Narrative:

Climbing out from iad with light rain, tat +15 degrees C. Upon reaching FL250, encountered heavier rain, tat +2 or 3 degrees C. Heard a compressor stall, called first officer engine anti-ice. Looked at wiper bolt and windshield. They had significant ice, I called for wing anti-ice. FL265, the precipitation stopped and could see stars. We left the engine anti-ice and wing anti-ice on until all ice was gone from the wiper bolt and windshield. Leveled off at FL270, continued flight to cvg, was normal. Follow up inspection revealed foreign object damage to all 3 engines. The tat never went below +2 degrees C. The conditions were a fast moving cold front and super-cooled water droplets.
