<p>Lala continues to trace the Southern coastlines of the Hawaiian Islands. The center of circulation passed just south of the Big Island on Saturday. However, with its proximity, very heavy rain and winds gusting above 80 mph still occurred.</p><p>The Hawaii Department of Transportation reported that parts of Highway 11 on the Big Island were shut down due to flooding. More than 130,000 customers lost power Saturday as a result of the storm. As the storm moves west-northwest, expect conditions to deteriorate for each island through Sunday.</p><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2088807962383143316" src="https://x.com/WeatherNation/status/2088807962383143316"></div><p>Lala's intensity gradually increased through Saturday. Interaction with Hawaii will likely cause subtle weakening into Monday. However, once it moves into the open waters of the Pacific, expect it to return to Hurricane status.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 061614-1786882590749.png">The hurricane warning has been changed to a tropical storm warning Big Island.

The higher wind impacts will be felt on the east side of the circulation, as the front right quadrant sees the strongest winds. Tropical storm winds will start spreading west through Sunday. Flooding will likely be the biggest threat with this system, as terrain-enhanced rain could top a foot of accumulation on the Big Island. When heavy rain saturates soils, trees can be toppled more easily. Tropical storm-force winds could have bigger impacts in this scenario.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 042723-1786876055198.png"></p><p>Beach conditions are also expected to deteriorate as Lala gets closer.

Flooding Risk Lingers for Another Day

PIC2jpg-1786838081872.jpeg

<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 start a new work week, high pressure returns westward to the Desert Southwest. An Extreme Heat Warning has been issued for cities including Phoenix, 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. <img src="https://media.weathernationtv.com/app/uploads/2026/08/1-1786847315125.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.<img src="https://media.weathernationtv.com/app/uploads/2026/08/1-1786847600823.png"></p>

Heat Returning to the Desert This Week

<p>Last week several rounds of storms moved through areas of the Midwest, producing significant wind gusts and flash flooding. notably for portions of Iowa and Illinois, while Nebraska and Kansas saw their share of impacts as well. 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/2026/08/2026-08-16 04-37-08-1786876876753.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 2026-08-16 042432-1786876706940.png"></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 2026-08-16 042437-1786876722138.png"></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 2026-08-16 042442-1786876722138.png"></p><p>By Tuesday, heavy rain will become a bigger hazard, with scattered flash flooding possible for areas in dark green (below).

<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 next week for some locations.</p><h2>Central U.S.</h2><p>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 2026-08-16 063502-1786883712879.png">Feels-like temperatures remain dangerously hot across the central United States.

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.

Alana Cameron was born and raised in Canada in the city of Mississauga, just outside of Toronto. Alana is the oldest of 4 siblings, all close in age, and grew up playing outside with them in all types of weather. After graduating high school, Alana moved to study at the University of British Columbia in Kelowna for a year before transferring to Dalhousie University in Halifax, Nova Scotia where she completed a Bachelor of Science in Physics and Atmospheric Science. Upon completion, Alana moved back to Toronto where she completed a post-grad degree in Meteorology at York University. After her post-grad, she went on to complete another post-grad in Broadcast Journalism - TV News at Fanshawe College in London, Ontario. During her final year of studies she had the privilege of interning with the best in the business in Canada at The Weather Network. Once she finished her internship, she got the call from small-town Denison, Texas where she accepted a job as an on-air meteorologist at KTEN-TV, right in tornado alley, covering severe weather from Sherman/Denison (North Texas) to Ada (Southern Oklahoma). After the most active tornado season Oklahoma had seen in May 2019 (105 tornadoes!) Alana is excited to join WeatherNation to cover weather all across the nation. If you're interested in following her on social media she can be found @alanacameronwx!

<p><strong>HIGH PLAINS</strong> - Tuesday proved to be an incredibly active day across the Central and High Plains. Storms in these parts had updrafts that exceeded 100 mph! Therefore, we were seeing hailstones that were 4.5" in diameter! That's about the size of a grapefruit. Once again, strong storms fired up Wednesday afternoon, bringing large hail and damaging winds. Wind gusts reached over 70 mph for portions of Iowa.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/plains winds-1786581631787.png"></p><h2>Overnight</h2><p>The severe threat will continue through Thursday morning. The threats we'll be tracking out here will be very similar to yesterday: damaging winds and some hail.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-12 200422-1786586713559.png"></p><p>Some storms will hold together into the overnight hours.

Repeated Severe Threat for the High Plains

How big are hailstones?  That definitely can depend on where you live and how strong an updraft the storm has that produces them!

The best way to find out how large the hail might be that fell in your yard is to take an actual measurement.

Depending on what the diameter is in inches will determine the size.
