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 Wednesday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s clear to partly cloudy here in upper Kula early this morning, with my low temperature 55 degrees.

Mid-day, skies are clear to cloudy, with the clouds looking stable and not showery at the moment. Yesterday late in the afternoon they took on a more showery nature, we’ll see what comes this afternoon…hoping for a few more showers in my area.

 Weather Wit of the day:  Spring – When car thieves switch from sedans to convertibles

 

Hawaii’s Broad Brush Weather Overview:  Locally breezy trade winds will persist through early next week, as high pressure remains far north of the state. Somewhat active showers will continue across windward areas into the weekend. The gusty trades will carry brief showers over most leeward areas, while the leeward slopes of the Big Island experience spotty showers mainly in the afternoon and evenings.

Hawaii’s Weather Details:  A modestly active shower pattern continues within the locally breezy trade wind flow. Persistent robust high pressure centered far to the northwest, has the islands locked within a locally breezy and gusty trade wind flow, and broad upper-level troughing over the region, has weakened and elevated the inversion, supporting a field of shower-bearing cumulus over and 500 miles east of the state.

A loosely organized area of moisture within this cloud field has arrived, producing roughly one quarter to three quarters of an inch of rainfall over wetter windward locales. The gusty winds have periodically carried some rainfall over leeward areas from Kauai to west Maui, but accumulations were well below a tenth of an inch. The leeward slopes of the Big Island are transitioning toward a more summer-like pattern of spotty showers, some briefly heavy, during the mid-day through evening hours, followed by diminished rainfall overnight.

Breezy and somewhat wet trade winds will persist through at least Friday, as additional pockets of moisture move through and the weak uper-level trough keeps the inversion elevated. A ridge aloft will develop over the region during the weekend, bringing an increase in stability. Models are suggesting that a band of moisture drifting in from the northeast, could keep windward rainfall more active over windward Kauai and Oahu, but the increasingly stable conditions may limit leeward rainfall, even as the trades remain breezy and gusty. Typical trade wind weather looks to continue into early next week.

Hawaii’s Marine Environment:  Fresh to strong trades will persist through the weekend as a surface ridge remains north of the islands. A Small Craft Advisory will persist each day for the typical windier waters and channels around Maui County and the Big Island.

Surf along north and west-facing shores will remain up around average through Thursday due to a medium-period northwest swell that filled in Tuesday afternoon. This swell will gradually shift out of the north over the next couple of days.

Surf along south-facing shores will remain below average through Friday. A fresh long-period south- southwest swell is expected to arrive over the weekend, bringing an upward trend with above- average surf. Forerunners should begin filling in Friday, with the swell peaking late Saturday through Sunday. This swell has peaked slightly above guidance at the American Samoan buoy, which will translate to a peak locally late Saturday into Sunday.

Surf along east-facing shores will remain rough and choppy, with heights around average into the second half of the week. Heights could dip below average by the weekend due to a weakness forming in the ridge northeast of the area, leading to the upstream trades diminishing. A return to average levels is expected later this weekend and into early next week as the trades strengthen upstream.

Interesting:  After 17 Years Underground, Massive Cicada Brood to Swarm U.S.

After hiding underground for the last 17 years, billions of cicadas will take to the skies this summer, from Tennessee to Cape Cod.

These cicadas, known as Brood XIV, will cover more of the U.S. than any other 17-year brood. They are also the original brood from which all other 17-year broods branched off.

After surfacing in May and June, these cicadas will issue their noisy, chirping mating call for just a few short weeks before laying eggs and dying. Their offspring will remain dormant underground for another 17 years.
