A cold front progressed through most of the Hawaiian Islands on
Wednesday and will push east of the Big Island by early Thursday.
The front has brought in a drier airmass with few if any showers
for the next couple of days. Additionally, lower dewpoints will be
in place through late week, which will also allow minimum
temperatures to fall below normal. The front has also caused some
strong westerly winds, which are forecast to gradually decrease
today into Friday, and remain on the weaker side into the weekend
and early next week given a weak pressure gradient at the surface.
A land/sea breeze pattern may set up over the weekend, with some
interior showers as moisture levels return closer to normal.

By Monday and beyond, a frontal boundary looks to set up north of
Hawaii, drawing some southerly winds and more moisture into the
state. There is uncertainty in the location of the front and its
meandering. But by around midweek it appears possible it could
sink south enough to focus moisture at least across the western
islands for a wetter pattern, so this will continue to be
monitored.
