HONOLULU (KHON2) – High pressure to the NE will weaken tonight and shift south through Tuesday, allowing the local pressure gradient to relax.

Weaker winds across the western half of the state will allow for a land/sea breeze regime to dominate, with afternoon clouds and showers forming over a few leeward and interior areas and clearing at night.

The eastern half of the state will see more of hybrid tradewind and land/seabreeze pattern with showers favoring windward areas overnight and leeward slopes of the Big Island each afternoon.

Wednesday through Thursday, winds will veer more southerly over the western half of the state and ESE over the eastern half as a front approaches from the northwest and the surface high shifts eastward.

The ESE flow may also allow island plumes (downstream convergence from island terrain) to bring showers to leeward areas at times.

However, even as the boundary layer moistens a bit with small pockets of moisture riding in on the lighter ESE flow and dew points increase a tad, mid level ridging will strengthen over the area and help to suppress shower activity…so mostly dry and stable conditions should continue through midweek.

The tail end of a front may pass just to the north or move through portions of the state late in the week.
