Coldest November since 1976
A historic early taste of winter in mid-month helped to make November 2014 a top five coldest November for much of Kentucky. The month started cold and after ten days many locations were already between four and five degrees below normal. The coldest days in that period were the first two days of the month, when a trace of snow fell across northern Kentucky and several inches fell in the higher elevations along the Virginia border. Record lows were set on the morning of the 2nd in Jackson and Frankfort while a record low maximum was set in London. The first of two arctic cold fronts moved across Kentucky on the 12th, beginning a stretch of seven days when high temperatures stayed below even mid-January normal high temperatures and low temperatures dropped into the teens. A stronger second blast of arctic air moved across the state on 17th, ushered in the first significant snowfall for many areas. Snowfall ranged from a few tenths of an inch across southern Kentucky to as much as five inches along the Ohio River. For Bowling Green, it was the earliest measurable snowfall in November since 1968. Numerous record low maximum temperatures were set on the afternoon of the 18th as high temperatures stayed in the 20s. Louisville tied a record low maximum that was set in 1880. Record low temperatures were set in several locations on the mornings of the 19th, 20th, and 21st. The coldest spot was Henderson County, where the Kentucky Mesonet weather station recorded a low of 2.1 degrees on the morning of the 18th. The week-long stretch of well-below temperatures was only the second such mid-November stretch and the first since 1937. Temperatures warmed into the 60s from the 22nd to the 24th but cold air returned from the 25th to the 28th. A surge of warm air pushed temperatures back into the 60s on the final day of the month. Overall, temperatures across the state were between six and seven degrees below normal for the month with many locations experiencing their coldest November since 1976. Precipitation for the month was below average, with most locations receiving around 60-70% of normal.
