A widespread severe weather outbreak is expected to unfold across parts of the central United States over the next several days, bringing the threat of tornadoes, damaging winds, large hail, and flooding rain from the Plains into the Midwest. Forecasters warn the most dangerous conditions are likely to develop Sunday and Monday as a powerful storm system moves across the region.&nbsp;Another strong upper-level trough will be dropping across the Great Plains on Sunday and Monday. Model data continues to hint at stronger ingredients coming together, including instability and wind shear. Sunday, moderate to high instability will be building in. Southwesterly winds aloft and southerly winds at the surface will enhance wind shear, and changing wind direction with height would increase the tornado threat.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 070401-1778936653288.png"><h1>Severe Outlooks</h1>Sunday, atmospheric conditions are expected to become even more favorable for dangerous storms to develop across parts of the northern and central Plains. SPC has highlighted an Enhanced Risk for Sunday and Monday across the Central Plains as all modes of severe weather will be possible, including strong tornadoes, very large hail, and destructive damaging winds, especially in areas stretching from Nebraska into South Dakota, Minnesota, and Iowa. In addition to the tornado threat, widespread damaging winds and large hail could impact several communities.<img src="https://media.weathernationtv.com/app/uploads/2026/05/1-1778958431970.png"><img src="https://media.weathernationtv.com/app/uploads/2026/05/1-1778958495432.png"><img src="https://media.weathernationtv.com/app/uploads/2026/05/1-1778958521402.png">The severe weather risk is expected to peak on Monday as the storm system pushes farther east. A large portion of the central U.S. could face dangerous thunderstorms, including areas from Texas and Oklahoma northward into Iowa and Wisconsin. Major cities such as Dallas, Oklahoma City, Kansas City, Omaha, Chicago, and Minneapolis could experience strong to severe storms. Some storms may become capable of producing long-track tornadoes and widespread wind damage.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 070854-1778936948017.png"><h1>Forecast</h1>On Sunday, storms will still linger along a warm front across Nebraska and Iowa. By the afternoon and early evening hours, supercells are expected to develop near the cold front, which could lead to all severe weather hazards. Into the overnight hours, storms will congeal into a complex that will promote damaging winds. Monday will be similar to Sunday with all hazards, but damaging winds will overwhelmingly become the biggest hazard into the evening and overnight hours.<video src="https://media.weathernationtv.com/app/uploads/2026/05/FORECAST-1778943456995.mp4" controls="true" width="100%"></video>Heavy rainfall will also be a growing concern throughout the event. Repeated rounds of thunderstorms may lead to flash flooding in low-lying and flood-prone areas, especially where storms track over the same locations. Rainfall totals could add up quickly across parts of the Plains and Midwest before the system finally shifts eastward by the middle of next week.<img src="https://media.weathernationtv.com/app/uploads/2026/05/1-1778958627657.png">Tune into WeatherNation for more details.

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.

Scattered severe storms have been moving through portions of the Great Plains and Midwest this week, including on Friday around portions of Nebraska, Iowa, and Wisconsin. The same low pressure system will hardly move on Saturday, prompting another round of severe storms. <img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 051332-1778930356757.png">Near record-breaking heat has helped to increase instability in the atmosphere. The warm sector (south of the warm/red frontal boundary) will be favored for isolated to scattered severe storms. Areas closer to the low-pressure system could see a few tornadoes as the rotational energy is higher.<h1>Outlook</h1>There is an Enhanced risk (level 3 out of 5) across the western corners of Nebraska and Kansas. Additionally, a Slight risk (level 2 out of 5) includes the surrounding areas from Colorado through central Iowa.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 081402-1778940862334.png">Extra large hailstones (over golf ball size - 2"+) and hurricane force gusts (74+ mph) are possible for areas below, which should be the more widespread hazards.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 081431-1778940884977.png">Several tornadoes are possible as well, primarily in western Kansas and Nebraska.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 081453-1778940905064.png"><h1>Forecast</h1>Storms have persisted along the warm front overnight from Illinois through Michigan and Indiana. Areas along the front between the Great Lakes and the Ohio River have a better chance of seeing storms early in the day before they become more widespread in the afternoon. Storms in the Plains and Midwest could persist well into the overnight hours, so please have multiple ways to get severe weather alerts that can wake you up!<video src="https://media.weathernationtv.com/app/uploads/2026/05/2026-05-16 08-15-39-1778940992326.mp4" controls="true" width="100%"></video>Since storms won't be widespread, only spotty heavy rain is expected. Isolated flash flooding is possible.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 081516-1778940925426.png">

Welcome to May in Colorado. This weekend forecast will be wacky with severe storm chances Saturday and Sunday. On the colder side of the event into Monday, snow is looking likely for the Rockies.<img src="https://media.weathernationtv.com/app/uploads/2026/05/1-1778873046914.png"><h1>Severe Storm Forecast</h1>Saturday, an Enhanced Risk has been issued for parts of Northeastern Colorado, Northwestern Kansas, and Southwestern Nebraska. The biggest hazards will be destructive hail and strong winds. The same areas will be at play for severe on Sunday including Denver Metro.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 062004-1778934023591.png"><img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 062011-1778934038231.png">Scattered thunderstorms will pop Saturday afternoon across Colorado and Wyoming and get stronger as they move eastward into the Plains. A few isolated tornadoes can't be ruled out either. Sunday, a new surface low forms along a passing cold front. It will force more widespread showers and storms during the day. As the upper low drops surface temperatures, snow will begin to mix with the rain in the high country and snow will gradually drop with elevation too. It can't be completely ruled out with some flakes in the Denver Metro.<video src="https://media.weathernationtv.com/app/uploads/2026/05/2026-05-16 06-21-09-1778934115879.mp4" controls="true" width="100%"></video><img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 062048-1778934056767.png">

A big warmup is expected to take hold across the eastern United States in the coming days, bringing temperatures that will feel more like midsummer than mid-May. Much of the East Coast, Mid-Atlantic, and Northeast could see temperatures surge well above average as a strong area of high pressure settles over the region.&nbsp;RELATED: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/severe-storms-possible-in-the-plains-midwest-to-end-the-week">Severe Chances on the Plains</a>A strong ridge of high pressure is migrating eastward over the next few days. That brings it squarely over the southern and central plains by the end of the week.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-15 171204-1778886738109.png">Highs look to be the worst in the Southern Plains in terms of raw temperatures, closing in on the century mark. Record highs will be likely into early next week.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 081153-1778940724828.png">After a stretch of cooler spring weather, warmer air is expected to spread eastward through the weekend and into next week. High temperatures are forecast to climb into the 80s across many areas, while some cities could approach or even reach 90 degrees for the first time this year. <img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-03-29 061131-1778851192032.png">Major cities along the Interstate 95 corridor, including Washington, D.C., Philadelphia, and New York City, may come close to daily temperature records if the heat intensifies enough. Some locations could end up 20 to 30 degrees warmer than what is typical for this time of year.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 081241-1778940784602.png">The heat is also expected to stick around for several days instead of quickly moving out, making it one of the more significant warm spells so far this spring. Increasing humidity levels may enhance the summer-like feel, especially in the afternoons and evenings.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-16 081249-1778940795899.png">The unusually warm pattern is expected to continue into next week before cooler air eventually returns. While many people may enjoy the warmer weather, the sudden jump in temperatures could lead to increased energy use and may be difficult for those who are sensitive to heat.&nbsp;For more tips on how to beat the heat tune into WeatherNation.

Ready for hurricane season? As a reminder, waters in the tropical Pacific tend to warm faster than in the Atlantic; thus, the season starts about two weeks earlier in the Eastern Pacific. The CPC has moderate confidence in the formation of a tropical system in the Eastern Pacific going through the end of May into June. If you have travel plans along the SW coast of Mexico, stay up to date with the forecast.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-13 054445-1778672697750.png"> If a storm were to form and reach tropical storm status, it would be named Amanda.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-02 080308-1777731407202.png">Ocean heat content has been rapidly increasing in the Eastern Pacific this Spring, which is not surprising. You might've heard about the potential for a "super" El Niño this summer. Well, the warm water created in the Eastern/Central Pacific by El Niño can lead to supercharged hurricane seasons in those regions.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-15 050125-1778842896285.png">Global circulations influenced by El Niño tend to create less disruptive wind shear in the Eastern Pacific as well. Weak upper-level winds combined with warm waters tend to lead to the development of many tropical systems. At the same time, wind shear tends to increase in the Caribbean during these events, making it tougher for tropical systems to form and survive.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-02 080343-1777731377186.png">Last season was quite active in the Eastern Pacific, with 20 named storms and 5 major hurricanes. The Mexican National Meteorological Service issued an early outlook for the 2026 season in April, calling for another active year with roughly 20 named storms.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-02 081157-1777731386253.png">El Niño typically increases wind shear in the Atlantic, which is a primary reason why some forecasts are calling for a slightly less active season. The Atlantic averages 14 named storms a season. Despite the El Niño, the forecast is just slightly below average with 13 named storms.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-08 065820-1778245110818.png">We're going to get you ready for hurricane season at the beginning of June. Be sure to tune in for updated forecasts, information, and tips to prepare.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-02 083105-1777732279156.png">

<h1>WHAT TO EXPECT</h1>The SPC has issued a slight risk across the Northwest and portions of Utah. Unusually warm temperatures, combined with a frontal boundary, will help enhance winds in the area by this afternoon. Winds could gust in excess of 75 mph in some locations that get caught underneath a strong storm. <img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-13 115353-1778694842992.png">The low and its associated frontal boundary are moving onshore, bringing rain and storms along with it. As highs soar into the 90's, storms will strengthen with the potential of damaging winds and hail. By Thursday morning, the frontal boundary will move out.<video src="https://media.weathernationtv.com/app/uploads/2026/05/wed agerrr-1778638388237.mp4" controls="true" width="100%"></video>Rain is not much of a concern with this system. In fact, the lack of rain actually is a concern - some of these thunderstorms could be completely dry, meaning we get the harm of lightning and the winds without the help of rainfall.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-13 115430-1778694882207.png">It will be windy regardless; High Wind Warnings cover areas that could see 65 mph winds, and areas that have a wind advisory could see gusts approaching 45-50 mph.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-13 115508-1778694919840.png">

Phoenix, Arizona is known for its blazing 100°+ heat during the summer. But early May is a bit, well, early for the kind of heat that the Valley of the Sun saw on Sunday.

Phoenix set a record high on Sunday, with temperatures soaring into the mid-100s. Through 1pm Phoenix time on Sunday afternoon, Sky Harbor Airport had warmed to 106°, breaking the old daily record of 105° from 1947. It's also the warmest reading so far in 2018 for Arizona's capital city.

Sunday's 100°+ reading marks the fourth triple-digit temperature so far in 2018 for Phoenix, a remarkable feat for a city that averages its first 100° day on May 12th.

And of course, the heat isn't going away anytime soon. The week ahead promises more near-record level high temperatures and it's probably also worth noting that Phoenix averages 110 days of 100°+ high temperatures per year. Hopefully you're near a <a href="https://www.phoenix.gov/parks/pools">Phoenix-area pool</a>!

A big ridge of high pressure is steering , and allowing the sun to bake Arizona and much of the Four Corners states, along with California and Nevada, with well above-average temperatures for this time of year.<img class="alignleft size-full wp-image-91069" src="https://media.weathernationtv.com/app/uploads/2018/05/west-pattern.jpg" alt="" width="1920" height="1080" />
