Severe thunderstorm watch possible for this afternoon

Now that the Storm Prediction Center has placed us under a slight risk again for the afternoon, it looks as though the strengthening of storms ahead of the cut-off upper-level low is likely.  Clearing, as seen in visible satellite imagery, will help destabilize the atmosphere, helping to generate CAPE values up to about 1000 J/kg. 

 

In addition to the higher CAPE values advecting into the area, steep low and mid-level lapse rates will be moving eastward as well, contributing to the severe weather threat by making hail a more likely possibility. 

We’re expecting effective shear values to help generate a line of storms across western Kentucky that will move eastward into the county by the late afternoon.  Coverage is still going to be scattered, but cells that do develop will likely be near or at severe limits.

More updates will be posted as watches and warnings are issued by the SPC and NWS.
