Lexington
Early this morning in Lexington, temperatures fell to 45 degrees, breaking the previous record low of 47 degrees set in 2017. This sudden drop is contributing to a weather phenomenon across central Kentucky often referred to as a “false fall.” Tonight, another round of chilly temperatures is anticipated, with lows expected to hover around the mid-40s under clear skies.
Residents should brace for even colder temperatures in rural areas and valleys where temperatures may dip further. Those planning evening outings are encouraged to wear extra layers for warmth. Despite the chill, the forecast for Monday afternoon looks promising with temperatures back on the rise, potentially reaching mid-70s, ideal for short-sleeve attire again.
The current weather conditions are attributed to high pressure settling over the Ohio Valley, which is keeping the atmosphere dry, clear, and cool during nighttime hours. However, patchy fog could form in some river valleys before sunrise, but Monday should mimic the beautiful weekend weather, featuring sunny skies and low humidity.
This dry weather pattern is expected to persist throughout the week, with temperatures gradually climbing as winds shift from the north to the south by midweek. Highs are projected to rise into the low to mid-80s by Thursday and Friday while overnight lows remain comfortable in the upper 40s and 50s. The forecast for Sunday night also suggests clear and cool conditions with potential record low temperatures in some areas settling around mid-40s.
A warm-up is anticipated for Monday, with more sunshine and highs in the mid-70s, transitioning to mostly clear and chilly nighttime conditions with lows in the upper 40s. A forecaster from the National Weather Service has indicated that Kentucky is currently experiencing some of the coolest temperatures in the Northern Hemisphere this week, pointing out the distinct seasonal transition.
The first official day of fall is on September 22, coinciding with the autumnal equinox, when day and night are roughly equal in length. Looking ahead, the Climate Prediction Center projects a 33-40% chance of above-normal temperatures in Kentucky for the upcoming fall season, with a 40-50% chance of exceeding normal temperatures between September and October. In terms of precipitation, the outlook indicates equal chances of above or below normal rainfall across most of the state, except for the western tip, which leans toward below average.
As Kentucky continues to navigate through these unusual temperature shifts, residents should remain adaptable to the varying climate conditions and prepared for both the chill of early autumn and the warmth likely to return shortly.
