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 mostly clear with a few clouds early this morning, with near calm winds, and a cold low temperature of 41.5 degrees at my place, and the relative humidity 65%.

1243pm, mostly sunny with just a few scattered clouds around here in Maui County, with very voggy air, and light winds…relative humidity 59%

520pm, mostly sunny here in Maui County, and most of the other islands to, with the Big Island being the one exception. The hazy skies remain in place here on Maui.

From NWS Honolulu Forecast Office:

Strong trade winds and heavy rain capable of producing flash flooding are likely increasingly Saturday through Monday.

  • Most locations will receive rain, possibly heavy at times, but showers will move quickly reducing the flash flooding threat. However, it appears that training heavy showers and isolated thunderstorms may impact Windward Haleakala on Maui and the Hamakua Coast on the Big Island. In this scenario, the threat for flash flooding would significantly increase.
  • Heavy rain is possible as early as Saturday but is most likely Sunday into Monday. Flash flooding appears to be most likely for Maui County and the Big Island, particularly windward.
  • Strong trade winds will develop along and behind the band of heaviest rainfall. Trades will strengthen Saturday through Sunday, potentially peaking around the High Wind Warning threshold (sustained 40+ mph and/or gusts to 58+ mph) by late Sunday through Monday. Wind of this magnitude is most likely for Kauai through Maui County, particularly over terrain, through valleys, and other local acceleration areas.

 

Hawaii’s Broad Brush Weather Overview:  Clouds will be on the increase the next couple of days, with scattered showers as winds come around to a southerly direction, directing higher moisture over the islands. The pattern will undergo a more windy and wet change this weekend, as a front travels across the islands from the west. The associated upper low will dig down west of the island chain through the week, and be the impetus to more frequent rain that may become locally heavy, strong winds and thunderstorms late Saturday through early next week.

Hawaii’s Weather Details: It was one of those somewhat rare beautiful, mainly clear sky days across the majority of the islands today. The lone exception was Big Island where warmth-of-the-day cloud build ups occurred along the slopes of Mauna Kea and Mauna Loa. Early day land breezes have swung around to sea breezes with the overall background flow veering east-southeast as surface ridging drifts overhead. Very comfortable humidity-wise as dew points range in the middle 50’s to lower 60’s.

This post-frontal air mass will begin to modify tomorrow, as moisture levels increase upon primarily the southerly flow. An approaching, slowing moving cold front from the west will reach the western waters Friday into Saturday. This boundary will produce ever-strenghtening southwest kona winds over Oahu and Kauai. This front will also be a vehicle for deepening boundary layer humidity, as downstream moisture begins to pool ahead of the front`s wind shift.

The associated mid to upper level trough is forecast to deepen west of the state over the weekend. Previous run-to-run consistency with the evolution of this trough into a broad cut-off low in its base west southwest of Niihau and Kauai by late weekend, has increased confidence that there will be more statewide active weather from late Saturday through at least Monday. Backing high pressure from the west will tighten the lower to middle level pressure gradient between northwesterlies north of the front, and weaker southeasterlies downstream of the front.

More rich moisture will be transported up just ahead of the frontal boundary, that will be positioned somewhere over Maui County and Big Island by early Sunday. At the same time, the trough to our west will deepen and cool mid to upper levels significantly. Decreasing stability as cooler air moves in, with high moisture content air pumping in from the south ahead of a stalled boundary on Sunday, signals high rainfall and increasing chances for thunderstorms, especially over the windward sides of Maui County and Big Island. The eastern end of the state could experience rounds of heavy, training rainfall, along with scattered thunderstorms that may induce periodic flooding.

A weekend flooding situation could transition into more of a wind threat as strong trades bear down on the state from late Sunday through mid next week, as building high pressure behind a weakened and northeast-exiting front creates a very tight gradient pressing down on Hawaii. Early week rain with strong northeast east winds shortly thereafter may be a recipe for more tree fall and vegetation damage that would likely result in widespread power outages.

Upper ridging expands in from the north-northeast by late next Wednesday. While model guidance maintains fresh to strong trades as the surface gradient remains very tight, back to a strong surface high as it parades across the Central Pacific, precipitation will be trending down during mid to late week. Not totally dry though in terms of shower activity, as showers ride in within the strong trade flow into next weekend.

Hawaii’s Marine Environment:  Moderate to fresh north to northeast breezes will briefly veer out of the east as high pressure builds over the state. The pressure gradient will become weak enough to support localized afternoon sea breezes for Kauai and Oahu. Moderate to locally fresh south to southwest kona winds are expected to return over the western end of the state during the second half of the week, as the next cold front draws closer. Guidance shows this next front moving into the area late Friday through Saturday, with strong- to near gale-force northeast winds filling in behind it late in the weekend through early next week. Ocean conditions will quickly respond and become rough due to a combination of winds and seas. In addition to the winds and seas, a wet pattern with locally heavy rainfall and potentially a few storms will accompany this front.

Surf along exposed north- and west-facing shores of the smaller islands will remain well above warning levels before gradually lowering to advisory levels by Thursday. Observations at the offshore buoys to the northwest reflect this trend and indicate the swell steadily easing overnight. Heights will dip below advisory levels for a brief period Thursday night into Friday, then return to warning levels for exposed coasts Friday night into Saturday, due to a fresh northwest swell arriving. For north facing shores of the Big Island, heights will remain around the advisory level, then drop below tonight.

Surf along east facing shores could quickly rise and become rough this weekend, with heights potentially nearing the warning level during the peak by Monday.

Interesting:  Greenland Ice Cap Vanished Just 7,000 Years Ago

The first study from GreenDrill—an ambitious project to recover rock samples buried thousands of feet beneath the Greenland Ice Sheet—finds that Greenland’s Prudhoe Dome ice cap had fully melted around 7,000 years ago, much more recently than previously thought. This research, co-led by Columbia University and the University at Buffalo, is intended to assess how sensitive Greenland’s ice is to climate change.

Published in Nature Geoscience, the findings suggest that the Prudhoe Dome, an ice dome in northwestern Greenland about 1,700 feet thick covering 965 square miles, is highly sensitive to the relatively mild temperatures of the Holocene, the interglacial period that began 11,000 years ago and continues today.

“The Holocene is a time known for climate stability, when humans first began developing farming practices and taking steps toward civilization,” says University at Buffalo’s Jason Briner, who co-leads the GreenDrill project. “If natural, mild climate change of that era melted Prudhoe Dome and kept it retreated for potentially thousands of years, it may only be a matter of time before it begins peeling back again from today’s human-induced climate change,”
