Trades will remain pretty light over the next few days, as the
typical surface high to the north of the state is
weakened/displaced by a relatively strong surface low meandering
from around 40N to 35N. Meanwhile a dry airmass is in place, with
precipitable water (PW) anomalies well below average. Thus any
showers should be isolated through Saturday. By early next week
there is a general trend toward higher PWs for the state, as a
surge of moisture moves westward from the Big Island across Maui
and toward Kauai. Meanwhile a weak upper low may hover near/over
Kauai. Both of these features may enhance some rain amounts and
coverage around Sunday-Monday, but nothing too heavy. Mainly dry
conditions are forecast to return around Tuesday and beyond under
an upper ridge, though trades may increase slightly to around
moderate levels.
