Friday's warmth supports thunderstorm activity south of the mountain and southerly winds may steer these storms over the mountain. Climbers should be prepared for changing conditions including snow squalls Friday afternoon and evening. The Bristol Bay storm system shifts southeast across the Alaska Peninsula over the weekend, but it stays far enough away that winds stay light. Confidence in cloud and precipitation chances is low, but the hit and miss showery regime appears to continue. && $$ EK Jun 26
