Weather

Synopsis
Weakening trade winds will diminish further on Friday, with sea breezes becoming more prominent by day and land breezes at night. Shower activity will shift from windward slopes mainly at night and during the morning to interior and leeward areas each afternoon, though rainfall amounts should remain modest.

Discussion
Water vapor imagery shows an upper level low northeast of the state, gradually moving northward, with a larger low far to the north. A ridge is located just north of the state between the two lows. At the surface, high pressure is located far to the north-northeast, with surface troughs to the east and to the far north-northwest of the state. 12Z soundings from Lihue and Hilo show weak inversions around 10kft. Precipitable waters range from 1.31 inches in Lihue to 1.13 inches in Hilo. Early morning mimic total precipitable water imagery shows pockets of similar moisture extending a couple hundred miles north and northeast of Kauai, with an area of drier air between 50 and 150 miles northeast of the remaining islands.

The upper level low northeast of the state has begun to move northward and weaken, eventually to be absorbed into the digging upper low well north of the state. As this occurs, weak subsidence associated with building mid-level heights will briefly help to strengthen and lower the inversion, though a lingering upper level trough over the northwest half of the state will keep the airmass somewhat unstable. Model cross sections show the current elevated moisture depth lingering into Friday before diminishing over the weekend. Rainfall amounts have been higher over kauai/big island, with a quarter to a third of an inch inch in the past 12 hours compared to a tenth of an inch elsewhere. A band of clouds approaching windward oahu/maui county will enhance windward showers this morning. Otherwise we should see an increase in interior/leeward showers this afternoon. Yesterday we had a few heavy showers develop across leeward Maui and Big Island. The atmosphere may be a bit more stable than yesterday, but the potential for localized heavy rainfall still exists.

12Z models show the high will shift northward and actually strengthen through the weekend. However, the surface trough to our east will shift northwest and pass between us and the high, keeping the gradient light across the islands. Initially the gradient will weaken slightly over on Friday, then further diminish over the weekend as a weak low develops north of the area along the trough. Light trade winds will give way to increasing sea breezes by the weekend. It appears that there should remain enough of a background gradient to keep some showers focused across windward sections at night, with the bulk of the clouds and showers occurring across interior and leeward sections during the afternoon and evening. A multi-model blend of precipitable water fields shows a downward trend from this evening into Friday, with below normal moisture values heading into the weekend. The drier and more stable airmass will limit rainfall amounts.

Aviation
Light to moderate trades will remain with VFR dominating the area. Clouds and showers embedded in the trade winds flow will favor windward and mountain areas, with isolated MVFR cigs/vis. Afternoon showers with tops to 15 thousand feet are possible along the leeward slopes of the Big Island and Haleakala.

Marine
Weak winds and small swell will keep conditions below the threshold for a small craft advisory through early next week.

Watches/Warnings/Advisories
None.

Big Picture

Big Picture 6/11/15 Thursday

All Shore Surf synopses: Tiny summer time NW boost Thursday-Friday keeps us from the doldrums. Then we rely on NE swells to wrap in. There are hints of back ground WNW pulses all under 2’ over a week or 2 out. An 8 sec NE swell builds Friday and lasts into next week from former Hurricane Blanca peaking at 3’ at top select reefs. Town gets a better outlook as the first SSW fills all day Friday 12th, peaks Saturday at overhead. Then one week out Friday the 19th a much better SSW builds to 4’ in the afternoon and hits advsry levels over the weekend! (No, not as big as June 1st swell. That one could be the best, biggest we see all summer). Let’s hope not.
NPAC
The Jet is still below the Aleutians tho’ the winds are soft and there’s not really much for real surface Low support.

Recent/Current: It was all about that fat WNW that hit 6’ Sat June 6th from that NW gale in the NPAC the week prior.

Next: Last weekend a weak near gale Low spun far NW over 2000 miles away at first and reached the dateline early this week to push off some 2’ 12 sec NW swell on the buoys today Thursday into Friday refracting surf to chest high sets if lucky into Friday.

Next: Former Hurricane Blanca pushed out some small 10 sec NE surf for this Friday-Monday but only hitting maybe 3’ for select reefs like Laniakea and isolated Windward reefs.
http://www.nhc.noaa.gov/text/refresh/MIATCPEP2+shtml/090837.shtml

Next: A low pushes off the West coast this Friday-Sunday for some 12 sec NE swell Tuesday-Thursday up to 3’ for again only select spots if models pan out.

Last: Very distant Low near Japan tries to get something to us but WW3 says only shin high surf with 11 sec around the 18th. We only mention this due to that fact that seeing anything this time of year is low probability.

SPAC:
The Jet is working well for the Taz and off the east of NZ over the next week or so. The High to its East is also helping out the NE bound fetches. The Northern branch is zonal. The Southern branch flows NE and does end up right over NZ but the storm at the surface is still able to move off the east coast and deliver the kind of storm we love. See last below.

Recent/Current: We have back ground 2’ SSW swell from a Taz Low about a week ago.

Next: A Low tracked ENE last Thursday SE of NZ with a long NE fetch but most the power within the fetch is over 4500 miles away allowing for more swell decay and more inconsistent sets this Friday-Saturday. SSW surf should hit head high or 3’ local size Saturday. It’ll drop to chest high Sunday and fade from there. Winds will be calm to light and seabreezes will mush out all surf spots into Monday. It’s a go early or late scenario so expect crowds.
We go to 2’ Monday and hover until the real deal fills Friday!

Last: A winter Low SSE of NZ fills the area with slow ENE track this Friday-Sunday 12-15th. A real good long lasting SSW will be on the 7 day journey reaching the buoys with 18 sec forerunners Thursday nite and getting 2.5’ 16 sec by 8am Friday. This equates to solid 4’ sets at top spots before Noon Friday tho’ there’ll be long waits. The Saturday peak should see SSW surf up to 5’ local or 4’ overhead. The 16 seconds will give some reefs the chance of hitting 6’. Sunday will still be cranking and it’s not till Monday when surf drops below Advsry levels of 8’ crest to trough.
Windward: it’s the usual fluctuation of 2’ to 3’ pending trade speeds. Right now we’re going into tiny mode without the regular trades. However, the Hurricane season will make up the lack with alittle NE (Blanca) surf at 1-2 barely 3’ Friday-Saturday.

Tropics: It’s been record breaking. This is the earliest on record, since 1971 that two major hurricanes have formed in the Eastern Pacific. There have been four other seasons that have had two major hurricanes develop before the end of June. While Andres brought only rough surf and rip currents to Mexico, Blanca brought more direct impacts Baja California. We get small NE swells and if this current trend continues we’ll keep getting what we got. Carlos is the next one but Hawaii wont be able to claim a swell.
Hurricane Carlos is spinning off the coast of southern Mainland Mexico, becoming 3rd named system of the season. This storm will strengthen over the next day or so, while staying over the warm waters off the Mexican coast and delivering plenty of swell to the region.

FETCH: Often called the fetch length, is a term for the length of water or distance over which a given wind direction has blown. Fetch length along with the wind speed (or strength) determines the size of waves produced. The longer the fetch length and the faster the wind speed, the larger and stronger the wave will be and vice versa.
CAPTURED or FOLLOWING FETCH: Not only does the fetch length determine the power and energy of the wave. Additionally, if the winds/fetch are blowing in the same direction as during the wave's or storm's lifetime, the wave will in turn be even stronger. The fetch is related to the orbit of the wave and track of the storm.The longer the wind drags along the sea the more energy the wave will have. This can be seen not just in vertical height measurement but in wave period (the measurement of waves through time).
WAVES PERIOD:Time, in seconds, between the passage of consecutive wave crests past a fixed point. In general the longer the period the bigger the wave. Windswell or 'close interval' swells are under 10 seconds. Big 'ground swells' are 17-20+ seconds (note: a 20+ second swell needs storm force 50+kt winds blowing over a 1500 mile fetch to be fully developed' into 20-25' beasts; these 20 second waves can be felt 1000 feet down!). This is why they jack so much more, pulling large amounts of H2O off the outer reefs.
