High pressure to the north of Hawaii will continue to support
enhanced easterly trades to windy levels through the early part of
the week. Upper-level ridging aloft will cause low available
moisture and generally dry conditions, which combined with the
winds will lead to fire weather concerns, and the Honolulu Weather
Forecast Office has issued Red Flag Warnings for the fire
potential. However, by Monday-Tuesday a band of moisture
associated with a frontal boundary is forecast to sink south a bit
into Kauai and then Oahu and increase shower chances there,
especially for windward/mauka regions. The mid-upper ridge should
be eroding by Tuesday-Wednesday, while a slight weakening of the
pressure gradient slightly reduces winds to more moderate to
breezy levels. Moist conditions could persist especially over
Kauai. Then by the latter part of the week, breezy trades and
lower heights aloft should promote windward/mauka showers for the
latter half of next week through much of the state.
