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’s mostly clear early this morning here at my location, with a very chilly low temperature of 43.5 degrees, and the relative humidity is 71%.

 

Weather Wit of the day:  A man was interviewed for a job with the National Weather Service. A few days later he received a reply. “Your answers to our questions were vague, misleading and indecisive…you’re hired.”

Hawaii’s Broad Brush Weather Overview…as of 905am Wednesday: High pressure far to the north of the state will maintain moderate to breezy trade winds through Thursday, with the trades then easing Friday and Saturday, as a cold front approaches from the west. Fairly dry conditions will prevail, with light trade wind showers limited primarily to windward and mountain areas. A weakening cold front may bring an increase in rain chances Sunday and Monday, as it moves into the western islands. A more typical trade wind pattern then looks to return Tuesday into the middle of next week.

Hawaii’s Weather Details…as of 3am Wednesday: A 1030 millibar high is centered about 1500 miles north, and is generating moderate to locally breezy northeasterly trade winds across the island chain. Infrared satellite imagery shows partly to mostly cloudy conditions, with cloud coverage the greatest in windward and mountain areas. Radar imagery shows scattered to numerous showers affecting windward slopes and coasts, particularly across the eastern islands. Drier conditions are in place in leeward areas, with a few showers spilling over from time to time.

High pressure will hold in place to the distant north, maintaining moderate to locally breezy trade winds across the island chain through Thursday. Showers will favor windward and mountain areas, with a stray shower reaching leeward communities from time to time. Overall there should be a decrease in shower coverage and leeward penetration of showers each day, as building low to mid-level ridging helps to lower inversion heights across the state.

A weakening cold front will approach the islands from the west Friday and Saturday, easing the trades and shifting boundary layer winds around to the east-southeast. The deeper moisture associated with the front will remain to the west of the islands during this time frame, while inversion heights remain suppressed due to low to mid-level ridging over the state. As a result, rather dry conditions will persist.

The GFS and ECMWF models and AI versions are split on the handling of the pattern evolution Sunday into early next week. Roughly half support keeping deep moisture west of the state, while the other half indicate the deeper moisture moving into at least the western islands. Thus, the current forecast shows a slight increase in rain chances over the western islands Sunday and Monday, with a transition back to a trade wind pattern Tuesday through the middle of next week.

Hawaii’s Marine Environment…as of 3am Wednesday: Strong high pressure far north of the islands will maintain fresh to strong trade winds into Thursday. A Small Craft Advisory (SCA) has been extended for all waters due to a combination of these winds and elevated seas from a declining north-northeast swell, and the SCA has been pushed through Thursday for portions of the waters around Big Island and Maui County, where higher winds are typically encountered. Winds will ease over all waters and will gradually veer southeasterly around Kauai and Oahu Thursday night and Friday, as a surface ridge is displaced toward the islands by an advancing cold front. The SCA will likely be dropped at that time. The front will stall and degrade into a trough over the weekend, possibly bringing increased chances for heavy showers by Sunday.

A large north-northeast (010-030 deg) swell will gradually decline during the next few days, but will maintain elevated surf today. Marine Weather Statement continues for moderate to heavy surges in north facing harbors, mainly in Hilo and Kahului. Surf should fall below advisory levels by evening and continue a gradual decline through Friday. As east shore surf continues to decline this weekend, a small northwest swell will arrive. This swell will linger into early next week.

Surf along south facing shores will remain tiny through the week.

Interesting:  A Solution That Could Reduce Aviation Emissions by up to 30 Percent

In the future, regional flights such as Trondheim-Oslo could become much more environmentally friendly with the help of a hybrid aircraft engine. This type of engine combines an electric motor and a combustion engine to drive a propeller. The innovation should be able to reduce CO2 emissions by up to 30 percent.

“The principle that causes emissions to decrease is the same as for hybrid cars – that is, a combination of both fuel and electricity,” says SINTEF researcher Torstein Grav Aakre.

Aviation accounts for about four percent of the EU’s total climate emissions. This solution has the potential to reduce emissions by as much as one percent throughout the EU, according to the researcher.
