The prevailing flow over the Central Pacific favors various levels
of subsidence and dry conditions followed by periodic but mainly
dry cold frontal passages over the islands for the next week. The
longwave pattern shown by the agreed upon consensus is for a
retrograding upper trough over the Gulf of Alaska. Reinforcement
of the trough should allow for a cold front to move near the
islands and dissipate by Friday, while more substantial cold
fronts pass through the islands next Monday and Thursday. The
widespread antecedent subsidence before the cold fronts arrive
combined with their rapid approach support mainly dry conditions
for the next week. Accompanying the fronts will be varying wind
speeds and wind directions.
