<p>Last week, several rounds of storms moved through areas of the Midwest, producing significant wind gusts and flash flooding. Another cold front will arrive shortly after the previous front leaves, sparking a new wave of severe storms, including potential for flash flooding.</p><h1>Forecast</h1><p>Wind shear will increase across the Plains and Midwest as a strong trough moves across Canada, while a cold front will cut into the United States. Along the front on Monday and Tuesday, isolated to scattered severe storms are possible. Instability will be somewhat limited, so severe storms are more likely in the afternoons when daytime heating can add energy to the atmosphere.</p><video src="https://media.weathernationtv.com/app/uploads/2026/08/08-16 rnc overnight-1786930238582.mp4" controls="true" width="100%"></video><h1>Outlooks</h1><p>As the front dips into the Upper-Midwest on Monday, scattered severe storms will be possible from Sioux Falls down to central Nebraska, with isolated severe storms possible from NW Oklahoma though Minnesota.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 055647-1786967815593.jpg"></p><p>Wind and hail damage are the primary hazards with these storms, but a few tornadoes are possible as well (below).</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 055707-1786967835695.jpg"></p><p>As the front swings farther south and east on Tuesday, another round of scattered severe storms is anticipated from Nebraska though western Illinois.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 055735-1786967861681.jpg"></p><p>By Tuesday, heavy rain will become a bigger hazard, with scattered flash flooding possible for areas in dark green (below).

Cold Front Brings Severe Storms Back to the Midwest

<p>A ridge of high pressure continues to dominate the southern tier of the US, sending storms riding around the ridge through the Midwest and Northeast. Under the high-pressure block, extreme heat and humidity will persist, lasting into this week for some many. The long-lasting heat dome has triggered heat alerts from Missouri through Florida, with extreme heat warnings in effect (pink boxes, below) along with many heat advisories. Highs will soar into the triple digits, feeling 5-15 degrees hotter with the humidity. Make sure to find adequate ways to stay cool!<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 054833-1786967322078.jpg">Feels-like temperatures remain dangerously hot across the central and southern United States. Many areas will feel like 110-115 in the afternoon.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 054929-1786967376957.jpg">Some places could be so hot that we're threating records around the south as well. Especially in the Sunshine State</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 055433-1786967708716.jpg"></p>

<p>The last few days Mother Nature has turned down the heat somewhat for the Southwest, with the extra clouds and monsoon storms back in the picture. As we get through the work week, high pressure returns westward to the Desert Southwest. <strong>Extreme heat alerts</strong> has been issued for cities including Phoenix, Vegas, Tucson, and Yuma.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 041704-1786875443493.png"></p><p>Monday high temperatures will return to the upper 100s and low 110s for the Southwest. So, make sure you stay hydrated and look after the elderly with the high heat returning. </p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 101847-1786983611724.png"></p><p>If you thought the hot temperatures would be a short-term thing, you would be wrong! Hot temperatures are here to stay for end of August.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 102046-1786983656766.png"></p>

Totality will only cover a small portion of the globe, however, while many others will see a partial solar eclipse.<br><br>A solar eclipse happens when the moon moves between the sun and earth, casting a shadow on the Earth's surface. There's a small "hard shadow" where the total solar eclipse occurs, where the sun is completely obscured by the moon, leaving only the outer ring, or corona, of the sun visible. The larger "soft shadow" covers a larger portion of the globe, but only a section of the sun will be obscured. Even though both are eclipses, the experience in the path of totality is completely different than in the partial zone. Totality ushers in darkness and massive changes, including temperature drops, changes in animal behavior, and more. If you have the chance to see a total solar eclipse, it is highly recommended you take advantage of the opportunity.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-07 124538-1786128790332.png"></p><h1>Path of Totality</h1><p>People in parts of Greenland, Iceland, Spain, and an incredibly small piece of Portugal, will be able to experience totality if skies are clear enough. The eclipse will begin in the arctic circle before dropping south to cruise over the North Atlantic and eventually western Europe.<br><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-07 124037-1786128740977.png"><br>Western Iceland, including Reykjavik, will get to experience totality for a about 60 seconds in the late afternoon on Wednesday, August 12th. This will occur around 5:45 - 5:50 GMT from north to south.</p><video src="https://media.weathernationtv.com/app/uploads/2026/08/2026-08-07 13-00-09-1786129629600.mp4" controls="true" width="100%"></video><p>Some lucky folks in Spain will have nearly two minutes of totality (toward the middle of the path), while folks closer to the outside of the path will only get about 20-30 seconds of magic. The sun will be approaching the western horizon, or sunset, as totality occurs, making for a truly incredible sight. Totality begins on the northern coast around 8:26 pm local time (CEST) and will end as it moves south of Mallorca in the Mediterranean around 8:33 pm.</p><video src="https://media.weathernationtv.com/app/uploads/2026/08/2026-08-07 13-00-28-1786129642319.mp4" controls="true" width="100%"></video><h1>Partial Solar Eclipse</h1><p>In the United States, only a partial eclipse will be visible and only for a portion of the country. A partial eclipse will be visible in the early afternoon, peaking around 2:00 pm ET, from portions of Montana to eastern North Carolina. Only a small sliver of the sun will be obscured for many, with about a fifth of the sun obscured in northern New England, mostly in Maine. All of Alaska (expect the far western Aleutians) will experience a partial solar eclipse as well. Southern Alaska will see a quarter of the sun obscured, peaking around 8:15 - 8:30 am Alaskan Daylight Time, while northern Alaska will see about half of the sun covered by the moon.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-07 124624-1786128804207.png"><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-07 124629-1786131371992.png"><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-08 103029-1786206678322.png"></p><h1>Next Total Solar Eclipse in the U.S.</h1><p>A total solar eclipse will cover portions of the United States in 2044, mostly moving through Canada, but parts of western North Dakota and Montana will get a view. In 2045, a large section of the United States will be able to experience a total solar eclipse. The path of totality runs from Northern California through Salt Lake City and Denver, before moving across the South from Little Rock to Miami, FL. It's never too early to make plans...</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-07 124638-1786131683080.png"></p><h2><strong>NASA's Research:</strong></h2><p>Through this eclipse, NASA will have multiple scientific experiments on-going related to the eclipse to help us better understand these celestial events. We spoke with NASA to learn more.</p><div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/EyvkXNZBrYk" start="0"></iframe></div>
