A frontal boundary stretched across the half of the U.S. will continue to bring episodes of severe thunderstorms and heavy rain as it stalls out. The Central U.S. will get the brunt of the severe weather on Wednesday &amp; Thursday, before shifting into the Midwest, Ohio Valley, and Great Lakes by Friday. &nbsp;A severe thunderstorm watch has been issued for the northern Texas and Southern Oklahoma as storm continue to remain across the region Wednesday morning.<img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-30 050934-1746011384307.png">While the most intense storms from Wednesday morning are expected to diminish, another round of severe weather across the south-central U.S. by the afternoon is possible. The threat for damaging winds, large to very large hail, and tornadoes will remain in play.&nbsp;The Storm Prediction Center has issued an Enhanced risk (level 3 out of 5) for the metro of Dallas, TX.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-30 043436-1746009281759.png"><img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-30 050508-1746011139367.png">As mentioned, Wednesday Morning, a significant threat for severe weather remains, as storms move through northern Texas and Oklahoma. These storms from overnight are also known as a mesoscale convective system (MCS). This system could bring damaging winds, hail, and a few tornadoes as it moves east across western Oklahoma.&nbsp;&nbsp;<video src="https://media.weathernationtv.com/app/uploads/2025/04/2025-04-30 04-35-01-1746009343128.mp4" controls="true" width="100%"></video>By late morning through early afternoon the threat will shift into the Mississippi &amp; Ohio Valleys. Scattered thunderstorms capable of producing damaging wind and hail will be possible. The afternoon heating and rich moisture will combine with weak but sufficient wind shear near a surging dryline, potentially allowing isolated supercells to develop in Central Texas. These storms may produce very large hail and strong wind gusts.&nbsp;<video src="https://media.weathernationtv.com/app/uploads/2025/04/2025-04-30 04-36-07-1746009402972.mp4" controls="true" width="100%"></video>By Thursday the storms will reach the Great Lakes and the Northeast. Scattered thunderstorms will reach as far north as New England. While the severe threat is expected to lessen compared to earlier in the week, some embedded strong storms may still occur, particularly in areas where instability persists. A Slight risk is issued for Friday (level 2 out of 5). The threats for Thursday include gusty winds, localized heavy rainfall, and a hail risk.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-30 043658-1746009428373.png">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. Though the severe threat shifts east, residual flooding concerns may continue into Thursday in these areas before drying out.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-30 043843-1746009538378.png">For the latest information tune into WeatherNation.&nbsp;

The weather pattern remains favorable for heavy rain in the southern plains through Thursday. The area is still recovering from the heavy rain last weekend, meaning flash flooding could become a big concern, especially after widespread totals of 1-2" with the morning round of storms Tuesday, completely saturating the top layer of soil. Oklahoma City was under a Flash Flood Warning Tuesday AM with reports of creeks overflowing and basements flooding. The National Weather Service has issued a FLOOD WATCH into Thursday morning across portions of Oklahoma, Arkansas, Missouri, Kansas, and Texas.Models have begun to align on the location of where this stationary boundary stalls out mid-week. Heavy rain will likely be the result of strong/severe storms.

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 Winsday on Wednesday, Thurby on Thursday, and 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.&nbsp;<ul><li>Wednesday: Scattered showers and thunderstorms are possible, especially in the afternoon.&nbsp;</li></ul><ul><li>Thursday and Friday: Rain chances remain elevated, with Friday’s Kentucky Oaks race particularly at risk for wet weather disruptions.&nbsp;<video src="https://media.weathernationtv.com/app/uploads/2025/04/2025-04-30 04-58-34-1746010848859.mp4" controls="true" width="100%"></video></li></ul>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 045947-1746010804748.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.

Severe storms dominated portions of the southern plains, Midwest, and northeast today, and a severe threat remains in place overnight from Burlington, Vermont, down through San Angelo, Texas.<h1>SOUTHERN END</h1>Strong updrafts provided the support needed in the atmosphere to grow large hailstones. We saw large hail today in Texas. Hailstones reached 5 inches in Guthrie, Texas. To put that into perspective, that is the size of a DVD!! In Girard, Texas hailstones reached 4 inches, the size of a softball. Both of these sizes can cause major damage!<img src="https://media.weathernationtv.com/app/uploads/2025/04/texas haillff-1745975175422.png">A significant severe threat remains overnight for portions of Texas and Oklahoma. Wind gusts of 75+ mph are possible, and the large hail threat will continue.<img src="https://media.weathernationtv.com/app/uploads/2025/04/overnighttttd-1745976180451.png"><h1>NORTHERN END</h1>An isolated tornado risk remains in place overnight for cities like Cleveland, Syracuse, and Buffalo. Storms and this threat will taper off through the overnight hours in the Northeast, but anything that lingers will have the potential to be strong to severe.<img src="https://media.weathernationtv.com/app/uploads/2025/04/overnight tor risk-1745976238745.png"><h1>TIMING</h1>Thunderstorms continue ahead and along this cold front, producing all threats of severe weather, including tornadoes, hail, and damaging winds. While storms wind down tonight in the northeast, they will continue cranking in the southern Plains of Oklahoma overnight and into Wednesday morning.<video src="https://media.weathernationtv.com/app/uploads/2025/04/eeeewww-1745976383462.mp4" controls="true" width="100%"></video>

A strong area of low pressure has emerged from the Rockies, which has prompted a MODERATE (level 4 out of 5) risk overnight. EF-2+ intensity tornadoes and 2-inch diameter hail (or larger) are possible.CAUGHT ON CAMERA: Our field correspondent Erik Fox was in the Sand Hills of Nebraska, where a storm cycled for hours on Sunday night, producing the spotting of a tornado.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1916681281515184498" src="https://x.com/WeatherNation/status/1916681281515184498"></div><h1>Overnight - Hazards and Timing</h1>The Storm Prediction Center has issued a MODERATE (level 4 out of 5) risk for severe storms in portions of the Upper Midwest and Upper Mississippi Valley. Multiple corridors of severe thunderstorms remain possible.<img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-28 212044-1745896851475.png">Strong winds and massive hail remain possible, but the tornado threat will also be quite high for portions of the Upper-Midwest, thanks to increased wind shear near the upper-level low. This includes the potential for significant tornadoes in the Upper-Midwest, meaning we could see violent tornadoes that last for a long duration. These tornadoes should be taken very seriously, as they'll have the potential to produce winds over 110 mph (EF-2 or greater).<img src="https://media.weathernationtv.com/app/uploads/2025/04/Screenshot 2025-04-28 212227-1745896953253.png">Storms have developed and will continue into the overnight hours..

Wild developments have surfaced from the state of California after local authorities arrested a man believed to be tied to the Park Fire. He pushed a burning car into a ditch, that started the blaze on Wednesday, July 24. The day it started, it grew over 124,000 acres with little containment. Now, the fire is <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.fire.ca.gov/incidents/2024/7/24/park-fire">burning more than 399k acres</a>. The fire is burning across Butte and Tehama County, north of Chico. According to CalFire, the fire continues to burn very actively in steep terrain, which has made it difficult to access for firefighters.Related article: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/Wildfire%20Smoke%20Impacting%20Air%20Quality%20Across%20the%20West,%20Central%20U.S.">Wildfire Smoke Impacting Air Quality Across the West, Central U.S.</a><img src="https://media.weathernationtv.com/app/uploads/2024/08/1-1722656433076.png">The map below shows the Park Fire's recent activity which started after a burning car was pushed into a gully. On Wednesday, it was sparked and began moving to the north of Chico (red). Then Thursday (dark orange) it burned to the north. Friday (orange) the fire burned to the east and northwest. Saturday (light orange), the fire burned toward CA Highway 44. Then on Sunday and Monday (mustard to light yellow), more flames engulfed Highway 44 and reached farther east into the Plumas National Forest. Tuesday (lightest yellow) headed towards Mineral and Prattville.<img src="https://media.weathernationtv.com/app/uploads/2024/08/1-1722626545687.png">Within the first five days, the Park Fire grew to become one of California's largest wildfires on record. On Friday, August 2nd it surpassed 399,000 acres, making it the 4th largest wildfire in California state history. The largest wildfire (or group of fires) was the August Lightning Complex fires in northern California in 2020, when more than a million acres of land was scorched.<img src="https://media.weathernationtv.com/app/uploads/2024/08/1-1722626651028.png">We're entering the hottest time of the year in this part of the country, which could continue drying vegetation and making it conducive for fire starts. Prevent future fires by obeying burn bans, avoiding anything that sparks, and properly disposing of anything lit on fire. We will continue to update you on this developing story.
