Moderate trade winds are likely over the next day or two across
Hawaii, causing potential for showers to be focused mainly over
windward/mountain areas. Then trades are forecast to die down
somewhat by later in the week, allowing for land/sea breezes to
form. Through much of this week, periods of above average moisture
are expected, and upper level troughing should lift inversion
heights beginning around midweek. This will allow for potential
for enhanced clouds and shower coverage, and even perhaps some
thunderstorms. Models show moisture levels may briefly return to
near normal around Saturday before increasing again for early next
week. By around Monday-Tuesday of next week an upper high may
sneak into Hawaii, while trades pick back up to moderate levels.
