USSF-12 - L-2 Day

Surface high pressure over Bermuda with the ridge axis remaining to our north this week will bring us east to southeast flow locally through Friday. This favors overnight and morning showers, with drier evenings. For MLP Roll day Wednesday, expect light winds in the morning picking up to 10-15 kt in the afternoon from the east with widely scattered showers possible. For launch day Thursday, higher than average moisture content and a weak surface wave moving westward into Florida will increase morning shower chances and bring isolated storms extending until as late as mid-afternoon before shower coverage reduces by the evening for the launch window For backup day Friday, a similar setup is expected with increased moisture and still moderate onshore flow from the southeast. The primary weather concern for both days is the Cumulus Cloud Rule.
