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 Monday 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 very cold low temperature of 44.5 degrees according to my outside temperature sensor.

Late morning, those high cirrus clouds that to our north earlier have shifted down over the state now.

Weather Wit of the day:  Daylight Saving Time – Just about the only thing anyone can save these days

 

Hawaii’s Broad Brush Weather Overview:  Look for dry and stable statewide weather conditions, with gentle trades, to continue through Tuesday. Limited shower activity will favor windward areas and mountain slopes. A significant pattern change may develop through the middle of the week, in response to an evolving northern upper trough digging south toward the islands. This in turn will increase precipitation chances, along with the threat for gusty southwest kona winds Wednesday into Thursday.

Hawaii’s Weather Details:  A dry, stable air mass and gentle trade winds will be the main theme during this holiday. Low temperatures will dip into the average middle 60’s under cloudier skies, with more windward shower activity, as a band of moisture entering our north nearshore waters passes by to the south. Morning atmospheric soundings depict this stable, unseasonably dry air mass, with near 0.9 inch precipitable waters, and a pronounced near 5,000 foot inversion.

It’s rare to see all of the island’s rain gauges remaining dry, either nil or just 0.01″ of rain (windward Big Island), these past 24 hours. With the lone exception of this ribbon of higher moisture moving south over the chain, and producing a bit more upper elevation shower activity today, many of these gauges will stay dry through Tuesday.

Mid to upper level ridging is moving in from the west, and this will maintain enough large scale stability to limit rainfall the next couple of days. After one more day of mainly gentle trades, Tuesday’s winds will back-off, as a weak area of low pressure east of the state slackens the gradient produced by high pressure northeast of the islands.

Weather models are in better agreement on the timing of a Central Pacific upper trough shifting south toward the state Wednesday. The general modeling consensus has a cold front passing across the island chain from Wednesday afternoon through late Thursday. Statewide rain chances ahead of the boundary will lift into the likely category, as gusty southwesterly kona winds strengthen across Oahu and Maui County Wednesday and Thursday.

There is a potential for downsloping winds on Oahu Wednesday. The uncertainly lies in the potential for a cut-off low to develop within the base of this trough and, if this happens, how long the low will meander north of the state. The evolution of this low and its future movement will be the main driver of any significant periods of heavy rain, possibly leading to flooding issues and/or strong damaging winds.

Temperatures well aloft will certainly be cold enough to decrease mid-week atmospheric stability, and introduce the chance for regional thunderstorm activity. Thus, impactful weather concerns will be the focused of locally high rainfall and strong gusty winds, along with proximity storms, will all be dependent upon the movement of a cut-off low meandering off to the north.

Weather conditions will begin improving on Friday, as the upper level trough/low lifts north and further away from the state. Winds will likely remain light to gentle out of the west. Moderate rain chances will remain active, especially east of Oahu, as higher mid to low level moisture lingers in the presence of weakening upper troughing. A Central Pacific trough is forecast to develop north of the state early next week. This trough may be deep enough to have its associated cold front passing over the islands next Monday or Tuesday.

Fire weather:  Dry conditions will persist through Tuesday. Trade winds will remain gentle to locally breezy at best, then weaken Tuesday into Wednesday as the state will be downstream of an approaching cold front. This front is forecast to move down the island chain Wednesday through Thursday. This front will produce much needed statewide rain. Hence, critical fire weather conditions are not expected this week.

Hawaii’s Marine Environment:  Surface high pressure passing just north has gradually weakened the trades to moderate to fresh speeds and will continue to weaken Tuesday. A cold front approaching and then moving into the islands Wednesday into Thursday will produce more variable winds along and ahead of the frontal band. The potential for unstable weather is possible, with isolated thunderstorms for coastal and offshore waters along the front. Northwesterly winds will build in behind the front as it passes through each island.

The current moderate northwest swell will continue to trend down just below High Surf Advisory (HSA) criteria along exposed north and west facing shores through Tuesday. Tuesday night, the next moderate to large northwest swell is expected to fill in, and produce High Surf Advisory (HSA) level surf along exposed north and west facing shores as it peaks Wednesday through Thursday, then slowly fades Friday into the weekend. An SCA will likely coincide with the swell for exposed coastal waters due to high seas.

East shore surf will remain choppy before slowly declining through the rest of the week, and background south swell will keep surf small on south facing shores through the week.

Interesting:  Researcher Studies the Power of Native Plants to Combat Road Salt Pollution

Salt pollution in freshwater is a growing global concern.

Excessive salt harms plants, degrades soil, and compromises water quality. In urban areas, road salts used for de-icing during winter often wash into stormwater systems, posing health concerns and challenges for infrastructure.

Specifically, salts can impact the processes like filtration and contaminate retention basins that are used to manage and treat urban stormwater runoff. Megan Rippy, assistant professor in civil and environmental engineering, is on a mission to understand how salt affects plants in stormwater detention basins and assess whether certain plants can mitigate salt pollution through a process called phytoremediation.

“Plants play an important role in green infrastructure performance, but only 1 percent of plants, known as halophytes, can handle highly saline environments,” said Rippy. “This makes it important to characterize the threat salts pose to green infrastructure as well as the potential of salt tolerant species to mitigate that threat.”
