More heat, humidity forecast, but tradewinds on the way

HONOLULU (HawaiiNewsNow) - Another day of hot and humid weather is in the forecast for Sunday, but light trade winds are expected to build for the first half of the new work week.

Winds will remain light and variable for one more day, allowing for afternoon sea breezes. There's a bit more moisture around the islands, so there's a higher possibility of interior clouds and showers during the afternoon.

There's also a disturbance off to the south of the Big Island of Hawaii. That's going to be a source of deep tropical moisture, so don't be surprised if there are some heavy showers and thunderstorms over southern areas of the Big Island.

Temperatures may match Saturday's record highs. Kahului's high of 95 was a new record, while the thermometer hit 90 in Hilo, tying a record high for the date.

What's happening is that a surface trough near Oahu and a weak frontal boundary near Kauai have lightened the trade winds. The disturbance mentioned earlier is also a source of moisture to fuel the humidity and showers.

Some relief is on the way. Forecast models point at trade winds increasing starting Monday. They're still going to be a bit light, and humidity levels will still be on the higher side, but conditions should finally be a little more comfortable.
