i was wondering this too but after looking into it further, that event was just synoptically different as a whole. we had a GL low that brought a cold front down here followed by some gusty flurries. I think that event was farfetched to begin with and we were j desperate because there was no trailing low or trough digging in the south.
this event, meanwhile, is caused by a trough digging in the south and turning negative rapidly bringing cold for the last few hours of precipitation. definitely a more promising event where we see a coastal low spawn and bring back moisture into our area for a few hours of flakes or even accumulating snow. def a more promising setup compared to most anafrontals.
