A very cold air mass is in place today, many record lows were broken this morning and temps are struggling in the single digits and teens for the remainder of the day. However as quick as it came in it will be exiting rapidly in 18-24 hrs as a storm system developing down south tracks over and west of the area
The disturbance is slowly diving SE , it will begin to pick up moisture from the Gulf of Mexico, gradually fire up a low pressure system that will track up the Appalachians
As the arctic high moves offshore winds will turn southeast and bring up mild ocean air, rapidly scouring out the Arctic air in place.
However due to the amount of cold air in place there will still be enough left initially that the front end part of this system will start as snow and ice for most of the area, precipitation will slowly fill in with the approaching warm front by Monday mid morning to early afternoon starting as snow and some ice then changing to heavy rain pretty quickly from SE to NW by Monday night, rain heavy at times will continue through the day Tuesday , some areas could see very heavy rain and some flooding with temperatures rising into the 40s to around 50 degrees, all precipitation will move out Tuesday evening
