The highlights from the 45th Weather Sqdn.'s report (slightly abridged):

http://www.patrick.af.mil/shared/media/document/AFD-070716-028.pdf

Test Operations Forecast
Vehicle:  Dragon Pad Abort
Issued:  4 May 2015 /1230 UTC (0830 EDT)
Valid:     6 May 2015 /1100-1830 UTC (0700-1430 EDT)

Synoptic Discussion:  Winds have become gusty out of the east and will remain so for the next couple of days as a low pressure area develops southeast of Central Florida.  The increase in winds also increases the threat of showers along the Space Coast.  Showers will be most prevalent in the morning hours and typically diminish after noon.  On Wednesday the low pressure area will drift north and east, relaxing the pressure gradient which will result in lower wind speeds over the Spaceport.  Maximum winds to 5,000 feet will be easterly at 20 knots and this is the primary abort weather concern. 
On Thursday, winds will continue to weaken as the area of low pressure continues to move northeast.  Maximum winds to 5,000 feet will be north easterly at 17 knots. 

Launch day probability of violating launch weather constraints:                                 30% 
Primary concern(s)
:            Winds > 25 Knots

24-hour delay probability of violating launch weather constraints:                             20%
Primary concern(s)
:            Winds > 25 Knots

Current weather conditions on the KSC Weather webcam feed showed a NO GO for scheduled time (winds exceed launch rules of 25 knots). This may change.

New images tweeted by SpaceX: https://twitter.com/SpaceX/status/595362474628526082

...which links to an article on the SpaceX site: https://www.spacex.com/news/2015/05/04/5-things-know-about-spacexs-pad-abort-test

A timeline for the test:
Quote
T-0:        The eight SuperDracos ignite simultaneously and reach maximum thrust, propelling the spacecraft off the pad.

T+.5s:    After half a second of vertical flight, Crew Dragon pitches toward the ocean and continues its controlled burn. The SuperDraco engines throttle to control the trajectory based on real-time measurements from the vehicle’s sensors.

T+5s:     The abort burn is terminated once all propellant is consumed and Dragon coasts for just over 15 seconds to its highest point about 1500 meters (.93 mi) above the launch pad.

T+21s:   The trunk is jettisoned and the spacecraft begins a slow rotation with its heat shield pointed toward the ground again.

T+25s:   Small parachutes, called drogues, are deployed first during a 4-6 second window following trunk separation.

T+35s:   Once the drogue parachutes stabilize the vehicle, three main parachutes deploy and further slow the spacecraft before splashdown.

T+107s: Dragon splashes down in the Atlantic Ocean about 2200 meters (1.4 mi) downrange of the launch pad.

Per L2 schedule notes, the window for Wednesday has been extended from 07:00 local to 16:00 local.

AE Video 2 for the Static Fire:

An eagle eyed person here is likely to be able to capture the second it happens (and it will be pretty much a second). Still working through some things per L2, so if we don't catch it, we should get confirmation and I'll post here.

And that's complete! Not sure if anyone captured it....was apparently very fast, mainly "smoke."

On the AE 2 stream, saw water jets activate around Dragon, then a cloud covered everything. Not much more to see.

Once the cloud was gone, Dragon 2 still happily on pad.

At Cape Canaveral Air Force Station, photojournalists set up cameras at Space Launch Complex 40 as a SpaceX Crew Dragon spacecraft is being prepared for a test to simulate an emergency abort from the launch pad. The ability to escape from a launch or pad emergency and safely carry the crew out of harm's way is a crucial element for NASA's next generation of crew spacecraft. SpaceX will perform the test under its Commercial Crew Integrated Capability (CCiCap) agreement with NASA, and will use the data gathered during the development flight as it continues on the path to certification.

From KSC-PAO, window now opens at 0900 local:

SpaceX Adjusts Test Window

SpaceX reported this evening that its Pad Abort Test window will open at 9 a.m., rather than 7 a.m. Media buses will depart the press site promptly at 7:30 for the ITL Causeway.

NASA will provide updates about the test on the Commercial Crew Blog and air the test live on NASA Television 25 minutes prior to T-0.

Good morning boys and girls. So we're keeping an eye on the T-0. NASA TV will go live 25 minutes before the T-0 (about 90 mins from now if they look good for the opening of the new window).

Live update thread, so updates only, but this is a two minute event by nature of the flight, so we're going to be going screenshot crazy. Screenshots are updates, so we'll take those!
