Wednesday started out as a breezy but cool day across the area. Plenty of sunshine with southwesterly winds around 5-10 mph gave a brisk chill to the air, but quickly warmed up into the low 50’s across south-central Kentucky. Through much of the morning and early afternoon hours, sunshine filtered in over the region, but increasing clouds from the southwest has since moved in as overcast conditions have began to take over. High pressure is currently situated over the Great Lakes region and will continue its progression towards the east. Tightening pressure gradients between the stout high to the north and deepening low pressure system to the south has been increasing easterly winds across southern Kentucky. Into the evening hours, winds are expected to settle down a bit as relative humidity values will rise. Clouds will continue to thicken and lower, especially over central and south-central Kentucky. Overnight lows are expected to be cold with temperatures dropping into the low 30’s. Areas to our north could see slightly colder overnight lows as clouds will be slower to move in, allowing temperatures to drop a few degrees below the freezing mark.
Looking ahead for tomorrow, temperatures will once again start off very cool, but should quickly warm up into the low 50’s for southern Kentucky where cloud cover and approaching showers will keep temperatures slightly cooler than areas to our north. Both the GFS and NAM models continue to trend the system tracking to our south as the Tennessee Valley Region and points southward will see the best chance for precipitation. Areas along southern Kentucky should see rain showers filter into the area, but should remain light at best. The HPC suggest that the broad area for heavier rain will occur to our south and eventually to the southeast and along the eastern coast. Counties along the KY/TN border will see the best chance for showers.
The aforementioned high pressure will continue to move off towards the east coast as any showers along the southern and eastern parts of the state should come to an end as winds begin to back towards the north by Thursday evening. Thursday night should feature a rather calm, clearing night with a low around 40 degrees. Skies should begin to clear throughout the overnight hours and into Friday morning, as the long awaited arrival of spring will finally impact the region. Highs for your Friday are expected to reach the low to mid 60’s under mostly sunny skies! Winds should remain light and from the north around 5-10 mph!
