Discussion
After yesterday’s mix of cold rain and wet snow in the Philly metro region, today and tomorrow will be relatively tranquil as high pressure builds across the Mid-Atlantic region. It will, however, turn quite active again as we begin the upcoming weekend with an Arctic cold front advancing into the eastern US. This cold frontal system will have a lots of support in the upper atmosphere which will help to contribute to the formation of surface low pressure along the frontal boundary zone and this system will intensify rapidly as it pushes northeastward. Rain is likely here ahead of the Arctic front from Friday night into early Saturday and some of it can be heavy at times and a strong thunderstorm is also possible. On the back side of the front later Saturday, temperatures will drop sharply, the rain will change over to accumulating snow across interior sections of the Mid-Atlantic and perhaps all the way into the N/W suburbs along the I-95 corridor. The biggest story with this early weekend weather event will be the winds which can gust into the 50-60 mph range later Saturday into Saturday night. A very tight pressure gradient will form between the departing strong storm system and a high pressure in the southern states. High winds of this nature raises the possibility of downed tree limbs and power outages in the Mid-Atlantic/NE US from later Saturday into Saturday night.
