Gerst: if Dragon doesn't launch on Friday, go with Cygnus launch on May 6.

Ultimatum?

I think that Gerst said this weekend (not this Friday).

Ok I just got this sorted out...
From the AP
"If SpaceX isn't flying by Saturday, then Orbital Sciences will move to the front of the launch line, with a shipment in early May, officials said. That would push SpaceX into June."

So do I have this right......If no launch by Sat. then Dragon gets unloaded and some stuff moved to Orbital?  Parts like the stuff for the EVA?

Yes, there are the launch opportunities noted on Friday and Saturday; it does sound now like there's only room for one of them to fly a full mission before the high Beta angle cutout (30 May - 9 June) and the other will fly on the other side of that.  (Perhaps complicated by the EXT MDM failure.)

SpaceX Launch of NASA Cargo to Space Station Set for Friday, Spacewalk Wednesday

NASA and SpaceX are targeting a 3:25 p.m. EDT launch on Friday, April 18, of SpaceX's third cargo resupply mission to the International Space Station from Cape Canaveral Air Force Station in Florida. NASA Television coverage will begin at 2:15 p.m.
 The company's April 14 launch to the orbiting laboratory was scrubbed due to a helium leak in the Falcon 9 rocket that will launch the Dragon spacecraft to the space station.

Dragon is carrying to the space station almost 5,000 pounds of science and research, crew supplies, vehicle hardware and spacewalk tools -- all to support the crew and more than 150 scientific investigations planned for Expeditions 39 and 40. If needed, another launch attempt will take place at 3:02 p.m. Saturday, April 19.

NASA Television coverage of Dragon’s arrival at the space station will begin at 5:45 a.m. Sunday, April 20. Expedition 39 Commander Koichi Wakata of the Japan Aerospace Exploration Agency will use the space station's robotic arm to capture the spacecraft at approximately 7 a.m. NASA's Rick Mastracchio will support Wakata during the rendezvous. NASA Television coverage will resume at 9:30 a.m., as the Dragon is attached to the Earth-facing port of the space station’s Harmony module.

An April 18 launch will allow the space station program to plan for a spacewalk on Wednesday, April 23, to replace a failed multiplexer-demultiplexer (MDM) relay system. The prime MDM, which is operating normally, and the failed backup computer provide commands to some space station systems, including the external cooling system, Solar Alpha Rotary joints and Mobile Transporter rail car.

A separate media advisory providing NASA TV coverage times for the April 23 spacewalk will be issued at a later date.

I don't see the full forecast posted online yet, but NASA has Tweeted an update to the Saturday forecast (no change the % for Friday):
https://twitter.com/NASA/status/456795164841746432

Weather for tmw's @SpaceX launch to #ISS is 40% "go." The forecast improves for a Saturday launch attempt to 60% "go" http://www.nasa.gov/spacex

Maybe the Range was requested to support that one, doesn't mean NASA will want to go with the 22nd given the shedule juggling involved. So far only 18 and 19 dates were announced.
