Overnight and morning showers over Oahu cleared Wednesday, but National Weather Service forecasters say Kona winds will bring muggy conditions and more rain is on the way, starting Thursday.

A cold front stalled over Oahu and Kauai overnight, but was expected to dissipate Wednesday, leaving mostly sunny skies, although there may still be some passing showers.

More rain is expected by Thursday night.

Light winds will turn southerly by Thursday. The Kona winds will bring humid conditions and an end to the cool, dry weather experienced earlier in the week. The muggy conditions and daytime heating could also bring afternoon showers to interior and mauka areas.

The southerly winds are likely to spread vog from the Big Island over Maui County, but the vog is not expected to reach Oahu.

Another cold front is expected to move in Thursday night through Saturday. The cold front colliding with the muggy Kona weather will bring rain starting Thursday night.

The greatest chance of heavy rain is on Friday, said Ian Morrison, a meteorologist with the Honolulu office of the National Weather Service.

“We’ll have a chance of brief downpours, but also bouts of sunshine and clear weather,” Morrison said.

Forecasters estimate a 70 percent chance of rain over Honolulu and southern shores of Oahu Thursday night and a 50 percent chance of rain Friday and Saturday. Lows will be in the 60s to low 70s and highs are expected in the low to mid-80s.

Tradewinds should return Sunday.

While winds are light at ground level, a high wind warning is in effect for Big Island summits, which are seeing 30 to 60 mph northwest winds. The winds are expected to subside by Wednesday evening.

A high surf warning is also in effect for north and west facing shores of Kauai County, Oahu and Molokai; and north shores of Maui. A high surf advisory is in effect for north shores of the Big Island. The swell was bringing 25 to 35 foot waves to north shores Wednesday morning. The waves are expected to drop to 18 to 22 feet by Wednesday night, then to 15 to 20 feet Thursday. West shores saw 12 to 22 foot surf Wednesday morning, dropping to 10 to 15 feet through Thursday.
