Ice retreating ahead of schedule as clear skies have led to plenty of diurnal warming. Brief southward advancement of ice may occur during the overnight hours, but the overall trend should see ice continue retreat northward into the weekend largely due to the warmer temperatures as winds will remain generally light. Please note that ice motion in Cook Inlet is highly influenced by tides. && Riedel
