal moisture continues.
Precipitation Potential
According
to NOAA's HPC, the precipitation potential from AM Sunday through AM
Monday shows the potential of nearly 0.30" as the weak front slides
through. Keep in mind that some spots could see nothing, while some that
get a heavy downpour from any isolated thunderstorm could see nearly 1"
or more in a very short amount of time.
Raining in AZ
Thanks to Jody Musil out of Sun City Grand, AZ for the picture below where thunderstorm brought heavy rain rainfall and flash flooding to some of the surrounding areas.
North Shore Trip
I
recently got back from a trip along Minnesota's North Shore and the
views never cease to amaze me! For the first time, I made a trip with
the family to Grand Portage (Canadian border) to view the High Falls
along the Pigeon River and what a view! If you ever get a chance to get
up that way check it out and stop at the Mount Josephine overlook along
the way!
Tropical Update
Bertha
is the second named storm of the Atlantic Hurricane Season, which
officially started June 1st. The loop below showed the sunrise over
Bertha, which was located in the Caribbean when winds were sustained at
nearly 50mph.
Tracking Bertha
According
to NOAA's National Hurricane Center, Bertha should track northwest
towards the U.S. a bit before making a sweeping arc back over the open
waters of the Atlantic. There is a chance that Bertha could briefly
become a category 1 hurricane and 2 for 2 on hurricanes this season in
the Atlantic basin (Arthur was briefly a category 2 hurricane as it made
landfall with the Outer Banks of North Carolina).
Bertha Intensity Forecast
This
is an interesting look at a Bertha Forecast... it shows a number of
different model intensities for Bertha, which bring the storm close to
Hurricane Force (74mph) by midweek.
Hurricane Climatology
Bertha
is only the 2nd named storm of the Atlantic Hurricane Seaon, but
climatologically speaking, we're still about 1 month from the peak of
hurricane season (September 10th).
Tropical Update Continued...
Meanwhile,
Genevieve and Iselle were still playing a small role in the East
Pacific. By midday Saturday, there had been 9 named storms in the
Eastern Pacific, 4 of which were hurricanes; Amanda, Cristina, Hernan
and Iselle.
Super Typhoon Halong
Take
a look at this beast! According to the Joint Typhoon Warning Center,
Super Typhoon Halong had sustained winds of nearly 155mph with gusts up
to 190mph as of midday Saturday (EDT). This storm was equivalent to a
top end category 4 hurricane and makes it the 3rd super typhoon of the
Western Pacific Hurricane Season!! The eye with Halong was very
impressive! The good news is that Halong is expected to make a turn
north away from the Philippines Islands, which was hit by Super Typhoon
Haiyan earlier this season. However, the turn north could bring
hurricane conditions to southern Japan later this week.
Halong Track
Weather Outlook
Here's
the weather outlook through PM Monday, which shows more widespread
rain/thunder across the Eastern Seaboard and the Intermountain West. An
impulse of energy will slide through the Upper Midwest from Sunday
through Monday. One spot that needs moisture is California and it
doesn't appear that any relief is in sight anytime soon.
California Drought Worsens
Where
we need the moisture the most, we're not getting it. California has now
been upgraded for 36% of the state to 58% of the state under an
EXCEPTIONAL DROUGHT.
"We may have to migrate people out of California"
Here's
an interesting article from CNBC that quotes an academic chair at
Kaplan University that says "We might have to migrate people out of
California."
It's going from worse to worst each week in California. Suffering
in its third year of drought, more than 58 percent of the state is
currently in "exceptional drought" stage, according to the latest U.S.
Drought Monitor map. That marks a huge jump from just seven days ago,
when about 36 percent of the state was categorized that way. Exceptional
drought, the most extreme category, indicates widespread crop and
pasture losses and shortages of water in reservoirs, streams and wells. If
the state continues on this path, there may have to be thoughts about
moving people out, said Lynn Wilson, academic chair at Kaplan University
and who serves on the climate change delegation in the United Nations. "Civilizations
in the past have had to migrate out of areas of drought," Wilson said.
"We may have to migrate people out of California." Wilson
added that before that would happen, every option such as importing
water to the state would likely occur— but "migration can't be taken off
the table."

California Reservoir Levels
According to cdec.water.ca.gov
- a number of the reservoirs across the state are sitting about half
of the historical average. The only spots sitting at near historical
levels is Pyramid Lake in the southwestern part of the state.
Precipitation Needed to End Drought
The
graphic below shows how much precipitation may be needed to end the
drought and interestingly, some spots may need more than a foot of water
to end the drought in the Central Valley.
Central Valley Drought: North American Waterfowl Casualties
Here's
something that I came across that I thought was interesting; the
California drought is actually having a big impact on the North American
Waterfowl migrate to the Central Valley!
Add another casualty
to California’s prolonged and punishing drought: Wildlife officials
warned this week that dry conditions in the state’sCentral Valley could
have a devastating effect on North American waterfowl. The
Central Valley is recognized as the most important resting and
wintering ground on the Pacific Flyway, a global migratory path for
millions of ducks, geese and other birds. About 5 million waterfowl
spend the winter on state and federal wildlife refuge areas and flooded
rice fields in the Central Valley each winter.

Drought Monitor Continued...
Despite
the tremendous drought in the Western U.S., the Midwest is actually
doing quite well. As of last week, no parts of Minnesota were considered
to be in any drought or abnormally dry across Minnesota! In fact, we've
almost had too much rain so far this summer. 'No Wake' restrictions
were recently just lifted on Lake Minnetonka.
Spotty
showers were heaviest in the East, where rain benefited pastures and
summer crops. Meanwhile, mostly dry weather prevailed in the Midwest,
except for a few bands of locally heavy showers. Despite a July drying
trend, most Midwestern crops continued to thrive due to near- to
below-normal temperatures and abundant soil moisture reserves. On July
27, USDA rated three-quarters of the U.S. corn and 71% of the soybeans
in good to excellent condition—the highest such ratings this late in the
season since 2004. Farther west, hot weather on the Plains yielded to
sharply cooler conditions. In addition, rain overspread the central and
southern High Plains late in the drought-monitoring period. The spell of
hot weather hastened winter wheat maturation on the northern Plains and
promoted rapid crop development throughout the nation’s mid-section.
However, the Plains’ high temperatures also stressed some summer crops,
especially in areas dependent upon rain or with lingering subsoil
moisture deficits. Elsewhere, heat also arrived across the Southwest
during a temporary break in the monsoon circulation, while cooler
weather and beneficial showers overspread the Northwest. In particular,
Northwestern showers aided containment efforts for a rash of
lightning-sparked wildfires. However, the weather pattern reversed
during the second half of the drought-monitoring period, with heat
returning to the Northwest and a monsoon surge delivering heavy rain to
parts of the Southwest.
Looking Ahead
From
July 31 – August 4, locally heavy showers will shift eastward across
the South, eventually reaching the southern Atlantic States. Five-day
rainfall totals could reach 1 to 3 inches from Florida into the southern
mid-Atlantic region. Meanwhile, showers will linger across the central
and southern Rockies in the wake of a significant rainfall event. Most
of the remainder of the West will experience dry weather, except for
isolated showers across the Great Basin and Intermountain region. Mostly
dry weather will also prevail during the next several days from the
northern Plains into the middle Mississippi Valley. Elsewhere, an
ongoing heat wave in the Northwest will contrast with near- to
below-normal temperatures in most other parts of the country. The NWS 6-
to 10-day outlook for August 5 – 9 calls for the likelihood of
below-normal temperatures in large sections of the central and eastern
U.S., as well as the central Rockies, while hotter-than-normal
conditions will cover the lower Southeast, the lower Rio Grande Valley,
and the Far West. Meanwhile, near- to above-normal rainfall across the
majority of the U.S. will contrast with the likelihood of
drier-than-normal conditions in the Pacific Northwest, northern Plains,
far upper Midwest, and southern parts of Arizona, Texas, and Florida.
5 Day Precipitation Outlook
According
to NOAA's HPC, the 5 day precipitation outlook looks greatest along the
Eastern Seaboard where a stalled frontal boundary will be in place, but
there will also be pockets of heavy moisture in the Southwest and the
Midwest.
Temperature Outlook
According
to NOAA's Climate Prediction Center, the center of the nation still has
a fairly good chance of slightly below average temperatures in the 6 to
10 day range (August 7th-11th).
Thanks again for checking in and have a great rest of your weekend.
