.DISCUSSION...
Breezy trades continue through the week, likely strengthening this
weekend. However, dewpoints and subsequent RH values will remain
elevated throughout this time. The inversion hovers around 6kft
this morning but will rise over the eastern end of the state as
deeper moisture entrained in the trades works into the area. Heavy
rain possible over the Big Island possibly Maui later in the week.
