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’s Broad Brush Weather Overview: Light to locally breezy trades with generally drier weather through Monday afternoon. Showers will focus along windward upslope terrain the next couple of days. There are increasing chances for more active weather from late Monday through Thursday, with higher probabilities for locally heavy rain with isolated thunderstorms.

Hawaii’s Weather Details: Broad upper ridging across the West Central Pacific has expanded just far enough east, along with a swath of drier air passing by from the east, to influence and stabilize our weekend weather here in the islands. IR satellite is depicting a lower level moist air mass advancing in on light to moderate trades. This will increase overall precipitation coverage today, but most of the light showers will briefly pass over windward communities, with the highest precipitation being confined to the upper elevations.

A weakened high pressure located northeast of Hilo is slowly settling southeastward. This will sustain a tight enough downstream pressure gradient to support light trades the next couple of days. Local atmospheric soundings are still showing a 6,000 to 7,000 foot boundary layer, underneath very dry mid to upper level air.

These factors equate to another couple of days of primarily dry, stable weather under partially sunny skies and light trades, locally breezy in higher terrain. Light precipitation will again focus along windward upslope mountains. Higher nocturnal rain accumulations will occur within a relatively thicker 8.000 to 9,000 foot moistened layer underneath a thick slab of dry air aloft.

A weakness will develop within the upper ridge over the islands Monday. An upper trough and associated cold front will approach the island chain from the northwest, and merge with the weakness channel over the state going into Tuesday. It is a bit early to determine the evolution of this trough, but it will more than likely pull up moist equatorial air northward over the islands, while destabilizing the regional atmosphere.

Weather prediction guidance has precipitable water (pwat) values nearing the upper 90 percentile for this time of year, being pulled up and over the islands from Monday through Thursday. Temperatures within the trough or upper low should be cold enough to destabilize the regional atmosphere enough to result in isolated thunderstorms Tuesday, roughly centered between the Kauai and Alenuihaha Channels.

The bulk of the higher pwat air is currently being modeled to be in the vicinity of Big Island and points east while the greatest instability exists west over the central and western islands. While the greatest moisture and highest instability may be slightly out of phase, confidence is mounting that the highest threat from thunder will anchor in the proximity of Oahu and Maui County, while the highest rainfall that could lead to flooding will focus on Big Island.

Another element that increases confidence of this potentially impactful, active mid-week pattern is the upper divergence forming along the eastern flank of the upper trough…opening up across the island chain. This upper forcing within a very moist air mass and destabilizing cooler mid to upper levels, should provide the necessary ingredients to prolong a very wet pattern through Thursday.

A drier late week as upper ridging begins to take hold. Re-established surface high pressure to the northeast will reintroduce strengthened trade winds Thursday and Friday. An upper trough and associated surface front will approach the state next weekend. This trough may pack enough of a punch to actually push our first cold front across the island chain early next week.

Freezing levels falling to around 12,000 feet, implies that a frozen mix or snow showers will occur within freezing surface temperatures atop Big Island summits. Mid level southwesterly winds will also strengthen east of the upper trough axis, and this will significantly increase Haleakala and Big Island summit winds. Thus, there is an increasing chance for both a Wind Advisory and Winter Weather Advisory for Mauna Kea and Mauna Loa’s summits Tuesday and Wednesday.

Fire weather:  Recent island wide rain and more overcast skies, along with relatively higher minimum afternoon humidities under light winds, will assist in maintaining a lower fire weather threat. There is a moderately high chance for a return to a wet weather pattern from Monday night onward. The inversion heights range from 6,000 to 8,000 feet.

Hawaii’s Marine Environment: Trade wind speeds will decrease and veer from a more E to SE direction from Monday to Tuesday, as the high pressure ridge north of the Hawaiian Islands weakens and drifts E in response to a surface trough over the islands, and an approaching cold front far NW of the state. Additionally, the cold front may advance into the offshore waters by Tuesday afternoon, bringing locally strong ENE winds behind it before the front diminishes over the NW coastal waters Wednesday.

Expect Small Craft Advisories to be issued for most of the Hawaiian coastal waters from Wednesday into Friday due to a combination of strengthening winds and rising seas. Isolated thunderstorms are possible over the Hawaiian waters through much of this week.

Expect multiple overlapping NW swells this week. This will keep surf heights boosted along exposed N and W facing shores. The challenge with this pattern will be in tracking the multiple swell energies from similar directions and similar periods. Wave height model guidance has trended towards combining these different swells for the Monday through Friday time period.

Surf along N facing shores remains small as a small medium period NW (310-320 degree) swell slowly declines into Monday. The next moderate, medium to long period NNW (320-340 degree) swell will then arrive late Tuesday, peaking Wednesday near High Surf Advisory thresholds along exposed N and W facing shores, then declining through the end of the week.

Another overlapping small, medium period NNE (010-020 degree) swell arrives from Thursday into Friday. Then another small, long period NW (320-330 degree) swell arrives in Hawaiian waters by Thursday night, peaking late Friday, then slowly diminishing into next weekend.

Surf along E facing shores will decline into Monday, due to the weakening of the local and upstream trade winds. As the high pressure ridge moves east later this week, the combination of a long easterly fetch of 15 to 20 kt winds upstream of the islands from Tuesday through Thursday, along with strengthening local winds along the cold front, will produce moderate and choppy surf along E shores. For S shores, periods of tiny background south swell energy will linger.

Interesting:  UK Prawn Farms Could Spark Sustainable Seafood Revolution

Farming king prawns indoors in tanks on UK farmland could create a thriving, sustainable seafood industry, researchers say.

King prawns are one of the “big five” sea foods eaten in the UK – but the vast majority of this tropical species is imported, and often comes from environmentally damaging sources.

Researchers from the UK Sustainable King Prawn Project (UKSKPP) say there is a “better way”: cost-effective and environmentally sound king prawn aquaculture (seafood farming) – creating new employment opportunities and making production of the freshest and tastiest seafood truly sustainable.
