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 Tuesday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good Tuesday wherever you happen to be spending it.

It’s clear, with a cool low temperature of 49 degrees according to my outside temperature sensor.

 

Hawaii’s Broad Brush Weather Overview:  A high pressure system passing north of the Hawaiian Islands will keep moderate to breezy trade winds in the forecast today. Winds will veer from the east to southeast direction and weaken into light to moderate levels Wednesday through Friday. A shallow cold front and upper level disturbance are forecast to move into the islands this weekend. Expect another round of moderate to breezy trade winds as a high builds in behind the dissipating front, enhancing trade wind showers over the typical windward and mountain areas into early next week.

Hawaii’s Weather Details:  The latest satellite imagery continues to show a long band of clouds associated with a dissipating shallow cold front stalled just north of the state. Moderate to breezy trade winds may bring some of these cloud bands and a few showers into the western islands of Kauai and Oahu later today. Local radar imagery shows only isolated light shower activity across the state.

Looking at the wind forecast for this week, we see a high pressure system located northeast of the state drifting eastward. This system will continue to produce moderate to breezy easterly trade winds over the islands through this afternoon. This high center will slowly drift into the East Pacific, away from the islands, as a cold front approaches the state from the northwest.

Wind speeds will decrease and shift directions out of the east to southeast direction from Wednesday through Friday. Lighter large scale winds will allow local scale onshore sea breezes to expand in coverage over each island during this time period. Another migratory high passing north of the state, along with a shallow cold front moving into and dissipating over the islands this weekend, will bring another round of moderate to breezy trade winds to the Hawaii region from Saturday into early next week.

Weather wise a stable ridge aloft will keep low temperature inversion heights in place in through Friday. Then the weather pattern shifts, as a dissipating cold front will potentially move into and dissipate over the western islands this weekend. An upper level trough moving in with this front will likely enhance trade wind showers on Saturday and Sunday.

Global models continue to suggest this trough will deepen into an upper level low and become stationary near the Hawaiian Islands sometime early next week. Forecast confidence on the precise location for this system is low at this time. If this upper level low position does in fact set up near the islands, then the lift from this upper level disturbance will inject instability into the low level cloud field upstream of the island chain, briefly enhancing trade wind shower activity. The highest shower coverage in this scenario would favor windward and mountain areas in the overnight to early morning time period.

Long range models continue to show various solutions for an upper level low to develop and hover near the islands early next week. The latest GFS and ECMWF model solutions keep the low center east of the Big Island. Still too early to include much confidence in the forecast details for early next week. However, there may be a brief window, next week Monday or Tuesday, where some ice and snow may develop over the Big Island summits of Mauna Kea and Mauna Loa.

Fire weather:  No critical fire weather conditions are expected for the next seven days. Mostly dry weather are forecast across the state with limited shower activity as the dry spell continues through Friday. Shower trends increase starting Friday night with trade wind showers.

Hawaii’s Marine Environment:  Fresh to strong easterly trades continue over the eastern half of the state. Winds have veered slightly out of the southeast over the western half of the state and eased to moderate to locally fresh. The Small Craft Advisory (SCA) has been scaled back to windward Oahu waters and waters east of Oahu, due to the combination of strong winds and lingering high seas. Winds and seas are expected to drop below SCA thresholds as winds continue to gradually ease and shift out of the southeasterly. Winds are expected to become light and variable for the western half of the state Wednesday night into Friday. East to southeast winds will persist over the eastern half of the state and become gentle to moderate Thursday into Friday.

The current northwest swell (310-330) continues to trend down at the offshore and near shore buoys. The High Surf Advisory (HSA) for north and west facing shores has been dropped, as the swell continues to trend down at the local buoys. The next large northwest swell (310 degrees) is expected to fill in late Wednesday night, peak Thursday before gradually trending down Friday into the weekend. This second swell is excepted to produce warning-level surf along north and west facing shores, albeit smaller than the event this past weekend. This large swell will also elevate seas to above SCA thresholds as the swell fills in Wednesday night. Surf along east facing shores will briefly become rough and choppy as trade wind swell has picked up. A downward trend is expected during the second half of the week as winds weaken locally and upstream.

Interesting:  Study Finds Fluoride in Water Does Not Affect Brain Development

A University of Queensland study has found no link between exposure to water fluoridation as a young child and negative cognitive development.

Professor Loc Do from UQ’s School of Dentistry said the IQ scores of 357 people who had participated in the 2012–2014 National Child Oral Health Study were assessed by registered psychologists to see if their exposure to fluoride as a young child impacted their brain development.

With the participants now aged 16 to 26 years old, we found those who’d consistently been drinking fluoridated water had an IQ score 1.07 points higher on average than those with no exposure,” Professor Do said.
