Area Forecast Discussion National Weather Service Honolulu HI 906 PM HST Sat Apr 13 2024

SYNOPSIS
The potential for heavy rainfall and thunderstorms associated with a front will continue through Monday, initially over the western end of the state through late Sunday, then over the eastern end on Monday. Conditions will gradually improve from west to east through the first half of the week as high pressure builds to the north in the wake of the front. Breezy southerly winds ahead of the front will hold through Sunday, then ease into the light to moderate range as they shift to the north, then to a more typical trade wind direction around midweek. Expect a more typical trade wind pattern to return with showers favoring windward and mauka locations through the second half of the week.

DISCUSSION
The short-term guidance remains in good agreement and depicts the active weather pattern persisting through Monday due to an upper low to the northwest and its attendant surface front nearing Kauai. The initial threat will be over the western end of the state through Sunday night, with a transition to the eastern end on Monday. The latest radar imagery showed a healthy line of showers over the Kauai Channel this evening, slowly approaching Oahu. If this line holds together, it should begin to move through Oahu later this evening or around midnight. Rainfall gauges on Kauai showed additional amounts ranging from a quarter to around half of an inch as it moved through earlier this evening.

Later tonight through Sunday, guidance reflects another shortwave pulse rotating through the upper-level trough to the northwest, which could be the trigger for the next round of heavy showers and storms for Kauai and Oahu. Provided the saturated soils and elevated streams from the heavy rainfall over the past few days, it won't take much for them to respond once the heavy rainfall sets up and focuses over the island. As a result, the Flood Watch remains in effect and will likely be expanded to include Oahu and potentially Maui County in the early Sunday morning package.

In addition to the threat for heavy rainfall, a few thunderstorms could become strong provided the instability and shear profiles, particularly over Kauai and Oahu late tonight through Sunday.
Also, breezy southerly winds could translate to strong downsloping winds over windward areas through this time, especially in the heavy showers/storms moving through.

A drying trend is anticipated from west to east, beginning over Kauai late Sunday night, then over Oahu through the day Monday as the front advances eastward to Maui County and the Big Island.
Conditions should steadily improve over the eastern end of the state around the midweek time frame as the upper level trough exits or shifts northeastward and away from the state. The low- level flow will return to a more typical trade wind direction Wednesday through the second half of the week as surface high pressure builds north of the state.

AVIATION
The tail end of a Central Pacific cold front will graze the western Hawaiian Islands tonight and tomorrow. An organized band of intense showers associated with the frontal boundary can be seen on evening radar in the Kauai Channel marching slowly eastward. These showers and possible embedded thunderstorms are expected to reach Oahu Sunday morning and the Ka'iwi channel in the afternoon.

Surface winds will veer from southeast to west-southwest with the frontal passage. Ahead of the front, light showers will favor south and southeast facing slopes and coasts. Behind the front, moderate showers and possible thunderstorms will favor west and southwest facing slopes and coasts.

AIRMET Sierra for mountain obscuration will likely be needed on Sunday for Oahu and Kauai. From Molokai trough Big Island, brief MVFR conditions in passing showers are to be expected, but VFR conditions should nevertheless prevail.

AIRMET Tango remains in effect for moderate upper level turbulence between FL180 and FL380. These conditions will likely hold through tonight.

AIRMET Zulu remains in effect for moderate rime icing in cloud, in precipitation, between FL230 and FL280 due to layered clouds over and around the Big Island. This AIRMET will likely be needed through tonight.

MARINE
South to southeast winds will strengthen tonight ahead of an approaching front to the west. A Small Craft Advisory remains posted for coastal waters west of and including the Kaiwi Channel due to winds. The front will slowly push southeast through Monday, before stalling out and slowly dissipating near the Big Island Tuesday and Wednesday. Light to moderate west to northwest winds will fill in behind the front. Winds will become rather light by Monday night and continue through next Wednesday, with moderate trades potentially returning for the latter part of next week.

North shore surf will remain small through the rest of the weekend. Surf will trend up Sunday night and Monday as a medium- period northwest swell arrives. Surf could reach low end advisory levels along north facing shores Monday night and Tuesday as a second, more north-northwest pulse arrives. This swell will then decline Wednesday through late next week. Surf along east facing shores will decline over the weekend, with only small very small surf expected through the upcoming week. Small, medium to long period south swell will continue into next week.
