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’s Broad Brush Weather Overview: A weakening cold front dissipates over the Big Island today. Expect much drier and cooler conditions for the state except for the Big Island, where remnants of the front will linger. Winds will veer southerly tonight and Wednesday, as the next cold front approaches from the northwest.

Expect breezy to locally windy south-southwesterly kona winds Wednesday. The next cold front is forecast to quickly slide down the island chain Wednesday night into Thursday and bring a line of moderate to locally heavy rainfall with it. The week should end cool and fairly dry with trades re-established.

Hawaii’s Weather Details: Latest satellite and radar imagery show the main frontal band dissipating over the Big Island. Peak rainfall totals from the frontal passage so far range from over 1.0 inch of rainfall from North Kohala to North Hilo, to 0.10 inches of an inches over the South Kohala and North Kona districts. Elsewhere, post frontal subsidence aloft made for a dry and cool evening. Dewpoints range from low 50’s to low 60’s across the state.

Winds have also relaxed to light to moderate breezy northerly. Expect mostly dry and sunny conditions today, as dry air aloft settles in and winds veer to a northeasterly direction. Parts of the Big Island and Maui will likely see clouds and showers linger through the day, due to remnant moisture around the Big Island, that will keep scattered light showers around for windward areas, as trades redevelop and for upslope Kona as the afternoon sea breezes develop.

Winds will veer southerly tonight as the next cold front approaches the islands from the northwest. Winds speeds will gradually strengthen to breezy to windy by mid-day Wednesday out of the south-southwest. Wind speeds may meet or exceed wind advisory criteria along ridge tops and areas downslope of elevated terrain in a predominate southwesterly kona flow during this time. This is so far the most concerning hazard with the next system, where winds could be strong enough to uproot trees in saturated soils especially downslope of ridges. Winds may also meet or exceed advisory levels for the summits of the Big Island.

Both the GFS and ECMWF models show moisture lifting northward over the western half of the state, ahead of the front, which will be conducive for pockets of prefrontal showers to develop within this flow. For the eastern half of the state, dry conditions prevail tonight into Wednesday.

The main rain band associated with the next front will quickly move through Kauai beginning late afternoon Wednesday and Oahu Wednesday evening. The rain band will then sweep across Maui County early Thursday morning before pushing through the Big Island Thursday. Latest guidance depicts this system to be similar, but more robust, than the one experienced yesterday, with moderate to locally heavy rain embedded within the rain band. Thunderstorms appear to remain northeast of the coastal waters at this time. The threat of flash flooding remains limited due to how quickly this front will move through the state.

Breezy northerly winds will immediately fill in behind the front and once again bring noticeably drier and cooler weather. These northerly winds will shift easterly over the weekend, as a surface high quickly passes northeast of the state. Upper level ridging will keep mostly dry and stable trade wind weather through the weekend. In the extended forecast another potentially robust front, will move over the state early next week, however there is still some significant difference in the timing and strengthen between the GFS and ECMWF models…stay tuned.

Hawaii’s Marine Environment: The forward motion of a diminishing cold front has stalled near the Big Island. This front will fade into a trough and then drift westward across the islands, ahead of the next approaching cold front. This next strong cold front will sweep from west to east through the western islands on Wednesday morning, and once again stalling near the Big Island by Thursday afternoon.

A passing high pressure system far north of the islands will bring back easterly trade winds across Hawaiian Waters from Friday through Sunday. Winds weaken and veer from a more southeasterly direction over northwestern waters by next week Monday, as another cold front approaches the islands from the northwest.

The current extra large, long to medium period northwest (310-330 degree) swell will continue to produce warning level surf along exposed north and west facing shores. A High Surf Warning (HSW) remains in effect for these shorelines, and a High Surf Advisory (HSA) remains in effect for west facing shores of the Big Island. The northwest swell energy will fall below warning thresholds tonight, and the HSW will transition to a HSA for the same north and west facing shores lasting through Wednesday. A Small Craft Advisory remains in effect for most coastal waters exposed to the large northwest swell and some waters exposed to stronger winds.

Another extra large, long period northwest (310-330 degree) swell will build into the region by Thursday, likely producing another round of warning level surf along exposed north and west facing shores lasting through Friday, and lingering near advisory levels Saturday, before another reinforcing northwest swell briefly boosts surf heights back above warning levels on Sunday and Sunday night.

Surf along east facing shores will remain small through most of this week, due shifting wind directions from the passing fronts, while no significant swells are expected to impact the state from the south.

Interesting:  What Past Global Warming Reveals About Future Rainfall

“Proxies” in geologic record show rainfall was more intense, but less regular during the Paleogene.

To understand how global warming could influence future climate, scientists look to the Paleogene Period that began 66 million years ago, covering a time when Earth’s atmospheric carbon dioxide levels were two to four times higher than they are today.

New research by the University of Utah and the Colorado School of Mines reconstructs how rainfall responded to extreme warming during this period using “proxies,” or clues left in the geological record in the form of plant fossils, soil chemistry and river deposits. The results challenge the commonly held view that wet places get wetter when the climate warms and drier places become drier, according to co-author Thomas Reichler, professor of atmospheric sciences at the U.

“There are good reasons, physical reasons for that assumption. But now our study was a little bit surprising in the sense that even mid-latitudes regions tended to become drier,” Reichler said. “It has to do with the variability and the distribution of precipitation over time. If there are relatively long dry spells and then in between very wet periods—as in a strongly monsoonal climate—conditions are unfavorable for many types of vegetation.”
