Artemis I - L-2 Days

No significant changes have been made to the forecast. An unsettled weather pattern will continue across Central Florida today as a weak trough to the north keeps very light steering flow out of the south to south-southwest. This will favor another stormy afternoon across the Spaceport with convective activity decreasing after sunset. On Sunday, a pattern shift back to south-southeast flow is expected, which should decrease the areal and temporal coverage of storms along the Space Coast. This flow regime will remain in place for the opening of the initial launch window Monday morning. While the overall lightning threat seems low, this onshore flow regime will promote scattered showers across the Atlantic waters through the launch window. As a result, the primary weather concerns for a Monday morning attempt will be the Cumulus Cloud Rule, Surface Electric Fields Rule, and the Flight Through Precipitation constraint.
