Isaac Slowly Works Towards KY

Not only is Isaac working towards KY... it's going to dump a lot of rain as it makes it run towards the Commonwealth!

Since last night the model data has been trying to get slightly more aggressive with rainfall in other parts of KY. That could also include parts of southeastern KY too!

Timing Isaac:

  • Friday - Some of the outerbands could creep into KY. Most stay dry... but those bands could invade!
  • Saturday - Morning hours look dry for us. Afternoon-evening Isaac arrives.
  • Sunday - The steady and heaviest rounds of rain begin for us.
  • Monday - The back edge begins to clear KY.


HPC's latest projection from 7am Thursday.

Now this is suggesting upwards of 7" of rainfall around Louisville and back towards Indy. That's a lot of rain no matter how stretched out the forecast appears. Around here we are pushing more towards 3" in some cases.

GFS Rainfall

Not quite as heavy with the GFS. As a matter of fact this model run is taking the heavier rounds more towards the north. It's similar to what I have been thinking which is around 1"-2.5" for the folks around here. That's something we can handle without major issue.

The latest full run of the NAM cuts off on Sunday afternoon... but again favors the GFS an awful lot!

Similar... but not as intense with the heavy rainfall!

 I'll have another update later today!
