The subtropical high will remain in place to the north of the
state around 30-35N through the end of the week, and then shift to
the northeast and weaken slightly this weekend. 
East-northeasterly trade winds will persist, though winds may
decrease slightly over the weekend and veer more to the east or
east-southeast as the high retreats weakens.  This pattern will
favor precipitation chances each day for the favored east-facing
terrain, and conditions will remain mainly dry for southwestern
portions of the Islands. A low pressure system is forecast to
develop to the northwest on Friday and bring a trailing frontal
boundary towards the far northwestern Islands next week, but the
front will likely be blocked by the subtropical ridge and remain
northwest of the state, keeping the most impactful weather well
offshore through at least the middle of next week.
