Just days after temperatures soared into the mid 70s, New Jerseyans are now bracing for some much colder weather. The National Weather Service says a cold front that was moving through the area on Sunday will be followed by a large chilly air mass. That will drop overnight lows into the high 20s and low 30s in most areas. That’s spurred forecasters to issue a freeze warning for most northern Jersey counties, which will be in effect from midnight Sunday to 10 a.m. Monday.

Meanwhile, many southern areas will be under a frost advisory that will be in effect Monday from 2 a.m. to 8 a.m. Full Story in North Jersey.
