I've never seen the entire CONUS covered by above average chances.

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. A trough of low pressure over western Kentucky, Tennessee and
northern Mississippi is forecast to move southward toward the
northeastern Gulf of Mexico where a low pressure area could form in
a few days. Some gradual development of this system is then possible
while it meanders near the northern Gulf Coast through the middle
of next week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

I don't remember ever seeing a storm being born on land and then taking a cruise down to the gulf
to wander around.

But I am not used to boiling temperatures over half the country now, either.
