The town of Sulphur, OK looks to have taken a direct hit from a destructive tornado on Saturday night. Unfortunately, more sights like this are starting to come to light throughout the day on Sunday. Our Field Correspondent, Brandon Clement, took this video earlier in the day:Related articles: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/tornadoes-touch-down-in-nebraska-and-iowa-on-friday">Destructive Tornadoes Tear Through Plains Friday</a> and <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/this-week-severe-weather-threat-continues">This Week: Severe Weather Threat Continues</a><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1784590897423765833" src="https://twitter.com/WeatherNation/status/1784590897423765833"></div>Unlike Friday, Saturday brought in more than double the amount of hail reports compared to tornado reports. The red dots below are all reports of tornadoes, not yet confirmed, but reports.<img src="https://media.weathernationtv.com/app/uploads/2024/04/lsr-1714302865222.png">The hail was large and damaging, along with the strong wind gusts and the confirmed tornadoes that touched down. About teacup-sized hail fell in Fox, OK on Saturday, and we're sure that hailstones that large will easily cause damage.<img src="https://media.weathernationtv.com/app/uploads/2024/04/Screenshot 2024-04-28 052810-1714303700198.png">This is a terrifying view of a tornado touching down in the rural area of Kendall, KS.

Our next system arrives from the Pacific Northwest and moves into the Great Plains by Tuesday and Wednesday. Once the associated frontal boundary taps into the moisture from the Gulf, we'll start to see the instability increase in the atmosphere.<video src="https://media.weathernationtv.com/app/uploads/2024/04/forecast-1714311741388.mp4" controls="true" width="100%"></video>The Storm Prediction Center (SPC) has issued a marginal and slight risk for Tuesday. The slight risk reaches through Spencer, IA, Omaha, NE, and down to Kansas City, MO. All forms of severe weather are on the table.<img src="https://media.weathernationtv.com/app/uploads/2024/04/spc-1714311927248.jpg">There's another risk for stronger storms on Wednesday, reaching from Topeka, KS, into Elk City, OK. Since these severe weather threats are still a few days out, this highlights the level of confidence the SPC has in the forecast.<img src="https://media.weathernationtv.com/app/uploads/2024/04/spc-1714312223064.jpg">The exact timing of this system is yet to be determined. As we get closer to the outlooks, that's one aspect of this forecast that will become more concrete. As of now, isolated storms have the potential to fire off around the peak heating hours of the day both Tuesday and Wednesday. The severe threat lingers into the overnight hours on both days, too.<video src="https://media.weathernationtv.com/app/uploads/2024/04/forecast-1714312370711.mp4" controls="true" width="100%"></video>Check back in with WeatherNation for more updates on this next system as we get closer to it.

If it seems like April has been particularly busy with severe weather, that would be correct - except for two days, each day this month has produced severe weather. Nearly half of those days have been Level 3 or higher. Please do not become a victim of severe weather fatigue and don't let your guard down.Related Articles: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/tornadoes-tear-through-the-heartland-friday">Tornadoes Tear Through the Heartland Friday</a> and <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/more-destructive-tornadoes-touch-down-in-oklahoma">More Destructive Tornadoes Touch Down in Oklahoma</a><h2>Sunday</h2>More severe weather is imminent on Sunday as the front slowly moves east into warmer, moist air in the central and southern Plains. The Storm Prediction Center has upgraded to an Enhanced risk (level 3 out of 5) across the Great Plains and Midwest. Wind, hail, and a few tornadoes will be possible Sunday. Severe weather will continue overnight Sunday into Monday, so please multiple ways to get alerts overnight. <video src="https://media.weathernationtv.com/app/uploads/2024/04/boomies-1714334153344.mp4" controls="true" width="100%"></video>For the third day in a row, tornadoes will be possible, especially in the areas highlighted in brown below. These tornadoes will most likely be short-lived and embedded in the line of storms rolling through later tonight.<img src="https://media.weathernationtv.com/app/uploads/2024/04/tor-1714313710024.jpg"><h2>Monday</h2>The start of our workweek also comes with a risk of strong storms and all forms of severe weather possible. This time it won't be so much into the Great Plains, but more towards the Western Gulf. It's a Marginal risk right now (level 1 out of 5). Morning storms could reach into Louisiana for the start of the workweek. Isolated cells don't look to fire off in Texas until the afternoon and evening hours. The risk of storms lingers into Louisiana throughout the rest of Monday.<video src="https://media.weathernationtv.com/app/uploads/2024/04/Monday severe future radar-1714324956893.mp4" controls="true" width="100%"></video><h2>Flood Threat</h2>In addition to the severe weather, there is an ongoing flood threat. Many places in the Central Plains have already seen over 7" of rain in the past few days. This means the ground is already highly saturated in some spots, making it more likely to flood. The bullseye for the heaviest rain will likely fall in places towards the Western Gulf through Tuesday.<img src="https://media.weathernationtv.com/app/uploads/2024/04/forecast accumulation-1714313899652.jpg">A marginal and slight risk of flooding has been highlighted through southern Missouri, Arkansas, eastern Oklahoma, eastern Texas, and western Louisiana. With multiple rounds of heavy rainfall, the ground will struggle to absorb additional rain that falls over the coming days. Numerous areas of flash flooding, water over the roads, and rapidly rising rivers and creeks are expected in this area due to the torrential downpours.<img src="https://media.weathernationtv.com/app/uploads/2024/04/sunday wpc day 1-1714325034651.png">We're already starting to see our next <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/midweek-severe-storm-risk">severe weather threat form towards the middle of the workweek.</a> Continue to stay weather-aware and keep up with WeatherNation for all things weather.

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.

Snow piled up in the Rocky Mountains this weekend, with over two feet of snow reported in parts of Colorado! Even the Denver metro area saw accumulating snow Saturday morning.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1784356854233178450" src="https://twitter.com/WeatherNation/status/1784356854233178450"></div> Many mountainous areas from the Cascades to the Rockies reported heavy snow from mid-week into the weekend, with the Front Range of Colorado reported the highest totals thus far.<img src="https://media.weathernationtv.com/app/uploads/2024/04/Screenshot 2024-04-28 062758-1714307296262.png">Moisture lingering behind the trough and afternoon heating will lead to a few more pop-up rain and snow showers on Sunday. Winter alerts are in effect for SE Wyoming's Snowy Range, where several inches of snow and gusty winds are expected.<video src="https://media.weathernationtv.com/app/uploads/2024/04/forecast-1714319083449.mp4" controls="true" width="100%"></video>Additional snowfall is only expected to top a few inches on Sunday but could create travel issues on mountain passes, including on I-70 and I-80.<img src="https://media.weathernationtv.com/app/uploads/2024/04/snow accumulation-1714319142786.jpg">Snow this late in the season is not unusual in the Colorado Rockies. In fact, even more snow is possible toward the end of the computing workweek. Denver has recorded measurable snow into late May - with mountain snow chances lingering even longer. This is great news for the handful of ski resorts that remain open, and hope to extend their season even further.

We've kicked out the chilly weather and are welcoming back in warm temperatures! High pressure along the East Coast will help bump up highs into the 70's and 80's this afternoon. Some locations like Toledo and Evansville could threaten record highs. <video src="https://media.weathernationtv.com/app/uploads/2024/04/2024-04-26 08-55-00-1714144926800.mp4" controls="true" width="100%"></video>Highs will tack on another few degrees to kick off the workweek tomorrow. That will put a few more of us in the record conversation on Monday.

<h2>North Side - Nebraska &amp; Iowa</h2>Several teams of meteorologists and storm damage experts are actively investigating and surveying damage from Friday across the I-80 corridor. The National Weather Service in Omaha has five survey teams actively surveying damaged areas.<img src="https://media.weathernationtv.com/app/uploads/2024/04/Screenshot 2024-04-27 091236-1714230904887.png">It all started when a tornado touched down in Lincoln, NE, just before 3 PM central time on Friday. This storm was tornado-warned for more than 50 miles as it tore through suburbs of the Omaha metro and eventually moved across the Missouri River and into Iowa.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1783955995875565622" src="https://twitter.com/WeatherNation/status/1783955995875565622"></div>This tornado struck Waverly, NE, a suburb on the NE side of Lincoln, where it derailed a train.

More people die from heat every year than ALL other extreme weather COMBINED. So how do you know how hot it is it really going to be?&nbsp;The National Oceanic and Atmospheric Administration [NOAA] and the Centers for Disease Prevention and Control [CDC] worked collaboratively to produce a new HeatRisk tool rolling out this summer from coast to coast. The tool had previously been used on the West Coast, but the 2024 summer will bring this experimental product to all cities across the U.S. According to Kimberly McMahon, the NWS Public Weather Services Program Manager, "HeatRisk is a great tool to just put into context, how hot it's going to be compared to what they're used to." The HeatRisk scale ranges from minor to extreme impacts and is color-coded from yellow to magenta. For reference, a MINOR impact day is your typical summer day.&nbsp;MODERATE days bring impact to vulnerable populations, especially people who are in the sun for long periods or without A/C. On these days, fans and open windows help to alleviate heat impacts inside.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2024/04/major-1713896597233.jpg">MAJOR impact days can be deadly for those without A/C and power interruptions are possible due to the heat stress. Hospitals are likely to see an increase in the number of ER visits due to heat-related illnesses. Outdoor activities should be shifted to cooler times of the day.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2024/04/mod-1713896597231.jpg">Finally, EXTREME impact days are for long-duration or potentially record-breaking heat events. There will be little to no relief from the heat overnight... and power outages are likely due to the stress on the grid. Outdoor activities should be canceled, and you should stay in cool spaces.&nbsp;&nbsp;In 2023 during Phoenix's month-long stretch of 100°+ degree days, more people died in their un-air conditions homes than outdoors. <img src="https://media.weathernationtv.com/app/uploads/2024/04/xtreme-1713896597235.jpg">The HeatRisk tool incorporated heat forecast and historical data from NOAA to include: how above normal the temperatures are, the time of year, the duration of the heat, and overnight relief potential.&nbsp;It also considers at what temperature heat deaths occur for over 700 cities in the U.S.. That data was imperative in designing the tool to know at what level heat becomes deadly, unique to geographic location. For example, Phoenix's 110°, though hot, wouldn't be an "extreme" day during the summer. Take that same 110° but for Chicago? The risk becomes extreme. Look for the new HeatRisk product and temperature forecasts this summer on WeatherNationTV.

Supported by NOAA's Regional Integrated Sciences and Assessments (RISA) and co-authored by <a href="https://cpo.noaa.gov/Meet-the-Divisions/Climate-and-Societal-Interactions/RISA/RISA-Teams/CNAP#739083-risa-teams">California-Nevada RISA</a> PI Alexander Gershunov, the study analyzed 40 years of data from the National Flood Insurance Program to quantify atmospheric rivers’ economic impacts.

<img class="alignnone size-full wp-image-70827" src="https://media.weathernationtv.com/app/uploads/2017/01/Atmospheric-River.jpg" alt="" width="3248" height="2229" />

 Not only were atmospheric rivers the primary driver across all 11 states, with annual average damages of $1.1 billion, but they also caused over 95% and even exceeded 99% of flood damages in some coastal areas of northern California and the Pacific Northwest. 

In addition, the authors used a recently developed atmospheric rivers intensity and duration scale varying from 1 (weak) to 5 (exceptional) to assess how flood damages change with each category. They found that each increase in the atmospheric intensity and duration scale corresponds to a roughly 10-fold increase in flood damages. Flood damages from atmospheric rivers are expected to increase in the face of rising population, increased development, and climate change.
