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 Tuesday 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 46 degrees according to my outside temperature sensor.

In addition to the low clouds that formed over the islands, prompted by the daytime heating of the islands, we have a new batch of streaky high cirrus clouds arriving from the northwest.

It’s already down to 49.4 degrees at 835pm, after a high today of 68.5 degrees.

Weather Wit of the day:  Daylight Saving Time – A light preserver

 

Hawaii’s Broad Brush Weather Overview:  Light and variable winds will allow land breezes to develop overnight, helping to clear clouds and any showers out of leeward and interior areas. A cold front will bring a brief round of showers and perhaps isolated thunderstorms Wednesday morning into Thursday. This will be followed by a shot of cooler weather. Trades return briefly Friday into Saturday, before they are disrupted again by another cold front approaching from the northwest.

Hawaii’s Weather Details:  Radar and satellite imagery show clouds and a few showers building over leeward slopes and island interiors due to sea breeze activity. Even with these clouds and showers, the local atmospheric environment around Hawaii is relatively dry and stable…with this afternoon’s upper air soundings showing inversion heights around 5,000 to 6,000 feet at both Hilo and Lihue and slightly below average precipitable water values.

Light winds will continue into the overnight hours as an approaching cold front from the northwest (currently about 250 miles away from Kauai) and a persistent surface low to the east-northeast help to weaken the local pressure gradient. This lighter flow will allow for land breezes to develop overnight, which will help to clear out cloud cover over leeward slopes and island interiors.

Model guidance shows an upper-level trough shifting south, forming a cutoff low just to the north of the state, and bringing the aforementioned cold front to Kauai`s doorstep by early Wednesday morning, to Oahu by mid-day, then showing it gradually moving down the rest of the island chain through Thursday, and then stalling near the Big Island. Showers will form along the frontal boundary and while some may produce locally heavy rainfall, they are expected to clear out relatively quickly as moderate to locally breezy northwest winds behind the front usher in a shot of drier air.

There remains some uncertainty regarding how far south this drier airmass will penetrate, with confidence decreasing the further south down the island chain it goes. In addition, thunderstorms will be possible with this frontal passage, due to the modest instability and moisture in place as the cloud band moves through. The forecast continues to show isolated thunderstorms along the frontal boundary, as it starts to move down the island chain, then keeps it mostly over the eastern waters as the front weakens and gradually progresses further south.

On Thursday, the western end of the state will be cool and dry, while the front dissipates over the Big Island and its remnant moisture lingers over the eastern end of the state. By this point, the upper level low will have deepened and brought lower temperatures aloft across the island chain. This instability combined with lingering moisture and daytime heating may be enough to bring an isolated thunderstorm or two to the Big Island Thursday afternoon, but chances are low.

On Friday, winds will veer easterly and strengthen to moderate levels, as high pressure builds just north of the state. At the same time, moisture that was being pulled north across the eastern North Pacific earlier in the week, will get pushed across the island chain in the redeveloping trades. That plume of moisture along with the remnant moisture from the dissipated front will increase the chance of windward  showers Friday into Saturday. The pressure gradient will weaken again Saturday into Sunday in response to another approaching cold front from the northwest, disrupting the trades once again and bringing lighter winds across the area.

Forecast confidence decreases Sunday night and beyond due to model discrepancies. The general pattern looks to be similar to what we will see Wednesday as another trough digs down across the Central Pacific, spawning a surface low that will drag a front into our area. However, the strength of this upper-level trough and resulting surface low is a bit uncertain, and model guidance is hinting at an area of prefrontal convergence that could bring rain to the western end of the state ahead of the next front.

Fire weather:  Winds are forecast to remain below the critical levels while a reinforcing shot of dry air causes relative humidity values to fall to near or slightly below 40% Thursday and Friday. However, if the lower relative humidity values move in faster to match up with the breezy northwest winds immediately behind the front, there may be a brief period of concern. Even so, rainfall associated with this front will help to mitigate the fire weather concern. Beyond Friday, critical fire weather concerns are not anticipated through the rest of the forecast period.

Hawaii’s Marine Environment:  Trade winds will diminish with light and variable winds over most of the waters as a surface ridge to the north is weakened and pushed southward. A frontal passage is expected to move down the island chain Wednesday and Thursday, bringing a period of rainfall and possible thunderstorms. A brief period of fresh prefrontal south to southwest kona winds is excepted on Wednesday, mainly over the eastern half of the island chain. Following the frontal passage, moderate to strong northwest to north winds will result in localized accelerations through channels and leeward areas, prompting the need for a Small Craft Advisory (SCA) for select waters Wednesday and Thursday. Winds will diminish late Thursday and Friday as the front stalls then dissipates near the Big Island. A brief return of trade winds is due on Saturday.

The current northwest swell will continue to decline and forerunners of another northwest swell will arrive late tonight. This swell will slowly build through Wednesday and peak Wednesday night and Thursday, leading to High Surf Advisory (HSA) conditions across most north and west facing shores from Kauai to Maui, and SCA level seas over exposed waters. As this swell declines late Thursday and Friday, a storm low centered well north of Hawaii will send a medium period north swell that could produce HSA surf for north shores. The north swell will lower through the weekend, and may be followed by a moderate to large northwest swell next Monday.

East shore surf surf will decline slightly as trades diminish, though a small pulse of short period northeast swell is expected through Wednesday. Aside from areas exposed to wrapping north swell Thursday into the weekend, east shore surf will be small. Surf along south facing shores will remain tiny as it returns to typical wintertime conditions for south shores. A tiny pulse of south-southwest swell is possible for the weekend.

Interesting:  Research on Past Hurricanes Aims to Reduce Future Risk

Tropical storms like hurricanes are not only terrifying, but also incredibly costly for coastal regions across the United States, Mexico, Central America and the Caribbean. Beyond the immediate devastation, these storms contribute to significant economic losses and human displacement. In 2023 alone, climate migration linked to such events saw 2.5 million individuals attempt to cross the U.S. southern land border.

New research led by The University of Texas at Arlington emphasizes that studying the impacts of past tropical storms can help communities better prepare for future storms. A key part of the study is analyzing the types and quantities of storm-related precipitation in affected regions to understand its role on local water resources. By mitigating excessive damage, such preparation could enable more people to remain in their home countries. This is increasingly urgent as climate change is expected to make tropical storms 10-15% more frequent and intense.
