A Flood Watch and a Winter Storm Watch are out for the entire region late Tuesday through early Thursday. Heavy rain develops Tuesday night into Wednesday morning and may put down 1”-3” in some areas. Arctic air pushes in from west to east on Wednesday with heavy sleet and snow taking over. That setup could produce several inches of accumulation. Snow will slowly end from west to east Thursday as bitterly cold air continues to push in.
A major storm system will have a prolonged impact on the weather across central and eastern Kentucky. This all gets started on Thursday and will last through early next week.
The setup will feature an arctic cold front stalling out just to our south and east by Thursday night and Friday morning. Waves of low pressure will develop along this boundary and each will throw plenty of moisture into the region.
The initial batch will be in the form of Rain into Thursday night. Cold air seeps in from the west and northwest on Friday and we see a switch over to a mix and snow in central and western areas. Heavy rain is likely in the southeast, but may change to some snow Friday night.
Arctic air moves in for Saturday as we have a lull in the precipitation. The next round arrives Saturday night in the form of snow and ice for many. That continues into early Sunday before some rain mixes in as temps try to go above freezing for a time. This is when the flood threat really increases for southeastern Kentucky.
The next wave develops and works through late Monday into Tuesday. This may turn into much more of a snow maker as bitterly cold air moves in behind it.
