A slow-moving frontal boundary that brought numerous days of severe weather to the Plains, has hit a snag down south. It's in the process of stalling out, which will provide the focus for storm chances over the next few days. With multiple rounds of storms on the way, flooding is a growing concern. Some areas of Texas have already seen 3-4 inches of rain!<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-20 043144-1779273210458.png"><h1>FORECAST</h1>Going forward, the heaviest of the rainfall will target the lower Mississippi River Valley, into the Midwest. Some areas will pick up 3-5 more inches with some localized areas surpassing that easily. If you live in a flood-prone area of the southern plains into the Ohio River Valley, be prepared to seek higher ground. <img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-20 043534-1779273342489.png">With rounds of heavy rain expected over the next several days, the Weather Prediction Center (WPC) has issued 5 straight Excessive Rainfall Outlooks highlighting the flash flood threat. <img src="https://media.weathernationtv.com/app/uploads/2026/05/2026-05-2004-38-04-ezgif.com-video-to-gif-converter-1779273605586.gif">A good reminder to avoid driving through flooded roadways at all costs. You never know what's under that water.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-19 053417-1779190502548.png">

A big warmup is taking hold across the eastern United States, bringing temperatures that will feel more like midsummer than mid-May. Much of the East Coast, Mid-Atlantic, and Northeast saw temperatures surge into record-breaking territory as a strong area of high pressure settled over the region.&nbsp;Numerous records were broken on Tuesday afternoon, including Newark, NJ, which hit a high of 99 degrees. The NE can see one more day of record warmth before temperatures cool off.<img src="https://media.weathernationtv.com/app/uploads/2026/05/NORTHEAST HIGHS-1779242730674.png">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>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 in the Northeast. The normal average for New York City this time of year is 72°, but the forecast high is expected to be 85° on Wednesday. Temperatures will dip back down to the 60s on Thursday, once a front passes.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-20 030656-1779268041186.png">On Wednesday, more records will be broken with some locations up to 20 to 30 degrees warmer than what is typical for this time of year.&nbsp;This has prompted heat advisories through Wednesday afternoon. Major cities along the Interstate 95 corridor, including Philadelphia and New York City, will come close to daily temperature records if the heat intensifies enough. <img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-20 031314-1779268412172.png">Additional records are likely to fall through mid-week across the East before our central U.S. cold front draws in cooler air and stormy weather.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-20 032043-1779268878961.png">Despite the urge, stay out of the waters in the area.

By the end of the week, many spots will be closer to seasonal norms in the 70's<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-20 031551-1779268564533.png">

The most likely threat will be damaging winds on the leading edge of the front. There is a marginal risk for severe weather (in the green) from the Northeast to Texas, where isolated severe storms are likely.<h1><img src="https://media.weathernationtv.com/app/uploads/2026/05/OVERNIGHSSSS DDDD-1779243272306.png">Wednesday</h1>This front is in no hurry to get out of here. It'll stall out across the Northeast and extend through the Lone Star State. This will give us two separate spots to watch for severe weather. The main threat for both spots will be hail and damaging winds. However, the potential for large hail in Texas is not out of the question.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-19 143749-1779223127143.png"><h1>Forecast Timing</h1>The front will likely spark up storms into the overnight hours along the boundary.

SIMI VALLEY, CA - On Monday, May 18th in Ventura County California, a new wildfire formed named the Sandy Fire. It has since burned over 1600 acres and grew quickly threatening life and property. This prompted evacuation orders and warnings to the area.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-19 201844-1779243549513.png">Footage in the region shows the extent of the smoke and poor air quality.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2056736634754809931" src="https://x.com/WeatherNation/status/2056736634754809931"></div>Additional fires have since quickly formed in southern California, despite no red flag warnings or fire weather outlook. The winds managed to be strong enough for fires to quickly get out of control in the areas. The Bain Fire in Riverside started to burn heavy fuels at a moderate rate before quickly burning up to almost 1000 acres. This prompted evacuation orders and warnings for many Riverside Zones.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-19 201848-1779243680495.png">Due to the extent of several wildfires burning in southern California, poor air quality has increased in the area and air quality alerts have been issued for the Great Los Angeles area.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-19 201852-1779243714991.png">For more on these, be sure to join us at WeatherNation at :50 past the hour.

<h1>SUNDAY</h1>A potent setup, fueled by record hot temperatures, lead to destructive severe storms this past weekend. The worst of the days was easily Sunday, with over 300 reports of severe weather, including hail, damaging winds, and a few tornadoes.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-18 110814-1779124204412.png">A strong tornado touched down in Nebraska as a part of the outbreak.

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!

Numerous fires have been burning from the panhandle to the western Plains. Through Tuesday morning, there is an extreme fire danger across these areas. This is the highest level of outlook that the Storm Prediction Center issues. The extreme risk is not often issued, and typically denotes conditions that could lead to the unstoppable spread of fires. Residents in these areas should review their evacuation plans and have a "go bag" ready with essential items like medications and important documents. Don't forget your pets!Our field correspondent, Jonathan Petramala has been following these fires, and here's his latest report.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2056487491100975119" src="https://x.com/WeatherNation/status/2056487491100975119"></div>The fire danger weans as we head into Tuesday but remains at elevated levels for portions of Arizona and New Mexico.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-18 162935-1779143455125.png">Make sure you're prepared for fire danger and know all the ways to prevent a fire too.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-18 085121-1779115885540.png">

Minor additional accumulations will fall in Michigan, but up to 6" of new snow may fall from near Lake Erie through the Appalachians to Cape Cod. An upper level disturbance moving through the Great Lakes and a low pressure center in the Atlantic Ocean will bring the snowfall. The moisture will move out of the region and diminish Tuesday afternoon.
