Hawaii’s MountainsHere’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (nearly 13,800 feet high) on the Big Island of Hawaii. This webcam is available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars — and the sunrise and sunset too — depending upon weather conditions.

A counter-clockwise rotating low pressure system, with its cold front…is located far north of the state
We see an old cold front south, the tail-end of another front well north…and a new front northwest
Many clear areas over the islands, some windward cloudiness…lots of high clouds southeast
Showers locally…some are generous

~~~ Hawaii Weather Narrative

The smaller islands have been dominated by strong trade winds…although most areas remained below wind advisory criteria for sustained winds and gusts. The strong winds are being driven by strong high pressure cells, centered northeast and northwest of islands. The trade winds are expected to gradually weaken through Friday night, and maintain moderate breezes into the weekend. Passing showers moving along with the trades will focus over windward areas, although showers will reach over to the leeward sections of the smaller islands locally. Moisture associated with an old cold front is expected to be carried in with the trades Friday…although with limited rainfall expected.

Water vapor imagery shows an upper level trough of low pressure…with an axis passing over the Big Island. The instability provided by this upper trough, along with the moisture pushed upslope by sea breezes along the Kona coast…produced active showers and thunderstorms over the interior of the Big Island. Frequent lightning strikes were observed within these thunderstorms during afternoon hours. The expectation is that these thunderstorms will weaken and dissipate this evening into the night, as offshore flowing land breezes set in…and the upper trough of low pressure migrates eastward.

Another upper trough of low pressure will begin to move towards the state Sunday…and may bring another round of active weather Tuesday night or next Wednesday. However, there’s still significant uncertainty due to model differences. A surface low developing far north-northwest of the area will likely lead to a reduction in the trade winds.  Although it should be pointed out, that some of the models develop another low to the east of the islands…which leads to very light winds.  Despite these model differences, the current forecast keeps a light to moderate east-southeast air flow in place. Obviously there is low forecast confidence at this point in time, stay tuned.

Marine environment details: A satellite pass showed Small Craft Advisory (SCA) winds over most coastal waters. Gale conditions have dropped out of the Alenuihaha and Pailolo Channels…thus, the Gale Warning has been cancelled.

Unprecedented Arctic weather has scientists on edge
As station chief at NOAA’s Point Barrow, Alaska, observatory, Bryan Thomas works close to the edge of the Arctic Ocean. What he saw from his office in early February, looking north toward the horizon, was troubling.

“I could see what’s known as water-sky — the reflection of dark water on clouds on the horizon,” Thomas said. “From land, you can maybe see 10 miles, and the clouds were telling us that somewhere in that distance there was open water.”

Normally, there would be unbroken sea ice for hundreds of miles.

“Here we are in February, when we expect maximum sea ice extent,” Thomas added. “This might be all we’re going to get.”

The Arctic’s new abnormal

It’s a time of tumult in the Arctic, with record temperatures and extraordinary sea-ice conditions now becoming the norm. For starters:

  • Sea ice observed in January in the Arctic was the lowest in the 38 years of satellite record and 100,000 square miles less than 2016. That’s equivalent to the size of Colorado.

  • The average temperature of 4.4 degrees F in Barrow, Alaska, from November 2016 through January 2017 shattered the old record of 0 degrees set between 1929 and 1930. From 1921 to 2015, the average November-to-January temperature in Barrow was -7.9 degrees F.

  • Temperatures in the Arctic for the calendar year 2016 were by far the highest since 1900. Each of the past four years was among the top 10 warmest on record.

The late and faltering formation of sea ice this winter is one of many signs of extraordinary change in the Arctic, said Mark Serreze, director of the National Snow and Ice Data Center. He added that repeated surges of extremely warm air have stunted the growth of sea ice during fall and winter.

Melt season is dead ahead, and it’s not looking good

Will 2017 set a record for the least amount of sea ice ever recorded at winter’s end? Serreze said it’s probably a given: “We’re starting melt season on very, very bad footing.

What’s happening in the Arctic isn’t staying in the Arctic, added Richard Thoman, a meteorologist for NOAA’s National Weather Service Alaska Region. Profound changes are coming to the state’s interior as well.

“This winter was cold by today’s climate standards,” Thoman said. “By historic standards, it was completely uninteresting. I’m ready to say beyond any doubt that interior Alaska simply does not experience the temperatures it did in the past. “

The rapid changes are bewildering, even to scientists who’ve studied it for decades.

“We knew the Arctic would be the place we’d see the effects of climate change first, but what’s happened over the last couple of years has rattled the science community to its core,” Serreze said. “Things are happening so fast, we’re having trouble keeping up with it. We’ve never seen anything like this before.”
