HONOLULU (KHON2) – As this plume of moisture continues to increase over the Big Island this evening and tonight, we should see an increase of rain mainly over windward Big Island tonight.
Stable conditions aloft, should keep rainfall intensities at moderate levels and if anything the rainfall should be beneficial to our ongoing drought conditions.
For Sunday, we should see the trough continue to drift westward and will likely bring an increase of moisture to the rest of the state.
With the lighter trade winds in place, localized sea breezes should develop across select leeward areas by mid day.
Sea breeze convergence should lead to an increase of clouds and scattered showers Sunday afternoon across interior and leeward areas.
For areas that do not see any shower activity, with the increase in humidities, temperatures will feel muggy.
There is good model agreement with high pressure building back in to the northeast of the state early next week, which should allow the trade winds to strengthen back to moderate to locally breezy levels by midweek.
At the same time, a drier airmass is expected to return to the islands.
