After a major winter storm came through the area dumping a widespread 10-25 inches of snow over the area, ice is becoming a growing threat for tomorrow
We have a strong storm system tracking towards the Great Lakes today , initially this storm will brig in warmer air and a warmer pattern over the next 5 days, but with a warm front coming, cold air damming and a new heavy snow pack over the area, cold air will be stubborn to leave at the surface , warm air aloft will take over aloft starting tonight but will not take over at the surface until tomorrow afternoon and thus we have a widespread freezing rain and sleet event tomorrow morning through early afternoon as temperatures will be stuck at or below freezing before rising into te upper 30s to mod 40s area wide by late afternoon as the warm front comes through. The ice threat though will be more widespread, al the way to the coast because of the snow pack in place.
Ice storm Map
Here is my ice event map , initially areas in the dark purple and red color will start off as dominantly sleet and snow mixed then quickly change over to a prolonged period of freezing rain/drizzle then eventually all rain , the light purple area will likely start off as freezing rain/drizzle perhaps a little sleet mixed in before changing to a moderate to heavy rain fall
For many areas flooding may become an issue, because eventually all areas will change to a moderate to heavy rain as warm air takes over, and amounts of 1/2-1 inch can be expected , that on top of 10-20+ inches of snow and storm drains covered by huge piles of snow will likely lead to ponding and minor flooding issues
Tuesday Thursday slightly colder air will come in with the passage of a cold front , with seasonal temperatures and highs in the low 30s interior to low 40s along the coast and lows in the low 20s interior to low 30s along the coast, another storm system has to be watched for Thursday for potential snowfall , especially for the Mid Atlantic area to the Philadelphia metropolitan area.
Another shot of Arctic air can be expected behind that potential storm system for next weekend as arctic air makes another appearance starting in the upper Midwest then dropping south and east into our area with temperatures below to well below normal along with continued chances for snowfall.
