Most, if not all, of NJ should see a mild and breezy (out of the SW) start to the night. Some might experience a few early-AM boomers embedded within the short-duration period of heavy rainfall.
By the time the sun rises tomorrow (let’s give it until 8AM at the latest), most precipitation should be through NJ into the ocean and the cold front should be passing through. You’ll know when the cold front is through because winds will switch from breezy-to-gusty out of the SW to gusty-to-hey now out of the NW.
This low pressure system has strong support to remain under 985mb as it tracks through just to our N. Isobars should be tightly aligned out of the NW once the cold front drags through NJ on Sunday morning. Therefore the winds are probably going to be the headline for Sunday with gusts to 40mph likely and possibly even to 50mph in localized instances.
This is the kind of setup where most of NJ sees their high temperature in the morning before temperatures gradually fall through afternoon and especially evening hours. Temperatures should then drop into the 20s and 30s by early Monday morning with gusty NW winds persisting overnight.
In English: It will feel mild and breezy/gusty heading into tonight. A 1-2 hour period of rainfall is likely before/during sunrise tomorrow. Boomers are possible within this period of moderate-to-heavy rainfall but not guaranteed. From Sunrise-forward tomorrow, gusty NW winds are expected with dropping temperatures. Sunday night into Monday morning looks cold with temperatures bottoming out below freezing for many. Areas closer to the ocean could hang just above freezing in the 30s. Be safe! JC
