Narrative:
Prior to takeoff I was aware of level 4 and 5 thunderstorms that were in my departure path. Upon liftoff my radar immediately picked up the activity. I discussed this with approach on my initial call and the controller did a great job of discussing my options and vectoring me around the returns. As I approached my initial assigned altitude of 5000 ft I was given a new heading, started the turn, entered the clouds, lowered my ice vanes, was asked a question from approach about my flight conditions, and entered an area of moderate turbulence. During this high workload situation I overshot my altitude my 300-400 ft, immediately returning to 5000 ft as soon as I could slow the ascent. I feel that this overshot was caused by WX distrs at a time of extremely heavy workload in the cockpit.

Title: DEPARTING INTO AN AREA OF KNOWN CONVECTIVE WX NE OF SAC A B200 PLT OVERSHOOTS HIS ASSIGNED ALT.
Narrative: PRIOR TO TKOF I WAS AWARE OF LEVEL 4 AND 5 TSTMS THAT WERE IN MY DEP PATH. UPON LIFTOFF MY RADAR IMMEDIATELY PICKED UP THE ACTIVITY. I DISCUSSED THIS WITH APCH ON MY INITIAL CALL AND THE CTLR DID A GREAT JOB OF DISCUSSING MY OPTIONS AND VECTORING ME AROUND THE RETURNS. AS I APCHED MY INITIAL ASSIGNED ALT OF 5000 FT I WAS GIVEN A NEW HDG, STARTED THE TURN, ENTERED THE CLOUDS, LOWERED MY ICE VANES, WAS ASKED A QUESTION FROM APCH ABOUT MY FLT CONDITIONS, AND ENTERED AN AREA OF MODERATE TURB. DURING THIS HIGH WORKLOAD SIT I OVERSHOT MY ALT MY 300-400 FT, IMMEDIATELY RETURNING TO 5000 FT AS SOON AS I COULD SLOW THE ASCENT. I FEEL THAT THIS OVERSHOT WAS CAUSED BY WX DISTRS AT A TIME OF EXTREMELY HVY WORKLOAD IN THE COCKPIT.
