Detailed Forecast

Synopsis

A high to the north will maintain breezy trade winds over the area through the weekend. The trade winds are pushing remnants of a front over the islands, focusing showers over mainly windward areas. Rainfall may become heavier and more widespread as deeper moisture spreads over the area from the southeast starting Sunday. Next week, a new high may produce windy weather.

Discussion

A 1033 mb surface high northwest of the main Hawaiian islands is producing breezy northeast to east trade winds over the islands. Radars are showing numerous showers moving over the islands from the northeast. These showers are part of an old frontal band caught up in the trade winds. Breezy trade winds will continue through the weekend. Windward areas will remain rather wet with some showers spreading leeward on the smaller islands, mainly during the nights and early mornings.
The global models are showing deeper moisture spreading over the islands from the southeast starting on Sunday. It is too soon to know the details of this developing pattern, but it looks as if rainfall will become heavier and more widespread starting on the Big Island, then spreading northwest over the other islands. Heavy rain and thunderstorms will be possible on the Big Island with ice and snow over the upper elevations.
Moisture over the islands will subside by the middle of next week. High pressure building far north of the area and a trough developing near the islands may produce very windy weather through mid-week.

Aviation

The remnants of a front remain over the islands overnight, and it continues to bring clouds and showers to the region. Showers are primarily being brought in by the trade winds, with the majority of MVFR conditions being found on the east sides of the islands. Showers have been heaviest west of Maui over the last several hours. AIRMET SIERRA was recently expanded and is now in effect for mountain obscuration for Kauai, Oahu and Molokai.
Conditions on the remaining islands are predominantly VFR, but that could change as parts of the front move down the island chain. High clouds continue to move over the islands from west to east, and are expected to remain overhead through today. No other AIRMETs are in effect or expected in the near term.

Marine

A strong high pressure system far north of the Hawaiian Islands will drift slowly southeastward over the next several days. Trade wind speeds will increase into the fresh to strong range through tonight, and into the strong to near gale range from Sunday through Wednesday. Gale conditions may develop over the windier eastern waters and channels next week.
A Small Craft Advisory (SCA) was expanded in coverage this morning to include all windward waters and most eastern channels today due to a combination of strengthening trade winds and elevated seas. SCA conditions will likely continue for most coastal waters from Sunday onward due to strengthening trade winds and building seas.
The current northwest swell will decrease today as an overlapping northerly swell moves into the region starting later this afternoon through Saturday. This new overlapping northerly swell will bring surf heights along north facing shores to near High Surf Advisory (HSA) levels by Saturday before slowly diminishing on Sunday. The forerunners of the next northwest swell will arrive on Sunday with overlapping northwest and north swell energy producing continued medium size surf along north and west facing shores on Sunday and Monday, then decreasing to smaller size surf on Tuesday and Wednesday.
Strengthening trade winds will increase surf along east facing shores this weekend with a building trade wind swell. Surf will likely reach HSA levels along exposed east facing shores on Tuesday and possibly exceed High Surf Warning levels on Wednesday.
Background south swells will provide small surf to south facing shores through Wednesday.

HFO Watches/Warnings/Advisories

Small Craft Advisory until 6 PM Saturday for all Hawaiian waters except Maui County and Oahu leeward waters.
