Hawaiian Islands weather details & Aloha paragraphs

A favorably inclined spring trade wind weather pattern will prevail through the week. Weather maps show a trade wind producing high pressure system located far to the northeast of the Hawaiian Islands Monday evening…well offshore from the northern Baja California coast. This high pressure cell has an elongated ridge of high pressure extending from it, to a point north and northwest of Kauai. The location and strength of this high pressure area will keep light to moderately strong trade winds blowing across Hawaii. The computer models shows this fairly typical trade wind weather pattern remaining in place through at least the next week…probably longer.
 
The windward sides of the islands will see a few showers falling, while the leeward sides for the most part will remain dry. The trade winds will carry clouds in our direction from off the ocean. These clouds won’t be very productive however, in terms of dropping showers. The night and early morning hours will have the greatest likelihood of these few raindrops. The leeward sides will start the week with generally sunny skies during the days, although the Kona slopes on the Big Island, may see some late afternoon showers falling locally. A trough of low pressure aloft, to the west of Hawaii, may send us high and middle level clouds later in the week.

It’s Monday evening as I begin updating this last paragraph of today’s narrative.  It appears that the islands will continue to see generally fine weather through the rest of this month. That fine weather, as noted in the paragraphs above, will include the presence of light to moderately strong trade winds, and those occasional passing showers along the windward sides. During the second half of the week, a stream of high and middle level cloudiness may arrive from the south and southwest…dimming and filtering our famous Hawaiian sunshine for a few days. These are the kinds of clouds that bring spectacular sunrise and sunset colors to our lovely islands! ~~~ By the way, I’ve received several emails lately, from folks wondering if the Humpback Whales were still in our local waters. Well, the answer it yes, they are still around, although it is getting to be towards the end of their long stay. They usually start arriving in October into November, and start the long journey back to Alaska later in March through April. You can see a couple of the responses we received, in relation to whales in Hawaiian waters below. ~~~ Monday was a great day here in the islands! The sun was warm, while the balmy trade wind breezes provided just the perfect amount of cooling relief from the early spring heat. I reckon that Tuesday will be a very similar day, with likely more nice weather traveling with us through the rest of this week. ~~~ I will be back again very early Tuesday morning with your next new weather narrative. I hope you have a great Monday night wherever you happen to be spending it! Aloha for now…Glenn.

Interesting3: Four days after a Kilauea volcano explosion sent debris over a 75-acre area, the possibility of future small explosions remained on the table while lava continued to flow into the ocean, the Hawaiian Volcano Observatory said yesterday in an online update. Sulfur dioxide emission rates at the summit remained at higher than background levels. On Friday the sulfur dioxide emission rate was about 1,200 metric tons a day compared with a background rate of 150-200 metric tons a day. The sulfur dioxide concentration in the air is likely to be hazardous downwind of the vents releasing the gas — in the southern caldera area, the HVO said. The National Park Service has closed Crater Rim Drive through the southern caldera area. Lava flows continued to hold the line on the eastern border. A public viewing area to see the lava flow is open between 2 and 10 p.m. with the last car in at 8 p.m.
