An upper-level low currently developing over Hawaii will drift
westward and will help bring a stream of tropical moisture
northward across the island chain from east to west through much
of next week.  The moisture axis is expected to first move across
the eastern islands through early next week before becoming nearly
stationary over the western islands for the rest of the week. 
This will likely result in more numerous showers across the
eastern islands early next week followed by periods of heavy rain
possible over the western islands by midweek.  A high pressure
ridge at the lower levels should slowly push drier air from east
to west across the islands through late next week with chance of
rain gradually decreasing toward the weekend.  A mid-level upper
low drifting northwestward to the east and northeast of Hawaii
late next week should have little impacts on the sensible weather
over Hawaii.
