Area Forecast Discussion National Weather Service Honolulu HI 815 PM HST Fri Aug 7 2020

SYNOPSIS. Breezy trade winds will prevail through the weekend, then trend down Tuesday through midweek as high pressure to the northeast weakens. Clouds and showers will favor windward and mountain areas each day, especially through the overnight and early morning periods as pockets of moisture move through. Windward shower coverage may decrease later in the weekend and into early next week some drier air moves into the area.

DISCUSSION. Latest surface analysis and satellite imagery showed the subtropical ridge anchored north of the islands and patchy low- level clouds approaching and moving through from east to west. Some of these clouds are generating brief/mostly light showers as they move through - especially over the western end of the island chain where a band of higher than average moisture (PWs up to 2 inches) has setup. Rain gages around the islands reflected this and showed peak accumulations up to near an inch on Kauai in the past 12-Hrs (through 7 pm HST). Elsewhere, accumulations ranged from a few hundredths to a quarter of an inch through this period. Expect the showery and breezy pattern to hold into the weekend in response to this area of higher moisture lingering in the area.

Guidance has initialized well with the current pattern and shows upper heights gradually rising through the weekend as the the upper trough that moved over the past couple of days through continues westward and away from the area. This combined with PWs trending back down toward normal will translate to a slightly drier and more stable trade wind pattern returning by or around Sunday. Trades will become brisk through this time as high pressure strengthens to the north, but should trend down through the first half of next week. Another area of lower heights moving in aloft early next week could enhance shower coverage once again through midweek, mostly for windward and mountain locations.

AVIATION. Moderate trades predominantly out of the east have been relatively dry today suggesting AIRMET SIERRA will not be required in the near term. Improved moisture spreading back into the area during the latter half of the period will bring an increased likelihood of periodic showers and MVFR/mountain obscuration for windward areas.

AIRMET TANGO remains in effect over and immediately south thru west of mountains below 9000 feet for tempo moderate turbulence.

MARINE. High pressure to the north-northeast is expected to strengthen this weekend, which will boost trade winds across the coastal waters. The Small Craft Advisory (SCA) for the typical windier areas near Maui County and the Big Island expands to include Maui Windward Waters, the Kaiwi Channel and Oahu Leeward Waters Saturday morning, through Sunday afternoon. Wind are expected to trend down early next week, which should once again bring the SCA level winds to the typical areas near Maui County and the Big Island.

Surf along south facing shores is expected to return to background levels by Saturday, and remain below summer average into next week. Small short period southeast swell will continue, with the Big Island blocking some of that energy from reaching the smaller islands. Surf along east facing shores will build through the weekend as trade winds strengthen, but is expected to remain below the advisory levels. A small north-northwest swell will provide a bit of energy to the north facing shores, keeping surf just above flat through Saturday.

HFO WATCHES/WARNINGS/ADVISORIES. Small Craft Advisory until 6 PM HST Sunday for Maalaea Bay- Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters.

Small Craft Advisory from 6 AM Saturday to 6 PM HST Sunday for Oahu Leeward Waters-Kaiwi Channel-Maui County Windward Waters.
