Heavy rain has already lead to issues in the Lone Star State to start the week. Rich, tropical moisture has rushed northward, meeting a slow-moving boundary. That recipe has led to numerous reports of flash flooding, starting late Sunday night.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2066498460266725833" src="https://x.com/WeatherNation/status/2066498460266725833?s=20"></div>As some residents struggled to get home, they could see more issues over the coming days with flooding. The overall setup won't change much. That rich moisture will loiter around the Gulf, with another front looking to stall out through the middle and end of the week. Rounds of heavy rain will threaten the area each of the next 5 days. The Weather Prediction Center has highlighted areas from Texas to Louisiana with the greatest threat of flash flooding, issuing a MODERATE RISK (level 3 out of 4) of excessive rainfall.<video src="https://media.weathernationtv.com/app/uploads/2026/06/2026-06-15 07-18-49-1781529547574.mp4" controls="true" width="100%"></video>Rainfall amounts are expected to top seven inches in many locations, with localized areas surpassing that. Flash flooding has already been an issue - grounds are already saturated - expect more flooding over the coming days.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-15 072031-1781529664697.jpg">

Heavy Rain Overwhelms Texas

Another ridge of high pressure is parked over the Pacific Ocean. This one will send temperatures soaring well into the 90's along the West Coast both today and Monday. With Portland reaching 94 on Sunday, they've unofficially broken the record high for June 14th; the previous record was 89°. Another day of record heat will follow on Monday before it starts to cool off a touch, at least enough to get out of record territory.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 194848-1781488171431.png">Seattle was another location that broke a record high, reaching 85°, tying the previous record of 85°. Heat alerts are in place all across the West Coast through Tuesday, so be prepared for oppressive temperatures. Especially if you work outside or the kids are headed to camp this week.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-15 072904-1781530161194.jpg">It isn't just the Pacific Northwest - California will be under the grips of this high pressure as well. <img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-15 072942-1781530189642.jpg">The heat won't break until the end of the week, when temperatures cool to seasonal norms Thursday-Friday. With an extended stretch of heat, be sure to take it easy since heat-related issues can compound throughout a week.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-15 073031-1781530237987.jpg">

Alana Cameron was born and raised in Canada in the city of Mississauga, just outside of Toronto. Alana is the oldest of 4 siblings, all close in age, and grew up playing outside with them in all types of weather. After graduating high school, Alana moved to study at the University of British Columbia in Kelowna for a year before transferring to Dalhousie University in Halifax, Nova Scotia where she completed a Bachelor of Science in Physics and Atmospheric Science. Upon completion, Alana moved back to Toronto where she completed a post-grad degree in Meteorology at York University. After her post-grad, she went on to complete another post-grad in Broadcast Journalism - TV News at Fanshawe College in London, Ontario. During her final year of studies she had the privilege of interning with the best in the business in Canada at The Weather Network. Once she finished her internship, she got the call from small-town Denison, Texas where she accepted a job as an on-air meteorologist at KTEN-TV, right in tornado alley, covering severe weather from Sherman/Denison (North Texas) to Ada (Southern Oklahoma). After the most active tornado season Oklahoma had seen in May 2019 (105 tornadoes!) Alana is excited to join WeatherNation to cover weather all across the nation. If you're interested in following her on social media she can be found @alanacameronwx!

<h3>WELCOME TO THE NORTH AMERICAN MONSOON SEASON. </h3>The North American Monsoon Season (NAMS) spans from June 15 through September 30th. It is also referred to as the Southwest Monsoon and is typically strongest during July and August. <h3>What is the North American Monsoon?</h3>The North American Monsoon is a seasonal change in atmospheric circulation that occurs during the summer across northwestern Mexico and the southwestern United States, including parts of Arizona, New Mexico, Nevada, Utah, Colorado, and California. The monsoon can bring stormy weather, flooding rains, dust storms, extreme heat, and wildfire concerns to the region.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 153448-1781473579558.png">As the land heats up during the summer months and high pressure develops over the Southwest, a shift in wind patterns pulls moisture northward from the eastern Pacific Ocean and the Gulf of California. This increase in moisture provides fuel for thunderstorms. As a result, the region can experience afternoon and evening thunderstorms, heavy rainfall over short periods of time, frequent lightning, gusty outflow winds, flash flooding (epecially in canyons and burn scar areas), and occasionally dust storms.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 152535-1781473586719.png"><h3>Seasonal Outlook</h3>For the upcoming season, the Climate Prediction Center's Seasonal Drought Outlook indicates that drought is likely to persist across portions of the Four Corners region, but improvement is expected in many areas. Meanwhile, drought conditions across Nevada are forecast to persist and may even expand.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 152751-1781473694048.png">Something to note, the CPC is not guaranteeing a wet monsoon season but they are favoring above-normal precipitation and improved odds of drought relief.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 152746-1781473762291.png"><h3>Why is it so important?</h3>The monsoon provides a large portion of the annual rainfall for many desert locations across the Southwest. In Arizona, for example, the monsoon can account for nearly half of the state's yearly precipitation. This rainfall can help reduce drought impacts, improve soil moisture, and lower wildfire risk. However, it can also bring hazards such as flash flooding and dangerous lightning.<h3><img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 155918-1781474388486.png">Forecast for this week</h3>Storms are in the forecast across parts of the southwestern United States, but heat will be the primary weather concern during the first few days of the monsoon season.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 160114-1781474494246.png"><img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 160128-1781474499827.png">For more on this season's monsoonal storm chances, be sure to join us on WeatherNation for the latest forecast and updates.

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.

El Niño has arrived! It didn't take long for La Niña conditions this spring to quickly be replaced in the equatorial Pacific over the last few months. A big surge of warm water has now reached the surface after traveling in deeper waters for months, taking sea surface temperatures up to the level needed for an El Niño designation.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2065059465326444738" src="https://x.com/NOAAComms/status/2065059465326444738"></div> El Niño is expected to continue for the foreseeable future (below), and will likely to continue to strengthen through the summer into fall and possibly winter (top of page). You've probably heard the term "super" El Niño mentioned - which is the same as a "very strong" El Niño in the graphic above. "Super" El Niño isn't a term officially recognized, but seeing temperatures that warm in the Pacific typically mean bigger impacts to global weather patterns, including hurricane season and the winter forecast in the United States. <img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-11 102033-1781194881870.png">A strong or very strong El Niño is different than a weak or moderate El Niño in terms of impacts. A very strong El Niño typically leads to a tighter and stronger sub-tropical jet, which increases wind shear in the Atlantic. If a moderate El Niño is in place through hurricane season, it's impacts in the Atlantic could be less pronounced. Regardless, WeatherNation will be monitoring the latest in the tropics and will bring you updates all season long.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-11 102059-1781195492270.png">To read the full release from NOAA about El Niño emerging - <a target="_blank" rel="noopener noreferrer nofollow" href="https://t.co/lS3v4K6TMC">click here!</a>

A cold front on Sunday brought severe weather from Ohio through the I-95 corridor, including weather delays and disruptions to the UFC Freedom 250 fight that took place at the White House. Here are some of the scenes from Saturday night's event (the night before) with lightning in the sky and rainbows in the distance.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2066226665722925506" src="https://x.com/WeatherNation/status/2066226665722925506"></div>Tornadoes were even reported from this system across portions of western Pennsylvania and eastern Ohio, as per the National Weather Service office in Pittsburgh.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 192919-1781487021404.png">Through the morning on Monday, storms appear to wind down, but the Storm Prediction Center has kept a SLIGHT (level 2 out of 5) risk for severe storms across the northeastern U.S. A risk of an isolated tornado or damaging winds remains as long as the front hasn't moved through your city.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 192850-1781487143198.png">The frontal boundary will clear the I-95 corridor and Atlantic Coast Monday morning.<video src="https://media.weathernationtv.com/app/uploads/2026/06/06-14 rne overnight-1781487189672.mp4" controls="true" width="100%"></video>Flood watches remain in place across portions of northern New England through Monday. Rivers, creeks, streams, and other low-lying areas are the biggest flood prone locations.<img src="https://media.weathernationtv.com/app/uploads/2026/06/Screenshot 2026-06-14 192933-1781487246840.png">The next roun of severe weather picks up by the second half of the work week for some of these areas, so enjoy the break from severe weather but stay tuned in for WEdnesday and Thursday's risk.
