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.

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

It’s clear to partly cloudy early this morning here at my location, with a low temperature of 51.5 degrees, and the relative humidity is 83%.

922am, it’s partly cloudy here on Maui, with gusty trade winds in those exposed locations.

1212pm, I played pickleball this morning in Makawao, which was very fun!

Hawaii’s Broad Brush Weather Overview…as of 1001am Wednesday:  High pressure northeast of the state will continue to bring locally breezy easterly trade winds today. Brief passing showers will favor mainly windward and mountain areas at times.

Tonight through the weekend, trade winds will ease slightly and veer to a more east-southeast direction, as a front stalls northwest of the state. This will help focus shower activity along east and southeast facing slopes, and interior areas of most islands during the afternoons. However, overall rainfall amounts are expected to remain limited. An approaching cold front may bring breezy southerly wind flow and unsettled wet weather by early to mid- next week.

Short Term Update…as of 1001am Wednesday: After another wet start to the day for many windward and mountain areas, and even some leeward areas, as a steady stream of light showers moved in on the trades overnight, shower coverage is once again beginning to diminish across the state at the time of this mid morning update. With high pressure building to the northeast and a cold front gradually approaching from the northwest, the breezy trades are expected to veer slightly out of east-southeast by tonight.

This slight shift in the steering flow along with the partial wind blocking of the smaller islands, will lead to some cloud build ups, leading to the development of a few light showers over their leeward/interior areas. In addition, some of the high resolution model guidance hints at some showers moving into leeward portions of Oahu today and tomorrow as small boundaries of low level convergence develop downwind of each island.

Hawaii’s Weather Details…as of 352am Wednesday:  A 1031 millibar high positioned well northeast of the state helped maintain moderate to locally breezy easterly trades last night into early this morning. Radar has been fairly quiet with isolated light showers affecting mainly windward locations. Several windward and mountain stations have reported accumulation, though generally below a tenth of an inch. Expect little change in the overall pattern today, as the aforementioned high slowly drifts eastward. After a brief lull in shower activity this afternoon, there should be an increase in coverage again after sundown.

Thursday through this weekend, a cold front approaching the islands from the northwest will prompt easterly trades to weaken and veer east southeasterly. In this pattern, showers tend to favor southeast and east facing slopes of the Big Island and Maui, along with interior portions of the other islands, due to the development of afternoon sea breezes in the lighter, blocked flow. Model guidance stalls the front west of the state, then eventually lifts it to the north.

Early next week, another cold front will approach Hawaii from the northwest. Ahead of this feature, the wind flow will veer more southerly and begin to carry deep tropical moisture into the region. By mid-week, both the GFS and ECMWF models agree in deepening this unstable moisture band across the state, especially over the western islands.

However, there is still much uncertainty in strength and timing of this next storm. The GFS generates a much stronger system, with a deeper parent surface low and greater upper level support. The ECMWF depicts a weaker parent low, less moisture, and a majority of the upper level forcing residing farther north of the state. Though the potential for heavy rain, thunderstorms, and strong southerly winds exists, details will need to be ironed out in the next few days, as models come into better agreement.

Hawaii’s Marine Environment…as of 352am Wednesday:  Trade winds will strengthen into the fresh to strong range and become increasingly easterly, as surface high pressure strengthens far northeast of the islands. Tonight into Thursday, winds will veer out of the east-southeast around Oahu and Kauai, as the high drifts eastward and a front approaches the state from the northwest. A Small Craft Advisory (SCA) remains in effect for most of the waters around the Big Island and Maui through Thursday morning where winds will be strongest.

The SCA has been extended through Thursday evening for the waters around the Big Island and Alenuihaha Channel, as winds further north weaken slightly as they veer. Portions of the coastal waters will continue to see SCA conditions through the weekend. Local winds may veer from a more southerly direction early next week, as a cold frontal low slowly advances toward the islands from the west.

A small northwest swell will continue to decline through Thursday. A new small overlapping west-northwest swell will arrive late Thursday and hold through the weekend, which will cause another rise in surf along north- and west-facing shores. This will be followed by another small west-northwest swell early next week. There may also be very small northerly swell late this week into the weekend.

Choppy east shore surf will builds to near seasonal average as trade winds strengthen over and east of the islands. Little change is expected along east facing shores through the weekend, followed by a possible decline early next week, as winds veer increasingly southerly. Surf along south facing shores will remain small to tiny through the weekend, and some islands may see an increase in choppy surf if southerly winds develop early next week.

Interesting:  Mapping the Future of Wildfires in a Warming World

How can scientists better assess the effects of a warming climate on wildfire behavior, fire risk, and long-term fire trends? A new review co-authored by Yale School of the Environment senior science researcher Jennifer Marlon outlines how climate change is reshaping wildfire patterns worldwide. The review, published in Science Advances, also details why understanding these shifts is essential for forecasting future risks.

“We’re seeing landscape fires increasingly threaten human health and property in ways that demand urgent attention,” Marlon said.

The paper, “Gazing into the flames: A guide to assessing the impacts of climate change on landscape fire,” brings together research from wildfire scientists across Australia, Europe, Canada, and the United States to focus on “the art and science” of projecting climate change impacts on landscape fire, including how fire’s drivers and impacts are modeled and how projections of the climate system are developed. Drawing on decades of fire research, satellite observations, climate model projections, and landscape fire modeling, the authors argue that traditional approaches fall short unless they integrate ecological, climatic, and human drivers.
