June 18- Tropical Cyclone Discussion- East Pacific Ocean

There is a 60% chance for tropical cyclone formation for a system to the west of extreme south Mexico. The system in mention has not become better organized over last night. However, there remains a window of opportunity in which this system can become a tropical cyclone (depression, storm, etc.)
Infrared satellite imagery is messy right now. There is a cluster of strong storms to the west of the low pressure system. This may be interfering with development of this system. There is currently no defined center of this system, with no circulation evident.
This system may actually be overhyped, as I am not seeing this system developing with how horribly disorganized this system is right now, as well as the cluster of storms to the west of the low pressure system.
Current surface analysis by the OPC doesn't help this system's case, but it does infer that potentially the cluster of storms could be actually related to the low pressure system. However, it's really hard to see right now because of how messy the system is.
There's a tropical wave moving onshore to Central America. Showers and storms are associated with this wave, and I will check up on this wave once and a while in case it becomes eligible for development when it crosses into the East Pacific Ocean.
Models have dropped off this solution of even making this system into a tropical cyclone. Either way, the models that do participate in this run keep it very close to land, with a couple models even making a landfall. I'm not going to rely on these models closely, because the models are sending mixed messages.
Even more models dropped off the intensity forecasts than the tracks of this storm. Maximum strength reaches tropical storm status, however even that may not happen.

I will watch this situation closely and issue more forecasts as necessary.

June 18- Severe Weather Discussion

There is a slight risk of severe weather for portions of the: Central Plains, Midwest, Southeast. Mainly affected is: The Nation's Midsection.

There is currently a sector of moist and unstable atmospheric conditions in central KY east into KY/TN. However, there are several clusters of showers and storms ongoing in the areas. That will affect the atmospheric conditions into today. Those are specific details that will have to be worked out and will likely become a nowcasting event. (Nowcasting= forecasting as the event is happening)

It looks like moderate to stronger showers and storms will progress from Central Illinois into Central Indiana moving WSW.

The areas to watch for today's severe weather are:
-Central/South IL
-Central/South IN
-East half of Kentucky

This comes as a short range model projects a strong cluster of thunderstorms to come down into Kentucky after battering the first two areas mentioned.
