CBC meteorologist Johanna Wagstaffe explains connection between dry Prairies, U.S. flooding
Jet stream normally carries weather systems from west to east
Hot, dry weather across the Prairies and deadly flooding in Texas and Oklahoma are both the result of a blocked jet stream, according to CBC News meteorologist Johanna Wagstaffe.

"Since the beginning of the month, the jet stream — that fast band of moving air that normally carries our weather systems from west to east — has been locked in place. In fact, it's splitting the stream in two," she said.
That means a high-pressure system is keeping hot, dry air in the Prairies while a low-pressure system is bringing in moisture from the Gulf of Mexico, she said.
