High pressure has returned to the Southwest. Extreme Heat Warnings (in pink) have been issued for cities including Los Angeles, Phoenix, Las Vegas, Tucson, and Yuma. Heat Advisories (in orange) have been issued across the Inland Empire of California.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 081920-1787753972248.png">We started the week with plenty of triple digits across the Southwest; even Los Angeles is expected to see triple digits over the next few days! Most of the Southwest, which is normally hot, will have many cities running above average.<img src="https://media.weathernationtv.com/app/uploads/2026/08/erffffff-1787707011338.png">Los Angeles in particular is of interest because it has been nearly 2 years since we have hit the century mark. The last time LA was over 100 degrees was September 5th of 2024!<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-24 193702-1787621943327.png">The added boost in temperatures comes by way of an offshore wind known as a "Sundowner wind" which will keep things breezy overnight. That wind will also up the fire weather in the area, with an elevated threat for fire weather from the Storm Prediction Center<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 081825-1787753926904.png">

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!

<h1>ISELLE</h1>Tropical Storm Julio formed Tuesday morning in the Eastern Pacific and has now dissipated. Tropical Storm Iselle is still churning and has sustained winds of 60 MPH and is moving WNW at 9 MPH.<img src="https://media.weathernationtv.com/app/uploads/2026/08/TROPICAL STROEM ISSLEE -1787694571274.png">Waves from these systems could make it far enough north to impact the coast of southern California. Interests there should watch for a high rip current risk through the end of the week.<img src="https://media.weathernationtv.com/app/uploads/2026/08/icnreasing surffff-1787694792706.png">With multiple other areas of development, we expect additional storms to come off the factory line and move west and northwest into the Pacific. El Niño is traditionally very active for the Pacific basin, and this year has proved it. Lala continues as a Tropical Storm northwest of the Hawaiian Islands. Moke is post-tropical and fizzling out.<h1>RECAPPING LALA</h1>While Lala did not make a direct landfall on the Hawaiian Islands, it still brought significant impacts. 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 at the height of the storm. WeatherNation's field correspondent, Jonathan Petramala, was there bringing the views on the ground.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2088807962383143316" src="https://x.com/WeatherNation/status/2088807962383143316"></div>Rainfall totals exceeded 30+ inches in many locations.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 101407-1786983268612.jpg"><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2089171101914223009" src="https://x.com/WeatherNation/status/2089171101914223009"></div>As for the rest of the Pacific, we are monitoring multiple areas of interest for tropical development, including Tropical Storm Iselle. Iselle is set to remain out in open waters, but can impact wave heights and rip currents along the West Coast later this week.<img src="https://media.weathernationtv.com/app/uploads/2026/08/daaddddd-1787707557246.png">Click here for more on what is happening in the Atlantic Basin:<a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/atlantic-tropics-watching-several-areas-strong-tropical-wave-next-week"> Atlantic Tropics.</a>

In addition to the hot temperatures across the Southern and southeastern United States, there is a consistent threat of severe thunderstorms as we head through the week. On Monday, strong thunderstorms moved across the Gulf Coast, dumping some decent totals. This is in the forecast again on Tuesday.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2092024161073770640" src="https://x.com/WeatherNation/status/2092024161073770640"></div><h1>OVERNIGHT </h1>With the loss of daytime heating, storms will continue to taper off, but as the frontal boundary lingers, we have another chance of storms on Wednesday afternoon. Heavy rain will also be a concern as these storms continue. <video src="https://media.weathernationtv.com/app/uploads/2026/08/southeats-1787706303359.mp4" controls="true" width="100%"></video><h1>WEDNESDAY</h1>On Wednesday, as the main front starts to push through, portions of Arkansas, Mississippi, and Louisiana along the Mississippi River are under a MARGINAL (level 1 out of 5) risk for severe thunderstorms, mostly a damaging wind threat.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-25 035657-1787651832030.png">Locally heavy downpours are possible, which could overwhelm some saturated soils.

El Niño has been smothering tropical waves in the Atlantic this summer, with three named storms to date but only 16% of average cyclone energy! This doesn't mean the rest of the season will be just as quiet, however, as 66% of all hurricane activity in the Atlantic occurs between August 20th and October 10th.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-23 032445-1787477089898.png">Right on cue, we are seeing 2 areas of potential development in the Atlantic Basin. A tropical wave, Invest 96L, has moved off of Africa and is now in the far eastern Atlantic. In the days ahead, it may have a better chance to get its act together this week as it moves across the MDR (main development region) in the Atlantic, between Africa and the Caribbean. There is a high chance for development right now.<img src="https://media.weathernationtv.com/app/uploads/2026/08/gfs ensembllee-1787707384605.png">The two primary global forecast models are showing development late week. Both develop the system into a low, but the strength of the system varies quite a bit as the GFS deepens the low more quickly. The system is still only about halfway through the tropical Atlantic by Thursday afternoon, which means any impacts to the U.S. would be another 6-10 days out, at least.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-25 040948-1787652601439.png">Stay tuned...this is the time of the year when the Atlantic Waters can get a little rowdy. The next system to gain tropical storm status in the Atlantic will be named Dolly.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-22 081921-1787408368849.png">Stay tuned to WeatherNation for the latest in the tropics!

Strong storms came through the plains on Tuesday. Damaging winds and large hail were the main concerns. Clayton, NM saw a wind gust of 84 mph! The severe threat continues into the overnight hours and into Wednesday.<img src="https://media.weathernationtv.com/app/uploads/2026/08/fddffss-1787706914451.png">Severe chances continue into the evening and overnight hours with damaging winds and large hail as the main concern. There is a significant wind threat across the western Plains and Front Range; in blue is where we could see 75+ mph winds. In green is where we have an isolated tornado threat near the surface low in northern Minnesota and Wisconsin.<h2><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-25 081430-1787667285067.png">SPC Wednesday</h2>The severe threat continues across the Front Range once again on Wednesday<img src="https://media.weathernationtv.com/app/uploads/2026/08/more storms wedn-1787706161607.png"><h2>Forecast Timing</h2>As the front moves east, new development will be possible as we run into more daytime heating and Gulf humidity. Along the Front Range, upslope flow combined with daytime heating will help storms develop.<video src="https://media.weathernationtv.com/app/uploads/2026/08/overnissss-1787706020519.mp4" controls="true" width="100%"></video>For more info on the central regional forecast, tune into WeatherNation at :30 past the hour, every hour.
