The models as well as the synoptic pattern both are suggesting the possibility of snow showers for much of Kentucky Saturday night. The GFS shows a fast-moving piece of energy rotating through the longwave trough overnight Saturday which will help to reinforce the cold air for Sunday. The NAM shows a couple of pieces of energy moving through the trough as early as Saturday morning
Snow showers could develop across northern KY in the late afternoon/evening and across southern KY a few hours later. The warmth from this week’s storm will keep the snow from accumulating and it should only persist for a few hours. Temperatures this weekend will be well below normal as highs will be in the upper 30s fromLexington to Louisville and around 40 in Bowling Green. The European model (ECMWF) has joined the GFS is suggesting a warmup by the middle of next week . The cold, arctic air will remain just north of the Canadian border through the middle of the month and the models are flip-flopping on whether or not there will be any further cold-air intrusions into the Eastern U.S. The fact that the teleconnections (EPO, NAO, PNA) are not forecast to be at any extremes suggests a very changeable weather pattern with no extremes of warm or cold.
