A strong area of low pressure rolls through the Rockies Saturday-Monday with a continuing chance of severe weather across the Plains.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-16 055402-1747396456543.jpg">As the strong low-pressure system approaches, southerly surface winds will increase ahead of it. As this occurs, the atmosphere will become increasingly unstable. A moist and unstable atmosphere will set up with dewpoints rising into the low to mid 70s°F, combining with strong daytime heating to create very strong instability. By Sunday afternoon, some of the highest instability levels of the season so far look possible.<h1><img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-16 055448-1747396501016.png">Outlook</h1>On Sunday, the Storm Prediction Center has issued an Enhanced Risk (Level 3 out of 5) has been issued for Kansas and northern Oklahoma, where the likelihood of severe storms is greatest. Severe thunderstorms capable of producing damaging winds, large hail, and tornadoes are expected in Oklahoma, Kansas, and northern Texas. As a mid-level shortwave trough moves over the region, storm development is likely, especially near a dryline in Kansas and Oklahoma. Strong deep-layer wind shear will favor the development of supercell thunderstorms, which have the potential to produce large hail and damaging winds. As the low-level jet strengthens throughout the day, tornadoes—including potentially strong ones—will become a significant threat. There is still a few days to go, so the fine details have yet to come into focus.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-17 112232-1747502662378.png">The highest confidence in storm development is over Kansas and northern Oklahoma, particularly near the triple point where the dryline and warm front intersect. However, areas farther south may still experience intense storms, even though storm coverage could be less certain. &nbsp;<video src="https://media.weathernationtv.com/app/uploads/2025/05/2024-07-26 07-30-17-1747502610611.mp4" controls="true" width="100%"></video>The severe weather threat continues into Monday, especially across Kansas, Oklahoma, and parts of the Midwest. A negatively tilted upper-level trough will help maintain a very moist and unstable environment east of a dryline, while a weakening surface low moves southward. Severe storms will likely develop along and east of I-35 in Oklahoma and southeast Kansas, with all severe threats like hail, wind, and tornadoes will be possible. The storm risk will decrease as you move farther north, but some elevated hail is still possible into northeast Kansas, southeast Nebraska, and Iowa.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-17 112442-1747502692772.png">Know where to go in case of a tornado or severe storm warning and review your emergency kits to ensure they include essential supplies like flashlights, batteries, a weather radio, and first aid items. Be aware of the difference between a watch (conditions are favorable for severe weather) and a warning (severe weather is imminent).&nbsp;Please continue to check the forecast and stay with us at WeatherNation as further details come in.

A progressive shortwave trough will be moving eastward across the Great Lakes region Saturday. As temperatures cool aloft and strong daytime heating continues, there will be enough energy to create favorable conditions for severe weather.Thunderstorms are already forming across New York and are expected to intensify as they move into a more unstable atmosphere by mid-afternoon. These storms have the potential to develop into supercells, with locally damaging winds being the primary threat. The strongest storms may also produce hail and possibly even a tornado or two. A severe thunderstorm watch has already been issued for the state of New York, Vermont, and New Hampshire.<img src="https://media.weathernationtv.com/app/uploads/2025/05/tomer east sat setup-1747444227140.jpg">The Storm Prediction Center has issued a Slight Risk for severe thunderstorms across the Northeast on Saturday. Strong wind, damaging hail, and tornadoes are possible. The severe weather risk is expected to peak in the afternoon as storm intensify and move into unstable conditions.<h1><img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-17 111206-1747501949742.png">Timing</h1>At the surface a warm front will move into the Northeast first with isolated showers and thunderstorms on Saturday. Watch for morning and midday rain/thunderstorms. Additional strong to severe thunderstorms might develop in the afternoon as the associated cold front moves into the region. These storms ahead of the cold front will be the strongest.<video src="https://media.weathernationtv.com/app/uploads/2025/05/2024-07-26 07-30-17-1747502492423.mp4" controls="true" width="100%"></video><h1>Rain Forecast</h1>Expect pockets of 1-2 inches of rainfall accumulation.<img src="https://media.weathernationtv.com/app/uploads/2025/05/tomer ne rain forecast-1747444607208.jpg">Stay with WeatherNation for the latest.

Texas and the Gulf Coast is really heating up with record daily highs likely through Sunday. In fact, we should set 13 record highs on Saturday.We set numerous daily record highs in Texas on Friday.<img src="https://media.weathernationtv.com/app/uploads/2025/05/tomer friday tx record highs-1747431088455.jpg"><img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-16 074732-1747403328649.png">Temperatures will remain well above average through the weekend across the South.<img src="https://media.weathernationtv.com/app/uploads/2025/05/tomer south record highs-1747431170341.jpg">Temperatures in San Antonio are likely to remain close to 100 degrees into Saturday into next week, with further records possible.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-17 112642-1747502835784.png">How do you stay safe in this kind of heat? It is early in the season, so many of us are seeing this type of heat for the first time this year. In light of this forecast, residents are encouraged to take heat precautions seriously. With many communities still in spring mode, it’s important to be proactive—especially in areas without widespread air conditioning or heat preparedness infrastructure.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 074710-1747144046862.png">Tune into the local regional forecast on WeatherNation for more details.

A large tornado tore through the city of St. Louis earlier on Friday, with widespread damage being reported. Unfortunately, there have been reports of fatalities.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1923513800935997721" src="https://twitter.com/WeatherNation/status/1923513800935997721"></div>As the supercell moved in from the west, low-level rotation tightened considerably, and a Tornado Warning was issued. The tornadic circulation moved from west to north of downtown and crossed over into Illinois before weakening.<video src="https://media.weathernationtv.com/app/uploads/2025/05/stlouistornado-1747439374288.mp4" controls="true" width="100%"></video>The National Weather Service in St. Louis will go out on Saturday and survey the tornado damage:<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1923549124852363401" src="https://x.com/NWSStLouis/status/1923549124852363401"></div>The St. Louis metro is no longer under a threat of severe thunderstorms for the rest of the evening.

MID-ATLANTIC - A slow-moving upper-level low contributed to several flash flood emergencies across areas of Virginia and Maryland earlier this week. The same system is contributing to a storm and rain threat that will persist into the weekend.<img src="https://media.weathernationtv.com/app/uploads/2025/05/1-1747337632590.png">On Friday and Saturday, a cold front will be swinging out of the Midwest. As a result, there is a higher chance of severe storms along the East Coast. By Friday night, we will be keeping a close eye on some weakening severe storms coming out of the Ohio Valley. Saturday, daytime heating will likely spark new severe storms along the cold front.<video src="https://media.weathernationtv.com/app/uploads/2025/05/ecfri-1747353561140.mp4" controls="true" width="100%"></video><img src="https://media.weathernationtv.com/app/uploads/2025/05/1-1747338314421.png">Tune into WeatherNation :10 past the hour for the eastern regional forecast for more updates.

ARIZONA - While the Bryce Fire has been burning for over a week now a new fire has scorched just as many acres in Arizona. A new fire, the Greer Fire, has torched over 7,000+ acres with little to no containment.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-14 163118-1747261893542.png">According to the Arizona Department of Forestry and Fire Management, the fire continues to burn in the region.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1922767831491579904" src="https://x.com/azstateforestry/status/1922767831491579904"></div>The fire weather concerns are continuing, with winds fanning any spark or a flame into a potential wildfire. Those winds reached 60 mph on Tuesday, pushing the Greer Fire through the wooded areas of Apache County. Winds today will likely reach the same numbers in the afternoon.<video src="https://media.weathernationtv.com/app/uploads/2025/05/05-14 thu-1747271844737.mp4" controls="true" width="100%"></video>Ever wonder what to do if you're caught in a dust storm? Pull off of the road COMPLETELY and turn off your lights as soon as possible, to prevent other cars from running into the back of you.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-14 105044-1747241454397.png">The wildfire threat will back off a bit Thursday afternoon but won't disappear. An elevated risk for fire weather will carry us into Thursday.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-14 191807-1747271897874.png">
