The first landing opportunity is on the KSC runway at 8:48 AM (1248 UTC). If this landing happens, the ground track is different than usual, making the re-entry potentially visible to much of the continental US.
Unfortunately, the weather forecast is for conditions violating several constraints. Another KSC opportunity exists Monday, and this one also uses the descending node track that would take it over the US. If this is also waved off, STS-131 has several shots at KSC and Edwards on Tuesday.
