After a stifling heat wave that set records in many parts of the west, the heat will travel away from some areas while others remain in their grip.
From mid-to-late last week, the expanding heat from the central California valley across the vast majority of the west caused several major cities to set records one or two days.
Phoenix only got two shy degrees from its record of 114 degrees Fahrenheit in May.
However, Friday’s high of 112 hit a new record on that day, breaking the old record of 1910. With 111 high and 84 low on Saturday, the average day temperature in Phoenix was 98, just 1 shy of the May record. Average daily temperatures.
Boise, Idaho rose to 98 on Saturday, capping the record for the day and falling just one degree from the record 99 for the whole of May.
Thunderstorms broke out in the heat across parts of the Western Mountain, and may have caused forest fires in Utah and Arizona. According to the Arizona Forestry and Fire Department, Arizona’s forest fire, called the Ocotillo Fire, has already burned more than 1,000 acres by Sunday morning.
At the beginning of June, much will not change across the southwest.
The heart of the heat that struck the west last week will shift slightly east, but most areas of southwest, central and southern Rocky will remain very hot,” said meteorologist Brandon Buckingham.
High temperatures in Phoenix will remain in the mid-100s to around 110 until Thursday. Likewise, Las Vegas will be out of three digits until Thursday. While both places are likely to drop from any records for the first few days of June, these temperatures are still several degrees higher than usual.
After a lull in the storm system that desperately needed rain and also brought severe thunderstorms to the northwest, California’s interior will feel hot again this week.
After spending Sunday and Monday close to normal, Sacramento and Fresno will return to the century mark in the middle of the week. Much of the inner empire east of Los Angeles will return to the 1990s.
While the interior feels hot, the coast will be a much different story.
“A near static low pressure area off the coast of California during most of this week will lead to land flow and cooler conditions on the coast,” said Taylor Royce, a weather forecaster.
Besides the cooler conditions on the coast, this pattern will also help the vast low clouds and coastal areas that cause fog.
“The variation in temperature of the building internally and the cold ocean waters often lead to continued low clouds and fog along the California coast at this time of the year,” Royce said. The phenomenon that is so regular this year is so evident that it is often referred to as the “June Depression”.
Northwest will also see a relief from the heat. While a few showers and intermittent thunderstorms cannot be excluded, the storm’s path across southern Canada will maintain the bulk of the rains north of the Canadian border until midweek.
However, this will also help maintain the severe pent-up heat in the far south. “Along the coast and inside Cascades, temperatures will rise directly around the normal range this week,” Royce said. “In the interior, the weather will be a little warmer, with most regions experiencing high temperatures of around 5-10 degrees above normal.
For Portland and Seattle, temperatures generally range from the upper sixties to the lower seventies.
Most valley areas from central Washington and Oregon to southern Idaho will spend most of the week in the 1980s.
The next few days will be very favorable for hikers and any outdoor enthusiasts to enjoy the great outdoors in the northwest.
However, there is another change on the way at the end of the week to the end of next week. Low pressure off the California coast will merge with low pressure diving south along the northwest coast and then pressure across the west.
This will bring a very active period to end the week with many showers and thunderstorms going off in the mountains and the cool rainy weather that goes back to the northwest. The heat will also be reduced in the southwest.
