I am just now getting a chance to look over data for the storm later this week.
Models are in good agreement that we will see a storm move through the mid-section of the country Friday, but that is the extent of the agreement. One of the models, one of my favorites, is splitting the storm and taking the bulk of the system south. It would still bring snow through southeast Missouri, southern Illinois and western Kentucky Friday evening and Saturday.
Other models take the storm right over the above mentioned area. This would bring rain changing over to snow as the system exits.
At this point it is difficult to talk specifics about what we will see. The models should begin to handle this system better within the next 36-48 hours. The storm that is going to bring the "mess" is still located over the Pacific Ocean. Once it is over land the models can get real data and crunch away at the data.
