Looking Ahead

The disturbance generating our recent unsettled weather will continue moving away from the islands, decreasing the threat of widespread heavy rainfall and flash flooding as it distances itself. Trade winds, along with drier and more stable conditions, will move in from the east Thursday and Friday.

Unsettled weather is possible once again over the weekend as a tropical disturbance far southeast of the state could move closer to the islands. The Central Pacific Hurricane Center says “Invest 93C” has a 60% chance of developing into a tropical system over the next 48 hours. Results vary from run to run, but the latest weather models continue to develop a tropical cyclone within a monsoon trough far to the southeast of the state. Models then move whatever develops generally to the northwest toward the state late this week and into the weekend. It is still too early to determine what, if any, impacts will be felt in the islands from this potentially developing disturbance. The weekend forecast is highly uncertain at this point, but rain chances and wind speeds remain boosted somewhat above normal levels.

 

Today

Today we expect easterly winds to begin building back in up to about 15 mph. This will help to make conditions a little less muggy. Partly sunny skies are in the forecast with scattered showers in windward spots and isolated afternoon showers for the leeward side. Hazy skies are expected in the afternoon (see UHSOEST model above). High temperatures between 84° and 89° are expected.

UV index at 12 (“extreme” exposure level)

 

Tonight

Trade winds are expected around 15 mph tonight. Mostly cloudy skies and scattered showers are expected in windward spots. Leeward areas should gradually clear as the night goes on.  Low temperatures from 73° to 78° are expected.
