As the golfing world converges on Louisville, Kentucky, this week, rain is also taking aim on the region.
According to AccuWeather Senior Meteorologist John Gresiak, "Episodes of rain and thunderstorms are likely through Saturday."
While it will not rain the entire time during these days, there is the potential for drenching downpours and a couple of rather robust thunderstorms. Highs most days will be in the 80s.
A series of disturbances will roll southeastward along a stalled frontal zone from the central Plains to the Ohio Valley during the latter part of this week.
"Friday looks to be the worst day in terms of disruptions from rainfall and thunderstorms," Gresiak said.
Due to the frequency of showers and storms on Friday, temperatures much of the time will be in the 70s.
A shift in the frontal zone is forecast this weekend. A shift in the front by as little as 50 to 100 miles will make the difference between clouds and rain and some sunshine and dry weather.
"The weather on Sunday is likely to be the best for golf and the final round of the PGA Championship," Gresiak said.
The caboose in the train of disturbances is forecast to have moved by on Sunday, causing the rain to shift to the south and east.
Low clouds and fog could linger for a time in the morning on Sunday, before some sunshine breaks through later on for the final round.
The tropics may become active this weekend and into early next week.
The risk of drenching and locally gusty thunderstorms has expanded to parts of Southern California, Arizona and Nevada.
The Northwest is dealing with yet another record-challenging heat wave to close out July. While relief will come next week, this heat wave will not be the last of the summer.
Flooding monsoon rain will continue this week in India and southeast Pakistan, but a drier pattern is expected to set in during August.
Volcanic ash was sent 19,812 meters (65,000 feet) into the air as a result of the eruption, the Australian Bureau of Meteorology reported in an volcanic ash advisory.
A cold front will press southward bringing relief from the heat to Spain, Italy and southeast Europe late this week.
