.... Update...

Weather still looks on track the same as discussed in an earlier email.

A minor cut off low 500mb moving NW along coast from LA area will help
to destabilize airmass over Sierras. But, with the dry airmass that
means just lots of high based cu 15-17k msl based from the Tehachapi
Mtns north to Lake Tahoe and Truckee. Best route is into S or SE
Oregon... probably along Cascades north of Klamath Falls. it will be
"blue" north of about Susanville.

Take a look at DrJack, XCSkies and Topmeteo... also modelsoundings in
the folder:

Launch time at Mt Valley will probably be around 1130am... perhaps a tad
earlier.... to about 8500msl. Winds at Ridge Top Level will probably be
SE 10kts. Surface winds either light W or SE... perhaps switching during
launch.

Overall... an outstanding day for flights north.
