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 Aloha Friday comments:  I’m here in Corte Madera, California, visiting my good friend Linda.  I hope you have a good Friday wherever you happen to be spending it.

It’s cloudy here in Marin County with light showers, with a low temperature of 58.5 degrees in Linda’s backyard.

We have what’s called an Atmospheric River moving through northern California! It’s been off and on gusty with light to moderate rain falling over the last 48 hours!

Here in Marin County the rain is suppose to intensify today into Saturday morning, along with strong and gusty winds, in association with a cold front pushing through the area.

 

Hawaii’s Broad Brush Weather Overview:  Trade winds will weaken today and become light and variable during the weekend. The atmosphere will be stable and rather dry with minimal rainfall expected. A shallow and dissipating front move may across portions of the island chain Sunday night and Monday, bringing only modest showers and likely maintaining light winds. Light trades may return by the middle of next week.

Hawaii’s Weather Details:  A stable and rather dry trade wind flow will diminish through Saturday. Trades will continue to drop as a surface high, currently sitting north of Oahu, moves east and weakens. With trades on the decline, localized overnight land breezes and daytime sea breezes occurring today will become more prevalent on Saturday.

A weak mid-level ridge will maintain stability, and a swath of rather dry low-level air around the area will keep precipitable water below an inch. As a result, expect minimal windward rainfall, and leeward sea breezes will produce afternoon clouds over terrain, but little, if any, shower activity is expected.

Dry air will help to push overnight low temperatures into winter-like range of the mid to even lower 60’s in some locations. In addition, a developing weak jet stream aloft will generate increased thin high clouds today and Saturday.

Sunday into early next week, the overall pattern favors light disrupted trade winds and a weak front passing over the northern end of the island chain. For Sunday, trades will become light and variable or northerly as a weak front approaches. A dry land and sea breeze pattern is likely, though a small pocket of moisture could produce some active showers on the Big Island.

Timing in the GFS and ECMWF models have come into better agreement, showing a weak front bringing modest showers to windward and northern slopes of Kauai Sunday night, and to Oahu and possibly Molokai on Monday.

Details become elusive by Tuesday due to model differences. These same models are showing the potential for another weak front passing near or over the state, followed by an upper-level ridge moving westward into the region around Wednesday. They go on to show the potential for significant rainfall is low, with light northerly winds becoming trade winds around Wednesday.

Fire weather:  An overall dry weather pattern is expected through at least Sunday over most islands. With dry air moving overhead, relative humidity values will have the potential to drop below the critical 45% threshold during the late morning and afternoon hours. However, lighter winds will mitigate fire weather concerns.

Hawaii’s Marine Environment:  A weak ridge of high pressure north of the state is producing light to locally fresh winds. This ridge will gradually weaken and shift south, and over the weekend as a weak front approaches from the northwest. In response, winds will gradually become light and variable Saturday into early next week. A weak transient high will build north of the state by the middle of next week, allowing gentle to fresh northeasterly trade winds to briefly return.

A small north-northeast swell (010-030 degrees) is filling at near shore buoys. This should produce some small surf along north facing shores. Another more moderate pulse from the same source is expected Saturday along with a similar size overlapping northwest swell (320 degrees). These combined swells will elevate surf along north and west facing shores just shy of High Surf Advisory (HSA) criteria on Sunday, before subsiding early next week.

Surf along east facing shores will see some energy from the northeasterly swell wrap into the weekend. Surf along east facing shores will become more elevated over the weekend, especially Saturday into Sunday, as the swell peaks and shifts more easterly, wrapping into exposed areas.

Interesting:  Why Manatees are Likely Not Florida Native

With a county named after them, license plates with their depictions and parks promoted as the best places to view the gentle herbivores, known as sea cows, manatees are undoubtedly a part of Florida culture.

But they might also be relatively new residents in the Sunshine State.

The evidence backing this theory is compiled in a research paper written by Thomas Pluckhahn, a professor of anthropology at the University of South Florida, and David Thulman, an archaeology professor at George Washington University.

According to their paper published in PLOS ONE, for centuries, manatees might have occasionally swum in Florida waters, but possibly more so as tourists than residents, staying for a short visit before returning to their Caribbean homes, such as Cuba.
