Potential for scattered severe storms Monday between 5-10pm. Best chance for Southern and Western sections of NJ. A deep Southerly flow will develop Monday ahead of a cold front. This will cause temperatures to pop into the 60s (cooler at the coast). Showers are possible just about anytime. Some of the rainfall will be heavy. An inch of rain will be common. It’ll be windy. Thunderstorms most likely will accompany the front by evening. Some of the storms may turn severe, especially over Southern and Western sections (map displayed).
