Good Thursday Morning! We are tracking passing windward and mauka showers within the trade wind flow this morning.
For many windward routes to work, you will likely need to use those windshield wipers and then it clears to leeward sides. The winds are strong enough to push some of the moisture to leeward neighborhoods, so we may see periods of liquid sunshine today.
There is an area of high pressure parked to the northeast of the state over the Pacific Ocean. This will help maintain trade winds into next week with clouds and showers favoring windward and mauka areas. These showers will be more prevalent during the night and early morning hours, and then ease through the day, but we could see some passing showers here and there with plenty of moisture streaming in upstream of us.
Enjoy these classic trade winds, because by Sunday into Monday we may see muggy weather. It is all due to a switch in our winds and an upper level disturbance to our southeast.
Over the weekend, Hawaii Island may see more pop up showers and then it could potentially spread over other islands by the start of the new work week as deep tropical moisture reaches the islands from the southeast entrained by this disturbance.
Until then, expect temperatures for your Aloha Thursday to climb to the mid-80s in many spots with a few 90s across the state. Trade winds will range from 10 to 20 mph.
We are also tracking some south pulses with New Zealand storms pumping up our south shore surf.
Surf along north facing shores will be 1 to 3 feet through Friday.
Surf along west facing shores will be 3 to 6 feet today, lowering to 2 to 4 feet Friday.
Surf along east facing shores will be 2 to 4 feet through Friday.
Surf along south facing shores will be 5 to 7 feet with occasional higher sets today, lowering to 3 to 5 feet Friday
The south swell resulting in near advisory level surf for the south facing shores is forecast to remain unchange through Thursday. A gradual lowering follows and continues into the weekend.
