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 Tropical Storm, and there are a couple more areas of potential development on its heels. <h1>HAWAII</h1>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. <img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 204134-1754188981193.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.<h1>GIL</h1>Gil formed early Thursday morning, well to the west of Mexico, and is continuing WNW. The storm reached hurricane status briefly, but is now back down to a Tropical Storm with further weakening expected. <h1><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 204421-1754189067298.png">Looking Ahead</h1>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.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 204339-1754189120957.png">

Tropics: Eastern Pacific Keeps Churning Out Systems

After getting off to a record fast start with named systems, the Atlantic Basin has been largely quiet over the past month. A stalled boundary spinning up an area of low pressure is trying to change that. The National Hurricane Center officially highlighted an area off of the coast of Carolina with a low-end chance to develop. Here's what we know.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754188466850.png">An area of low pressure is expected to form sometime this weekend. Once it forms, it will be traveling over some pretty undisturbed waters in the Atlantic. Temperatures on the surface out here are past 80, which would help maintain any tropical characteristics if they were to form.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 071442-1754140489886.png">If anything were to develop, it will get swept out to sea, courtesy of a high parked on top of Bermuda. That's not to say we won't see any impacts stateside, however.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-02 072228-1754140955857.png">Rip currents will likely be the biggest concern from coastal Carolina down through the northeastern portion of Florida. Waves could reach as high as 10 feet in some offshore areas late Saturday night into Sunday morning, but the wind direction is going to be what causes the rip current concern. Be sure to heed the advice of the flags on the beaches into Sunday.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754173191163.png">Late Saturday evening, the National Hurricane Center has highlighted a new area to watch! A tropical wave will move off the coast of Africa in the next day or two and there will be a window for tropical development by the middle and end of next week!<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754188776772.png">

Air Quality Alerts are in effect across a broad swath of the Midwest and Northern New England, impacting over 100 million 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/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/New Baron Video 3-1754173865147.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/2025/08/1-1754188249822.png">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.

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 this afternoon. We saw how well it can organize storms on Friday, with a tornado-warned storm dropping baseball-sized hail in Cheyenne.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1951462961404354594" src="https://x.com/WeatherNation/status/1951462961404354594"></div>Overnight storms will be capable of large hail and damaging winds. Some of those severe threats could reach the high-end side of the scale, with 75 mph+ winds possible along with egg-sized hail or larger.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754187752604.png">As complexes move out of Colorado and New Mexico, they will push into the Central Plains and TX/OK Panhandles for both tonight and again on Sunday.<video src="https://media.weathernationtv.com/app/uploads/2025/08/New Baron Video 3-1754188012091.mp4" controls="true" width="100%"></video>Guess what we're doing tomorrow. More of the same - right now the Storm Prediction Center has a MARGINAL risk for severe thunderstorms for many of the same locations.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754173469853.png">

Heat and humidity have been the topic of conversation for awhile across the southeast. Now, as a cold front moves further to the south, it is bringing some relief to the hot temperatures. However, this front is also ramping up the storms across the southeast.Dewpoints are still in the 70s, so heat indices will nearly reach 100° in Jacksonville, FL for Sunday. The moisture will also aid in heavy rainfall across parts of the southeast.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754174039175.png"><h1>FORECAST</h1>The cold front has stalled in the vicinity of the Interstate 10 corridor. With the front acting as a lifting mechanism along with the heat and humidity in place, there is the chance for a few severe thunderstorms overnight and through the weekend.<video src="https://media.weathernationtv.com/app/uploads/2025/08/New Baron Video 3-1754187618860.mp4" controls="true" width="100%"></video>As the cold front lingers, the humidity won't totally go away for parts of the Southeast despite the temperatures going down. The front will stall, and daily thunderstorms will lead to heavy rain for the next few days. By the end of the weekend, cooler temperatures will start to take over the Southeast.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754174183079.png"><img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754174206239.png">Tune into the eastern regional forecast :10 past the hour for more details.

Stormy and Slightly Cooler for the Southeast

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.

[<a href="https://cpo.noaa.gov/News/News-Article/ArtMID/6226/ArticleID/1708/New-study-elucidates-the-role-of-atmospheric-rivers-in-future-precipitation-regime-change-in-the-West" target="_blank" rel="noopener">NOAA</a>]  A new paper published recently in Scientific Reports explains the dominant mechanism for projected intensification of extreme precipitation in California and Western North America as part of the changing precipitation regime of this region. Previous work has shown the decreasing frequency of precipitation in all Mediterranean climate regions as they become more subtropical and the increasing intensity of precipitation (especially in California).

In this latest study, lead by Sasha Gershunov, with support from the <a href="https://www.adaptationclearinghouse.org/organizations/california-nevada-applications-program-cnap-risa.html">California-Nevada Applications Program (CNAP) - a NOAA RISA program,</a> the group identifies the dominant mechanism by which heavy precipitation becomes more extreme, atmospheric rivers. The results are not necessarily surprising as other studies have suggested intensification of atmospheric rivers, but the group has now explicitly linked this intensification of atmospheric rivers to changes in finely-resolved precipitation.

This more mechanistic understanding of the intensification of heavy precipitation will help scientists interpret ongoing changes and make plans to manage water resources and flood risk in a progressively more volatile future.
