Another day of a hybrid trade and land/sea breeze pattern seems
possible for Monday, as troughing overhead provides a lessening
inversion for scattered showers. But by Tuesday and beyond, this
trough will move quickly west giving way to ridging aloft and
promoting more stable conditions. At the surface, high pressure
northeast of the state drifting west will increase the pressure
gradient and lead to strengthening trades to breezy or perhaps
strong levels, lasting through late week before somewhat weakening
for the weekend. Meanwhile, what is currently Tropical Storm Irwin
in the eastern Pacific is now forecast to move more slowly
westward while weakening, and model guidance no longer shows even
a remaining trough or its moisture to approach Hawaii.
