No. It never really "snows" in Anaheim. We'll get what is actually a very rare and occasional light dusting of hail or maybe some sleet, but it never sticks (as in it's gone in an hour or so) and it's a real rarity (like once in a decade maybe for the sleet, and once or twice a year for hail). We'll occasionally see a dusting of actual snow at the top of the local Santa Ana mountains, but that doesn't last long either. Any snow is in the larger San Gabriel and San Bernardino Mountains, further away.
I'd expect mid to high 60's to low 70's (F) in March.
