Moderate to breezy trade winds can be expected through the weekend and likely into the first half of next week, pushing showers over mostly windward and mountain areas. These showers will be more active during the night time and early morning hours. A mid level and upper level trough could occasionally allow some of these showers to be a little heavier than normal.
Moderate to breezy trades are expected through the forecast period. Low clouds and showers will favor windward and mauka areas. Expect MVFR conditions within showers and VFR elsewhere.
AIRMET Sierra is in effect for mountain obscurations for windward sections and Kona slopes of the Big Island. Conditions should improve over the Kona slopes overnight, while mountain obscurations for windward areas may linger into the morning due to ongoing and upstream showers.
AIRMET Tango is in effect for moderate turbulence downwind of terrain due to the breezy trade winds and will continue overnight.

A surface high will remain nearly stationary north of the state through the week, generating moderate to locally strong trades. Trades will persist through the weekend with minor fluctuations in speeds as the high shifts northeast of the state and gradually strengthens. A Small Craft Advisory (SCA) remains in effect for select waters across the state. The SCA will likely be extended for the typically windier waters around Maui and the Big Island through the weekend as breezy trades hold.
A series of small to moderate, medium to long period south and southeast swells will keep surf along south facing shores elevated into the weekend. A small, long period south swell will continue to fill through tonight and peak Thursday with head high to overhead surf heights at most exposed south shore surf breaks. Additional small pulses of south swell energy arrive on Saturday and Sunday.
Surf along east facing shores will gradually build through Thursday then hold into the weekend as breezy trades persist. West facing shores will remain on the small side with a slight south swell wrap. Surf heights along north facing shores will increase into Thursday due to tiny background northwest swell energy.
Small Craft Advisory until 6 AM HST Thursday for Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters- Kauai Channel-Kauai Leeward Waters-Kauai Northwest Waters- Maalaea Bay-Oahu Leeward Waters-Pailolo Channel.
