An area of light snow is currently occurring to the south of Philly from the DC metro region to central Delaware and it looks like this trend will hold through this evening hours sparing us from any problems. This area of precipitation appears to be headed east towards the South Jersey coast where an inch or two of wet snow could accumulate during the next several hours. Looking ahead, significant rain is likely here Wednesday night into Thursday and then the overall temperature pattern will change beginning on Friday. An Arctic front will move through the region on Friday accompanied by strong wind gusts and perhaps some snow shower activity. Cold air outbreaks will occur more frequently from mid-month on through the second half of January, and the cold air will last longer compared to recent weeks.
