Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are 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.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Saturday comments:  I’m here at home in upper Kula, Maui

It’s mostly clear with some cloudy areas early this morning, with a very cold low temperature of 37.5 degrees at my place…this breaks my low temperature record of 37.9 degrees many years ago!

1pm, it’s another of those warm in the sunshine and slightly cool in the shade days…like yesterday. It’s sunny, except for a few clouds along the windward sides.

925pm, it’s very clear here on Maui, with a million stars shining down! The temperature isn’t as cold as last night, although nonetheless, my thermometer is reading a very chilly 46.4 degrees.

Hawaii’s Broad Brush Weather Overview:  Trade winds will gradually ease and turn southerly early next week as high pressure shifts east of the state, allowing temperatures and dew points to slowly rise. Rainfall should be limited as a relatively dry and stable air mass remains in place. Forecast confidence decreases by mid-week as a cold front may move partway down the island chain Wednesday into Wednesday night, potentially bringing increased showers.

Hawaii’s Weather Details:  An expansive deck of fair weather stratocumulus clouds continues to stream into windward and mauka areas across the island chain, clearly evident on satellite imagery. This stable cloud layer has kept skies scattered to mostly cloudy in those areas, though it has produced very little rainfall so far, nor is it expected to.

In the wake of Thursdays cold front, a cooler and noticeably drier air mass settled over the region, bringing slightly below- normal temperatures and lower dew points. This wont last much longer. As the surface high roughly 350 miles north of the state slides east, and the next cold front approaches from the northwest, moderate to locally breezy easterly trade winds will gradually weaken and turn more southerly from Monday into Tuesday.

As winds ease and shift, temperatures and dew points should slowly climb as the air mass becomes modified by the warm tropical waters surrounding the islands. Despite these changes, rainfall is expected to remain limited through Tuesday, as moisture stays scarce and the atmosphere remains fairly stable.

By mid-week, the forecast becomes less straightforward. Model guidance begins to diverge, lowering confidence from Wednesday onward. Both the GFS and ECMWF models suggest a cold front may move at least partway down the island chain Wednesday into Wednesday night, which would bring an increase in shower coverage near the boundary.

How far south the front ultimately gets, whether it reaches the Big Island, or whether it weakens and lifts back to the northeast, remains uncertain given the wide model spread. Because of this, the details for the latter half of the week and into next weekend are still up in the air, and the forecast will evolve over the coming days.

Hawaii’s Marine Environment: A high pressure system north of the state will track east over the next couple of days, maintaining stable moderate to locally strong trade winds. The northeasterly winds will becoming more easterly through Sunday. By late Sunday into early next week, winds will weaken and veer southerly, becoming light to gentle by Tuesday, as a cold front approaches from the northwest. This next front could start moving through the coastal waters as early as late Tuesday afternoon.

A fading extra large northwest swell continues to produce high seas above advisory levels. Seas from the swell are expected to drop, thus can expect most waters to drop out of the SCA, expect for typically windy areas around Maui County and the Big Island.

The extra large, medium to long period northwest (320-340 degrees) swell which peaked Friday, continues to fade. Near shore buoys show lots of energy in the 12-16 band range which is why the High Surf Warning was downgraded to a low end High Surf Advisory (HSA) for north facing shores of Niihau, Kauai, Oahu, Molokai, and Maui. Surf has declined below advisory levels for west facing shores. This swell will continue to transition to a more northerly direction (350-010 degrees) as it fades.

A moderate northwest swell (320 degree) is expected to arrive Sunday into Sunday night. This swell looks to briefly bring surf heights well above advisory levels for north and west facing shores. Tuesday through through mid-week next week shows a series of overlapping moderate, west-northwest swells that will keep surf along north and west facing shores elevated.

Rough, choppy surf along east facing shores will hold for the next couple of days. Additionally, some east facing shores sensitive to northerly swells may experience a slight uptick in surf heights this weekend, as the fading northwesterly swell becomes more northerly. No noteworthy swells are expected for the next few days for south facing shores.

Interesting:  Locust Swarms Destroy Crops — Scientists Found a Way to Stop It

Study believed to be the first to test this method in real-world farming conditions; soil amendments resulted in fewer locusts, less damage and a doubled crop yield.

“They’re very destructive when there’s a lot of them, but one on one, what’s not to love?” Arianne Cease says.

She’s talking about locusts.

As the director of Arizona State University’s Global Locust Initiative, Cease has a healthy admiration for these insects, even as she studies ways to manage locust swarms and prevent the destruction they cause.
