~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Aloha Friday comments: I’m at home here in upper Kula, Maui, Hawaii

Good day everyone, I hope you have a great Friday wherever you happen to be spending it.

511am, it’s a mostly clear morning, with a low temperature of 51 degrees.

604am, despite the clear skies here on the leeward slopes of the Haleakala Crater, I see considerable cloudiness over along the windward sides of Maui…along with some showers too.

 

Hawaii’s Broad Brush Weather Overview:  The high pressure center far north of the Hawaiian Islands will build, producing breezy trade winds across the area for the next several days. An upper level disturbance will enhance passing showers into early next week, favoring windward and mountain areas in the overnight to early morning hours. A few of the stronger showers will drift into leeward areas.

Long range guidance shows an old frontal cloud band moving into the islands from the northeast by early next week Wednesday. This cloud band may bring another brief round of wet weather to all islands from Wednesday morning into Thursday.

Hawaii’s Weather Details:  Radar imagery shows a fairly wet weather pattern over most island windward and mountain areas. These enhanced shower trends will tapper off a bit by mid-morning to afternoon, then a return to more showers later this evening.

Satellite imagery continues to track an unstable upper low northwest of Kauai, with an upper level trough lingering over the state. A subtropical jet stream is also evident near the islands. Upper level divergent forcing will continue to keep enhanced showers in the forecast for the next several days.

Two high pressure systems in the Central Pacific, far north of the Hawaiian Islands, will consolidate into one high center soon. This high will build slightly just north of the Hawaiian Islands, and increase trade winds into breezy range into Monday.

By Monday afternoon the high begins to drift eastward away from the islands, with a frontal trough moving into the Central Pacific basin. This change in large scale pressure patterns north of the islands will decrease trade wind speeds, back to more moderate levels Monday night onward.

Expect continued enhanced showers across the state, as the unstable upper level disturbance slowly drifts eastward across the island chain. Most of the rainfall will favor windward and mountain areas, as breezy trade winds carry clouds up and over the windward mountain slopes.

Down sloping trade wind flow over the leeward sides of island mountain ranges will tend to decrease shower activity for leeward areas. Showers will tend to increase during our typical diurnal rainfall maximum in the overnight to early morning hours.

In the extended forecast there continues to be a long band of unsettled shallow clouds, remnants of an old Eastern Pacific cold front, drifting into the islands on the moderate trade winds Wednesday morning into Thursday. This cloud band may produce wet weather over all islands for an 18 to 24 hour time period.

The highest rainfall amounts will tend to favor windward areas, however many leeward sites may also see measurable rainfall totals with this next system. This fairly shallow cloud band will likely not be deep enough to produce heavy rainfall, rather more beneficial rain for all islands.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map

Marine Environmental Details:  Fresh to locally strong winds have arrived, as high pressure builds far north of the state. These stronger trades will continue through the weekend, and then drop a notch or two early next week, as the high moves far northeast of the state.

The Small Craft Advisory (SCA) for typical windy waters around Maui and the Big Island has been expanded to all waters through early Monday morning. Some area may drop out earlier as winds begin to ease due to the high shifting northeast.

Tiny surf will persist along north and west facing shores. Forerunners of a northwest swell is expected to fill in this afternoon and peak Saturday, bringing small surf along north and west facing shores. Another small northwest swell will fill in late Sunday, maintaining small surf along north and west facing shores into early next week.

Small south swells will continue into Saturday, providing tiny surf for south facing shores. Forerunners of a small south swell may arrive Saturday afternoon, with a slow onset through Sunday providing a boost in surf along south facing shores into early next week. Rough and choppy surf along east facing shores will bump up a notch Saturday and hold hold into early next week as strong trades hold.

Interesting: Texans Should Prepare For Hotter Temperatures, Greater Risk Of Fire And Flooding

Weather conditions across the Lone Star State are getting more extreme and more dangerous by the year, according to a new report from Texas A&M University professor and State Climatologist John Nielsen-Gammon.

The newly updated assessment of extreme weather in Texas draws on data from 1900-2023 to predict trends through the year 2036, and shows a significant uptick in extreme temperatures and droughts, wildfire conditions and urban flooding risks, among other changes.

The report was authored by Nielsen-Gammon, a Regents Professor in the Department of Atmospheric Sciences, in collaboration with the nonprofit public policy organization Texas 2036.

“We have national climate assessments, but they can’t do justice to Texas’ specific climate conditions,” Nielsen-Gammon said. “With this Texas-specific study, we focused on observed trends as much as possible rather than emphasizing climate model projections. The historic climate trends are part of our lived experience in Texas, and our report puts them in long-term context.”
