Detailed Forecast

Synopsis

Breezy trades will become locally strong Thursday night into Friday. The stalled remnants of a cold front will support wet conditions over Windward Kauai into the first half of the weekend while a gradual drying trend can be expected elsewhere.

Discussion

Locally breezy trades will further strengthen today as mid- level ridging near the Dateline expands eastward and allows surface high pressure to reestablish over the central Pacific. Additional strengthening of trades is forecast late this week with locally strong trades possible late tonight into Friday. Throughout this time, the resident band of frontal moisture will support cloudy and wet conditions over Windward Kauai and, at times, Windward Oahu. This band of moisture continues to demonstrate a healthy appearance on satellite which lends itself to increased confidence in wetter-than-normal conditions. However, limited moisture depth and lack of greater synoptic forcing preclude concerns for heavy rain at this time. Regional model analyses and the CIMMS MIMIC PWAT product indicate a drier airmass extending from about 150W, just east of the Big Island, to the Southern California/Baja coast. Trades will slowly but surely advect this drier airmass across the state during the next several days bringing a drying trend from east to west. Generally speaking, drier conditions and greater low-level stability will reach the Big Island early Friday morning and the central portion of the state by late Friday. Given the increasingly flow-parallel orientation of the frontal band over Kauai, model depictions of its stubborn departure westward are believable. Taken at face value, the latest GFS suggests drier trades may not take hold over Kauai until Saturday night or early Sunday, though exact timing will be subject to adjustment. Trades will begin to weaken during the first half of next week as ridging runs its course and a fresh round of heights falls over the north Pacific gets underway.

Aviation

Moderate trades will persist today and help generate scattered showers along windward locations of all islands. The remnants of a dying front north of Kauai will bring enhanced low level moisture and shower activity to windward Kauai and Oahu. They activity may bring brief periods of MVFR ceilings and visibility. Otherwise, partly cloudy skies and VFR conditions expected elsewhere.
No AIRMETs are currently in effect.

Marine

A northwest to north swell will subside and shift out of the northeast today. For the rest of the week and into early next week, expect small to moderate surf along north and west facing shores as a series of small to moderate northwest swells fills in. Expect moderate east facing shores surf today as the current north to northwest swell shifts to the northeast. In addition, strengthening trades will hold the surf heights in the small to moderate range along east facing shores into early next week.
Trade winds will strengthen today and hold through the weekend. A Small Craft Advisory (SCA) for waters northwest and lee of Kauai and for the windier waters around Maui County and south of the Big Island is now in effect. This SCA will likely continue through the weekend.
