A Prolonged And Record Heat Wave Is Building Over The West This Week

“Temperatures could exceed 110 degrees Celsius in parts of the South West, where an extreme heat warning is in place,” the Weather Prediction Center wrote. The most difficult areas will be in the south-west, where the heat will be the most intense. “A few records may be broken, but record high temperatures are very high for this time of year,” the NWS office in Los Angeles said. “Record-breaking or not, this prolonged heat wave will be very dangerous.” Over 100 discs could fall in the West.

Prolonged heatwave in the southwest

The kind of heat that will be felt from San Diego to Los Angeles to Phoenix will be hard to handle even for the locals. “This heat may be record high and will cause a very high risk of heat illness,” the NWS office in Los Angeles said. “Triple-digit heat is expected for many valley and mountain locations. Even hotter conditions are expected through Labor Day weekend into early next week.” The heat will begin on Tuesday, with a gradual warm-up each day through the week and will peak by the end of the week. The reason for the extreme conditions is a persistent area of ​​high pressure that sits over the region, creating what meteorologists call a “heat dome.” This intensely heated dome causes the high pressure to act as a lid on the atmosphere. As the hot air tries to escape, the cap forces it to retreat, heating up even more as it sinks. The result will be intense summer heat, running 10-15 degrees above normal. “Extreme heat warnings are in effect for nearly the entire forecast area beginning Wednesday and will continue through next Monday,” the NWS office in Los Angeles noted. The forecast calls for temperatures of 110-115 degrees in the deserts and San Fernando Valley, with temperatures of 90-100 along the coast. It’s hot enough to potentially break records there too. Watch: 5 things to do to stay cool in a heat wave In Phoenix, the “dry heat” will give way to wetter conditions through Thursday and Friday. That will cause the actual temperature to drop slightly, but the NWS in Phoenix warns that the humidity could actually make it feel warmer. In Southern California, a few morning clouds Friday morning could break through, providing a brief reprieve from the heat — but it will be short-lived. “There will be new warming leading to an oven-like day on Sunday,” the NWS office in Los Angeles said. Even downtown Los Angeles could reach 100 degrees Sunday with Death Valley potentially hitting 125. That heat extends into the San Joaquin Valley, where record temperatures are possible. “Confidence is rising as these are the hottest temperatures so far this year,” said the NWS office in Hanford, California. “Record high temperatures are possible from Thursday with the best chance for record highs on Sunday and Monday when the heat is expected to peak.” The Labor Day holiday will be one of the hottest days of the event, with the heat potentially lasting most of next week – making heat-related illnesses a huge concern amid the oppressive heat.

Record heat for the Pacific Northwest

Maximum heat for the interior Pacific Northwest will be felt for most of this week as high temperatures soar in Seattle, Portland and Boise, among others. “Daytime highs between 10-20 F above normal and overnight lows between 15-20 F above normal are possible,” the Weather Prediction Center said.
The heat is expected to peak Wednesday with highs in the 90s and possibly triple digits for parts of the West Basin near Spokane, Washington — even breaking records. “Highs are expected to be 10-15 degrees above average as many locations could test daily records for maximum temperatures,” the National Weather Service in Seattle said. Near Boise, Idaho, temperatures could reach 20 degrees above normal, with record heat expected by Tuesday. And in Seattle, high temperatures are expected to peak in the 80s to low 90s. The extreme heat should break by the end of the week, bringing temperatures back into the 70s for Labor Day weekend.

A Labor Day tropical system could be on the horizon

The tropics are also heating up ahead of the holiday weekend. The National Hurricane Center is actively monitoring two areas in the Atlantic for tropical development as we will likely have our next named tropical system before Labor Day. An area of ​​low pressure several hundred miles east of the Lesser Antilles has the greatest potential to become “Danielle.” “Although environmental conditions are less than favorable, some gradual development of this system is expected over the next few days and a tropical depression is likely to form later this week,” the NHC said. There is an 80% chance this area will become a tropical system within the next five days, according to the NHC. Forecast models have this system heading west, staying north of the Caribbean islands and curving north, avoiding the Bahamas. The storm should remain offshore as of now, but things could change between now and next week. Although the storm should remain offshore, there will still be impacts on the East Coast through the Labor Day weekend. The storm could produce windy conditions and even strong rip currents for the East Coast. How close the storm gets to the US will determine how strong the winds and currents will be. Closer to shore they will be stronger, farther from shore they will be weaker. The NHC is no longer monitoring the region in the western Caribbean for development. However, this area is still producing clouds and rain that will pump tropical moisture to the Texas coast. This will increase the chance of rain in South Texas over the Labor Day weekend. How to prepare for hurricane season Another area to watch is a tropical wave just off the coast of Africa. This area could also become a tropical depression over the next few days, although its lifespan could be short-lived. “By the end of this week, the disturbance is forecast to move into cooler waters and no further development is expected,” the NHC said.
