Some locations in south central Kentucky remain in the lower 40s, but still have several hours in which to drop to freezing, so no changes will be made. Many locations in the Bluegrass region, especially the more sheltered valleys, will drop below freezing around midnight, and could remain there for several hours with a hard freeze possible. Highs will reach the lower/mid 60s under strong warm advection, but that will come at a price, namely south winds gusting to 30-35 mph in the afternoon and into the evening.

GKS Southerly flow will increase across the area tonight as a trof deepens over the Great Plains and high pressure moves over the Eastern Seaboard. Scattered to numerous showers will likely continue after 12Z as low level moisture continues to increase with continuing warm advection on the low level jet which really doesn't weaken much between 12Z and 18Z.
