The Wednesday, Feb. 16, Wallops Range forecast predicts 75% favorable weather for the Saturday, Feb. 19, launch window of NASA commercial cargo provider Northrop Grumman’s Antares rocket and Cygnus cargo spacecraft.
The primary concern for launch at this time is strong southwesterly ground winds.
A strong upper-level shortwave digs out of the Great Lakes region Saturday morning and moves through the northern mid-Atlantic region early Saturday afternoon. This will push a secondary cold front across the Wallops area near the time of T-0 on Feb. 19. Surface winds will increase out of the southwest Saturday morning and there is a chance for a few cumulus clouds to develop to our northwest prior to the launch window.
