Starlink 4-19 - L-1 Day

Low rain chances and above average temperatures will continue to be the story for the next couple of days as a strong mid to upper level ridge persists over the southeastern US. Tomorrow, a weak pressure gradient at the surface will bring light onshore winds to start the day, allowing the east coast sea breeze to form and push inland by the afternoon. While a very brief, weak onshore moving shower cannot completely be ruled out, overall launch conditions will be favorable for tomorrow. The only concern is the Cumulus Cloud Rule. On Saturday, a surface boundary will push into the southeastern US. The boundary itself will not reach Central Florida by midday, but it will shift winds west/southwesterly and increase moisture in the area. Shower and storm chances will be higher on Saturday compared to the rest of this week, but most of the activity is still not expected near the Spaceport until after the launch window. However, models have trended the front a bit faster and farther south compared to the last several days, hence the slight increase in the Probability of Violation. The primary concern remains the Cumulus Cloud Rule.
