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.

Another intense night of severe storms ripped through portions of the Upper-Midwest from Thursday night into Friday morning. Multiple bowing segments congealed into a large complex/squall line, which produced wind damage for over 300 miles across the states of Montana, North Dakota, and Minnesota. Thousands of households lost power while several structures have reported damage. Will this be classified as a derecho? According to NWS Grand Forks, Thursday's night storm was not classified as a derecho. Listen why.<video src="https://media.weathernationtv.com/app/uploads/2025/08/SOT_TRT.34_(audio fixed)EXPLAINING WHY THE STORMS DIDN'T MEET DERECHO CRITERIA_MS_E080825_1-1754708943137.mp4" controls="true" width="100%"></video> Again, NWS Grand Forks believes the factors of not enough higher end wind gusts, the duration of the wind event, and the coverage area was enough not to deem this event as a derecho. However, we can still learn more on what is a derecho! A big severe strength wind storm to say the least, but the Storm Prediction Center has a full definition including multiple criteria that have to be met.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-08 061237-1754655858161.png">It certainly appears this system will meet the spatial requirements for a derecho as damaging wind reports (58+ mph) stretch for over 300 miles.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-08 061159-1754655182565.png">Peak gusts were well over 75 mph, with a gust at Gran Forks Air Force Base measured at 91 mph!<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-08 061206-1754655189603.png">This squall line produced several 75+ mph gusts, which appear to be well separated as well. This also appears to meet the requirement for a derecho.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-08 061215-1754655197446.png">While it appears this system has met the basic 3 requirements for a derecho, other criteria (top of the page) have to be met as well. In addition, wind reports and reports of damage will have to be verified as accurate.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-08 061231-1754655205131.png">Derechos most often occur from the late spring through the summer, with a typical drop off in August.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-08 061246-1754655219174.png">

The Eastern and Central Pacific have had an interesting start to the season, with plenty of named storms (11 combined). This is above the average of 7, but the energy generated by these systems is only about 80% of what's typical for this time of year. Long story short, this region has had many systems, but they've been on the weaker side. That trend has continued this week with Henriette and Ivo which could bring minor impacts to nearby landmasses.<h1>Henriette</h1>On Friday, Henriette was downgraded to a remnant low as it continues to struggle in the Pacific. However, it is forecast to miss Hawaii and the strengthen again back to a tropical storm by next week.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754708604519.png"><h1>IVO</h1>Ivo is expected to remain a tropical storm as it moves away from Cabo San Lucas and Mexico. It should weaken by early next week to a depression.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754708710767.png"><a target="_blank" rel="noopener noreferrer nofollow" href="https://www.star.nesdis.noaa.gov/goes/floater.php?stormid=EP092025"> </a>Now that we have Ivo, up next on the list in the Pacific will be Juliette.<img src="https://media.weathernationtv.com/app/uploads/2025/08/tropical ivvo-1754519175244.png">We're far from the end of the Pacific Hurricane Season, with a secondary peak occurring later in September.<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-05 104202-1754412196354.png">

Tropical activity in the Atlantic has been off to a crawl to start the 2025 season. Before Dexter formed, Accumulated Cyclone Energy (ACE) in the Atlantic was less than 15% of normal. Dexter more than doubled this stat, but it's still less than 30% of a typical year, even though we may be ahead of schedule when it comes to named storms. That being said, the bulk of seasonal activity is still ahead of us, with 90% of the annual energy occurring after the first week of August. In short, we've got a lot of season ahead of us, so don't let your guard down!RELATED ARTICLE: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/csu-issues-final-2025-atlantic-hurricane-season-forecast">CSU, NOAA UPDATE Atlantic Hurricane Season Forecast</a><h2>Tropical Wave (Central Atlantic) - Invest 96L</h2>The attention-grabber is our latest wave that is moving through the MDR (Main Development Region) in the Atlantic.

A robust upper-level trough sweeping through the northern Plains Friday morning is setting the stage for a notably dynamic weather pattern for August. There were widespread wind reports over with the Grand Forks AFB clocking a wind gust of 91 mph. Storms will continue throughout the day, as there will be plenty of energy and instability across the plains. The Storm Prediction Center (SPC) has severe outlooks in place through Sunday. These storms will pose a significant threat, including the possibility of a few tornadoes, hail over two inches in size, and wind gusts over 75 mph. &nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-08 114222-1754674963936.png"><h1>OVERNIGHT</h1>As the front pushes eastward, it will tap into enough instability . There will be a risk for overnight storms and that mean residents will need multiple ways to get severe warnings.<img src="https://media.weathernationtv.com/app/uploads/2025/08/PIC 1-1754704233694.jpg"> The highest threat of severe storms should take place within the warm sector across North Dakota, Northern Minnesota, and Wisconsin.

Stay inside as these storms pass and park your car in a garage or carport, if possible as hail will be a threat too. Saturday already has a slight risk of severe weather across Wisconsin and Iowa. As the front stalls, more severe weather is possible on Sunday too.<img src="https://media.weathernationtv.com/app/uploads/2025/08/PIC 1-1754683923725.jpg"><img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754691257521.png">Alongside the severe thunderstorm potential, periods of heavy rainfall are expected to develop across parts of the Great Lakes.

Flooding has been a major weather story for the southeast recently. More heavy rain fell across parts of Georgia and Florida. More heavy rain and flooding chances will be possible into the weekend.<img src="https://media.weathernationtv.com/app/uploads/2025/08/1-1754708207482.png"><h1>Forecast</h1>As the stalled front lingers and a weak area of low pressure remains off the coast, rounds of storms are expected, with the heaviest rain possible in Florida and cities closer to the coastline.

Phoenix Breaks Monthly Temp Record, Heat Backs Off This Weekend

Thursday, <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.noaa.gov/news-release/prediction-remains-on-track-for-above-normal-atlantic-hurricane-season">NOAA issued an update</a> to their outlook for the 2025 Atlantic hurricane season. Although their numbers have adjusted down slightly, their predictions continue to foresee an above average season. This comes on the heels of <a target="_blank" rel="noopener noreferrer nofollow" href="https://tropical.colostate.edu/Forecast/2025-08.pdf">Colorado State University releasing its final forecast</a> for the 2025 Atlantic hurricane season Wednesday. The forecast team at CSU, led by meteorologist Dr. Phil Klotzbach, kept their predictions the same as July. For August, they are stuck with 16 named storms overall, with eight of those predicted to be hurricanes, and three major hurricanes.&nbsp;It is important to note that both the NOAA and CSU forecasts include the four name storms that have already formed in the Atlantic (Andrea, Barry, Chantal and Dexter). Climatologically, around August 10 the rate at which storms form and grow accelerates quickly through the peak of the season around September 11.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1953109057427939468" src="https://x.com/philklotzbach/status/1953109057427939468"></div>The reason why the forecast has not changed much, or has gone down slightly since the April, is the uncertainty across the tropics. While sea surface temperatures in both the Atlantic and Pacific are still warm, and this tends to support storm formation, upper-level winds over the Caribbean have been unusually hostile during June and July. This atmospheric setup typically suppresses hurricane development in the Atlantic basin.&nbsp;<blockquote>“Many of the factors we identified ahead of the season are still at play, and conditions are largely tracking along with our May predictions,” said Matt Rosencrans, lead hurricane season forecaster with NOAA’s National Centers for Environmental Prediction, part of the National Weather Service.&nbsp;</blockquote>RELATED ARTICLE: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/an-area-to-monitor-in-the-atlantic">Atlantic Waking Up, Eastern Pacific Staying Active</a><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-06 110050-1754499664701.png">The driving factor behind the above-average forecast remains the exceptionally warm waters across the eastern and central Atlantic Basin. Combined with a neutral El Niño-Southern Oscillation (ENSO), a state that neither strongly inhibits nor enhances storm activity, these conditions could still favor a more active season.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-06 105940-1754499600405.png">Yet, forecasters are closely watching high levels of wind shear in the Caribbean, a phenomenon involving shifts in wind direction and speed with height. This shear is known to disrupt storm development. &nbsp;CSU also warns that the U.S. coastline faces an above-average risk of at least one major hurricane making landfall this season, a reminder that even in uncertain years, coastal residents should remain vigilant.&nbsp;<blockquote>"No two storms are alike. Every storm presents unique, life-threatening hazards that can impact people in both coastal and inland communities. Have a plan in place, and know the actions you should take before, during and after the wide range of hazards that the hurricane season can bring.”&nbsp;said NOAA’s National Weather Service Director Ken Graham.</blockquote><img src="https://media.weathernationtv.com/app/uploads/2025/08/Screenshot 2025-08-06 110039-1754499698410.png">With the arrival of August, the Atlantic hurricane season is entering its most active stretch, which typically peaks around September 10. The pattern is starting to get more active in the Atlantic. Tropical Storm Dexter is still making waves (literally) in the Atlantic, and there are two additional areas to watch in the central Atlantic and off the Southeast coast.&nbsp;The Atlantic hurricane season officially runs through November 30, leaving several more months of potential activity ahead.&nbsp;Tune into WeatherNation for the latest Tropical updates.

Heavy rainfall late last week led to widespread flooding across many Southeastern states and areas as far north as the Ohio Valley.  One state hit particularly hard was Tennessee, where the governor declared a <a href="https://www.tn.gov/tema/current-status.html">Level 3 State of Emergency</a>.   Floodwaters covered roadways, people had to be rescued by emergency officials, and rivers overflowed their banks.  River levels will continue to rise this week.

https://twitter.com/TVAnews/status/1099790112261660673

Not only did river flooding and flash flooding occur, there were mudslide concerns in many of the state's mountainous areas.

https://twitter.com/WeatherNation/status/1099804936689278977

Many cities experienced record rainfall.  On Saturday alone, the city of Knoxville was inundated with over 5 inches, setting a new record for February 23rd.

<img class="alignnone size-large wp-image-104255" src="https://media.weathernationtv.com/app/uploads/2019/02/KnoxRec-728x408.jpg" alt="" width="728" height="408" />

Saturday's total pushed February's monthly rainfall up to 12.55 inches.  February 2019 is now the wettest February in Knoxville's history, surpassing a record that has stood for 146 years!  Weather records have been kept in Knoxville since 1871.

In the state capital of Nashville, a similar record was set this month.  February 2019 is now their wettest February with a total of 13.47 inches.  This surpasses a record set 139 years ago in the Music City.

<img class="alignnone size-large wp-image-104253" src="https://media.weathernationtv.com/app/uploads/2019/02/NashFeb-728x408.jpg" alt="" width="728" height="408" />

February 2019 brought copious amounts of rain to many other cities in Tennessee and the surrounding states.  The local National Weather Service office in Nashville mentioned that approximately 10 to 15 inches of rain has fallen throughout much of Middle Tennessee.

https://twitter.com/NWSNashville/status/1099738686118338560

Because of the significant rainfall, river levels are expected to remain high through the end of the month.  Record crest levels are forecast on several waterways.

<img class="alignnone size-large wp-image-104252" src="https://media.weathernationtv.com/app/uploads/2019/02/flood-alerts-1-728x408.jpg" alt="" width="728" height="408" />

Looking ahead to early March, the Climate Prediction Center paints a wetter-than-normal picture across much of the southeastern United States.
