Vehicle/Payload:

Delta II / MER-B

Location:

Launch Weather Officer:

Joel Tumbiolo

Synoptic Discussion:

Again, no changes to forecast reasoning.  Deep moisture, which has been confined to south FL, will begin returning northward today.  Weak frontal boundary, which passed to the south several days ago, will return northward.  This boundary marks the transition to the deep moist air mass.  Any low pressure development near the Yucatan will remain well to the west as it moves northward.  By Saturday, once the moisture is in place, normal local triggers (sea breeze, day time heating etc.) with result in the return of showers and thunderstorms.  Main concern for the launch windows will be for remnant cloud cover associated with the showers and thunderstorms.
