Guidance overall indicates that the combination of a Pacific
surface high well to the north of Hawaii and a tropical
disturbance passing to the south tightened up the recent pressure
gradients over the state to produce windy trades. This plus a
relatively dry pattern with normal to below normal moisture levels
led to the recent issuance of Red Flag Warnings for leeward
portions of many of the islands and offshore small craft
advisories. As the tropical low pressure moves west and the
surface high weakens into the weekend, trade winds are forecast to
moderate. The relatively dry pattern is forecast to last through
early next week, limiting shower coverage, but some windward and
mauka showers are possible under a general weakness aloft. There
is some chance for tropical moisture to increase by
Tuesday/Wednesday that could fuel a bit more activity, but drier
trade flow may re-emerge later next week.
