    Winds moving around Tropical Storm Ana are coming from the southeast over the main Hawaiian islands.

Kona winds, muggy conditions and afternoon showers are expected across the state Wednesday. But relief, at least for a couple of days, is on the way as cooling tradewinds return by Thursday.

Hilo matched a high temperature record on Tuesday. The 88 degree high at the Hilo Airport tied a record for the date set in 1992.

John Bravender, a meteorologist with the National Weather Service Honolulu office, said it’s possible, but not likely that Wednesday will bring another record heat day.

“We could see more widespread sea breezes today,” he said. “The onshore winds should help keep temperatures from getting excessively warm. But we’ll still be humid.”

The sea breezes, which carry moisture from the ocean over land, will add to the muggy conditions, making it feel warmer, while keeping the actual temperature slightly lower.

In addition, an old weather system moving over the islands is bringing a greater chance of showers Wednesday through Wednesday night.

The forecast for Honolulu and south shores of Oahu calls for a 40 to 50 percent chance of rain with light southeast winds and highs between 82 and 88 degrees.

The Kona winds are being generated, in part, by winds moving around Tropical Storm Ana, more than 500 miles west of Lihue.

There’s a chance of scattered patches of vog being blown over some islands, but most of the volcanic haze should remain offshore, Bravender said.

Cooling tradewinds should return by Thursday morning as high pressure moves north of the state. However, the trades are expected to diminish over the weekend, bringing more humid weather and afternoon showers in leeward and mauka areas.
