Narrative:

We were taxiing out to runway 35L in aus when ATC reported a windshear reports on the departure end of the runway. The captain then said we should plan for a possible wind shear encounter so I changed the data per the procedure and it changed the departure flap setting from one to five. I then changed all the information in the FMC and told the captain that the flap setting changed.we were just pulling up to the runway and had been cleared for takeoff. We were talking about the profile; but forgot to reset the flaps to five. We took off and used the higher rotate speed and lifted the flaps via the profile. The flight proceeded and we landed without incident.

Title: When alerted to reports of windshear on initial climb the flight crew of a B737-700 recalculated their takeoff data appropriately but failed to reset the flaps to the required setting prior to takeoff. No adverse effects resulted and the flight proceeded uneventfully.
