Weather Chart – Here’s the latest (automatically updated) weather map. A high pressure ridge extending west from a small high pressure system just to the east-northeast of Hawaii…is now back down over Maui County. This pressure configuration will cause light winds across the state into Saturday. Here’s a Weather Map Symbol page for clarification about what all those weather symbols mean on the map.
Satellite and Radar Images: To view the cloud conditions we have here in Hawaii, please use the following satellite links, starting off with the Infrared Satellite Image of the islands to see all the clouds around the state during the day and night. This next image is one that gives close images of the islands only during the daytime hours, and is referred to as a Close-up visible image. This next image shows a larger view of the Pacific…giving perspective to the wider ranging cloud patterns in the Pacific Ocean…out from the islands. To help you keep track of where any showers may be around the islands, here’s the latest animated radar image.
Hawaii’s Mountains – Here’s a link to the live webcam on the summit of near 14,000 foot Mauna Kea on the Big Island of Hawaii. The tallest peak on the island of Maui is the Haleakala Crater, which is near 10,000 feet in elevation. These two webcams are available during the daylight hours here in the islands…and when there’s a big moon rising just after sunset for an hour or two! Plus, during the nights and early mornings you will be able to see stars, and the sunrise too…depending upon cloud conditions.
Light winds in general, from varying directions, will continue into Saturday morning. We’ll find locally breezy south to southeast winds arriving later Saturday into Sunday, associated with an active cold front arriving later in the day Sunday into Monday…followed by cool north breezes after it passes through. Light trade winds will return again for a few days thereafter. We may see some form of light south to southwest winds develop as another cold front approaches the state around the middle of next week.
The overlying atmosphere is unusually dry and stable, with hardly a drop of water falling from the sky anywhere. The days will start off in a mostly clear way, and generally will end up that same way in most areas. The exceptionally dry conditions will keep whatever few showers that happen to break loose from these clouds, to a bare minimum at best…with most areas remaining totally dry. The computer models continue to show a showery cold front arriving later Sunday into Monday, followed by more dry weather as we move into the first several days of next week.
It’s Thursday evening as I begin updating this last paragraph of today’s narrative. Dry, dry, dry, that’s the name of the game here in the Hawaiian Islands now! 99.9% of all the rain gauges across the Aloha state remained dry as a bone during the last 24 hours. Actually, all this week has been very dry indeed. I see little change in this situation through Friday into Saturday. As we move through the day Saturday however, and as the kona winds develop ahead of Sunday’s cold front…we may see a few showers falling along the leeward coasts and slopes later in the day. We call this kind of precipitation, prefrontal showers, although with such dry atmospherics, they won’t amount to much. The main event, although that may be too dramatic a label for what will actually happen…will be the shower producing cold frontal passage later Sunday into Monday. This doesn’t look like too much of a big deal, with most of the showers sticking pretty closely to the windward sides of the islands from Kauai down through Maui. This quickly weakening frontal boundary may be mostly dissipated by the time it makes its way over the northern part of the Big Island Monday. This will be a brief affair, with more good weather on tap as we move into next week. The next possible chance of a cold front, with a brief period of showers, would arrive around next Thursday. ~~~ Thursday was another one of those mostly clear days here in Hawaii, with just a few thin clouds forming over the mountains during the afternoon hours. I happen to be in Kula, Maui, an upcountry area, and it’s definitely mostly clear just before sunset. There is some volcanic haze around, and I understand that the Big Island is having some thick vog down there! Thursday night will be a cool one, as there are so few clouds, remaining that way through the night. Friday will begin the same way that Thursday did, with mostly clear skies just about everywhere. ~~~ I’ll be back very early Friday morning with your next new weather narrative from paradise. I hope you have a great Thursday night, which will be well lit by the just past February full moon! Aloha for now…Glenn.

Interesting2: Tiny particles of pure silica coated with an active material could be used to remove toxic chemicals, bacteria, viruses, and other hazardous materials from water much more effectively and at lower cost than conventional water purification methods, according to researchers writing in the current issue of the International Journal of Nanotechnology. Peter Majewski and Chiu Ping Chan of the Ian Wark Research Institute, at the University of South Australia, explain that the availability of drinking quality water is fast becoming a major socio-economic issue across the globe, especially in the developing world. However, water purification technology is often complicated, requires sophisticated equipment and is expensive to run and maintain. Moreover, it usually requires a final costly disinfection stage. The Australian team suggests that nanotechnology could provide a simple answer to the problem.
Glenn’s TV Weather show is back online now. One day’s show will replaced with the next new days show at around 930am HST (1130am PST – 230pm EST)…Monday through Friday. Thanks to the folks at the Maui Media Lab in Paia for making this happen! I was just informed that about 100 people a day are taking the time to watch the show, thanks for your viewership!
