After Tropical Storm Calvin passes by the Big Island early
Wednesday, conditions should return to a more typical trade wind
flow pattern across Hawaii for the end of the week and into the
weekend.  The main subtropical high will be centered well north of
the state near 35 degrees north, and a larger surface high near
45N/170W through Friday.  The subtropical high should remain
anchored in place through early next week, with the center of the
high drifting some to the east based on the latest ensemble means.

Lingering showers from the weakening tropical storm can be
expected through early Wednesday night with normal trade wind
enhanced showers expected for the remainder of the forecast
period, with flow generally out of the east-northeast most days.
