A relatively dry post-frontal airmass remains settled across the
Hawaiian Islands with high pressure bridged to the north of the
state. Models and ensembles still reasonably agree that rainfall
will be limited this weekend. Activity should be primarily
confined to favored windward terrain, especially over the Big
Island, in breezy trade flow over the next few days. The approach
of an amplified mid-upper level trough energies from the northwest
should act to relax trade support over the islands and allow
moisture to gradually rebound early next week. Main system passage
aloft along/north of the state Tuesday/Wednesday should also force
a well defined surface cold front with some organized showers
through the islands. This will be followed by a return of moderate
post-frontal trade flow extending into next weekend as supporting
high pressure becomes re-established to the north of the state.
Forecast spread and uncertainty is below normal in this weather
pattern over much of the next week, so a near composite guidance
mass field solution seems reasonable.
