Thursday afternoon, two areas of investigation in the Eastern Pacific were determined strong enough and organized enough to be named. Tropical Storms Karina and Lowell are now being tracked as they slowly track west and northwest through the weekend. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-27 150231-1787864588449.png">With unseasonably warm ocean waters in the EPAC, both of these storms will likely become hurricanes on Friday. We'll have to watch how close they get to one another to see if they have any impact. Good news is, they are expected to stay away from land for the short term. We will keep an eye on Hawaii later next week to see if any additional rainfall heads their way.

As a front moves through, expect more storms during the evening. All modes of severe weather are possible, but damaging winds and tornadoes are the primary threat. While things are likely to lighten up a bit overnight, another area of low pressure will trace the coast Friday. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-27 085120-1787842388650.png"><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-27 085138-1787843178007.png">Isolated spin-ups can't be ruled out in the I-95 corridor. The green shaded area above shows that the tornado threat is not huge, but not zero. <video src="https://media.weathernationtv.com/app/uploads/2026/08/nebams-1787862736614.mp4" controls="true" width="100%"></video>What's of some concern is the fact that rain started early and is slow to back off in the evening. And it looks like it will be coming down at a decent clip, too. Some areas could pick up more than 3-4 inches of rain, more than enough to lead to flooding by the evening commute.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 095257-1787759591325.jpg">We will have more updates on this risk all day on Thursday, so make sure to tune in to WeatherNation for the latest on Thursday's severe storm threat.

Thankfully the hail was small for the Denver metro but in WY hail reports came in up to 2" in diameter. The severe threat continues into the next few days as upslope flow fires up more troublesome storms.<h2>THURSDAY</h2>New development will be spread across the high country and into the plains as we run into more daytime heating and Gulf humidity. Along the Front Range, upslope flow combined with daytime heating will help storms thrive. We expect additional severe storm chances through Thursday night through the I-25 corridor in Colorado. A warm front draped across Nebraska will give us a better chance at stronger storms. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-07-07 042628-1787844505902.png">Like Wednesday, damaging hail will be a significant threat for the entire risk area. The front in Nebraska will lend itself more towards damaging winds. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-27 141055-1787861473544.png">This is much needed rain for Denver and Colorado, but the front range can't seem to get a break.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-07-07 043355-1787844677808.png">However, a pattern change is in the forecast.

Significant Winds and Hail Possible for the Plains

Tropical Storm Dolly has formed in the Atlantic. Former Invest 96-L was able to create a clearly defined center of circulation Thursday morning with robust convection. The two primary global forecast models agree on it moving through the MDR (main development region of the Atlantic) into the weekend. It will likely stay around tropical storm strength for much of its life cycle. Though the waters of the Atlantic are warm, there is a considerable amount of shear working against Dolly's strengthening. It will likely move through the Northern Lesser Antilles, Virgin Islands and Puerto Rico.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-27 085917-1787843282078.png">Puerto Rico has seen dire drought conditions and is in desperate need of rain. Hopefully, we can see some decent rainfall out of Dolly for them, without the strong, damaging winds. Still, with dry ground and hilly terrain, flash flooding will be a threat. Interests in the Lesser Antilles, Virgin Islands and Puerto Rico should stay updated on the forecast in the coming days. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-27 090723-1787843259511.png"><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-27 090728-1787843259514.png">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. The climatological peak of Atlantic Hurricane Season is September 10.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-27 090839-1787843332378.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!

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 192300-1787793786105.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/Screenshot 2026-08-26 192316-1787793800854.png">There are Red Flag Warnings in place for parts of Southern California. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 192331-1787793821104.png">Stay tuned to WeatherNation for the latest.
