Detailed Forecast
Synopsis
Relatively dry moderate trades will continue through the forecast period. Clouds and showers will remain focused over windward and mauka areas during the overnight and early morning hours through this time.
Discussion
Very little change in prevailing conditions is anticipated for the balance of the forecast period. Moderate trades will demonstrate occasional minor fluctuations in intensity while upstream moisture remains on the drier side. Current satellite analysis indicates limited moisture characterized by PWATs on the order of one inch or less extending well upstream. Global model consensus further suggests that dry air in the mid-levels will further serve to reinforce existing stability. As a result, a relatively dry trade wind pattern will support quiescent conditions for at least the next 5 to 7 days. The greatest coverage of clouds and showers will be focused over windward and mauka areas mainly overnight and in the early morning hours.
Aviation
A weak high pressure ridge far north of the region will continue to produce moderate trade winds. Lighter large scale winds over each island will allow localized sea breezes to develop along terrain sheltered western slopes.
An upper level disturbance just northeast of the Hawaiian Islands will will help to destabilize the atmosphere and keep scattered showers in the forecast for today. Trade winds will be strong enough to favor windward and mountain areas in the overnight hours. Wind convergence between the background trade flow and the west side sea breezes may create isolated shower bands over leeward and interior sections of each island this afternoon. A few areas may briefly see MVFR conditions in moderate showers, otherwise VFR conditions will prevail.
No AIRMETs in effect and none are expected.
Marine
High pressure north of the state will keep moderate trade winds in place through the weekend, with only minor fluctuations in strength. Winds and Seas are expected to remain below Small Craft Advisory thresholds throughout the forecast period.
A series of overlapping south swells will keep south shore surf near seasonal levels through the work week, with surf dropping to slightly below normal levels over the weekend into early next week. East shore surf will remain very small during the next 7 days. Surf along north facing shores will remain nearly flat through Saturday, with a small north swell giving north shore surf a slight boost Sunday through early next week.
