Discussion: A shot of Arctic air will move in from the NW starting tonight and will linger until Sunday. This should keep most, if not all, of NJ below freezing during this period. NNJ elevations and maybe Pine Barrens down
Discussion: Tonight should start a prolonged colder pattern for NJ. Nothing record breaking, just colder. It should already feel colder today than the warm sector air mass we saw earlier this weekend. This week should behave like a V graph

Discussion: After today’s milder conditions, all NJ temperatures should crash overnight tonight. We’re probably looking at a range of 20s to 30s from elevations to sea come 5-6am Sunday morning. The back-side of the departing low’s northerly cyclonic flow will
