<p><strong>Air Quality Alerts</strong> are in effect across a broad swath of the Midwest and Northern New England, impacting many Americans as thick smoke from Canadian wildfires blankets the region. The worst of the air quality is found in the Great Lakes. <img src="https://media.weathernationtv.com/app/uploads/2025/08/web 8-1754312892237.png">A new wave of wildfire smoke is drifting southward from multiple blazes burning across the Canadian provinces of Saskatchewan, Alberta, and Manitoba. These fires have been active throughout the summer, and this is not the first time their smoke has reached the U.S. This latest plume began sweeping into the Upper Midwest last Thursday and still lingers this week.</p><video src="https://media.weathernationtv.com/app/uploads/2025/08/fda-1754335948249.mp4" controls="true" width="100%"></video><video src="https://media.weathernationtv.com/app/uploads/2025/08/smokeysee-1754335958812.mp4" controls="true" width="100%"></video><p>The Air Quality Index (AQI) in parts of Wisconsin, Michigan, and the Northeast is in the "unhealthy" category. The "unhealthy" designation on the AQI scale <span style="color: rgb(0, 29, 53)">indicates that the air quality is poor and may pose health risks, especially for sensitive groups</span>.

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!

<p>After getting off to a record fast start with named systems, the Atlantic Basin has been largely quiet over the past month, but things are changing. We have two areas of interest we are watching, and as of Sunday night, we have Dexter. Tropical Storm Dexter has formed in the Atlantic. Current maximum sustained winds are 45 mph, and this system is currently moving NE at 14 mph. Dexter is forecast to move away from the U.S. coast.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-04 070922-1754312972669.jpg"><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-04 071024-1754313031841.jpg">Wave heights can be impacted by this system. We can see some offshore waves between 5-10 feet. There's a seperate area of low pressure that could break off and spin towards the coast late this week. The chances of development are still low at this point.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-04 071310-1754313203404.jpg">Late Saturday evening, the National Hurricane Center highlighted a new area to watch!

<p>Strong winds in the upper levels of the atmosphere. This time of year, storms are easy to come by around the foothills of the Rocky Mountains, but strong jet stream energy is going to try to organize them. We saw how well it can organize storms last week, with a tornado-warned storm dropping baseball-sized hail in Cheyenne, and softballs in Kansas Sunday night.</p><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1952391580163207320" src="https://x.com/WeatherNation/status/1952391580163207320"></div><h1><br>Upper Level Set-Up</h1><p>Severe storms will remain in the forecast as the jet stream energy remains elevated around the strong ridge of high pressure in Arizona. As storms fire up around the Rockies, the jet stream energy will help organize storms and carry them to the east into the Plains, where they'll be able to strengthen.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/08/Web 1-1754309526598.png"></p><h1>Severe Weather Outlooks</h1><p>Isolated severe storms will remain in the forecast this afternoon and Tuesday as a new low-pressure system is moving out of the Northern Rockies.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/08/throughtod-1754334590552.png"></p><h1><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-04 113418-1754328869539.png"><img src="https://media.weathernationtv.com/app/uploads/2025/08/Web 5-1754310637375.png"></h1><h1>Forecast Timing</h1><p>Expect storms to peak with daytime heating.

<p>After a week of relentless heat, a frontal boundary has cut into high pressure across the South, dropping temperatures but also spurring rounds of heavy rain. Flooding is likely for some areas across the South into the work week.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-03 065121-1754225716471.png"></p><h1>Forecast</h1><p>As the stalled front sits near the I-10 corridor, rounds of storms are expected to pop-up on either side of the front for the next few afternoons, with the heaviest rain beginning to shift north by Tuesday. Pockets of 5-8" of rain could accumulate in some areas, likely leading to flooding and/or flash flooding. Seek higher ground if a flash flood warning is issued.</p><video src="https://media.weathernationtv.com/app/uploads/2025/08/08-04 rse-1754333473284.mp4" controls="true" width="100%"></video><p>Flood watches remain in effect into Tuesday.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-04 074652-1754315221139.png"></p><h1>Cooler Air</h1><p>A wedge front is also following the storms across the Southeast, leading to below-average temperatures from the Carolinas to the west.

<p>An impressive Kelvin Wave (a large-scale lift zone) has recently spurred the development of numerous tropical systems in the Eastern and Central Pacific. Gil continues to churn west as a post-tropical system, and there are a couple more areas of potential development on its heels.</p><h1>Hawaii</h1><p>As systems have been moving south of the island chain, winds have been increasing at times in response. Red Flag Warnings remain in effect through Sunday afternoon.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 204134-1754188981193.png"></p><p>It has been quite dry across much of the Hawaiian Island chain, with several areas in severe to extreme drought conditions. This means vegetation is dry enough to burn quickly in a fire. The higher winds are also creating big swells, which should gradually drop over the weekend.</p><h1>GIL</h1><p>Gil formed early Thursday morning, well to the west of Mexico, and is continuing WNW. Gil is now a post-tropical cyclone, and this is the final NHC forecast cone that will be released. A gradual decrease in forward speed is expected. Additional information can be found in the High Seas Forecast by the National Weather Service.</p><h1><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-03 135002-1754250641715.png">Looking Ahead</h1><p>There are a few other areas to watch behind Gil, forecasted to have more of a westward path, it appears. One is expected to develop in the next week, while the other is a coin toss. The next two names on the list are Henriette and Ivo.</p><p><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-03 134853-1754250745342.png"></p>

<p>Cooler air has arrived! Well, for much of the <em>northern tier</em> of the country, cooler air has arrived. The same front that dropped temperatures up north is pushing south into this weekend.
