The Wallops Range L-48 hour forecast issued today for the Nov. 6 launch of Northrop Grumman’s 18th resupply mission to the International Space Station continues to be 80% favorable for weather conditions, with the main concern being a slight chance of low-level clouds that may potentially violate cloud ceiling requirements.
Unseasonably warm conditions and tranquil weather are expected through this weekend. A cold front will be located over the Appalachian Mountains Sunday morning, providing light southerly surface flow and upper-level cirrus cloudiness over the Wallops Region. An increase of low-level moisture over the Wallops region due to the light winds may provide some low-level clouds over the Wallops region near launch time. At this time, the primary concern for launch would be a slight chance of low-level clouds.
NASA commercial cargo provider Northrop Grumman is targeting 5:50 a.m. EST Sunday, Nov. 6, for the launch.
