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 Thursday comments:  I’m here in Corte Madera, California, I hope you have a great Thursday wherever you happen to be spending it.

We had a cold front move over our area here in northern California last night, which dropped a decent amount of rain…the low temperature was 43 degrees here in Corte Madera.

It was a clear day with high clouds at times, a really nice day before more rain arrives later Friday into Saturday, which will be associated with the next cold front.

Hawaii’s Broad Brush Weather Overview:  Moderate to locally breezy trade winds will continue into Friday, with high pressure far to the north-northeast of the islands. Showers riding in on the trades will remain focused over the windward sides of the islands into the weekend. Trade winds will weaken this weekend as the high moves to the east, and fewer showers will be carried in. Another round of wet weather is expected next week.

Hawaii’s Weather Details:  Moderate to locally breezy trade winds continue due to the high pressure system to the far north-northeast. Showers will continue to be carried in on the trades, and will remain focused over the windward sides of the islands. Most of the clouds and showers extend east of the Big Island, so expect more showers at the southern end of the state into Friday.

Heading into the weekend, the high will begin to move to the east, resulting in the pressure gradient over the islands weakening. This will lead to a bit of a downward trend in the wind speeds, and could turn the winds a bit more east to east-southeasterly.

The GFS and ECMWF models continue to be in good agreement with the surface and upper level features heading into the weekend. The high moving to the east, and mid-level ridging helping to stabilize the environment over the islands a bit, leading to the downtrend in shower activity.

Beyond that there is still general agreement with the surface features in the global models, but vastly different handling of the mid and upper levels. These differences will be a factor in what ultimately pans out. There is general agreement that a cold front will approach from the northwest mid-week, but differences in timing and how far down the island chain the front goes.

Differences in the timing, placement and strength of the mid and upper levels will factor into the amount of rain, and the frequency of showers. This will also determine winter weather possibilities for the Big Island summits, and the possibility for thunderstorms. While the models suggest thunderstorms mid-week, the probabilities are low however.

The forecast from Monday shows the chance for snow on the Big Island summits started Wednesday night, and there seems to be sufficient agreements with deep layered moisture and cold temperatures aloft, to support such a solution. Additional refinements will likely be made as the event gets closer, and hopefully there is more agreement in the models.

Hawaii’s Marine Environment:  Expect fresh to strong trade winds to continue through Friday, then decrease into the gentle to fresh range this weekend, as the ridge north of the island chain weakens. The Small Craft Advisory was extended in time for the typical windier zones and waters around Maui and the Big Island through Friday afternoon.

A small north-northeast swell will lower into Friday. An upward trend is expected this weekend. Expect small forerunners to arrive by Friday afternoon from the north-northwest, then building over the weekend with peak swell heights arriving on Sunday. Surf heights could approach advisory levels for exposed north and west facing shores during the peak of the swell on Sunday, especially if the swell heights comes in higher than predicted.

Surf along east facing shores will remain rough through the week, due to the strong trades locally and upstream across the eastern Pacific. A downward trend is forecast for this weekend.

Surf along south-facing shores will remain small, with mainly a mix of southeast and background south swell energy.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:  There are no active tropical cyclones

>>> Southwestern Caribbean Sea:

A broad area of low pressure is likely to develop over the southwestern Caribbean Sea during the next day or so. Gradual development is possible thereafter, and a tropical depression could form over the weekend or early next week while the system drifts generally northward or northwestward over the central or western Caribbean Sea. Regardless of development, locally heavy rains are possible over portions of the adjacent land areas of the western Caribbean.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 7 days…medium…60 percent

>>> Northeastern Caribbean Sea and Greater Antilles:

A trough of low pressure near Puerto Rico is producing widespread cloudiness and showers over the Dominican Republic, Puerto Rico, the Virgin Islands, the northern Leeward Islands, and the adjacent waters of the Atlantic and the northeastern Caribbean. Slow development of this system is possible during the next 2-3 days as it moves west-northwestward near the Greater Antilles. After that time, this system is expected to be absorbed into the low pressure area over the Caribbean. Regardless of development, locally heavy rains are possible during the next several days from the northern Leeward Islands westward across Puerto Rico and Hispaniola to eastern Cuba and the southeastern Bahamas.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 7 days…low…10 percent

>>> North Atlantic:

A storm-force non-tropical low pressure area located about 500 miles west of the western Azores is producing limited shower activity. Some subtropical development is possible while the low moves generally eastward during the next few days.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 7 days…low…20 percent

Gulf of Mexico:  There are no active tropical cyclones

Northeastern Pacific:  There are no active tropical cyclones

 >>> Central East Pacific:

Invest 92E

Satellite-derived winds indicate that the area of low pressure located a little over 1200 miles southwest of the southern tip of the Baja California peninsula has become better defined this afternoon. However, shower and thunderstorm activity remains disorganized. Some further development of this system is possible during the next couple of days while the low moves slowly to the west-northwest. By late this weekend, environmental conditions are expected to become less conducive to development.

* Formation chance through 48 hours…medium…40 percent
* Formation chance through 7 days…medium…40 percent

>>> Southwest of Southwestern Mexico:

An area of low pressure could form well offshore of southwestern Mexico during the early to middle part of next week. Afterward, some slow development is possible while the system meanders or drifts generally eastward.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…low…30 percent

Interesting:  Using Weather Radar to Track Australia’s Migrating Birds

For the first time, scientists have used data from weather radar not to track storms, but to count birds as they travel across Australian skies.

The study, led by University of Queensland PhD candidate Xu Shi, used 16 years of radar weather data from the Bureau of Meteorology to monitor bird migration patterns from Tasmania to northern Queensland.

“We were very excited to discover millions of birds migrating in Australia each year, escaping cold southern winters by moving up the east coast,” Mr. Shi said.

“Birdwatchers have known for a long time that some Australian birds migrate, but never before have we been able to study the phenomenon so clearly.
