.SYNOPSIS...An upper ridge over the area will bring dry weather 
to the park today into Friday morning. A frontal system will 
move quickly through the park Friday night, followed by showers 
on Saturday. A stronger upper ridge has the potential to bring 
the longest stretch of dry weather this month beginning Sunday and
continuing into the middle of next week.

.IMPACTS...Strong winds in alpine regions on the mountain, 
including the Muir snowfield, will make it difficult to move

into Saturday. A high level of skill and experience in alpine 
terrain, including use of GPS, is recommended for navigation and 
camping in these conditions.
