HONOLULU (HawaiiNewsNow) - The National Weather Service has cancelled the flash flood watch that was posted for Kauai, Niihau and Oahu, as conditions began to improve over the state Tuesday afternoon.

Fewer showers were showing up on satellite and radar imagery, indicating that a trough to the west of the state is weakening. That should allow for more gradual improvement and the return of tradewind weather for the end of the year.

While the system responsible for the wet weather is weakening, there is still enough moisture in our atmosphere present to fire up isolated moderate to heavy showers overnight, mainly near Kauai. The rest of the state could see moderate scattered shower activity, but forecasters said their times and locations would be hard to pinpoint

Winds should remain light through Wednesday with local land and sea breezes for many locations. Trades are expected to gradually return Thursday as high pressure builds to the north and northeast of the state, just in time to blow away New Year's Eve fireworks smoke. More sunshine and blue sky will return, along with windward and mauka showers, by Friday.
