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.
Major high surf event…be very careful on the north and
west shores through Friday!
We’ll find southwest winds continuing…generally on
the light side
A weak cold front will bring an increase in showers locally
Thursday, with another late Sunday evening…and then
a stronger cold front around the middle of next week –
followed by generally dry, sunny weather next Friday
into the weekend…although quite chilly at the same time
High Surf Advisory…north and west shores of all the
High Surf Warning…north and west shores of Kauai,
Oahu and Molokai, and the north shore of Maui
Small Craft Advisory…all coastal and channel waters

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 ~~~
Light southwest winds, with a brief period of trade winds returning Friday and Saturday, then back to light and variable breezes Sunday…with a return to southeast through south and southwest into early next week. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean. ~~~ We find a near 1037 millibar high pressure system far to the northeast of the state, with an associated ridge of high pressure extending southwest, to the south of the Big Island. At the same time, we see gale and storm low pressure systems well to our north, with the tail-end of its associated cold front over the ocean to the northeast of the Big Island. We also see another cold front to our northwest, advancing towards our state. These weather features will keep our winds from the southwest, becoming somewhat stronger as the cold front to our northwest gets closer Thursday.
Satellite imagery shows generally clear to partly cloudy skies over the state, with a few cloudy areas as well. There are a few areas of clouds, most notably around Kauai and Oahu, and down around Maui and the Big Island. Here’s the looping radar image, showing a few light showers falling over the ocean locally, coming into our leeward sides in a few places at the time of this writing. Looking at this larger satellite image, which is in the looping mode, we can see that area of deep clouds to our east moving away at this point. At the same time, we can see a frontal cloud band to the northwest, with what looks like a band of clouds just out ahead of the front itself…moving quickly in our direction.
A weakening cold front will arrive over Kauai, Oahu, and perhaps part of Maui County Thursday…bringing an increase in showers. The latest computer model runs now show that this front may run out of steam before making it down to the Big Island. This will be the first of a couple of weak cold fronts, with another slated to arrive late in the weekend into early next week. Then, and more importantly, the models go on to show yet another cold front, this one is expected to be much stronger, forecast to arrive by the middle of next week. There will need to be fine tuning for all of the above, which is common during our more unsettled winter season. Speaking of the winter season, and with all these gale and storm low pressure system churning the waters of our north Pacific, we’ll see large and very large high surf events during the next week. These will require great caution when getting near the ocean on our north and west facing shores! ~~~ I’ll be back again early Thursday morning with your next new weather narrative, I hope you have a great Wednesday night until then! Aloha for now…Glenn.

Interesting: Why Cold Air Smells Different – Pine needles. Wood smoke. Snow. These are the smells of winter, and for people who live with distinct seasons, wintry weather brings its own set of olfactory experiences. But why does the cold of winter smell different from the heat of summer?
One reason is that odor molecules move much more slowly as the air temperature drops, said Pamela Dalton, an olfactory scientist at the Monell Chemical Senses Center in Philadelphia. That means that there are simply fewer smells to smell on a cold, crisp day than there are on a hot and humid one.
It’s the same reason why hot soup smells more than cold soup does and why the garbage truck leaves behind the strongest odors on steamy summer days.
What’s more, our noses don’t work quite as well when the ambient air is cold, Dolan said. In experiments that require biopsies of olfactory receptors that lie deep inside the nose, researchers at Monell have discovered that the receptors “bury themselves a little more deeply in the nose in winter,” she said, possibly as a protective response against cold, dry air.
“We’re not as sensitive to odors in winter,” she added. “And odors aren’t as available to be smelled.”
Cold air also stimulates the irritant-sensitive trigeminal nerve, said Alan Hirsch, a neurologist and psychiatrist in Chicago. The trigeminal nerve is what makes you cry when you chop an onion and delivers a hit of spiciness when you inhale a whiff of strong mint.
When odors stimulate both the trigeminal nerve and the olfactory nerve, the experience of smell becomes more intense.
There is a strong psychological component to our sense of smell, Hirsch added, and what we expect to smell has a big influence on what we actually smell.
