CENTRAL U.S - A trough pushing in from the west has been responsible severe storms across the High Plains since this weekend. As of Monday, after Sunday's event, North Dakota has set a new record for the year with over 62 tornadoes! Over the next few days, we can see more rounds of severe weather, but hopefully away from North Dakota.Related: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/north-dakota-breaks-yearly-tornado-record">Dakota Tornado Record Falls Over the Weekend</a><img src="https://media.weathernationtv.com/app/uploads/2025/09/web1-1758046360328.png">As storms fire along a cold front, being ushered through the plains by our trough, they'll quickly become severe in the early afternoon. The area of greatest concern is centered on North Platte, NE but could stretch as far north as the arrowhead of Minnesota. Damaging winds and large hail will be the primary concerns, but a few tornadoes will be possible.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-16 094607-1758037770141.png">Over the next 5 days, multiple inches of rain will be possible over already saturated grounds. We have seen flooding across portions of the Northern Plains, and this threat will continue through this week. Today alone, some isolated locations will pick up 4-5 inches!<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-16 095034-1758037858814.png">Always use caution with flood waters, as you never know how deep the water is. Turn Around, Don't Drown.

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.

While the Atlantic has been relatively quiet this season, the Eastern Pacific has been much more active, particularly in recent months. Early Saturday morning, Mario dissipated southwest of the Baja Peninsula, only to reemerge Sunday morning as a tropical storm. One other tropical wave has a low chance of developing over the next week.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-15 184318-1757983404971.png"><h1>Monitoring Mario</h1>Mario formed on Friday only to dissipate on Saturday before reorganizing into a tropical storm again on Sunday! Since Mario's circulation remained intact, despite a lack of storm activity, the system did not get a new name. The latest update has Mario moving over cooler waters.<img src="https://media.weathernationtv.com/app/uploads/2025/09/web1-1758045785854.png">Mario is expected to drift WNW, eventually sending some of its moisture into Southern California by mid-to-late week, possibly leading to flooding. No direct impacts are expected from this system in the United States.<img src="https://media.weathernationtv.com/app/uploads/2025/09/web2-1758045849688.png">Forecast models project that some of Mario's moisture may reach Southern California later this week.<video src="https://media.weathernationtv.com/app/uploads/2025/09/09-15_rsw mario-1757983442769.mp4" controls="true" width="100%"></video>

Eastern Pacific: Mario Returns, Sends Moisture to California

We've got a low-pressure system out over the open waters, sitting on the warm Gulf Stream waters in the middle of September. Sounds like tropical mischief, right? While nothing is expected to gain tropical characteristics over the next day or so, we could still have mischief.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-15 091914-1757949628000.png">We spoke with Erik Heden, Warning Coordination Meteorologist at the NWS Newport-Morehead City Monday morning, about the wind, rain, and coastal flooding impacts of the latest low-pressure system to impact their region.<div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/U5nP1TmiWMg" start="0"></iframe></div><h1>Forecast Rainfall</h1>Arguably, the biggest impact of this low spinning onshore will be the rainfall, especially where it falls, with many of the highest totals concentrated in North Carolina and Virginia.<img src="https://media.weathernationtv.com/app/uploads/2025/09/web1-1758046170285.png">An excessive rainfall outlook has been issued through Tuesday for rainfall totals upwards of 3-5" with localized maximums being even higher.<h1>Severe Outlook</h1>As some of these storms get rotated onshore, there is a possibility that one or two of them will start to spin. We see this often with lows that move from water to land. The added friction with the land can be all it takes. The Storm Prediction Center is watching an area from North Carolina to Virginia with a low-end tornado threat.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-16 095425-1758038081387.png"><h1>Forecast Winds</h1>It might not be "tropical," but the highest wind gusts could approach tropical-storm-force at times. It looks like it might not be the wind that causes a ton of problems, but the direction of the wind: coastal flooding and rip current risks could pose some dangerous problems at times. Coastal inundation is only expected to approach a foot or two in low-lying, susceptible areas of the coast but the rip current risk is high along the shorelines.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-16 095512-1758038124243.png">

Did you see them? Many might have had better things to do this weekend but if you were paying attention to Space Weather, you got a treat! NOAA's Space Weather Prediction Center upped the expectation late last night, with some dazzling results.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1967422118729273403" src="https://x.com/NWSSWPC/status/1967422118729273403"></div>The problem for many in the plains was cloud-cover, with evening storms making it difficult to see the lights behind the lightning, but some were lucky to sneak between the clouds.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-15 092335-1757950156965.png">Granted, it might have been difficult to see with the naked eye. Many of the photos we've seen have mentioned a long exposure that was needed to see the fun. Either way, it's gorgeous if you can figure it out.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-15 092324-1757950271340.png">While it wasn't the most robust solar storm we've seen in the past 2 years, it was well worth it for some! We're not expecting another show, however.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-15 134825-1757965711698.png">

Grab the pumpkin spice and apple cider donuts, fall foliage is started to grace some areas across the United States, with more developing this week! The latest forecast from <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.explorefall.com/fall-foliage-map">Explore Fall</a> (top of page) shows developing color across the Rockies, Cascades, High Sierra, and the Upper-Midwest, near the Canadian border, over the next seven days (September 8th - 14th). Recent wildfire activity in the Sierra may make color there a bit more muted or highly variable between patches of trees. <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-08 104753-1757350314424.png">Color has already been showing some for areas in the map above (yellow areas), mostly in the Rockies and Cascades. In fact, we've seen the Bigtooth Maples change quite a bit in the Wasatch Mountains near Salt Lake City!<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1964055938010067402" src="https://x.com/WeatherNation/status/1964055938010067402"></div>The most 30 days prior to the appearance of fall color are the most important for vibrancy during the peak season, but drought conditions can also lead to more muted color or variable conditions. <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-08 105237-1757350392233.png">For great fall color, sunny days with cool, crisp nights are preferable. Though rain is welcome at times to keep the trees from drying out.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-08 105303-1757350398827.png">

Fall Color Starting to Show In Parts of the Lower 48

A strong upper-level trough along with monsoonal moisture advecting northward continues to hone in on Western Colorado, SE Utah, and New Mexico. Both a flood threat and isolated severe thunderstorms will be possible. There are risks for excessive rainfall and flooding over the next few days. The risks are very isolated in the threat of flooding, but it is still something to pay attention to.<video src="https://media.weathernationtv.com/app/uploads/2025/09/09-14 rsc wpcs-1757878358375.mp4" controls="true" width="100%"></video>The Storm Prediction Center has the risk for strong storms stretching from North Dakota to Texas, but here we will discuss the threat for the southern Plains and Texas.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-14 133029-1757878277064.png">The latest model data suggest that the heaviest rain will be focused over parts of West Texas and the Central Plains as the disturbance keeps moving east. With upper-level support, some thunderstorms may become organized with a severe threat. Straight-line damaging winds would be the main hazard through the weekend but a few tornadoes are possible.<video src="https://media.weathernationtv.com/app/uploads/2025/09/09-14 rsc-1757878300010.mp4" controls="true" width="100%"></video>Stay with WeatherNation for the latest updates.

Severe Storms Look More Likely This Afternoon

Surprisingly, this isn't about football. Or at least not how you would think.<h1>OMEGA BLOCK</h1>In meteorology, the dog wags the tail, not the other way around. Meaning the upper levels have more influence on the day-to-day weather. When we look at the upper atmosphere, an important shape forms: the Greek letter omega! An Omega Block is a type of stagnant flow that isn't in a hurry to change.READ MORE: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/what-is-an-omega-block">What is an Omega Block?</a><img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-11 095812-1757606300377.png"><h1>WHAT DOES THIS MEAN</h1>The two dips in the overall flow will harbor low pressure: one on each side of the lower 48. That will keep the stormy skies nearby and for the East Coast, the cooler weather as well! But what about anyone under the high? Here comes some late Summer heat! St. Louis started off the month on a cooler note, but lately the thermometer has been rising. <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-13 205359-1757818447010.png">Temperatures are expected to continue to climb Sunday, eventually entering record territory in places like St. Louis.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-13 205604-1757818571864.png"><h1>I'M HERE FOR FOOTBALL</h1>Well, here's your tie-in: football practices could become a little more dangerous over the coming week. This might become a recurring theme throughout September, despite the comfortable start we had. The Climate Prediction Center is leaning toward above-average temperatures well into September.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-11 100752-1757606949368.png">
