Update 5:25 P.M.
The line of storms did strengthen, but not much. Line should push across Jefferson County without any significant problems. East of Jefferson County, the line should be stronger, with possibly a severe storm warning or two this evening.
On the positive side, the squall line will actually decrease the strong wind fields for an hour or two
Update 4:45 P.M.
Radar IS showing a definite uptick in strength of the approaching thunderstorms. Between now and 6 P.M., expect a line of strong thunderstorms to move across the metro area. Expect brief heavy downpours, additional strong gust winds and possibly some hail.

Line of storms still crawling eastward
As of 4 P.M. the only strong-to-severe thunderstorm left is racing across northern Clark Co. IN.
Elsewhere, the remaining narrow line of storms still lies west of the Louisville area. No severe activity has been noted in the part of the line headed our way.
The items above have worked about as expected since the weakening trend noticed a couple of hours ago. However, we are not out of the woods yet. One of the two short-term models predicts the line to re-intensify as it approaches I-65 and become strong again east of I-65 for a few hours this evening. That’s the HRRR model. It’s partner, the RAP, does not.
As of this time, local radar does not show any rebuilding… yet. If that continues and the RAP is correct, we should have minimal effects from the squall line. However, we’ll have to watch out for any intensification of the line as that would increase the potential for possible severe wind gusts – especially along and east of I-65.
I just noticed that the airport reported 61 mph wind gusts earlier this afternoon. Bowman Field’s top gust reached 56 mph. Ft Knox topped out at 53 mph. Mostly likely, if we do get thunderstorms in the next hour or two, they won’t match those winds!
