Here's the weather forecast for SpaceX's 2nd astronaut launch attempt on Saturday
Space.com
https://www.space.com/spacex-demo-2-backup-launch-weather-forecast.html (https://www.space.com/spacex-demo-2-backup-launch-weather-forecast.html)
SpaceX called off the launch of its Crew Dragon spacecraft from Kennedy Space Center in Florida about 17 minutes before the planned liftoff due to unfavorable weather conditions. The crewed test flight, called Demo-2, is now slated for a second launch attempt on Saturday (May 30), with a backup launch window on Sunday (May 31). The Saturday launch attempt would be at 3:22 p.m. EDT (1922 GMT), while the Sunday attempt would lift off at 3 p.m. EDT (1900 GMT).
In its latest launch weather forecast, issued today at 8:30 a.m. EDT (1400 GMT), the U.S. Air Force's 45th Space Wing predicted a 60% chance (https://www.patrick.af.mil/Portals/14/Weather/Falcon%209%20Dragon%20Crew%20Demo-2%20L-2%20Day%20Forecast%20-%2030%20May%20Launch.pdf?ver=2020-05-28-092610-563) of unfavorable weather conditions that would prevent SpaceX from launching the Demo-2 mission on both Saturday and Sunday.
Their forecast cites precipitation, anvil clouds and cumulus clouds as "primary concerns" on Saturday, and adds thick clouds to the list of possible weather violations on Sunday.
The 60% chance of a weather violation is slightly worse than the weather forecast SpaceX and NASA were facing with the first launch attempt. The 45th Space Wing had predicted a 50% chance of bad launch weather on Wednesday, which was much better than the 70% chance it had predicted just a few days before the planned launch.

NASA’s SpaceX Demo-2: Countdown Update
NASA by Anna Heiney
https://blogs.nasa.gov/commercialcrew/2020/05/30/nasas-spacex-demo-2-countdown-update/ (https://blogs.nasa.gov/commercialcrew/2020/05/30/nasas-spacex-demo-2-countdown-update/)
The countdown continues to go well for today’s planned 3:22 p.m. EDT launch of NASA’s SpaceX Demo-2 flight test to the International Space Station. At Kennedy Space Center’s Launch Complex 39A, the SpaceX Falcon 9 rocket is powered on and the launch team is pressurizing gaseous storage vessels onboard. Meanwhile, the Crew Dragon spacecraft is being prepared for NASA astronauts Douglas Hurley and Robert Behnken to board later in the countdown. Weather remains the big question for today; the chance of favorable conditions at launch time remains 50%.
We’re standing by to see the crew leave the suit room in Kennedy’s Neil Armstrong Operations and Checkout Building and wave to their family, friends and support team members before the ride to the launch pad.

Why are they doing "early" PM launch times? Seems like Apollo missions launch times were A.M. Maybe that was Apollo 11.

Lot of convection east and west of the launch site. And a lot more than before the scrubbed launch mid week. I am not too optimistic.

The launch time is dictated by the trajectory path required for the mission. In this case, for docking with ISS.

That's a more optimistic look than my outlook, and they do have the direct met data. OTOH, I have lived my entire life near the Gulf Coast, and know how weather can change rapidly with a few cumulus clouds and unabated summer heat.
Fingers crossed!!!!!

NASA Astronauts pilot SpaceX Crew Dragon manually during their voyage to the Space Station
TESMANIAN by Evelyn Arevalo June 01, 2020
https://www.tesmanian.com/blogs/tesmanian-blog/pilot-mission (https://www.tesmanian.com/blogs/tesmanian-blog/pilot-mission)
SpaceX formed a partnership with NASA under the agency's Commercial Crew Program which funded Crew Dragon's development. SpaceX performed its first crewed mission on May 30, a Falcon 9 rocket lifted off from historic Launch Complex 39A at the John F. Kennedy Space Center in Cape Canaveral, Florida. NASA Astronauts Robert “Bob†Behnken and Douglas “Doug†Hurley were launched into orbit aboard the Crew Dragon spacecraft. The successful deployment returned human spacecraft capabilities to the United States. NASA had not launched astronauts from American soil since 2011.The mission is called Demo-2, it is a demonstration test flight to test out all of Dragon’s capabilities. The astronauts named the first SpaceX Dragon to carry humans - Endeavour. "We both had our first flights on Shuttle Endeavour, and it just meant so much to us to carry on that name," Hurley shared.
Crew Dragon is capable of operating autonomously, however, during Demo-2, Behnken and Hurley performed the first manual test flight. Both, have extensive experience as military pilots and performed two Space Shuttle missions to the orbiting laboratory. Hurley was pilot on two space shuttle missions, including the last shuttle flight in 2011. Hurley is a veteran Marine Corps test pilot, and Behnken was an Air Force flight test engineer before NASA selected them as astronauts. They helped SpaceX design the spacecraft’s interface and features. “Ultimately they decided on a touchscreen interface,†Hurley said. “Of course, growing up as a pilot my whole career, having a certain way to control the vehicle, this is certainly different. But we went into it with a very open mind, I think, and worked with them to kind of refine the way that you interface with a touchscreen and the way that your touch is actually registered on the displays in order to be able to fly it cleanly and not make mistakes touching it, and potentially putting in a wrong input, those kinds of things.â€
Dragon’s operation is very different than the Space Shuttle, its cockpit had over one thousand switches, buttons and joysticks to operate the systems and spacecraft, pictured above. Dragon’s control system is a trio of sleek touchscreen computers, the craft only has a few buttons that are to trigger emergency operations. The SpaceX spacesuit's gloves are specially designed to function with the touchscreens. Dragon's displays provide real-time information on anything from its position in space, to possible destinations, and the environment onboard. A simple tap on a screen is capable of igniting Dragon’s integrated space thrusters to slightly alter the craft's direction. Both astronauts collaborated with SpaceX to design interior controls and display features in the Dragon spacecraft, "Every display and every procedure that is presented to crews in the future is going to have multiple items...that are our inputs," Behnken shared.

How Crew Dragon compares to flying on space shuttle from the first NASA astronauts to do both
Click Orlando by Emilee Speck 6/1/2020

After becoming the first NASA astronauts to launch from Florida in nine years, astronauts Bob Behnken and Doug Hurley are reflecting on how flying in their previous spaceship, the space shuttle compares to their new ride built by SpaceX’s the Crew Dragon spacecraft.
Hurley and Behnken launched from Kennedy Space Center on a SpaceX Falcon 9 rocket Saturday at 3:22 p.m. after Crew Dragon separated from the rocket it took about 19 hours for the spacecraft to arrive for docking at the International Space Station. During that journey, traveling at 17,500 mph at times, the test pilots and astronauts got to be the first to try out the brand new spacecraft.
On Monday, in a call from the space station, both astronauts and their fellow station crew member NASA astronaut Chris Cassidy reflected on how it felt and looked to fly in Crew Dragon and see it approaching the ISS.
What it was like launching on Falcon 9
Both Hurley and Behnken said launching on Falcon 9 was very different than the space shuttle. Hurley described Falcon 9 as a “pure flying machine.â€
“The Falcon 9 is a liquid-fueled rocket. Remember shuttle had solid rocket boosters to start with, those burned very rough for the first two and a half minutes," Hurley said. “The first stage with Falcon 9 with the 9 Merlin engines and roughly the same amount of time and it was a much smoother ride.â€
Hurley said he and Behnken both felt the difference when the Falcon 9 first and second stage separated during launch.
“At that point, we go from roughly 3 Gs to 0 Gs ... when that Merlin vacuum engine fires then we start accelerating again for the next 5-6 minutes until we achieve orbit so totally different than shuttle,†Hurley said. “It was smooth and got a little rougher as Bob had mentioned before with the Merlin vacuum engine and it’ll be interesting to talk to the SpaceX folks to find out why it was a little bit rougher ride on second stage than it was for shuttle on those three main engines.â€

Saturday's launch to the ISS is only the first half of NASA's SpaceX Demo-2 test flight.
The Crew Dragon will next have to safely ferry the astronauts back to Earth.
The exact duration of the mission is yet to be determined but the Demo-2 astronauts will remain in orbit between one and four months.
This particular Dragon can stay docked to the ISS for 110 days and fully operational Dragons will stay for nearly twice as long.

NASA anticipates August return for Hurley and Behnken
Spaceflight Now by Stephen Clark June 9, 2020
https://spaceflightnow.com/2020/06/09/nasa-anticipates-august-return-for-hurley-and-behnken/ (https://spaceflightnow.com/2020/06/09/nasa-anticipates-august-return-for-hurley-and-behnken/)
SpaceX’s Crew Dragon spacecraft will likely return to Earth in August to wrap up a test flight to the International Space Station with NASA astronauts Doug Hurley and Bob Behnken, a senior space agency official said Tuesday.
The exact schedule for Hurley and Behnken’s return to Earth will hinge on several factors, such as the performance of their Crew Dragon spaceship, the progress of their work on the space station, and weather conditions in the capsule’s landing zones in the Atlantic Ocean and the Gulf of Mexico, according to Ken Bowersox, the acting associate administrator for NASA’s human exploration and operations mission directorate.
Bowersox said Tuesday that the Crew Dragon’s Demo-2 mission — the first SpaceX mission to carry astronauts — is proceeding as planned, and the crew capsule is performing well since its launch on a Falcon 9 rocket May 30 from the Kennedy Space Center and docking with the space station one day later.
