The trades are forecasted to bring passing showers to windward areas with a few reaching leeward locations on the smaller islands. The leeward Big Island will see afternoon clouds and some showers. Trades are expected to drop to moderate levels for the weekend as an old frontal cloud band moves south over the islands during the weekend and brings increasing showers.
