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 Thursday comments:  I’m here at home in upper Kula, Maui

It’s mostly cloudy early this morning, with a low temperature of 51 degrees at my place.

230pm, radar shows some heavy showers falling over and around Maui, although here in upper Kula, at least over my particular area, it remains cloudy but dry.

Hawaii’s Broad Brush Weather Overview:  A stalled frontal boundary near Maui will remain over the area through Friday, and bring enhanced shower activity to mainly Maui County, and to a lesser extent windward portions of the Big Island. Unsettled weather resumes this weekend, as moisture moves over the islands from the south, out ahead of the next approaching frontal system. The front is forecast to pass down the island chain Sunday night into Monday, and bring with it a band of steady rain. Trades should return by Tuesday, as a surface high passes north of the islands.

Hawaii’s Weather Details:  Satellite loop shows a complex of lows spinning in the north central Pacific, with a shield of mid and upper level clouds streaming over Hawaii from the southwest, associated with an upper level trough. Down at the surface, a shallow north to south oriented surface boundary remains over Maui County. Some pulses of energy rotating around the parent upper trough allowed for showers to reignite, with pockets of heavier showers forming along the mountainous region of eastern Molokai and lower slopes of Haleakala on Maui. RADAR estimated rain rates generally topped out in the half inch to inch an hour range. Elsewhere mid and high clouds dominated, but with little in the way of precipitation.

Tonight, the surface boundary may wobble slightly eastward, then retrograde back towards the central islands and dissipate on Friday. Thus, most shower activity over the next 12 to 18 hours should stay closer to the boundary, along windward and mountain portions of Maui, and to a lesser extend the Big Island. Winds will veer easterly by Friday afternoon, as a transient surface high quickly passes to the north. This will allow for a brief return of scattered showers along mainly windward locations of the island chain.

On Saturday, another trough deepens over our area, as the next winter cold front begins its approach. In response, light to locally moderate surface winds will veer southeasterly on Saturday, becoming southwesterly kona’s by Sunday. Both the GFS and ECMWF models generate scattered shower activity this weekend, skewed towards the western half of the state, as deeper moisture gets drawn up in this southerly flow.

Sunday night into Monday, long range models push the tail-end of cold front down the island chain from the northwest. A moderate to locally heavy band of rain may accompany this front, though best lift and moisture parameters remain well north of Hawaii. It is still too early to determine to what extend a flooding threat exists, but appears minimal if current trends hold.

The ECMWF model is a few hours earlier than the GFS model on the frontal passage, but both agree on Monday morning to early afternoon to be the most likely time. Chilly post-frontal winds will be quick to veer northerly, then northeasterly as a surface high passes north of the region, allowing for the brief return of trades.

Hawaii’s Marine Environment: Light to moderate northeast winds will persist into Friday across most waters, as a stalled frontal boundary gradually diminishes over the eastern end of the state, and high pressure builds to the north. The exception will be over the Big Island waters east of the boundary, where light east to southeast winds will prevail. Guidance indicates a progressive pattern continuing into the weekend, with a front approaching and moving through the area Sunday into Monday, followed by another front approaching by mid-week. The weekend front could bring locally heavy showers to portions of the marine area, along with a period of moderate to locally fresh southwest kona winds.

Surf along exposed north- and west-facing shores will remain near advisory levels into Friday, as overlapping west-northwest and north-northwest swells move through. Offshore buoy observations reflect this mixed swell regime, with north-northwest energy in the 1012 second range and west-northwest energy holding in the 13-15 second bands. Guidance shows these swells easing late Friday into the weekend, with a small, long-period northwest swell arriving late Saturday.

Surf along east-facing shores will remain small into next week, due to the lack of persistent trade winds locally and upstream.

Interesting:  Measuring Movement Creates New Way to Map Indoor Air Pollution

University of Birmingham scientists have developed a new way of measuring and analyzing indoor air pollution that – in initial trials – has established a clear link between office occupancy, physical activity, and air quality.

Using radar-powered movement detectors and low-cost pollution sensors, researchers equipped office space in central Birmingham to monitor the number of people present and measure the kinetic energy they generated as they went about their work.

One of the most important, yet insufficiently studied, sources of indoor air pollution is particulate matter (PM) that is made airborne through occupants’ movements. Particulate matter trapped within carpeting, furniture, office equipment, and people’s clothes and shoes becomes airborne in indoor environments through human activity.
