High cirrus already rolling in from the west. If they’re over the beach by 11:30am, that’s my decision point for driving east. (I’m by the HP ramp in a blue coat, by the way. Feel free to come over and chat.)
What are the confidence intervals for cloud cover parameters of GFS, GEM, etc., at 6-, 12-, 18-, and 24 hours out?
The reason I ask is because I'm trying to build decision points (stay/relocate) into my plans.
