~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Tuesday comments: I’m home here in upper Kula, Maui, Hawaii

Good day everyone, I hope you have a great Tuesday wherever you happen to be spending it.

511am, it’s a clear this morning here in Kula, with a low temperature of 51 degrees at my place.

835am, just back from my first walk of the day, the steepest of the three that I typically do each day. It’s yet another gorgeous day here in Maui County, with the leeward sides clear and sunny, while there’s a few clouds zipping along in the easterly trade wind flow…on the windward sides.

Noon, partly to mostly cloudy upcountry areas and along the windward sides, while sunshine continues to beam down along our coastal beaches.

 

Hawaii’s Broad Brush Weather Overview:  Trade winds will continue to weaken tonight through Thursday as a trough approaches the state. An unusually strong upper level low for this time of year will produce an unstable weather pattern late Thursday through around Saturday. Even though a wide spread heavy rain event is currently not expected, showers that do develop will bring the threat of flash flooding and isolated thunderstorms especially Friday afternoon through the evening.

Weather should gradually improve from west to east this weekend, but some unsettled weather will likely linger over the eastern half of the state Saturday.

Hawaii’s Weather Details:  In the short term, the trade winds will continue to weaken further into Wednesday, with sea breezes expected over leeward areas by Wednesday afternoon. This will allow for scattered afternoon showers to develop Wednesday over interior and leeward areas.

On the summits of the Big Island, wind observations continue to show wind gusts over 70 mph, thus the High Wind Warning has been extended. Winds should taper off by Wednesday but still may remain breezy at the summits throughout the day.

Starting Thursday, the atmosphere will begin to change as an upper level low approaches the state. The surface winds will likely weaken further, as a surface trough begins to develop over the state. Temperatures aloft will begin to cool, which will bring instability over the state.

With the added instability, some low level moisture and sea breezes, showers should increase during the afternoon on Thursday over interior and mountain areas. Due to light winds in the lower half of the atmosphere, any showers that develop will be slow moving and will be capable of producing some downpours in the afternoon.

Although some locally heavy showers will be possible Thursday afternoon, the main concerning period will be Friday through Saturday. An unusually cold upper level low will approach the state Thursday night, and is expected to be over or very close to the state by Friday afternoon. Temperatures occurring on the ECMWF and GFS models,  show very unusual conditions for this time of year.

This will produce a very unstable weather pattern for Friday and will allow for any showers that do develop to become a heavy rain threat. Also, with temperatures that cold aloft, we will likely see isolated thunderstorms with some of the stronger storms capable of producing small hail.

At this time, it is too early to tell exactly where the heavier showers and thunderstorms will develop, and it will highly depend on the position of the upper level low. Latest GFS and ECMWF runs have the upper level low centered just north of Kauai Friday afternoon. This will cause the most favorable area for thunderstorms and heavy rain to be from Oahu eastward.

But if the upper level low was to shift slightly more west, the entire state could see the threat of heavy rain and isolated thunderstorms. Although the details are still uncertain, the main takeaway is that we are not expecting a widespread rain event. But, any showers that do develop Friday will be capable of producing intense rainfall rates. With the potential for intense rainfall rates and the slow movement of any showers or thunderstorms, a Flood Watch could be issued in the coming days.

For the weekend, there is still quite a bit of uncertainty on how quickly the upper level low will move through the state (from west to east), with the latest models trending slower. Although the models have trended slower, there is fairly good agreement with the upper level low being east of Kauai by Saturday.

The threat for flash flooding and isolated thunderstorms should decrease from west to east as the upper level low slowly progresses eastward. At this time, the eastern half of the state, should see the greatest chance for some unsettled weather this weekend.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map

Marine Environmental Details:  Fresh to strong trade winds will slowly ease through Wednesday, as a high well north-northeast of the islands moves off to the northeast. A Small Craft Advisory (SCA) remains in effect for the typically windy waters around the Big Island and Maui County, continues to look like it may be dropped by tonight, as winds ease to moderate to locally fresh.

A surface trough of low pressure will form north of the island chain Wednesday. As this weather feature drifts southward near or over the islands Thursday into Saturday, the trade winds could ease further, and chances for heavy showers will likely increase.

Near shore buoys are showing signs of fading energy, suggesting the current south swell is slowly beginning to fade into Wednesday. Forerunners from a larger and longer lived south-southwest swell will arrive Wednesday, and surf is expected rise near, or to, the High Surf Advisory level during the peak of the swell Thursday and Friday. This swell will gradually decline through the weekend.

A small northwest swell will peak, then decline Wednesday. Wind driven waves will gradually decline to around May average, then drop to below average for the rest of the week.

Interesting:  Chorus of Whale Song Signals Antarctic Blue Whales May Be Making a Comeback

A nearly two-decade study of whale songs recorded in the Southern Ocean suggests that blue whales, the largest creatures ever to have roamed the Earth, may be recovering in Antarctica after being hunted to the edge of extinction.

Commercial whaling reduced the number of Antarctic blue whales from around 125,000 in the early 1990s to a few thousand today. But bans on whaling have made it possible for the critically endangered creatures to begin to rebound.

Measuring up to 100 feet long and weighing up 200 tons, blue whales can grow to the size of a passenger airplane, and make even more of a ruckus. The loudest animal on the planet, a blue whale can sing at a volume upwards of 180 decibels — louder than a jet engine.
