Each round was associated with a cold front moving through the area. Ahead of the first boundary on Thursday, we saw mild temperatures in place across the region. In fact, highs peaked on Wednesday with breezy southwesterly flow pushing highs to around 70. Behind the front, we took a major step back. Lows on Friday morning were in the low to middle 20s for much of Kentucky, only rising that day into the 40s and some even staying in the upper 30s. More significant cold air followed the secondary cold front on Sunday. Below is a look at lows this morning across the state from the Kentucky Mesonet. Clear skies and calm winds created the perfect recipe for what is now the coldest morning of the fall season so far. Many areas dipped into the upper teens to low 20s, and some even dropped into the middle teens. The coldest location was Harlan, which plummeted to 13! For perspective, normal lows for this time of year run in the middle 30s.
