An upper low and associated surface low will meander to the
northwest of Hawaii late this week into the weekend, while a
surface high sets up well north of Hawaii. This combination will
produce breezy trade winds that veer a bit southeasterly. Model
guidance is agreeable that the frontal system associated with the
low (and potentially heavy rain along the cold front) will stay
west of the state, though some enhanced moisture may sneak into
the western islands. To the east of the main system, a generally
northwest-southeast oriented moisture front looks to slowly push
through the state this weekend, though with some timing
uncertainty. Some enhanced showers are possible along the front.
Into next week, breezy easterly trades should prevail as surface
high pressure well north is reinforced by another high. Around
average moisture in place will lead to windward/mauka showers,
with some perhaps spilling into leeward areas. This pattern looks
to persist through much of next week.
