Narrative:

I was vectored to final approach by socal approach for the long beach runway 30 ILS approach; descending into a thick overcast with drizzle. When outside the becca ILS 30 approach fix; I was cleared to intercept at 1600 feet. When outside becca; I descended momentarily in turbulence while inside the clouds; and immediately started a climb. Socal approach issued an alert that I was below the glideslope. By the time the alert was issued; I was already back at 1700 feet MSL and advised ATC. No further discussion occurred and I was cleared to land without incident; breaking out of clouds at 900 feet MSL.
