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 Sunday comments:  I’m here in Corte Madera (Marin County, CA) at my friend Linda’s place

It’s clear early this morning…with a very chilly low temperature of 36 degrees.

I played Pickleball in Mill Valley this morning, and as usual, it was very fun.

The day here in Marin County remained quite cool, with cloudy skies giving way to partly cloudy skies, that is until around sunset when it became cloudy again.

904pm here in northern CA, and the temperature has dropped to 44.4 degrees.

Hawaii’s Broad Brush Weather Overview: Light to moderate trade winds will continue through the next few days, followed by light east to southeasterly winds mid-week, and increasing southeasterly winds Friday into next weekend. Shower chances will trend down through the first half of the week as a cold front passes by well north of the islands. By next weekend, an approaching cold front could result in southerly flow and increased showers, particularly over the western end of the state.

Hawaii’s Weather Details: Light to moderate trade winds are prevailing across the island chain as a weakened surface high remains centered well northeast of the state. Latest satellite and radar imagery shows only a few light showers favoring windward and mountain locations, in addition to afternoon cloud buildups and light showers along the Kona slopes of the Big Island.

As a trough aloft moves farther east away from the islands tonight, ridging will build back into the region, increasing stability. Additionally, even drier air can be seen on Precipitable Water imagery just east of the islands, and this drier air is expected to move overhead tonight into Monday.

The increasing stability and drier air will result in an overall downward trend in windward and mountain showers through the next couple of days. Light to moderate trade winds will continue through mid-week, as a couple of cold fronts move across the North Pacific, well north of the islands, and keep the surface high to our northeast in a weakened state throughout this time.

On Wednesday, another front will approach the islands but pass north of the state. As this feature approaches, the surface ridge to our northeast will be displaced southward, with the ridge axis extending directly over the Hawaiian Islands. Expect lighter east to southeasterly winds as the front approaches from the northwest.

Not much change is expected regarding shower chances throughout this time, however, as the ridge over the islands will maintain fairly stable conditions, with subsidence temperature inversion heights hovering around 6,000 to 7,000 feet. As winds decrease mid-week, daytime sea breezes and overnight land breezes are likely to develop over sheltered areas.

Model guidance continues to indicate that a much more robust surface low will move across the North Pacific next weekend, and its trailing cold front could impact at least portions of the Hawaiian Islands Saturday into Sunday. As this front approaches the western islands, southerly flow has the potential to draw deeper tropical moisture northward, producing humid weather and increasing showers trends. Latest guidance depicts the approaching cold front stalling and then dissipating near Kauai late next weekend.

Fire weather:  Critical fire weather conditions are not expected throughout the next few days. Relative humidity levels are expected to decrease Monday as stable, drier air settles over the state. However, wind speeds are expected to stay below critical thresholds. Relative humidity values will rebound throughout the rest of the week as winds remain light to moderate.

Hawaii’s Marine Environment: An area of surface high pressure far northeast of the state will allow for gentle to locally fresh easterly trades to prevail through Thursday. Expect a brief increase of southeasterly winds on Friday, followed by weak flow next weekend, as a frontal system passes by north of the islands. Winds should remain below Small Craft Advisory (SCA) criteria through the period. However, combined high seas are forecast for exposed waters Wednesday into Thursday as a large Northwest swell arrives.

The currently moderate, long period, northwest swell (310-320) has peaked. This swell is still running a foot or two above guidance. Surf will continue to slowly decline. Monday into Tuesday, north shore surf will drop below the seasonal average. Another northwest swell, potentially larger, is expected to arrive Wednesday and peak into Thanksgiving day. If current guidance holds, another High Surf Advisory will be warranted. Surf could possibly reach warning levels if the swell comes in above guidance, as the last several have. This swell will decline Friday into next weekend.

As trade winds weaken over the next couple of days, surf along east facing shores will decline and will be well below seasonal average through much the week. South shore surf will be tiny through much of the week.

Interesting: Monsoon Storms Will Bring Heavier Rains but Become Weaker

Climate change will make monsoon storms in South Asia wetter and weaker, with more storms pushing further inland across India.

Scientists from the University of Reading used 13 climate models to understand how warming temperatures will affect monsoon low-pressure systems. These storms deliver more than half of all monsoon rainfall and nearly all extreme rainfall events across South Asia.

The research, published in the Journal of Climate, found that storms will become about 10% weaker by the time global temperatures rise 3°C above pre-industrial levels. Despite becoming weaker, each storm will produce more rain – up to 28% more for the strongest storms. By the time temperatures reach 2°C of warming, average rainfall from each storm will increase by roughly 10%.

Dr Kieran Hunt from the University of Reading and lead author, said: “How can weaker storms produce more rain? It sounds wrong, but the answer partly lies in changes to moisture patterns. Warming temperatures increase the difference in moisture levels between northern and southern India. Winds ahead of storms push this extra moisture into the rainfall zone, making storms wetter even though their winds are slower.”
