Yep, you read that right — a nor’easter is setting its sights on the Northeast. If you’re from the region, you know what that means: high winds, big waves, and usually heavy snow. This time, we’re skipping the snow — but a cold, soaking rain is likely.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-21 070458-1747833243953.png"><h1>SETUP</h1>A slow-moving low will be overtaken by a secondary ripple of energy late tonight into Thursday. That secondary disturbance will ignite the development of our nor’easter. As the system deepens, winds will ramp up, drawing in cooler air and fueling the storm even further.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-21 070447-1747833226004.png"><h1>WINDS</h1>Regardless of time of the time of year, you can't have a nor'easter without some winds. Gusts of 40–50 mph are expected across eastern Massachusetts through Thursday. Secure loose objects and be prepared for possible tree damage.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-21 070537-1747833381138.png"><h1>RAIN</h1>While it won’t be cold enough for snow this time, we’re looking at a driving rain — possibly coming in sideways! A couple of inches are likely across much of the region, with the heaviest totals (up to 4 inches) expected from Pennsylvania through southern New England.<h1><img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-21 190800-1747876135935.png">POWER OUTAGES</h1>Saturated soils plus strong winds? That’s a recipe for scattered power outages. If you plan to use a generator, remember to run it at least 20 feet away from your home for safety.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-21 071756-1747833546570.png">

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.

RED RIVER VALLEY - After a very active start to the week, severe chances are back in the forecast for the Red River Valley, the Arklatex, and central Texas. The Storm Prediction Center has issued a SLIGHT (level 2 out of 5) risk for severe storms on Thursday across these areas. This risk includes cities such as Dallas, Texas.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-21 191208-1747876512374.png">Conditions will be favorable for intense storms, with warm, humid air (upper 60s to low 70s dewpoints) and strong winds at different levels of the atmosphere. This setup could lead to supercell thunderstorms, which are capable of producing large to very large hail as well as a chance for a tornado.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-21 191746-1747876673945.png">Strong storms are likely to form in central Oklahoma on Thursday, starting north of the Red River. These storms will move south into northern Texas during the day. <video src="https://media.weathernationtv.com/app/uploads/2025/05/05-21 rsc-1747876711988.mp4" controls="true" width="100%"></video><h2>Friday - Saturday</h2>On Friday, moist air returns ahead of our next system that is expected to form over the High Plains. This will lead to thunderstorms in the central nd southern Plains, some of which could turn strong to severe. The SPC has issued a MARGINAL (level 1 out of 5) risk for severe storms on Friday for Nebraska, Kansas, Oklahoma, Missouri, Arkansas, and into western Texas. West Texas's storms will be driven by a dryline.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-21 191915-1747876928035.png">Strong storms, including supercells with hail, may form in the afternoon and evening, especially in Colorado and surrounding areas.<video src="https://media.weathernationtv.com/app/uploads/2025/05/05-21 fri to sat-1747876970216.mp4" controls="true" width="100%"></video> There is a flooding risk with this weekend's storms as well. The WPC has issued SLIGHT (level 2 out of 5) risks for flash flooding across the Plains for Saturday and Sunday. On Saturday, flash flooding is possible in the Ozarks and north-central High Plains. On Sunday, a larger area from northeast Texas to the Mississippi Valley is at risk for heavy rain and flooding. More storms could develop in the southern Plains and Lower Mississippi Valley.<img src="https://media.weathernationtv.com/app/uploads/2025/05/ezgif-22b4500ecfe168-1747877171068.gif">For the latest on this story, be sure to join us on WeatherNation!

The stretch of record heat continues in Texas, Louisiana, and Florida through Saturday. Highs stay in the 90s and low 100s.<h2>Texas</h2>Southern Texas has been scorching hot with days of records over the past few days. Through the end of the week, there are still many locations including Austin, that could break record highs.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 210028-1747796535880.png">Forecast highs in Austin and Houston on Thursday will rise to the mid-90s.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 210020-1747796549104.png"><h2>Florida</h2>Records are likely to fall in Florida at the end of the week as well.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 210024-1747796636064.png">Temperatures on Thursday are expected to be in the 90s across South Florida, with heat index values even higher.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 210034-1747796659553.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.

Hurricane Season has begun in the Eastern Pacific basin, right on schedule. The season officially kicked off on May 15, and just days in, we have our first area to monitor.An area off the western coast of Mexico (pictured above), an area of low pressure, could form this weekend or early next week. This development would be hundreds of miles south of Mexico. Conditions appear favorable for a tropical depression to form around mid-next week.That said, take any long-range model output with a grain of salt. The Eastern Pacific hurricane season typically ramps up slowly, with activity peaking in mid-August and again in late September.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 073348-1747748094171.png">If this system were to strengthen and receive a name from the National Hurricane Center, Alvin would be first on the list in the Pacific.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 070214-1747748273874.png">

Severe Storms Move East Overnight

Pea size, baseball size, even grapefruit size?

There are many everyday items that we can use to determine the best estimate of a hail stone.

<img class="alignnone wp-image-90381 size-full" src="https://media.weathernationtv.com/app/uploads/2018/04/hail-size-chart-pics.jpg" alt="" width="630" height="617" />

Pea size hail is ¼" in diameter and hail at ¾" is the width of a penny.

When hail is 1" in diameter, that’s the same size as a quarter and also when hail size is considered "severe" (or large enough to potentially cause damage).

<img class="alignnone size-large wp-image-90382" src="https://media.weathernationtv.com/app/uploads/2018/04/quart-728x408.jpg" alt="" width="728" height="408" />

Some of the most destructive hail that falls measures at least 2" in diameter!

Tennis ball size is 2 ½", baseball size measures 2.75", tea cup size is 3", and softball size measures 4" in diameter.

<img class="alignnone size-large wp-image-90383" src="https://media.weathernationtv.com/app/uploads/2018/04/weldon-1-728x408.jpg" alt="" width="728" height="408" />

Did you know hail can be even larger than that?

https://twitter.com/i/status/1258580136699420674

The biggest hailstone ever recorded was near Vivian, South Dakota in 2010, coming in at 8” in diameter!

Just remember -- before you go outside to measure the size of hail that fell in your backyard, wait until the storm has moved far enough away so you can safely make your observation.
