If you've been missing the trade winds, good news, they will be returning later this weekend. For now, that means warm, moist, and somewhat unstable southwesterly winds to continue across the state today ahead of a cold front northwest of Kauai.
We are tracking several bands of showers ahead of the front that has mostly stayed over the channels. Within the 6 am and 7 am hours, some of this rain will be pushing over parts of Maui county.
What can we expect for the rest of the day? By late this afternoon into the evening, this front will push southeastward down the chain. At times the southwest winds can be gusty. During the afternoon on Hawaii Island there may be another round of thunderstorms that fire up near Puna and Volcano after daytime heating.
Our weather models show the front hanging off of the Garden isle begin to slide down the island chain this evening, spreading increased showers as it goes and leaving a trade flow behind it-- filling in. As far as timing, this front will likely reach Hawaii Island on Friday into Saturday before stalling. Then the entire island chain will likely lie within trade flow by Saturday into Sunday.
As the winds shift, we can expect the remnant moisture along this front to keep the trades rather showery through the weekend and into next week. Mainly impacting windward and mauka neighborhoods but at times the expected swift trades can push moisture leeward for passing showers.
Surf is on the rise. We are tracking a series of north-northwest swells. The first one is expected Friday night into Saturday. Then a north-northwest will fill in Monday through Tuesday, and potentially become reinforced by Thursday. During this period, possibly an advisory-level swell will bring bigger surf along north and west facing shores into Tuesday. Also, as the trades pick up to gusty levels, east shores will see elevated surf and likely choppy conditions.
Wishing you a wonderful Thursday.
