As the Atlantic hurricane season enters its final stretch,&nbsp;a new tropical storm has been named in the central Atlantic Ocean. Melissa, which is moving westward at around 15 to 20 mph, has drawn attention from the National Hurricane Center (NHC) due to its likely impacts in the Caribbean in the short term. They will begin issuing advisories and alerts soon. <div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1980637739553866070" src="https://x.com/NHC_Atlantic/status/1980637739553866070"></div>Melissa 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.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web1-1761041018957.png"><video src="https://media.weathernationtv.com/app/uploads/2025/10/east carib-1761016450984.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 when it develops? 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.

Tropical Storm Melissa Named in the Caribbean

An area of low pressure that's looking for it way is sitting and spinning off of the coast of California. As it gets kicked inland later this week, it's going to bring the unsettled weather with it. It will bring some beneficial rain and snow to parts of the southwest, including California and Colorado. A few inches of snow will be possible in the Sierra Nevada mountains as well as the western slope of the Colorado Rockies. <img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-21 071341-1761052447908.png">However, it's where that system ends up by the weekend that is raising some eyebrows. As this system emerges out of the Rockies, it will be moving into notably warmer temperatures, which could be just enough to power storms into the severe threshold. <img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-21 071527-1761052563825.png">But will this system have enough ingredients to talk about another weekend severe weather event? The Storm Prediction Center is already highlighting areas of the panhandle of Texas and western Oklahoma for a low-end threat by Thursday<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-21 071713-1761052641260.png">However, getting beyond four and five days out can be a little murky. Right now, this feels like a repeat of last weekend's storms, with all modes on the table. One thing we are starting to firmly grasp is the rainfall amounts will add up!<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-21 071908-1761052783499.png">With multiple rounds of storms expected, flash flooding will need to be monitored, especially in eastern Oklahoma and east Texas. Here's a first look at what storms could look like Thursday through Saturday<video src="https://media.weathernationtv.com/app/uploads/2025/10/2025-10-21 07-20-27-1761052878793.mp4" controls="true" width="100%"></video>There is loads of time for all of this to change, but start thinking about where the end of the week is going to take you. Do you have high school football game plans or trunk or treating? Those could be impacted by some of these potential storms.

NORTHWEST - As we head through the work week, we'll have some dry time Tuesday and Wednesday before our next frontal boundary takes aim at the Pacific Northwest on Thursday. Models have a couple of heavy plumes of rain, the first on Thursday and the second on Friday in the Pacific Northwest.<video src="https://media.weathernationtv.com/app/uploads/2025/10/2025-10-21 04-15-29-1761041749001.mp4" controls="true" width="100%"></video>According to the National Weather Service, this next event will be considered another "atmospheric river" because of the richness of the moisture being funneled in from the Pacific. On the AR (atmospheric river) forecast scale, we'll be between an AR2 and an AR3 along the West Coasts of Oregon and Washington State.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web2-1761041791714.png">Based on the AR scale, an AR3 is a balance of both beneficial and hazardous.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-19 164231-1760913773685.png">We spoke with the National Weather Service about total precipitation totals, and here's what they had to say about that.<video src="https://media.weathernationtv.com/app/uploads/2025/10/SOT_TRT_0.46_THIS FAR OUT WE CAN STILL EXPECT MULTIPLE INCHES OF RAIN IN WESTERN WASHINGTON_BD_E101925-1760913519296.mp4" controls="true" width="100%"></video>The Weather Prediction Center has been forecasting rainfall totals of a couple of inches as well, and our in-house forecast models show the snowfall totals in the higher elevations receiving several inches too.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web5-1761041823049.png"><img src="https://media.weathernationtv.com/app/uploads/2025/10/Web1-1761041886161.png">Be sure to join us LIVE on WeatherNation for the latest forecast!

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 through the Midwest and into the Great Lakes.<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 through the Upper Midwest, 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/2025/10/2025-10-21 04-09-32-1761041399038.mp4" controls="true" width="100%"></video>Wind alerts, including high wind alerts, have been issued for the High Plains through Tuesday for winds of 40 mph and gusts upwards of 60 mph.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web1-1761041458089.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.<video src="https://media.weathernationtv.com/app/uploads/2025/10/2025-10-21 04-11-12-1761041499503.mp4" controls="true" width="100%"></video><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/2025/10/2025-10-21 04-13-25-1761041636746.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>

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.

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 for severe weather, not much is expected behind this front.

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.

Have you noticed the heat in Oregon, specifically Portland? Well, it's not just you! The city has had its most 90-degree days on record.

https://twitter.com/NWSPortland/status/1032384600696213504

Just three years ago the city established its record of 29 days with high temperatures at or above 90 degrees. On Wednesday Portland hit 93°, well above the average high temperature of 81°.

How much longer will the heat last?

<img class="alignnone wp-image-95861 size-full" src="https://media.weathernationtv.com/app/uploads/2018/08/2-18.jpg" alt="Hot Summer: Most 90° Days Observed in Portland" width="1920" height="1080" />

Good news! That's if you aren't a fan of the heat. Cooler weather will move in for Thursday, August 23 to Tuesday, August 28 where low temperatures are forecast along the blue line and high temperatures along the red line. This will take us nearly through the end of the month, whereas September begins with an average high of 79 degrees.

<img class="alignnone wp-image-95862 size-full" src="https://media.weathernationtv.com/app/uploads/2018/08/1-19.jpg" alt="Hot Summer: Most 90° Days Observed in Portland" width="1920" height="1080" />

While the temperatures drop, the forecast remains mainly dry. There is an increased chance of showers by the weekend, then drying and warming next week.

<img class="alignnone wp-image-95863 size-full" src="https://media.weathernationtv.com/app/uploads/2018/08/4-17.jpg" alt="Hot Summer: Most 90° Days Observed in Portland" width="1920" height="1080" /><img class="alignnone wp-image-95864 size-full" src="https://media.weathernationtv.com/app/uploads/2018/08/5-6.jpg" alt="Hot Summer: Most 90° Days Observed in Portland" width="1920" height="1080" />

Long range forecasts are showing a *higher* chance of cooler weather for the Pacific Northwest through the beginning of September, including Portland. We may have broken the 90 degree day record Wednesday, while feeling the last of the 90 degree heat for the year!
