Lots of Interesting Weather Possibilites - Even a Chance of Some Wet Snow?

There was very heavy rain early this morning in Northwest New Jersey producing some localized flooding and many car accidents. There will be another chance of some heavier showers and thunderstorms later today. Tomorrow morning there will likely be some very heavy showers and thunderstorms, which could lead to some small stream flooding. Friday it will clear out as the cold front finally comes through and brings much cooler air with it. This is when things could get a little interesting as an upper level low pressure area will drop down from Canada with some unseasonably cold air. This unseasonably cold air will produce instability in the atmosphere, which will cause showers and thunderstorms to develop, which could produce some wet snow underneath the exact path of the upper level low, which right now would be through Western and Central Pennsylvania. It is remotely possible that some wet snowflakes could mix in with any showers that linger into Sunday night over the upper elevations of Northwest New Jersey, depending on the exact path that the upper level low takes. If this were to occur there would certainly not be any chance of accumulation as the air temperatures will be well above freezing. This would be possible because the upper level low will have very cold air with it in the upper layers of the atmosphere, even though temperatures will be well above freezing at the surface. It is an interesting possibility but it would not be a problem in any way.
