A slow moving front will move through Kauai later today and through Oahu tonight. Light winds ahead of the front will allow for daytime sea breezes in most areas from Oahu eastward, while the winds will pick up out of the north on Kauai later this morning and Oahu tonight behind the slow moving front. Moisture ahead of the front along with an upper level disturbance moving overhead will keep conditions unsettled, with scattered showers and temporary MVFR cigs/vsbys possible across the entire island chain through the next 24 hours. The best chances for reduced cigs/vsbys will be this afternoon and this evening as showers develop as a result of daytime heating. Additionally, MVFR cigs/vsbys are expected to become more widespread across Kauai later today and Oahu tonight along and behind the slow moving front, with the most unsettled conditions expected over windward and mauka areas.
AIRMET Sierra remains in effect for mountain obscuration across northwest thru northeast sections of Kauai. These conditions will likely remain in place through much of the day. The AIRMET will likely need to be expanded to include the interior of some of the other islands this afternoon.
