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

It’s cloudy here in Marin County, with a low temperature of 51.5 degrees in Linda’s backyard.

The sun has finally appeared again here, after being hidden by cloudy skies for three days straight!

 

Hawaii’s Broad Brush Weather Overview:  Light winds and mostly dry weather will prevail, but a weak front moving over the area will bring a chance of showers Sunday afternoon through Monday, mainly to windward portions of Kauai and Oahu. A brief period of moderate trade winds is possible around the middle of the week, with winds potentially diminishing by the end of the week.

Hawaii’s Weather Details:  Light winds and mostly dry weather will prevail this coming week, with a couple of exceptions. A weak front moving over the islands from the north will bring a chance of showers Sunday afternoon through Monday, mainly to north and east facing slopes and coasts of Kauai and Oahu, with a return to mostly dry weather thereafter. Except for an increase in trade wind speeds around the middle of the week, a nearby surface ridge will keep winds on the lighter side.

After another 24 hours of light and variable winds and essentially zero rainfall, a relatively weak high building northwest of the area will push a weak front over the islands. This front will bring an increase in moisture that will likely fuel some light showers. The high and associated nearby ridge will support light north to northeast winds as the front gradually dissipates through Tuesday, with land and sea breezes in sheltered areas on land. High clouds streaming over the area from the west should shift south, diminishing over the next 24-48 hours.

Strengthening east-northeast trade winds may briefly reach moderate levels around mid-week, when the high moves to a position northeast of the islands. Although confidence is low, trade winds may diminish again by the end of the week, as a low passes by north of the islands. Limited (windward) to no (leeward) rainfall is expected after the cold front dissipates.

Fire weather:  An overall dry weather pattern is expected through Sunday into early next week over most islands. 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:  Weak high pressure will hold just north of Hawaiian offshore waters through most of this weekend. A weak front will move into the far western waters Sunday evening then dissipate over the center island chain by Tuesday afternoon. Winds are expected to remain light and variable through Tuesday. Light to moderate trade winds will return later in the week, when high pressure rebuilds to the north of the state.

The current, small NNE (360-020) swell impacting the Islands will peak. A second moderate pulse from the same source will fill in and provide reinforcement. Lastly, an overlapping NW swell (320 degrees) will build in and peak during the day Sunday. A Marine Weather Statement is in effect for harbor surges, particularly at Hilo and Kahului harbor, generated by the two more northerly swells. Surf along north and west facing beaches will build, approach High Surf Advisory (HSA) criteria on Sunday, then subside early next week.

Surf along east facing shores will be elevated into Sunday as the more northerly swells peak and wrap into eastern exposures.

Interesting:  A Hazy, Foggy Day in Italy’s Po Valley

The Po River Valley, one of Italy’s most densely populated regions, is home to over 16 million people. The valley is also one of the country’s foggiest and haziest regions.

In the fall and winter months, fog and low clouds routinely blanket the basin, often preceded by haze—a mixture of airborne particles, known as aerosols, emitted by vehicles, fires, industry, and other sources. The surrounding mountain ranges limit air circulation, helping fuel temperature inversions that trap air pollution near the surface.

The MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Terra satellite captured this image of morning fog on November 16, 2024. “It formed when a high-pressure system over central Europe led to calm and stable conditions in the valley, ideal for the formation of radiation fog,” said Eva Pauli, a research meteorologist at the Karlsruhe Institute of Technology in Germany.
