Meanwhile, radar imagery shows some scattered showers over areas west of Kauai due to lingering instability from the low.

Expect these showers, along with the potential for isolated thunderstorms, to continue through this evening.

Elsewhere, a weak pressure gradient over the islands have kept moderate trades and has allowed for weak sea breezes to develop over sheltered leeward areas.

Light showers and limited clouds will impact areas east of the Kauai Channel tonight.

Guidance continues to show high pressure building north of the islands this week as the upper-level low weakens and moves further away from the state.

Expect trade winds to become moderate to breezy on Monday with a return to a more typical summertime trade wind weather pattern as the ridge builds into the region and stabilizes the atmosphere.

Trades look to potentially become moderate to locally breezy by mid to late next week as the high north of the state strengthens.

Clouds and showers will tend to favor windward and mauka areas during this time, with an increase in coverage and intensity during the overnight and early morning hours.
