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 Wednesday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good day wherever you happen to be spending it.

It’s clear over Kula, with a cold low temperature of 47.5 degrees according to my outside temperature sensor…along with an occasional gust of wind from the south-southwest.

8am, clouds are increasing rather quickly as this cold front pushes down through the state.

1212pm, it’s cloudy and getting more gusty here in upper Kula, with the rain along the leading edge of the approaching cold front just reaching the western tip of Molokai now.

129pm, the rain has moved over Molokai and Lanai, and has moved into the west side of Maui.

252pm, the rain has reached Wailea, Kihei and Maalaea, and will continue to progress over the rest of Maui.

310pm, the first drops have arrived here in upper Kula…with the temperature a chilly 64.2 degrees.

605pm, cloudy with light showers and fog, along with a chilly temperature of 60.6 degrees…after a high of 68.5 degrees.

Hawaii’s Broad Brush Weather Overview:  A weakening cold front will stall and dissipate in the vicinity of the Big Island Thursday. Trades return briefly. Trades return briefly Friday into Saturday, before they are disrupted again by another cold front approaching from the northwest.

Hawaii’s Weather Details:  Impressive post-frontal inversion at Lihue sounding, is a testament to dry air and strong subsidence wrapping into the area in the wake of the cold front. Dewpoints, already in the low 60s and upper 50s over Kauai and Oahu, will continue falling through tonight, paving the way for crisp and cool conditions this evening into early Thursday. The front, now over Maui County, will gradually dissipate as it loses forward momentum due to the loss of upper-level support. Showers will diminish in coverage as shallow moisture lingers in the vicinity of the Big Island through the end of the week.

On Thursday, light northwesterlies give way to sea breezes, though interior clouds may be hard to come by given the extremely dry state of the boundary layer. The exception will be the Big Island where lingering moisture will mix upslope during daytime heating, yielding typical extensive cloud cover and a few interior showers. Dewpoints then rebound and the chance for windward and mauka showers increases as frontal moisture shifts westward into central and western portions of the island in response to the return of moderate trades.

The next round of upper-level energy then potentially pushes the frontal zone eastward back through the area. The final position of this remnant frontal zone may ultimately be important, as it potentially serves as a focus for rainfall late next week.

Fire weather:  Winds are forecast to remain below the critical levels while a reinforcing shot of dry air causes afternoon relative humidity values to fall to near or slightly below 40 percent Thursday and Friday. In addition, rainfall associated with a passing front will help to mitigate the fire weather concern. Critical fire weather concerns are not anticipated.

Hawaii’s Marine Environment:  A cold front over Kauai will continue to move southeast around 15 to 20 knots. Gentle to moderate southwest to west kona winds are expected to develop in advance of the front. The front is expected to continue to move southeast over Oahu waters, and Maui County waters with time. The front will likely be weakening and slowing in forward speed after crossing Oahu, dissipating near the Big Island Thursday. The front will bring a relatively brief period of rainfall, near gale force winds, and the potential for thunderstorms and heavy showers, mainly over Kauai and Oahu waters.

A short-lived period of strong northwest winds following the frontal passage (with a longer-lived increase in seas) has prompted the issuance of a Small Craft Advisory (SCA) for many waters into Thursday. Winds will diminish as the front dissipates, with a surface ridge moving over the islands from the west by Thursday night. A surface high will pass north of the islands Friday into Saturday, supporting a moderate east- northeast trade wind flow. Long range guidance indicates the potential for another frontal passage late in the weekend.

A new moderate long period northwest swell will build. Buoys located at Hanalei and Waimea Bay have begun to pick up the long period forerunners. Surf along north and west facing shores are expected to stay just below High Surf Advisory (HSA) conditions as the swells remain from the northwest. Surf is expected to be larger Thursday and Friday over north facing shores, as a developing storm low continues to intensify due north of the islands near 32N.

The mix of 8 to 14 second north-northwest to north swell will make for jumbled surf as it overlaps with the diminishing longer period northwest swell. A HSA for select north facing shores and a SCA over most windward waters may need to be issued coinciding with the new swell. This swell will be slow to decline into the weekend, as the low will remain nearly stationary. Additionally, a weaker low north of the islands has generated a short-period (8-10 seconds) northeast swell that will peak before diminishing Thursday. A new northwest swell is possible next Monday, otherwise no other significant swells are expected.

Interesting:  Smaller Fish Offer Better Nutrition, Lower Environmental Cost

Smaller fish species are more nutritious, lower in mercury and less susceptible to overfishing, a Cornell-led research team has found.

The team’s study was conducted in the Amazon River, but the findings have implications for biodiversity conservation and public health across the globe as large fish species populations are declining worldwide.

The study, “Accessible, Low-mercury and Nutritious Fish Provide Win-Wins for Conservation and Public Health,” published January 17 in One Earth. It was authored by four Cornell researchers and colleagues from Brooklyn College and the Wildlife Conservation Society, a nongovernmental organization.
