Extreme weather will be the main story for the United States between now and the start of July. A highly-amplified weather pattern is occurring that will bring extreme weather across the country. In the western U.S., a large ridge of high pressure will develop and provide extremely hot and perhaps record breaking temperatures. In fact, there is a slim chance that we could tie or break the all-time hottest temperature ever recorded on Earth of 134 degrees Fahrenheit!
On the East Coast, a large trough will take place that will produce plenty of rain across the eastern United States. Some areas could see four to five inches of rain within the next five to seven days.
An excessive heat warning has been issued for parts of Southeast California, Southern Nevada, and Northwest Arizona for extremely hot temperatures that could warm near 130°F and morning lows could stay in the 90s. Here is a list of possible temperature ranges expected in the Southwest by the National Weather Service:
Las Vegas (McCarran International Airport)…114 TO 117
Mesquite and the Colorado River Valley…118 TO 125
Pahrump…111 TO 114
Barstow…114 TO 118
Morongo Basin…110 TO 115
Kingman…108 TO 112
Bishop…106 TO 108
Caliente…105 TO 108
Death Valley…126 TO 129
Could Death Valley tie or break their all time record high of 134°F set back on July 10, 1913? Not only was this the all time record high ever recorded in Death Valley, but it was recognized as the all time hottest temperature ever recorded on Earth since record keeping began. Although temperatures will likely flirt near 130°F, it does not appear likely. However, you never know!
Across the Eastern United States, rainfall totals could be quite impressive with many spots seeing over two to three inches. Areas likely to see decent amounts of rainfall include the Gulf coast, the entire eastern U.S. coast, and into New England and the Northeast United States. Flooding could be an issue in a few spots, especially for those who have seen so much rainfall over the past several weeks. There are a few concerns for minor flooding across the Northeast U.S. for the next couple of days.
Bottom line: While the U.S. West Coast remains hot and dry, the U.S. East Coast remains wet and unsettled. The drought continues with record-breaking heat likely across parts of the western United States. Meanwhile, unsettled weather will continue across the East coast as showers and thunderstorms continue to develop and push into areas that are already saturated. With a highly amplified weather pattern, it is not unusual to see so many extremes occur at once across the country.
