Sunday, there is a north to south band of clouds and showers trailing Lester that will bring more showers late morning – including a slight chance of a thunderstorm for the smaller islands. This band will continue westward finally clearing Kauai County by mid Monday morning. Daytime heating could also lead to afternoon thunderstorms.
Well ahead of the band, a convergent southerly wind flow that covers Maui County and Oahu, has resulted in isolated to widely scattered heavy showers over the waters. One showers that formed in the Alenuihaha Channel, has ended up over the slopes above Hana Maui, prompting a Flood Advisory for that section of Maui earlier this morning.
By this time tomorrow, all islands will be under stable, moderate to locally strong trade wind regime. Showers will be present with this flow, favoring the windward and mountain areas. The frequency of the showers will highest during the nights and mornings. The strength of the trades will be switching between moderate and moderate to locally strong during the new work week. An upper level disturbance may enhance some the trade showers during the second half of the week.
As Lester pulls farther away from the islands, trades will be returning to the islands Monday. The trades are expected to stay with us through the rest of the new week.
Mostly cloudy with scattered showers becoming more likely in the afternoon. Possible locally heavy rain and a slight chance of thunderstorms are also in the forecast. High temperatures from 83° to 88° but feeling warmer due to the humidity. Southeast winds up to 10 mph.
