Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.
Gusty trade winds…remaining active well into the future
There will be some passing showers along the windward sides,
mostly at night…just a few elsewhere around the state

We can use the following links to see what’s going on in our area of the north central Pacific Ocean. Here’s the latest NOAA satellite picture – the latest looping satellite image… and finally the latest looping radar image for the Hawaiian Islands.
~~~ Hawaii Weather Narrative ~~~
Our local winds will remain rather strong and gusty…lasting through next week at least. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profile of the central Pacific…focused on the Hawaiian Islands. We have moderately strong high pressure systems located to the northeast and northwest of the state. The models suggest that the trade winds will remain active, with no end in sight, generally in the moderately strong realms…locally stronger around the eastern islands at times.
Satellite imagery shows low clouds around the islands in places…along with some high cirrus clouds around the Big Island. Looking at this larger looping satellite image, it shows those low level clouds riding along in the trade wind flow from east to west. There are a few high cirrus to our north, and those coming up from the south over the Big Island at times. Here’s the looping radar, showing very few passing showers arriving over our islands at the time of this writing. The windward sides will receive most of these showers, which may increase a bit tonight into early Friday morning, although the leeward sides will find much fewer during the night.
There will be subtle changes in both wind speed and rainfall…although weather through the 4th of July holiday will remain favorably inclined. The trade winds will slowly rebound in strength into Friday, lasting through the next week at least. As is often the case, most showers that grace our shores and slopes will occur during the night and early morning hours. The overlying atmosphere remains quite dry and stable, which will limit showers some, especially later Friday into the weekend. There are those common patches of showery clouds upstream, which will bring some moisture our way periodically. I’ll be back again early Friday morning with your next new weather narrative, I hope you have a great Thursday night wherever you’re spending it! Aloha for now…Glenn.
Here on Maui, at the 3,100 foot elevation, at my upper Kula, Maui weather tower, the air temperature was a 61 degrees at 550am on this Thursday morning. Skies are clear overhead for the most part, while the windward sides have some passing clouds and a few showers…which stretch over the West Maui Mountains as usual. The overnight clouds, which are a bit more extensive than usual, will thin out during the day in most areas, with more early summer weather on tap.
We’re into the early evening hours now at 530pm, under partly cloudy skies, light breezes…and an air temperature of 80.6 degrees.
World-wide tropical cyclone activity:
Atlantic Ocean: Hurricane 01L (Arthur) remains active…and will be coming down in strength from here on out. Here’s the NHC graphical track map…along with a satellite image. Here’s what the hurricane models are showing for this tropical cyclone.

Caribbean Sea: There are no active tropical cyclones expected through the next 5 days
Gulf of Mexico: There are no active tropical cyclones expected through the next 5 days

North Eastern Pacific: Tropical Storm 04E (Douglas) remains active, and will be weakening further over the next few days. Here’s the NHC graphical track map…along with a satellite image. Here’s what the hurricane models are showing for this tropical cyclone.

South Pacific Ocean: There are no active tropical cyclones
North and South Indian Oceans: There are no active tropical cyclones

Interesting: EPA Proposes New Standards for Landfills…Hopes to Reduce Methane Emissions – As part of the President’s Climate Action Plan — Strategy to Reduce Methane Emissions, the U.S. Environmental Protection Agency (EPA) is proposing updates to its air standards for new municipal solid waste (MSW) landfills. These updates would require certain landfills to capture additional landfill gas, which would reduce emissions of methane, a potent greenhouse gas, and help further reduce pollution that harms public health.
Non-hazardous waste from homes, business and institutions ends up in municipal solid waste landfills, where it decomposes and breaks down to form landfill gas, which includes carbon dioxide, a number of air toxics and methane. Methane has a global warming potential 25 times that of carbon dioxide.
“Reducing methane emissions is a powerful way to take action on climate change,” said Administrator Gina McCarthy. “This latest step from the President’s methane strategy builds on our progress to date and takes steps to cut emissions from landfills through common-sense standards.”
This proposal would require new MSW landfills subject to the rule to begin controlling landfill gas at a lower emissions threshold than currently required. Under the proposal, landfills would capture two-thirds of their methane and air toxics emissions by 2023 — 13 percent more than required under current rules. EPA estimates the net nationwide annual costs of complying with the additional requirements in the proposed rule would be $471,000 in 2023.
Today, methane accounts for nearly 9 percent of all greenhouse gas emissions in the United States, and landfills are the third-largest source of human-related methane in the country, accounting for 18 percent of methane emissions in 2012. Regulatory and voluntary programs, including the agency’s Landfill Methane Outreach Program, have helped reduce emissions from landfills by 30 percent from 1990 to 2012. However, without additional actions, methane emissions are projected to increase through 2030.
The EPA has also issued an Advance Notice of Proposed Rulemaking (ANPR) seeking broad public input on whether and how to update current emissions guidelines for existing landfills to further reduce their emissions, including methane. The agency is considering updating those guidelines based on a several factors, including significant changes that have occurred in the landfill industry since the original guidelines were issued in 1996. Nearly 1,000 MSW landfills in the U.S. currently are subject to either the 1996 emission guidelines for existing landfills or the 1996 NSPS for new landfills.
