More Severe Weather Expected

The most recent SPC outlook still has Louisville and most of our central and northern region in a slight risk category for severe thunderstorms.

Wind damage is the most likely result according to the SPC. Yet, the NWS office here in Louisville continues to advertise more of a large hail bias.

At this very moment (1:25pm), clouds have rapidly increased with some scattered downpours developing. However, instability will wane some if the clouds continue to hang around. We need more heating if a Watch is going to be posted anytime soon.

Therefore, while SPC feels a Watch is likely, I think we need to look at the current picture and assign a 'probable' variable based on whether or not peak instability will occur during peak heating time. And that is contingent on the amount of cloud cover available.

I assign a 50 percent chance for a Watch to be issued. This would possibly include the Louisville area. I do think hail and high winds are equal threats this time around.
