HONOLULU (KHON2) - A high pressure far northeast of the state will help to maintain breezy trade winds through the next couple of days. More batches of moisture caught up in these trades will periodically filter in across the island chain, with clouds and showers generally focusing across windwa rd and mauka areas. An upper-level low will move over the state from the west starting late tomorrow and remain there through mid week, bringing some instability aloft, which may help to enhance windward showers at times. A strong low pressure system to the far north will displace the ridge to bring it closer to, or over, the island chain by mid week. The proximity of this ridge and the approach of a front/trough from the northwest will bring lighter southeast winds across the area, allowing land and sea breezes to expand in coverage and dominate the local weather regime. This will lead to mostly clear nights and mornings giving way to afternoon clouds and showers over interior/leeward areas. An upper level trough will dive southeast across the Central Pacific and move overhead by Wednesday evening, bringing cooler temperatures aloft. The instability associated with this feature combined with pockets of moisture moving across the island chain on the southeast flow may lead to enhanced diurnal showers with brief heavy downpours over island interiors during the day, particularly on Thursday and Friday. Small Craft Advisory until 6 PM HST Monday for Maalaea Bay, Pailolo Channel, Alenuihaha Channel, Big Island Leeward Waters, Big Island Southeast Waters. ...read more read less
