We’re on the hook for some cold rain tomorrow. Some extreme NNJ locations could even start with a wintry mix. Let’s break it down…
At 500mb, a shortwave approaching the Great Lakes region is well defined with a surface low in close southern proximity. This disturbance will move eastward and should cross over the state of New York before eventually moving out to sea over New England. This should bring an area of precipitation over our region from W/NW to E/SE between late Thursday morning and the early AM hours of Friday. This should be a cold rain for most of New Jersey throughout that time period however a wintry mix is possible at the onset of preciptation for the higher elevations of NWNJ. There’s a much better chance of this for NEPA and parts of NY state. It is worth mentioning as a small possibility said areas of NWNJ though.
In English: Expect a period of cold rain between Thursday AM and Friday AM with most falling Thursday afternoon-evening. NNJ elevations could start out with a wintry mix but little-to-no accumulations are anticipated due to a warmer surface profile. Expected total precipitation ranges from .25″ in SNJ to .75 in NNJ. For CNJ…let me check my math…about a half inch lol. Again all should clear by sunrise on Friday, if not earlier and closer to midnight tomorrow night. Winds could get a little breezy behind the rain Friday morning but should subside heading into Friday night. I’ll have a special event weekend forecast posted tonight and the regular statewide weekend outlook posted tomorrow. Be safe! JC
