Memorial Day is commonly referred to as the unofficial start of summer, and for those in the Southwest, it will bring temperatures that rival those of July.
Sunday set the stage for several sunny and sizzling hot days over portions of California, Nevada and Arizona through the first half of this week as the mercury rose well into the 90s across the region's interior.
Those planning on spending time in the outdoors for Memorial Day should take the proper steps to stay protected from the harmful rays of the sun.
Applying sun block and wearing lighter colored clothing are just two easy ways that you can stay protected when in the sun.
Drinking plenty of water is also important to ensure that you stay hydrated, especially if you are partaking in strenuous activities.
Unlike the heat wave that occurred over the region in the middle of May, areas closer to the coast are not expected to get quite as hot as those farther inland due to the influence from the Pacific Ocean.
However, cities such as Los Angeles, San Diego, San Jose and San Francisco are still expected to have temperatures 5 to 10 degrees above normal through at least Tuesday.
Each morning through the middle of the week is also expected to start off with areas of low clouds along the coast of California before giving way to sunshine.
Meanwhile, many areas across the region's interior could climb above the 100-degree mark on Monday, Tuesday and Wednesday.
This includes cities such as Phoenix; Las Vegas; and Fresno and Palm Springs, California.
Death Valley may even touch 115 degrees which would make it the highest temperature recorded there since mid-September.
Looking ahead towards the latter part of the week, the heat is expected to ease, but still remain a few degrees above normal.
Dry weather will also persist through much of week with the only chance of precipitation coming on Friday over the mountains of Arizona.
Cool and unsettled weather will continue across the Northeast through late week.
Relief is on the way for portions of the Plains that are in the grips of the ongoing drought.
A tropical wave west of the Cape Verde Islands looks like it could be the next named tropical storm in the Atlantic Basin.
It was a rather active past few days with tornadoes, flash flooding, and damaging winds targeting many communities from Tennessee to Massachusetts and in Colorado.
A pair of tropical threats will target areas from China and Taiwan to Guam this week.
Following the thunderstorms of early in the week, the Nation's Capital will see cooler and less humid air midweek.
