Good Thursday morning!
Our high pressure fan to the distant north-northwest will support gusty trade winds today, with winds diminishing Friday and Saturday as an area of low pressure develops north of the islands.
The trade winds will deliver showery low clouds that will favor windward areas, although some showers will spread to leeward sections of the smaller islands.
Highs today will be below average in some spots ranging from 77 to 85 degrees.
Then it will feel even more like Autumn as we head into the weekend (at least for Hawaii's standards).
Winds will diminish, and then they will also become northerly, and these north winds will spread a cool air mass over the islands over the weekend through the middle of next week, while also delivering clouds and showers that will tend to focus over north-facing slopes and coasts.
Cooler weather will be the more noticeable change across the islands over the weekend through the middle of next week, as the airmass overspreading the islands will have origins from the far north Pacific and will be brought in on northerly winds.
Dew points are forecast to drop into the upper 50s to around 60 late Saturday and Saturday night in the wake of a weak cold front moving through from northwest to southeast. This will result in quite comfortable weather across the island chain Sunday through the middle of next week.
Let's talk swells! Surf will remain up along north and east facing shores through the upcoming weekend and next week as overlapping north-northeast swells continue to impact the islands. More significant northerly swells will be possible Sunday through next week, which could lead to advisory level surf along north facing shores Sunday into Monday, then warning level surf on Wednesday.
A slight increase in surf along south facing shores will be possible over the weekend as a south-southwest swell fills in.
