Narrative:
While attempting to deviate for significant WX, with a block iv autoplt in use, an approximately 350 ft deviation occurred, exceeding the assigned altitude. No comment was made by ATC and altitude deviation was corrected within 2-3 seconds. At the time of the incident, both the pilot and first officer were attempting to circumnav the WX and trying to handle multiple ATC calls.
