High pressure is expected to strengthen over the coming week, bringing back extreme heat for many around the desert southwest. Temperatures are in record territory to start the weekend in Phoenix, but will get back there again in just a matter of days. In between, temperatures won't be THAT far away anyway. <img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 052612-1754134032054.jpg">High pressure this time of year means one thing: heat. Temperatures will sky-rocket as the high situates itself overhead, especially into the middle of the week. Extreme Heat Warnings are in place to cover Saturday (above) but those will get replaced with more later this week. <h1><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 052558-1754134025009.jpg">FROM BAD TO WORSE</h1>It's not bad enough to be dodging records for much of this week. The hot weather might be here to stay, with a persistent ridging setup sticking around. The Temperature Outlook from the Climate Prediction Center is circling the southern Four Corners for some above-average temps. <img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 052853-1754134361557.jpg">

Cooler air has arrived! Well, for much of the northern tier of the country, cooler air has arrived. The same front that dropped temperatures up north is pushing south into this weekend. After many were sweating out much of July, August is getting off to a better start<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 051442-1754133321766.jpg">Newark had just as many days at 100 than they did below average for the month. A cold front that produced strong storms has dropped temperatures AND humidity significantly for much of the northern half of the country (east of the Rockies anyway). Highs are expected to hang out around average for most over the next week.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 051659-1754133432716.jpg">The air behind the front is not only cooler, it's drier too! Compared to dew point temperatures in the 70s, this will give the cooler weather a much more comfortable feel. <video src="https://media.weathernationtv.com/app/uploads/2025/08/sodry-1754105193784.mp4" controls="true" width="100%"></video>The August temperature outlook looks to warm back up across most of the country, so unfortunately, this early taste of fall doesn't appear to be a sign of the trend for the first two weeks of August.<img src="https://media.weathernationtv.com/app/uploads/2025/07/1-1754017630022.png">Stay with WeatherNation for the latest.

Air Quality Alerts are in effect across a broad swath of the Midwest, impacting over 100 million Americans as thick smoke from Canadian wildfires blankets the region. States under the alert include Nebraska, Iowa, Minnesota, Michigan, Wisconsin, Illinois, and northern Indiana. Major metropolitan areas such as Chicago, Minneapolis, and North Dakota are all experiencing dangerously poor air quality conditions.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 051327-1754133216551.jpg">The front the passed through brought cooler and drier conditions, however, it also brought the winds coming down out of the North. This is the primary cause of this rapid decline in air quality, as a new wave of wildfire smoke 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 on Thursday.<video src="https://media.weathernationtv.com/app/uploads/2025/08/2025-08-02 05-15-00-1754133331768.mp4" controls="true" width="100%"></video>The Air quality index (AQI) in parts of Minnesota, Wisconsin, and North Dakota are in the "unhealthy" category for Saturday. The "unhealthy" designation on the AQI scale indicates that the air quality is poor and may pose health risks, especially for sensitive groups.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 051303-1754133191286.jpg"><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 051351-1754133242181.jpg">People with preexisting conditions such as asthma or heart disease are especially vulnerable. Health officials recommend staying indoors, limiting physical activity, and using air purifiers if available.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-01 053220-1754047973977.jpg">Conditions will gradually improve by Saturday as wind patterns shift and help disperse the smoke.

Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

While the Atlantic Basin remains quiet, an impressive Kelvin Wave (a large-scale lift zone) has recently spurred the development of numerous tropical systems in the Eastern and Central Pacific. While Keli has dissipated, it's remnants are combining with Iona to generate gusty winds and big waves around Hawaii.<h1>Central Pacific &amp; Hawaii</h1>Iona strengthened into a Category 3 hurricane Tuesday morning, with sustained winds of 125 mph, but has since weakened to a tropical storm. Since the storm formed west of 140°W, it was named through the seldom-used Central Pacific list. Iona is moving west in strong trade winds that are being enhanced by these tropical systems, prompting concerns about fire weather and generating large swells.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754105048890.png">High pressure to the north of these tropical systems is helping to spur strong winds as the pressure gradient is tight across the Hawaiian Islands. Wind advisories and red flag warnings (fire weather warnings) have been issued due to the increased risk of wildfires spreading quickly. Please avoid activities that can create a spark or flame.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754105080038.png"><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-01 051506-1754047347903.png">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. High surf is expected through Friday, with waves of 10-14 feet on south-facing shores.<video src="https://media.weathernationtv.com/app/uploads/2025/08/New Baron Video 3-1754082917663.mp4" controls="true" width="100%"></video>Tropical Storm Gil formed early Thursday morning, well to the west of Mexico. It is expected to move gradually to the WNW and strengthen to hurricane status. However, it should weaken to a remnant low before reaching Hawaii.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754105140061.png"><img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754105164234.png"><h1>Why Has the Atlantic Been So "Quiet"?</h1>Several factors are contributing to the current lull in tropical activity. One major factor is increased wind shear. Additionally, large-scale atmospheric disruptions—such as a displaced Hadley cell—have resulted in more sinking air over the tropics, which suppresses storm formation. Saharan dust and slightly cooler ocean temperatures in some areas are also playing a role.<h2>Saharan Dust</h2>Forecast models show dust plumes from Africa failing to make it across the Atlantic. This is significant because tropical systems thrive on moisture, and Saharan dust can dry out the atmosphere.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754105199580.png"><h2>Ocean Temperatures</h2>In what is known as the Main Development Region (MDR), sea surface temperatures have been a little cooler than the record-breaking pace they've been on the last two seasons (23' &amp; 24'). Tropical systems typically need sea surface temperatures of 80° at a depth of 150 ft for tropical formation. Currently, in the MDR, our temperatures are in the high 70s. We are slowly seeing some SSTs climbing to around 80°.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-28 082413-1753712658733.png">In fact, a lot of the season, in comparison to last year and the year before, has been a bit cooler. However, if you look at the numbers, it's been hovering around normal.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-22 142616-1753216233169.png">So what is actually normal? If we look only at the number of storms, it appears we're ahead of schedule. However, accumulated cyclone energy (ACE) in the Atlantic is less than 20% of normal for this point in the season.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-22 143043-1753216287218.png"><h1>Looking Ahead</h1>This early in the season, we're still trend spotting. Without a persistent El Niño setup to bring additional shear, we watch the water temperatures. In the Main Development Region, waters had been trending cooler - not anymore. Over the past few weeks, a noticeable spike in Ocean Heat Content has caused those temperatures through the column to average. Will this lead to a tropical wave developing into an organized system this week? It might, but the hostile conditions in the Atlantic won't give it much time, so the odds are not looking great.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-29 135539-1753819091494.png">

NORTHEAST - Record high temperatures broke in the northeast Wednesday afternoon, including Islip, LaGuardia, Atlantic City, and Bridgeport. Now, a cold front will tap into the high heat to create intense rainfall rates that could lead to significant flash flooding before cooler and drier conditions take over for the weekend.<h1><img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-30 191941-1753924917036.png">Flood Risk</h1>Earlier, the Moderate Risk of flooding verified with numerous reports of flash floods from D.C. to New York City!

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!
