FXHW60 PHFO 181305 AFDHFO

Area Forecast Discussion National Weather Service Honolulu HI 305 AM HST Thu Apr 18 2024

SYNOPSIS
Mostly dry and pleasant trade wind conditions will prevail through next week. Breezy northeast trade winds will briefly weaken over the weekend, then shift out of the east and return to breezy levels early next week. Clouds and brief showers will favor windward and mauka locations overnight through the mornings as areas of moisture move through periodically.

DISCUSSION
The latest model guidance has initialized well with the current pattern and depicts mostly dry conditions prevailing through next week as high pressure builds north of the state. The low-level flow has shifted out of the northeast and will reach the breezy category through the day today. Despite the dry conditions in place, a weak upper trough moving through combined with a remnant low-level moisture boundary settling south into the smaller islands this morning supports scattered light showers, mostly over windward areas of Oahu and Kauai. This band of moisture will linger into tonight, then diminish.

The breezy trades will hold Friday, but ease into the light to moderate range over the weekend as a weakness forms in the ridge due to a system passing far to the north. The southern extent of a mid- to upper-level trough associated with this system will pass nearby to the north through this time, which could support a slight increase in windward shower coverage through the overnight/morning periods. Rising upper heights along with a strengthening surface ridge to the north will support the dry conditions prevailing early next week with breezy easterly trades returning.

AVIATION
Surface high pressure northwest of the state will continue to drift eastward during the forecast period and maintain light to moderate northeasterly trades across the state. Thus, scattered shower activity will mainly affect windward locations. Expect brief periods of MVFR ceilings and visibility to be associated with this activity today, especially for Kauai and Oahu. VFR conditions elsewhere.

AIRMET SIERRA has been issued above 2000 feet for north through east sections of Kauai for tempo mountain obscuration from low clouds and showers.

MARINE
Moderate northeast trades will persist through the forecast period possibly strengthening slightly during the weekend.

Small surf along south facing shores will hold as overlapping south swells maintain elevated surf through the end of the week.
The current northwest swell will become increasingly north as it gradually subsides through today. A small north swell will bring a modest bump to exposed shorelines during the latter half of the weekend. Surf along east facing shores will remain small.

HFO WATCHES/WARNINGS/ADVISORIES
None.
