77 Lihue, Kauai
82 Honolulu, Oahu
75 Molokai
87 Kahului, Maui
85 Kona, Hawaii
84 Hilo, Hawaii
Air Temperatures ranged between these warmest and coolest spots near sea level – and on the highest mountain tops around the state…as of 510am Thursday morning:
Kaneohe, Oahu – 75
Molokai airport – 64
Haleakala Summit – 41 (near 10,000 feet on Maui)
Mauna Kea Summit – 27 (13,000+ feet on the Big Island)
Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800
foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight
hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too…depending upon weather conditions. Here’s the Haleakala Crater webcam on Maui – if it’s working.
Tropical Cyclone activity in the eastern and central Pacific – Here’s the latest weather information coming out of the National Hurricane Center, covering the eastern north Pacific. You can find the latest tropical cyclone information for the central north Pacific (where Hawaii is located) by clicking on this link to the Central Pacific Hurricane Center. A satellite image, which shows the entire ocean area between Hawaii and the Mexican coast…can be found here. The 2012 hurricane season is over in the eastern and central Pacific…resuming on May 15th and June 1st 2013.

~~~ Hawaii Weather Narrative ~~~
Trade winds returning Thursday into Friday…then slipping again this weekend. Here’s a weather chart showing a near 1034 millibar high pressure system, located far to the northeast of the islands. This high pressure cell has an associated ridge of high pressure extending southwest from its center, to the northeast of Maui and the Big Island. At the same time, a dissipating trough of low pressure is over Maui County as well. Our local winds continue to come in from variable directions…as this late season slowly slips away. We’ll still see a bit of vog in some areas, although it should be blown away by Thursday.
Satellite imagery shows scattered clouds over parts of the island chain…with residual towering cumulus well offshore to the northeast and southwest. There’s an area of high cirrus clouds, now having moved well to the south of the state. Here’s the looping radar image, showing showers, now moving over Oahu in the slowly returning trade wind flow. The leftover convective weather pattern prompted clouds, and a few showers again over the other islands this afternoon…although this should end soon. Precipitation will be most notable over Oahu, as what’s left of the old front/trough remains in place there for a while longer.
The computer models are showing the trade winds backing off again this weekend, into early next week. The GFS model shows another cold front getting close to Kauai by this Sunday into next Monday. The models go on to show this frontal boundary stalling before arriving into the islands…but not soon enough to stop southeast winds, and more voggy weather from getting into our area again later this weekend for a day or two. As we get into next Tuesday, the trade winds will once resume their flow across our islands, with those common windward biased showers. I’ll be back again early Thursday morning, I hope you have a great Wednesday night wherever you’re spending it! Aloha for now…Glenn.
Here on Maui: The now retiring cold front has become a dissipating trough of low pressure, over the central islands. As the trade winds return more fully later tonight into Thursday, our weather will finally return to normal…although not for long I’m afraid. Today started off in a nice way, although as this was a transition day, we saw several changes along the way. The vog is still around, as are partly cloudy skies before sunset. This vog will be much less obvious tomorrow, if not completely gone later in the day, which will be a relief for many! The day felt pretty hot and muggy, even here in the upcountry area. The air temperature at the moment, around 6pm, was 73.8F degrees in Kula…while down in Kahului at the same time, was 83 degrees in contrast. Finally, check out the near full moon tonight, which is officially the most full after sunrise Thursday morning.
