The NWS includes a “slight chance of showers.”
The GFS and NAM weather models think we will be dry here, but it will rain in southern Kentucky. If the models are wrong by 50-75 miles, we will get wet.
The European model says we might see a few hit or miss showers Sunday afternoon.

Mid-Week Storm Chances
Anyone who says they know what will happen is lying.
When weather models are consistent run-to-run, and are then consistent with each other, forecasters can have confidence about what kind of storms to expect, and when we can expect them. With this week’s storm system, the models aren’t consistent.

EARLIER WE UPDATED THE HAZARDOUS WEATHER OUTLOOK TO MENTION THE POTENTIAL FOR STRONG STORMS...AND THE VERY UNCERTAIN POTENTIAL FOR SEVERE WX.THE POTENTIAL STILL EXISTS...BUT THERE ARE STILL TOO MANY UNCERTAINTIES TO OFFER ANY ADDITIONAL DETAILS AT THIS TIME.
