~~~ Hawaii Weather Narrative ~~~
Our local trade winds will be moderately strong, becoming lighter Friday into the weekend…then rebounding Sunday into early next week. Here’s a weather chart showing a large near 1032 millibar high pressure center to the northeast of our islands. This high pressure system has an elongated ridge of high pressure extending southwest…well offshore to the northwest of our islands. There are a couple of low pressure systems just to the northwest of this ridge, which are pushing it closer to us. This in turn will begin to soften our winds, especially by Friday and Saturday, and will veer them to the southeast…carrying volcanic haze (vog) over some of the smaller islands.
There will be showers falling locally, which will become somewhat heavier at times…into Friday. Satellite imagery shows lower level clouds over and around the islands. There’s also brighter white, higher level clouds, some of which are towering cumulus over the offshore waters to the north and north and south of the islands. Here’s the looping radar image, showing generally light to moderately heavy showers over the offshore waters, being carried to our windward sides on the trade wind flow locally. The expected heavier showers haven’t shown up yet, although the threat of those localized downpours isn’t over yet…especially over Kauai and Oahu.
We find an upper level low pressure system near Kauai…which will gradually move eastward across the Aloha State. This will make our atmosphere unstable, keeping the state more shower prone than normal. As this low shifts eastward, we should see the shower activity, which has been somewhat limited of late…increase at times on all of the islands with time. A thunderstorm or two isn’t out of the question. Our winds will begin to shift from the current moderately strong realms, to lighter levels Friday and Saturday. These lighter breezes will prompt convective clouds to grow over the islands, leading to tall cloud buildups, and locally heavy showers…over the leeward slopes during the afternoon hours. As the winds become lighter, they will also veer to the southeast, which will bring volcanic haze (vog) over some parts of the state…and make our lower elevations feel rather muggy too. The trade winds will become stronger again by Sunday into early next week, perhaps ushering in a wet trade wind pattern for several days. I’ll be back with your next new weather narrative early Thursday morning, I hope you have a great Wednesday night wherever you happen to be spending it! Aloha for now…Glenn.
World-wide tropical cyclone activity:
Atlantic Ocean: There are no active tropical cyclone
A BROAD AREA OF LOW PRESSURE IS LOCATED OVER THE EASTERN TROPICAL ATLANTIC A FEW HUNDRED MILES SOUTHWEST OF THE CAPE VERDE ISLANDS. THIS SYSTEM HAS CHANGED LITTLE IN ORGANIZATION OVER THE PAST SEVERAL HOURS...BUT SOME DEVELOPMENT IS POSSIBLE DURING THE NEXT DAY OR TWO BEFORE UPPER-LEVEL WINDS BECOME LESS CONDUCIVE. THIS SYSTEM HAS A MEDIUM CHANCE...30 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS...AND A MEDIUM CHANCE... 40 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 5 DAYS WHILE IT MOVES SLOWLY WESTWARD TO WEST-NORTHWESTWARD.

Interesting: U.S. will see unprecedented heat waves by mid-century - Just how soon will climate change become really obvious? A new study, using data from 39 climate models, predicts unprecedented heat waves will hit the tropics by 2020 and the U.S. as early as 2043.
Steady, unprecedented heat waves could soon hit many parts of the planet, striking the tropics first — as early as 2020 — and much of the United States by mid-century, says a study today that’s based on models from 21 climate centers worldwide.
So in 2043, for example, Phoenix and Honolulu could see their average air temperatures shift beyond the most extreme records of the past 150 years if greenhouse gas emissions continue at their current pace, says the study published in the peer-reviewed journal Nature. That could occur in 2047 for New York City, Philadelphia and Washington, D.C., and in 2048, for Los Angeles and Denver. In other words, whatever the record warmest year was for those cities before then, every year after that point will likely be warmer.
“What’s shocking is how soon this is going to happen,” says lead author Camilo Mora,a data analyst and geography professor at the University of Hawaii, Manoa. “This is something we’re doing to ourselves,” not just to future generations, he says, adding that within 35 years, “whatever climate we were used to will be a thing of the past.”
His team developed an index, based on data from 39 climate models used in 12 countries, for when the climate of any spot on Earth will continuously exceed the extremes recorded between 1860 and 2005. They found that the planet’s oceans began surpassing historical extremes for acidity in 2008, because they’ve absorbed significant amounts of human-caused carbon dioxide emissions.
The study says the world’s climate is already changing, but the index — a sort of tipping point — shows when a “radically different climate” could begin for any particular location. It says the onset could be delayed if heat-trapping emissions are curbed.
“This paper is unusually important,” Jane Lubchenco, former head of the National Oceanic and Atmospheric Administration and now professor at Oregon State University, said in a statement. She said the study, which she did not work on, “connects the dots between climate models and impacts to biodiversity in a stunningly fresh way.”
Stuart Pimm, a professor at Duke University’s Nicolas School of the Environment, agrees. He says the findings may seem counter-intuitive, because the Arctic is warming more than the tropics. Yet he says the Arctic is used to rapid change but the tropics are not, so the latter is departing from historical norms sooner.
“That’s going to cause societal disruptions,” Pimm says, noting there’s more ecological biodiversity as well as human poverty in the tropics than in the Arctic.
The study projects Indonesia could see a huge shift beginning in 2020, and Malaysia’s Kuala Lumpur as well as Nigeria’s Lagos in 2029. It says extreme climates, especially in the tropics where more than a billion people live in predominantly developing countries, raise concern about food shortages, wider spread of infectious disease and species’ extinction.
“We will push marine ecosystems out of their historical “habitable zones,”" if current trends in greenhouse gas emissions continue, says Ken Caldeira, a climate scientist at the Carnegie Institution for Science, who was not involved in the study. He says some species may be able to adapt but others, such as coral reefs, likely won’t.
Caldeira says that while there are “uncertainties” in the details of climate models, the study’s findings are “robust” and suggest the need to reduce greenhouse-gas pollution..
Mora said the university funded all the research except for a $5,000 NOAA grant for an advanced computer to do the data analysis. He says his team has no policy agenda but agrees emissions need to be curbed. Temperatures that were once the maximum will soon become the new minimum, he says, adding: “We’re not ready for it.’
