Area Forecast Discussion
National Weather Service Honolulu HI
334 AM HST Fri Mar 12 2021

.SYNOPSIS...
The wet pattern will continue as a front and upper disturbance
approach and advance down the island chain later today through
Saturday. Heavy showers and a few storms along and ahead of the
front combined with saturated grounds will keep the threat for
localized flash flooding in place across the state. Brisk trade
winds will follow the front, which will focus clouds and showers
over windward and mountain locations. A wet trade wind pattern
will be possible Sunday through the first half of the upcoming
week.

&&

.DISCUSSION...
Low pressure positioned west of the state will begin to lift
northeastward and phase with the tail-end of a cold front passing
to the north later today. Moist convergent southerly flow in
place over the islands east of this feature combined with an upper
trough will continue to support localized heavy rainfall and a
few thunderstorms across the islands today. The low-level flow
will shift out of the southwest later today as the front
approaches, then to the northeast tonight into Saturday over the
western end of the state. Despite the return of strong trades over
Kauai and Oahu, rainfall chances will remain up into the weekend,
especially over windward and mountain locations. More widespread
rainfall and even a few storms will be expected over the eastern
end of the state through Saturday as a potent shortwave trough and
the cold front advance down the island chain. As a result, the
Flash Flood Watch has been extended through early Saturday.
Additionally, winter weather conditions can't be ruled out over
the Big Island Summits tonight through Saturday as this upper
trough moves in.

Brisk trade winds should return statewide by the end of the
weekend trailing the front, which will focus clouds and showers
over windward and mountain locations. Forecast confidence
diminishes for early next week due to considerable model changes
from cycle to cycle. The latest model solutions now depict more
of a wet pattern unfolding as an area low pressure drifts
westward through islands. Confidence should improve over the
weekend as conditions evolve.

&&

.AVIATION...
A surface low to the northwest of Kauai, combined with an upper
level trough, will allow for more rounds of unsettled weather to
persist over the next several hours. Expect MVFR or even IFR
ceilings and visibility to occur with some of the heavier shower
activity. In addition, isolated thunderstorms will remain
possible due to the unstable air aloft.

Light southerly winds will shift southwesterly across Kauai and
Oahu as the day progresses, then to the northeast tonight.

AIRMET SIERRA remains in effect for Kauai, Molokai, and Maui
above 2500 feet due to clouds and showers.

AIRMET ZULU remains in effect for Kauai and adjacent waters
between 15000 and 25000 feet due to tempo light icing.

&&

.MARINE...
A slow moving low pressure system west of Kauai will keep gentle
southerly winds across Hawaiian waters today. A frontal system
will move through the northwestern offshore waters today and into
the coastal waters from tonight through Sunday. Strong to near
gale northeast trade winds will build in behind the front as it
moves into the region. Widespread heavy showers and thunderstorms
will continue into the weekend with this unstable system. Unsettled
fresh trade winds will continue into next week with an upper
level disturbance keeping periods of wet weather in the long range
forecast.

A background east swell will keep moderate surf heights along
east facing shores into the weekend. This east swell will slowly
fade from Saturday night through Monday. A high pressure system
building into the central Pacific early next week will increase
east swell heights from Tuesday onward. Small surf heights along
north and west facing shores will continue today. A new large
medium period north to northeast swell will arrive early Saturday
morning quickly building surf heights along north and east facing
shores to near High Surf Advisory (HSA) levels through the
weekend. Small surf along south facing shores will rise a bit
today and Saturday as a swell originating west of New Zealand
reaches the area.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
Flash Flood Watch through late tonight for all Hawaii islands.

Small Craft Advisory from 6 PM this evening to 6 PM HST Sunday
for Kauai Northwest Waters-Kauai Windward Waters-Kauai Leeward
Waters-Kauai Channel-Oahu Windward Waters.
