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

It’s mostly clear here in Maui County early this morning with just a few low clouds, with a chilly low temperature of 48.5 degrees at my place, with the relative humidity 65 percent.

Hawaii’s Broad Brush Weather Overview: Trades are expected to gradually weaken and remain light, prompting a land-sea breeze regime in response. Shower activity will be minimal, with only a few isolated showers. By the end of the week, a weak front will advance toward the state, but stall and dissipate over the western islands. Another potentially stronger cold front moves toward the Hawaiian Islands, and may bring enhanced shower activity to much of the state early next week.

Hawaii’s Weather Details: A broad area of high pressure currently positioned northeast of the islands will continue to migrate eastward toward the mainland. As a result, trades will weaken gradually today, and remain light through the remainder of the forecast period. With decreasing winds, a land- sea breeze pattern will result, supporting a few isolated showers across leeward and interior areas of most islands.

Overall rainfall amounts will remain minimal for the most part. In addition, latest observations from mid-level water vapor imagery indicates an area of drier air will move into the vicinity of the islands from the east, increasing the overall stability across the state, and further limit shower activity along windward areas.

Latest model guidance continues to showcase a shallow, weak frontal boundary advancing from northwest to southeast during the day on Friday, before stalling across the western half of the island chain. This feature may bring a modest increase in shower activity to Kauai on Friday, possibly extending into Oahu early during the weekend, due to lingering moisture from the latest event from earlier this week.

Elsewhere across the island chain will remain generally dry, aside from any isolated showers associated with the ongoing land-sea breeze regime. By the middle of the upcoming weekend, the aforementioned cold front is expected to dissipate, along with any remaining associated moisture.

Model guidance hints at another, potentially stronger frontal system early next week, in response to a mid-level trough just north of the islands. Both GFS and ECMWF models depict precipitable water values on the order of two to three standard deviations above climatological average associated with this feature. However, confidence remains low at this time regarding the timing, strength, and overall evolution of this system, due to considerable model uncertainty at this time.

Hawaii’s Marine Environment: Moderate to locally fresh east-southeast winds will prevail across the coastal waters as a ridge builds north of the region. A Small Craft Advisory (SCA) remains in effect for the typically windy waters of Maui County and the Big Island, though winds are expected to fall below SCA criteria across all waters soon. A front approaching the state from the northwest will further weaken the winds to light to moderate speeds on Thursday as they shift more southerly.

This frontal boundary will weaken as it enters the coastal waters Friday, then dissipate near the central islands by Saturday, with light to gentle winds expected. Another front will approach the state from the northwest on Sunday, then move down the island chain early next week.

A small, long period, northwest (310 degree) swell will build, peak through tonight, then slowly decline through Friday. Forerunners for the next significant large, long period north-northwest swell (330 degree) are expected to arrive Friday night and peak Saturday. This swell will likely produce warning level surf along exposed north and west facing shores. Another, large to extra large, north-northwest swell may fill in early next week, with surf heights peaking well into warning levels.

Surf along east facing shores has fallen below advisory levels and will continue to sharply decline over the next couple of days, as a north-northeast swell fades and easterly wind swell decreases.

Interesting:  Atmospheric River Research Flights Go Global

The UC San Diego-led program joins forces with research programs across the world to improve forecasts of extreme weather events.

Atmospheric rivers may be associated with wet winter storms on the West Coast of North America, but these ribbons of water vapor in the sky are a global phenomenon. They can end droughts or destroy homes with dangerous flooding, and they are projected to become more intense and destructive. Now, a new international effort will study and forecast these storms on a global scale.

Starting this year, the Atmospheric River Reconnaissance program (AR Recon), led by the Center for Western Weather and Water Extremes (CW3E) at UC San Diego’s Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration (NOAA), will coordinate flights to study atmospheric rivers across both the Pacific and Atlantic oceans. This expansion of AR Recon, which has studied atmospheric rivers using specially outfitted aircraft over the Pacific Ocean since 2016, is called the Global Atmospheric River and Reconnaissance Program (GARRP). This global program hopes to transform forecasts of extreme weather events and extend reliable predictions beyond the current one-week limit.
