Breezy easterly trade winds are likely late this week 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. The forecast for the latter half of next
week is more uncertain, but there is a general signal for
weakening high pressure to the north and thus decreasing trades.
