An upper-level low currently developing over Hawaii will drift
westward and will help bring a stream for 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 and periods of heavy rain possible
over the western islands by the 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
decreasing toward the weekend.
