Hawaii Weather Narrative

Broad Brush Overview:
Mellow conditions will prevail over the next few days, as a ridge of high pressure is parked just north of the state. Light winds will persist over Kauai and Oahu, while southeast winds blow over Maui County and the Big Island. An approaching cold front will push the ridge over the state Wednesday night and Thursday, bringing lighter winds across the islands. The front will likely bring wet and unsettled weather to portions of the state Friday and early Saturday…as trades rebuild.

Details: Weather maps show high pressure centered far to the east-northeast, with a ridge extending into the area just north of Kauai. The placement of the ridge close to the islands has our trade winds coming in from the east-southeast. These breezes will continue into Wednesday over the Big Island and Maui County…although Kauai and Oahu will see light winds as the Big Island blocks the southeast flow. Look for afternoon sea breezes and nighttime land breezes over Kauai and Oahu, with limited afternoon clouds and showers over interior sections. The rest of the state will see just a few windward showers.

An upper level ridge is limiting any convection over the islands, which will continue over the next few days. The upper ridge will move aside later this week as an upper trough approaches Thursday, bringing instability edging in from the northwest Thursday night and Friday. A cold front associated with the upper trough will push the surface ridge over the state by Thursday, cutting off our winds…allowing widespread afternoon sea breezes and nighttime down slope flow.

Looking Ahead: Look for unsettled weather. as the instability increases and the cold front brings moisture to the area Thursday night and Friday. The front will stall somewhere between Kauai and Oahu Friday afternoon, while high pressure behind the front reinvigorates our northeast trade winds. As the frontal moisture, instability, and island terrain interact, there may be a possibility for heavy showers especially over the western end of the state. The greatest potential for wet and unsettled conditions will be over windward areas…especially along the stalled front.

There continues to be questions, as shower coverage lingers heading into the weekend…although it appears that moderate trade winds will prevail. The latest runs of the GFS and ECMWF models dissipate the front and lift it northward, perhaps leaving some shallow moisture behind to keep showery trades going into Saturday. Both models suggest upper level ridging will build overhead on Sunday, as trade winds hold…favoring a typical pattern of windward rainfall into early next week.

Marine Environmental Conditions: A ridge of high pressure north of the area will slowly move south as a front passes north of the state. Winds are expected to be light and variable across Kauai and Oahu, and moderate to locally stronger out of the east to southeast over Maui County and the Big Island through most of the week. A shift in the weather pattern is possible Thursday night into Friday, as a stronger front approaches from the northwest.

The current northwest swell continues to gradually decrease. A progressive weather pattern will keep surf elevated along north and west facing shores. The next northwest swell is expected to arrive tonight and peak at solid advisory levels by Wednesday morning. A larger, potentially warning level, northwest to north-northwest swell is expected towards the end of the week.

Surf along exposed east facing shores will remain rather small, due to the lack of persistent trades locally and upstream across the eastern Pacific. An increase in surf is possible over the weekend as trades are expected to return.

Surf along south facing shores will remain small through the week. However, minor south swells should be enough to keep things from going flat.

Why are teeth so sensitive to pain?
– You might think of your teeth as tools, like built-in knives and forks. But if they are so utilitarian, why do teeth feel pain? Wouldn’t it be better if they could just gnash and gnaw under any conditions?

In spite of our dental discomfort, it turns out there’s a good reason our teeth are so sensitive.

Tooth pain is a defense mechanism that ensures when a chopper is being damaged, we’ll notice and do something about it, said Julius Manz, director of the dental hygiene program at San Juan College in Farmington, New Mexico, and a spokesperson for the American Dental Association.

“If you eat something too hot or chew something too cold, or if the tooth is worn down enough where the underlying tissue underneath is exposed, all of those things cause pain, and then the pain causes the person not to use that tooth to try to protect it a little bit more. So it’s really a protective mechanism more than anything.”

If teeth didn’t feel pain, we might continue to use them in situations that damage them, Manz said.  And for humans, damaging adult teeth is a problem because, unlike sharks and alligators, we can’t replace them. 

Painful pulp

Teeth have three layers, only one of which — the innermost layer of the tooth — can hurt. That innermost layer of the tooth is called the pulp and contains both blood vessels and nerves. Pain is the only sensation to which the nerves in the pulp respond, Manz said. Whereas people with tooth sensitivity may complain, for example, of tooth pain triggered by heat or cold, the nerves in the pulp don’t sense temperature, Manz said. Rather they feel pain, which may be associated with, say, drinking a very cold milkshake.

Dentin, the middle layer, is alive but without nerves; however, dentin contains fluid that moves around as the teeth move, and the pulp can feel the movement of that fluid. The third, outermost layer is the tooth’s hard white enamel, which is not living and so cannot feel anything.

Afflicted ligament 

Though it’s the only nerve-containing part of the tooth, the pulp isn’t the only source of tooth pain. The periodontal ligament, which attaches the tooth to the jawbone and senses the positioning of the teeth as we chew, can also feel pain. “Anybody who’s been in orthodontic treatment will tell you their teeth are sore. That sensation is coming from the periodontal ligament,” Manz said.

With both the pulp and the periodontal ligament sensing pain, it can be hard for people to know where their tooth pain is coming from, Manz said. Figuring that out, he added, is one of the challenges of being a dentist.
