Operational models and ensemble data continue to advertise a very
stable pattern setting up for Hawaii. A rather strong 588dm upper
ridge building across the state will be in the forecast picture
through the upcoming weekend into much of next week to deliver a
beautiful stretch of weather. Expect more traditional light to
moderate trades with possible windward showers. By early next
week, ensembles and operational guidance capture upper dynamics
digging upstream in the mid-latitudes and potentially closing off
aloft between 20-30N and 170-180W. Despite this feature to the
west, the ridging appears to hold on but brisk southeasterly flow
across the islands is possible with minimal shower activity.
