@NASA on Twitter:
The updated STS-135 weather forecast remains the same as yesterday with a 30 percent prediction for favorable launch weather.

where are we with the weather situation as far as tanking and launch
Exactly the same as where I said we would be in post #1. No sense in reposting that over and over, as mentioned then I'll let you know if it changes.

Since people worry that I'm too quiet with a critical launch less than 24 hours away, I thought I'd drop by and make those people happy

Looks pretty bad tomorrow. I'm tempted to reduce my 20% of launch to 10%. I don't see anything that would make tomorrow's weather different from today's, and there never was a slot today when we could have launched. No significant change into the weekend.

Sounds like it's time to make cancellable hotel reservations for the next attempt after this weekend. That's next weekend right?

I will certainly not contradict you regarding what you have just said about today's weather and any chances they might launch tomorrow.
My idea is NIL.
I have been thinking that the whole afternoon.
I don't see how anyone would even want to risk spending all that time driving to KSC and back for what will probably be a zero chance of launch.

I don't particularly want to but on the miniscule chance that the weather clears just enough at just the right time it would really be horrible not to be there if they do launch. I'm just bringing a book knowing full well that there's about a 95% chance that I'll spend a lovely drizzly rainy few hours sitting out on the causeway only to have a scrub called during the T-9 minute hold polling.

My wife is a reporter for the CBS Affiliate in Baltimore. They did a full special report on the Launch today and had an entire team of meterologist agreeing that there is almost no chance of a launch this weekend. kinda disappointing, but it is further confirmation of things not looking too good.

so instead of going from a three in ten chance tomorrow to a six in ten chance sunday, we've gone to virtually no chance at all, all weekend long?

I guess the 45th weather squadron will update us tomorrow.

Yes, and also SMG. The trick to this is show up for all tankings and don't get ahead of the forecasts or the forecasters. Also resist the urge to get ahead of MMT decisions.
The ascent flight control team will get an initial briefing when they come on-shift overnight. The crew will also get the standard weather briefing prior to heading out to the pad.

Does anyone know about what time we should get a weather update? I'm on Pacific Time -- trying to figure out how early I should wake up to check for a go/no-go...
Thank you! This thread is so incredibly helpful.

... And for what it's worth, the aviation weather forecast from a few hours ago. Calling for a 5000' foot ceiling (same as STS-134) with added layers above and some scattered cumulonimbus at 2500', plus some thundershowers in the vicinity. What a mess...

TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
800 PM EDT THU JUL 7 2011
FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...
AN ELONGATED LOW PRESSURE SYSTEM LOCATED ABOUT 300 MILES SOUTHWEST
OF TAMPA FLORIDA HAS BECOME A LITTLE BETTER DEFINED DURING THE PAST
FEW HOURS. IN ADDITION...SURFACE PRESSURES HAVE DECREASED OVER THE
EASTERN GULF OF MEXICO DURING THE LAST 24 HOURS. ENVIRONMENTAL
CONDITIONS ARE EXPECTED TO BECOME MARGINALLY CONDUCIVE FOR SOME
ADDITIONAL DEVELOPMENT OF THIS DISTURBANCE. THERE IS A MEDIUM
CHANCE...40 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL OR
SUBTROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES SLOWLY
NORTHWARD OR NORTH-NORTHEASTWARD. REGARDLESS OF DEVELOPMENT...THIS
WEATHER SYSTEM WILL PRODUCE PERIODS OF LOCALLY HEAVY RAINFALL
ACROSS MOST OF THE FLORIDA PENINSULA AND THE EASTERN FLORIDA
PANHANDLE DURING THE NEXT COUPLE OF DAYS.

How ironic. Waiting in Denver Airport for a flight to Orlando. Tstorm has diverted my plane to Albuquerque. Hopefully I can get to Orlando by 4am. DAMN weather!

Virtually no change is not the same as no change.
And the possible tropical system is not a concern either way - the impacts to KSC would be the same whether it develops or not. Rain and clouds.

You might get word of a scrub sooner than that.
