Example of Dry Slot

Above is an example of a dry slot. This is when pure, dry air is pulled along a storm system. Every low pressure system has one.

Typically, cross-country dry slots like this one occur in big East Coast storms. We can see the dry slot across the Southeast and Texas, even back through Mexico. It is cross-oceanic as well, if you can see the dry air way back in the Pacific Ocean into the Atlantic.
