At 6 a.m., the relative humidity at Honolulu International Airport was already 82 percent.

But hang on, the National Weather Service forecast calls for a change to occur when a cold front approaches Kaua'i late tomorrow.

The winds will become more southerly and showers will increase ahead of the front, which is expected to slide down the rest of the island chain by Sunday and stall out by Sunday evening.

Moisture from a disturbance far southwest of Kaua'i could move toward the islands late Sunday night or early Monday morning.

Here's a more detailed look at what the next few days are expected to bring:
