The trough responsible for the storms along the East Coast on Sunday will be followed by another similar system. The threat of strong winds returning will have Halloween decorations shaking again as this system moves into the Midwest.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1979751863043113082" src="https://x.com/WeatherNation/status/1979751863043113082"></div>The one main difference: this front doesn't look like it has enough moisture to fire up a lot of storms. But there will be rain...<h1>WIND</h1>We're going in order of impact, with this system being the wind maker that will have any foliage howling. Gusts could top 40 mph in areas of the Upper Midwest on Monday, with 20-30 mph gusts around the Great Lakes on Tuesday and Wednesday. In case you didn't learn your lesson with this trough's predecessor, secure the Halloween decorations. It won't clean out all of the foliage in these areas, but the days of enjoying the leaves are starting to get limited.<video src="https://media.weathernationtv.com/app/uploads/2025/10/10-19 midwest windy-1760927134113.mp4" controls="true" width="100%"></video>Wind alerts, including high wind alerts, have been issued for the High Plains on Monday for winds of 40 mph and gusts upwards of 60 mph.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-19 202856-1760927344079.png"><h1>TEMPS</h1>Aside from the wind (and projectile leaves), the refreshing cooldown will get you in the Fall mood if your neighbor's inflatable pumpkin doesn't. Temperatures in some places, like Minneapolis, will go from nearing 60 to struggling to get out of the 40s.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-19 072622-1760880641583.png"><h1>RAIN</h1>Who's ready for the lake effect machine? Well, it's starting this week...sorta. Lake-enhanced showers will make an appearance with this system on Tuesday and Wednesday, but it's the same principle. Cold air moving over a relatively warmer body of water and VOILA! It's just not cold enough for snow. We'll get there, especially if the lakes struggle to freeze over again like they did last Winter.<video src="https://media.weathernationtv.com/app/uploads/2025/10/10-19 rnc rne-1760927522277.mp4" controls="true" width="100%"></video><h3>Wanna see how your Winter is shaping up? <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/noaa-releases-outlook-for-winter-25-26">NOAA's Winter Outlook</a></h3>

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.

October has been relatively quiet in terms of severe weather. That all came to an end Saturday as storms rumbled through the Central and Southern Plains. A few storms actually produced severe weather reports, some of which were classified as tornadoes.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-19 155805-1760911139185.png">The National Weather Service in Little Rock, Arkansas, confirmed an EF-1 tornado was found in Hot Spring County from Saturday's storms.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-19 155304-1760911134206.png"><h1>Forecast Timing</h1>Now, the front is aiming for the northeastern U.S. One thing we've noticed is the lack of lightning with these thunderstorms, but the winds have been howling along the front. Through Monday morning, the severe weather threat continues into New England, for cities such as Boston, MA.<video src="https://media.weathernationtv.com/app/uploads/2025/10/10-19_rne bams3k overnight-1760926909056.mp4" controls="true" width="100%"></video><h1>Severe Outlook</h1>As the front moves eastward, a marginal risk (level 1 out of 4) remains in place east of the Appalachian Mountains and towards the Atlantic Coast.

Strong Fall Front Fires Up Severe Chances Through Monday Morning

As the Atlantic hurricane season enters its final stretch,&nbsp;a new tropical wave is emerging in the central Atlantic Ocean. The disturbance, which is moving westward at around 15 to 20 mph, has drawn attention from the National Hurricane Center (NHC) due to its potential to organize over the next several days. Although the system currently has a 70% chance of development in the short term,&nbsp;environmental conditions could become more favorable later this week as it approaches the Caribbean.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-19 200937-1760926311858.png">The long-range models have been hinting at some potential tropical development of the Caribbean wave this week.&nbsp;Right now, the wave is battling some dry air and moderate wind shear, two factors that often limit tropical development. By mid- to late week, as it continues westward, the system will encounter more humid air and slightly weaker upper-level winds. That is when long-range models&nbsp;indicate there is a better chance for gradual organization. Below is just ONE MODEL RUN of what could happen going forward!<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-19 200946-1760926334620.png"><video src="https://media.weathernationtv.com/app/uploads/2025/10/10-19_carib-1760926455289.mp4" controls="true" width="100%"></video>Sea surface temperatures remain warm across much of the Atlantic basin, providing ample fuel if the wave can find a pocket of lower shear and increased moisture. As this wave closes in on the Leeward Islands, little to no development is expected. However, heavy rain and breezy conditions will move through the island chain. What happens after that? Only time will tell.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-17 044010-1760697624879.png">The concerns? The Caribbean is still as warm as bathwater right now, so it wouldn't take much time for something to potentially organize. The concern after that? Where does the system go IF it develops? Again, still a big IF, but climatologically speaking, this is where we would expect an October storm. This latest tropical wave is part of a broader late-season pattern typical of October, when the main area of development shifts westward toward the Caribbean and Gulf. During this time of year, even a small system can strengthen quickly if the conditions align, making close monitoring essential for the islands and nearby coastal regions. While many tropical waves fade harmlessly over open water, the warmth of the western Atlantic and the seasonal transition can sometimes give these systems a late-season boost.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-16 075337-1760622828329.png">So what's the final outcome with this system? How many systems have "looked good" 7 days out and have fizzled on us this year? Are there some ensemble models that find some development? Sure. Are all of them developing this wave? Not yet. October is not the month to let your guard down.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-15 103336-1760546429287.png">Tune into WeatherNation for the top weather headlines for more on the tropics.

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.

Ready for another La Niña winter? NOAA quietly released it's outlook for the upcoming winter season on Thursday, sans press conference since the government shutdown continues. The press conference has been rescheduled to November but the outlook is still ready for us to digest. As a reminder, these outlooks are for the overall three month pattern and do not serve to predict seasonal snowfall totals or bursts of cold/warmth that are likely to impact areas highlighted with the seemingly opposite outlook. The National Weather Service released the following video showcasing the newly released outlooks for temperature, precipitation, and drought from December through February.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1978839667907744157" src="https://x.com/NWS/status/1978839667907744157"></div><h1>Temperature</h1>Above average temperatures are favored across the southern tier of the United States, while below average temperatures are favored across the Upper-Midwest and Northwest. <img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-17 065848-1760706897085.png"><h1>Precipitation</h1> As the jetstream is likely to remain more active across the northern tier of the country, allowing for cooler air, it should also allow for more storms to track through these areas. As such, above average precipitation is favored from the Northwest through the Great Lakes, while drier than average conditions are expected from Southern California through Florida and the Carolinas. <img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-17 065852-1760706026499.png"><h1>Influences</h1>In case you missed it, <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/la-nina-advisory-issued-how-this-could-affect-the-winter-season">a La Niña Advisory was issued last week</a> as these conditions were observed in the equatorial Pacific west of South America. La Niña is expected to persist through winter, which is one of the primary reasons the winter outlook favors the areas it does. La Niña patterns vary greatly from year to year, depending on the strength of La Niña and the phase of the PDO (Pacific Decadal Oscillation). The graphic below shows the typical pattern of the Pacific and Polar jets during a La Niña winter, which usher in cooler and wet air masses. <img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-17 065856-1760707324994.png">There is lower confidence that La Niña continues through the late winter and early spring (graphic below), which could throw a wrench in the seasonal forecast. <img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-17 073303-1760707994646.png">ENSO (El Niño &amp; southern Osciallation) neutral conditions have a less obvious pattern influence, but wetter conditions can develop farther south than during La Niña.

A ridge of high pressure has been responsible for the quiet and warm days across the central U.S., but on the western periphery of this ridge, a trough will attempt to slide in and ignite severe weather chances across the High Plains. The storms that are steered between these two upper-level systems are what we often refer to as "ridge-riding" thunderstorms.<video src="https://media.weathernationtv.com/app/uploads/2025/10/2025-10-16 05-09-22-1760612987566.mp4" controls="true" width="100%"></video>On Thursday, another MARGINAL (level 1 out of 5) risk is issued as the cold front shifts down into eastern Colorado and western Kansas, even extending all the way into central Nebraska. All kinds of severe weather are possible.<img src="https://media.weathernationtv.com/app/uploads/2025/10/1-1760669659768.png">There is a small risk of tornadoes in the latest SPC advisory for Thursday. It covers cities from North Platte, NE, over to Colby, KS and as far south as Cheyenne Wells, CO. Make sure you have a way of getting notified if anything is to touch down.<img src="https://media.weathernationtv.com/app/uploads/2025/10/1-1760640961225.png">The cold front keeps pushing east into Missouri and Oklahoma for Friday. Similar to Thursday, severe potential will exist during the heating of the day but some storms could remain strong even after sunset!

Sierra to the Rockies: Flooding Rain & Heavy Snow

[<a href="https://blog.nssl.noaa.gov/nsslnews/2018/10/video-advanced-technology-demonstrator/" target="_blank" rel="noopener">NOAA</a>] Radar research at the NOAA National Severe Storms Laboratory has taken another step forward. The Advanced Technology Demonstrator is installed at the National Weather Radar Testbed facility and will become fully operational in 2019.

https://www.youtube.com/watch?v=Xso-P0UAE88

The Advanced Technology Demonstrator, or ATD, is the first full-scale, S-band, dual-polarization phased array radar built from the ground up and designed specifically for use as a weather radar.

A <a href="https://www.nssl.noaa.gov/tools/radar/mpar/">phased array radar</a> is able to steer the radar beam electronically left-to-right and up-and-down while the antenna remains stationary. The ATD has a flat, or planar, antenna comprised of 76 panels with 4,864 radiating elements.

<img class="alignnone wp-image-98737 size-full" src="https://media.weathernationtv.com/app/uploads/2018/10/mpar-sk2.png" alt="New Advanced Technology Radar Installed at National Severe Storms Laboratory" width="600" height="334" />

[Phased Array radar has a unique antenna that collects the same information as a conventional radar in about one-sixth the time. Users can direct radar beams to scan different targets as needed. Researchers believe phased array could extend warning lead times from 10 minutes to 18-22 minutes.]

In addition, the ATD features <a href="https://www.nssl.noaa.gov/tools/radar/dualpol/">dual polarization technology</a> developed at NSSL and recently added to WSR-88D radars, also known as NEXRAD, throughout the country. The ATD is adding dual polarization technology to phased array technology, combining the benefits of both. The new radar will feature dual-polarization’s ability to show the size and shape of precipitation, and the phased array’s faster updates.

[Difference between conventional and polarmetric radar]

The radar will be used for meteorological studies and to help researchers evaluate polarimetric performance of a planar phased array radar.
