NASA Crew-6 - L-1 Day

A low pressure system is moving through the Great Plains as high pressure builds back into Florida and the ascent corridor. Through the day Wednesday, this low pressure area will move into the Ohio Valley and strengthen as the high pressure ridge slides east of the ascent corridor. By launch time early Thursday morning, the ridge will extend from South Florida to Bermuda, creating moderate winds in the staging area due to the pressure gradient between the ridge and a low-pressure area. Launch weather remains favorable with only a very slight chance of a shower developing over the pad at launch time. Through the day Thursday and Friday, a stronger low pressure area will develop in Texas and move steadily across the U.S., progressively enhancing the winds and cloud cover from Florida through the Mid-Atlantic States. The primary weather concerns for both the 24 and 48 hour delay attempts will be continuously increasing winds in the staging area and to a lesser degree the spaceport.
