We’ve been seeing early-June weather lately. Sunshine daily, with temps. in the lower to middle 80s is very reminiscent of early Summer rather than the very beginning of Spring. But that’s all about to change.
A cut-off area of low pressure is drifting slowly through the nation’s mid section. As the system is drawing closer to Kentucky now, clouds are already beginning to increase this afternoon. Tonight, rain will overspread the entire area as the moisture finally catches up.
Tomorrow, after the first batch of rain has pushed through, it’s possible that we could go into a “dry slot” for a while during the afternoon. This is an area that you see lots of times with areas of low pressure that are really wrapped up tight. As this dry slot works through, sunshine may be common for a brief time which will allow for the surface airmass to destabilize. At the same time, the cold air aloft generated by the cut-off low pressure will drift overhead. This will possibly create a situation where you have very warm surface temps and very cold upper air temps...which means that the air will want to rise violently and create thunderstorms.
The Storm Prediction Center has all of central Kentucky in the Slight Risk zone for severe weather tomorrow. Hail will be the main threat. Isolated damaging wind and a few weak tornadoes are possible too. Keep an eye on weather conditions tomorrow, especially during the afternoon.
