Breezy easterly trade winds are likely through the weekend and
into the first part of next week, as elongated surface high
pressure stays in place well north of Hawaii. Meanwhile aloft,
weak troughing possibly forming a closed upper low atop the state
this weekend could allow for some minor instability to develop,
increasing potential for showers. Showers should focus in
windward/mauka areas due to the trades. Models show above normal
moisture (precipitable water values) coming into the state
Monday-Wednesday as well.

By the latter half of next week, the elongated surface high is
likely to split north of Hawaii and decrease the pressure
gradient, lessening the trades and perhaps allowing for a land/sea
breeze pattern to set up. A somewhat drier pattern looks to
develop as well, as mid-upper heights rise.
