A frontal boundary stretched across half of the country will continue to bring episodes of severe thunderstorms and heavy rain as it stalls out. Significant hail has impacted Texas over the last few days, and Thursday was no different. Hail up to the size of grapefruits was produced in severe storms earlier this afternoon! This pattern will continue again Friday.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-01 172218-1746141745197.png">FRIDAY SEVERE OUTLOOK<img src="https://media.weathernationtv.com/app/uploads/2025/05/PIC 1-1746190095625.jpg">Showers and storms were already going in the south this morning and that pattern will continue for Friday afternoon and evening.<video src="https://media.weathernationtv.com/app/uploads/2025/05/FORECAST-1746190303473.mp4" controls="true" width="100%"></video>The combination of repeated rounds of thunderstorms, especially earlier in the week, has left soils saturated in portions of eastern Oklahoma, northeast Texas, and western Arkansas. More heavy rain and flooding is possible with these future storms.<img src="https://media.weathernationtv.com/app/uploads/2025/05/1-1746154545238.png"> For the latest information, tune into WeatherNation!

A huge digging upper level low is heading from the Pacific Ocean down into the Southwestern United States this weekend into next week. As the upper low moves onshore, it will bring an unsettled pattern to the West and drop high temperatures down big time. <img src="https://media.weathernationtv.com/app/uploads/2025/05/1-1746155887272.png">Cities like Phoenix and Las Vegas will see temperatures dip below normal this weekend by at least ten degrees. I could imagine getting a break from the typical warmth this time of year is great news for the residents.<img src="https://media.weathernationtv.com/app/uploads/2025/05/1-1746155917470.png"><img src="https://media.weathernationtv.com/app/uploads/2025/05/1-1746155595056.png">On the precipitation side of things, the Southwest will scattered showers and storms and some snow showers starting this weekend and lasting into next week. Some severe chances could be possible across the Eastern Plains of Colorado early next week. In addition, some heavy rain could cause some isolated flooding too. For the higher terrains, this event could bring in some much needed snow to keep the ski resorts open a little while longer across parts of the Rockies and Sierra. Keep up with the forecast as amounts will likely change daily.<img src="https://media.weathernationtv.com/app/uploads/2025/05/1-1746155807490.png">

Louisville is gearing up for the 151st Kentucky Derby this Saturday at Churchill Downs, but weather conditions leading up to the big race could put a damper on some of the festivities.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-30 050024-1746010833872.png">Unsettled Weather Ahead of the Derby&nbsp;A series of popular events, including the Kentucky Oaks on Friday, are set to draw large crowds. However, showers and thunderstorms are expected to move through the area throughout the week, potentially impacting plans.<video src="https://media.weathernationtv.com/app/uploads/2025/05/New Baron Video 3-1746154870676.mp4" controls="true" width="100%"></video>Derby Day Outlook: A Break in the Clouds&nbsp;Fortunately, the forecast improves as we head into Saturday. While some lingering showers may still be around in the morning, forecasters expect any rain to clear out by midday. This should allow time for the Churchill Downs track to begin drying out ahead of the Derby’s scheduled post time at 6:57 p.m. ET.&nbsp;Still, after a soggy week, conditions underfoot are unlikely to be ideal. Do not expect the fast track surface seen in recent years—this year could see slower, wetter conditions like 2019, when a "sloppy" track followed light rainfall, or even 2018, which saw more than 3 inches of rain on race day.&nbsp;Cooler Temperatures in the Mix&nbsp;Behind the departing rain, cooler air will settle in. Saturday's highs are expected to stay in the 60s, a touch below average for early May but comfortable for racegoers dressed for the occasion.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-30 205908-1746068359193.png">Heading to Churchill Downs this week? Pack an umbrella and prepare for changing conditions. While Derby Day looks mostly dry, the lead-up could be a wet one.Now the fun part, how will this weather affect the horses? From blazing sunshine to torrential rain, the conditions on Derby Day can significantly influence the race's outcome and the experience for horses, jockeys, trainers, and fans alike 🏇🏇 Precipitation: Track conditions are the most immediate and noticeable way weather affects the Derby. Rain can quickly turn the usually fast dirt track into a sloppy or muddy surface, altering the performance of certain horses and jockeys. Some horses, known as “mudders,” thrive in wet conditions, while others struggle. For instance, in the rain-soaked 2019 Derby, the muddy track played a role in a dramatic finish that included the controversial disqualification of Maximum Security. Handicappers and bettors pay close attention to forecasts, knowing that a change in weather could shift the odds significantly.🏇 Temperature is another critical factor. A warm &amp; humid race day can drain a horse's stamina, especially those not acclimated to the heat and humidity. Trainers often adjust their preparation and hydration strategies depending on the expected weather. Cooler temperatures, on the other hand, may benefit certain horses with more endurance and less speed.🏇 Wind also plays a subtle but real role in racing dynamics. A strong headwind down the backstretch can tire front-running horses earlier than expected, while a tailwind might benefit late closers. Though less obvious than mud or rain, wind direction and speed can change race strategies and even alter the pace of the race.In a race where every fraction of a second matters, weather isn’t just a background variable—it’s a potential game-changer. Whether the sun is shining or rain is pouring, the conditions on Derby Day can leave a lasting imprint!

Karissa is the Director of On-Air Operations at WeatherNation. Karissa grew up loving math and science, but really fell in love with Meteorology while attending the College of DuPage in Glen Ellyn, Illinois.

Standing in front of a thunderstorm and feeling the cool outflow knock her over was an experience she will never forget. After two years at COD, she transferred to Metropolitan State University of Denver. Karissa graduated Magna Cum Laude with a Bachelors of Science in Meteorology. Her high school and college speech and meteorology professors were extremely supportive and pushed her to succeed. Before joining the WeatherNation team, she previously worked as the Morning Meteorologist at KCAU-TV in Sioux City, Iowa and at WMBD-TV in Peoria, IL. She recently was part of a National Edward R. Murrow award winning team for breaking news for their coverage of the EF-4 tornado in Washington, Illinois. In her free time, Karissa enjoys cooking and trying new foods.

Olaf formed Wednesday morning off the coast of Mexico with sustained winds at 40 mph. The storm increased to a Category 2 Hurricane before making landfall in Baja of California. Strong winds, surge and dangerous surf are impacting Cabo San Lucas as Olaf churns along.

https://twitter.com/WeatherNation/status/1436056821417005063

At the latest update, Olaf has weakened to Tropical Storm strength, but is still impacting Baja California.

<img class="alignnone size-full wp-image-155784" src="https://media.weathernationtv.com/app/uploads/2021/09/olaf-2.jpg" alt="" width="1920" height="1080" />

&nbsp;

Tropical alerts have been downgraded slightly to Tropical Storm Warnings the southern/central portions of the Baja Peninsula as tropical storm &amp; hurricane force wind gusts are likely along with high surf.

<img class="alignnone size-full wp-image-155783" src="https://media.weathernationtv.com/app/uploads/2021/09/tropical-alerts.jpg" alt="" width="1920" height="1080" />

&nbsp;

The current path of Olaf moves it slowly away from Baja California as a Tropical Storm. Expect impacts to the peninsula through Saturday morning. The storm will then move over open waters this weekend, moving west-southwestward and weakening.

<img class="alignnone size-full wp-image-155746" src="https://media.weathernationtv.com/app/uploads/2021/09/Olaf-fan.jpg" alt="" width="1920" height="1080" />

Olaf is the fifteenth named storm of the Eastern Pacific Hurricane Season. There is another area of interest off the coast of Mexico which could become our 16th named storm, Patricia. Development with this system is possible later this weekend or next week.
