Wish Rob were here to bounce this off of, but I see some dry air that might move into the Cape area in the next few hours...not sure if it makes any difference, though...

Top image from a visible satellite loop...not sure if it's the most recent in the loop, though...
Second image water vapor from an hour ago...the area of drier air appears to be slowly moving into the area, but we'll see if the precip will move out of the 30 nautical mile circle...
About 70 minutes to the time of the de-orbit burn for the 1st rev.

A few minutes back PAO was relaying information from the weather officer in the MCC about the possibility of showers building up over land when the temperature reaches a certain point. That point was predicted to be 77F; the temperature at the time of the report was 74F, but was expected to reach 77 around the TIG time for the first opportunity (about 9 am local).

When looking at the local radar from milbourne, the heavy storms are about 30 miles East of KSC and moving North.

It doesn't look bad right now, and those storms may not have interfered, but the forecast is for build-up to begin closer to the coast.

Looking at the radar, those rain showers seem to be right over the HAC for a runway 33 landing.

The HAC is not that wide; if that's a shuttle-related display, then the inner circle is probably the 30 n.mi limit.

The temperature has reached the 77F "bingo" temp that was a concern...

I asked this on another thread but got no answer. Anyone know why a landing on rev 195 was not an option? The orbit was in-plane with KSC and it would have been a better choice for deorbit if ground heating was the issue.

Not sure, but I would guess one of the factors is the crew day; they would have had to shift their sleep earlier in the day, and then that may have reduced landing options for Edwards later in the day.
Ground heating is one of the major issues now, but it's not clear if they had any better certainty earlier in the morning for conditions at that time.

Weather at KSC was too unstable during rev 195, could not be sure there would be no precipitaiton within 30 nm of the SLF at the time of deorbit burn
