KEY MESSAGE 1...Another round of frost and freeze impacts are expected tonight where the growing season continues.

In New Jersey...Atlantic, Burlington, Mercer, Middlesex, Monmouth, and Ocean counties.

No additional frost/freeze headlines will be issued for these counties until Spring 2027.

Little change in the overall synoptic pattern is expected today and tonight with strong surface high pressure essentially overhead. The high will weaken Monday and drift to the south. Slow moderation of temperatures begin today and continue Monday.

Temperatures today will be a few degrees milder than on Saturday under sunny skies. With skies remaining clear tonight, another round of frost is possible tonight into Monday morning. Lows around the region will mainly be in the mid 30s to low 40s. Additional frost advisories may be warranted for the upcoming night...more details to come in in this afternoon's update.
