Space Launch Delta 45
A high pressure ridge over the mid-Atlantic states will keep breezy onshore flow over Florida through the week. For Launch Day today, expect winds from the east-northeast at 12-16 kts and scattered cumulus clouds moving onshore. Any isolated light rain showers offshore should dissipate as they move onshore. Therefore, the POV is 10% for the Cumulus Cloud Rule. For the backup day Tuesday, the pressure gradient tightens again, increasing winds to 15-20 kts with scattered cumulus clouds and an isolated shower possible. The POV for the backup day is 20% for the Cumulus Cloud Rule.
