Launch day probability of violating launch weather constraints: <10%
Primary concern(s): Liftoff Winds
Delay day probability of violating launch weather constraints: 10%
Primary concern(s): Cumulus Cloud Rule

No change to launch weather forecast.

Less than a 10% chance of violating Falcon 9 launch weather commit criteria on Monday.

10% chance of violation in the event of a 24 scrub/delay to Tuesday.
