Trade winds should gradually strengthen through this weekend and
drier air re-establishing across much of the state into early next
week in a more stable upper pattern. Any showers should be limited
to windward terrain areas as high pressure builds and bridges to
the north of the islands. The guidance continues to suggest that
upstream upper ridge amplification over the west-central Pacific
may allow a rounding upper trough to dig southeastward towards
Hawaii mid to later next week. This could bring a cold front
towards the islands later next week increasing moisture chances
and disrupting trades.
